Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application is based on and claims priority to Chinese Patent Application No. 202110093219.0 filed on Jan. 25, 2021, the content of which is hereby incorporated by reference in its entirety into this disclosure. 
     TECHNICAL FIELD 
     The disclosure relates to the field of electronic device technologies, and more particularly, to a method for determining a location of a focus, an electronic device, and a storage medium. 
     BACKGROUND 
     Electronic devices such as smart TVs (televisions) are becoming more and more widely used. Smart TVs are TV products designed for satisfying diverse and specific needs of users. The smart TV, based on Internet application technologies, typically has an open operating system, an open chip, and an open application platform, to achieve two-way human-computer interactions and to integrate multiple functions such as audios, videos, entertainment, and data, which brings to users a more enjoyable experience. 
     Smart TV provides rich human-computer interactions. For example, in a page provided by smart TV (for example, operation interface or menu), users are allowed to move a focus to windows, buttons, items, and other elements by operating up, down, left, and right through a remote control. 
     In the related art, in the method of moving the focus, all the elements on the page provided by the smart TV are collected, and related calculations are performed to determine the location of the focus. However, such method requires calculation on all the elements on the page. With the increased number of page elements, the moving operation of the focus will become too slow, which negatively affects user experience. 
     SUMMARY 
     Embodiments of a first aspect of the disclosure provide a method for determining a location of a focus. The method includes: obtaining a current location of the focus in an electronic device; determining a current page element located by the focus based on the current location of the focus; obtaining an instruction for controlling the focus; obtaining a movement direction of the focus based on the instruction; obtaining a layout direction of the current page element; returning to a parent page element of the current page element in response that the movement direction of the focus is inconsistent with the layout direction; and determining the location of the focus in the parent page element. 
     Embodiments of a second aspect of the disclosure provide an electronic device. The electronic device includes: a processor and a memory for storing instructions executable by the processor.

     The method for determining the location of the focus, the apparatus for determining the location of the focus, and the electronic device in the embodiments of the disclosure are described below with reference to the drawings. 
     The method for determining the location of the focus according to the embodiments of the disclosure may be executed by the electronic device. The electronic device may be a smart TV, or a tablet computer with a remote control, which is not limited herein. 
     In the embodiments of the disclosure, the electronic device may be provided with a processing component, a storage component, and a driving component.

       FIG. 1  is a flowchart of a method for determining a location of a focus according to some embodiments of the disclosure. 
     The method for determining the location of the focus in the embodiments of the disclosure is executed by the apparatus for determining the location of the focus in the embodiments of the disclosure. The apparatus may be configured in the electronic device to obtain the current location of the focus in the electronic device, determine the current page element located by the focus based on the current location of the focus, obtain the instruction for controlling the focus, obtain the movement direction of the focus based on the instruction, obtain the layout direction of the current page element, return to the parent page element of the current page element in response that the movement direction of the focus is inconsistent with the layout direction, and determine the location of the focus in the corresponding parent page element, thereby improving the speed and accuracy of the movement of the focus. 
     As illustrated in  FIG. 1 , the method for determining the location of the focus includes the following. 
     At block  101 , a current location of the focus in an electronic device is obtained. The electronic device may be a smart TV. 
     It should be noted that the focus described in some embodiments may be the focus of the smart TV, that is, the focus may follow up, down, left, and right operations of the remote control of the user in the operation interface or menu of the smart TV, to move to corresponding windows, buttons, images, entries, and other elements, so that the element become the focus state, and the element that becomes the focus state may be clicked or subjected to other further operations. Visually, the element with the focus state may be added with diverse visual effects such as focus frame (or box) or color change, which intuitively follows the up, down, left, and right operations of the remote control to move on the interface of the smart TV, to achieve the corresponding human-computer interaction selection. The focus frame (or box) is more versatile and commonly used. 
     In some embodiments of the disclosure, the current location of the focus in the electronic device may be obtained based on a preset obtaining algorithm, and the preset obtaining algorithm may be calibrated based on actual conditions. 
     At block  102 , a current page element located by the focus is determined based on the current location of the focus. 
     In detail, when the user uses the remote control to operate the electronic device, the electronic device may obtain the current location of the focus in the electronic device based on the preset obtaining algorithm, and determine the current page element located by the focus based on the current location of the focus, i.e., the element that becomes the focus state. 
     At block  103 , an instruction for controlling the focus is obtained, and a movement direction of the focus is obtained based on the instruction. The movement direction may be one of up, down, left or right directions. 
     In some embodiments, the user sends the instruction through the remote control. For example, the user operates up, down, left or right button of the remote control, and the corresponding instruction is generated and sent to the electronic device. The remote control may be a Bluetooth remote control or an infrared remote control. 
     In detail, when the user uses the remote control to control the electronic device, the user operates the up, down, left or right button of the remote control, and the corresponding instruction is generated and sent to the electronic device. After determining the current page element located by the focus, the electronic device obtains (receives) the instruction, and parses the instruction to obtain the movement direction of the focus. 
     It should be noted that the movement direction of the focus in the embodiments corresponds to the up, down, left or right button of the remote control. For example, when the user sends the instruction by operating on the up button of the remote control, the movement direction of the focus obtained by the electronic device through parsing the instruction is upward. When the user sends the instruction by operating on the left button of the remote control, the movement direction of the focus obtained by the electronic device through parsing the instruction is left. 
     At block  104 , a layout direction of the current page element is obtained. 
     The layout direction may be horizontal or vertical. 
     For example, as illustrated in  FIG. 2 , it is assumed that the current page element is element B, and the layout direction of element B is horizontal, that is, elements b 1 , b 2 , b 3 , and b 4  are arranged horizontally. It is assumed that the current page element is element X 1 , and the layout direction of element X 1  is vertical, that is, elements A, B, and C are arranged horizontally. In other words, the layout direction of the current page element may be the layout direction of next sub-elements in the current page element. 
     It should be noted that the layout direction of the current page element described in some embodiments may be an inherent attribute of the current page, which may be obtained directly. The inherent attribute may be an attribute defined in the code by those skilled in the art when designing the page. In other words, the layout direction of the page element is fixed after the design of the page is completed. 
     In detail, when the user uses the remote control to operate the electronic device, after the electronic device obtains the movement direction of the focus, the inherent attribute of the current page is obtained, and the inherent attribute is analyzed to obtain the layout direction of the current page element. 
     It should be noted that when the page is loaded by the electronic device (that is, the electronic device executes the generated code of the page), the relevant inherent attribute is generated, and the inherent attribute is provided to the electronic device for direct obtaining (calling). 
     At block  105 , a parent page element of the current page element is returned to in response that the movement direction of the focus is inconsistent with the layout direction, and the location of the focus in the parent page element is determined. 
     In some embodiments of the disclosure, when the movement direction is upward or downward, the movement direction is consistent with the layout direction when the layout direction is vertical. When the movement direction is left or right, the movement direction is consistent with the layout direction when the layout direction horizontal. 
     Further, in some embodiments of the disclosure, the method for determining the location of the focus may further include: determining the location of the focus in the current page element in response that the movement direction of the focus is consistent with the layout direction and a side of the movement direction of the focus is not an edge of the current page element. 
     In detail, when the user uses the remote control to operate the electronic device, the electronic device directly obtains the layout direction of the current page element after obtaining the movement direction of the focus, and determines whether the movement direction of the focus is consistent with the layout direction. In response that the movement direction of the focus is inconsistent with the layout direction, it may return to the parent page element of the current page element, and the location of the focus is determined in the corresponding parent page element. The electronic device moves the focus to the page element at that location, that is, the page element at this location becomes the focus state. In response that the movement direction of the focus is consistent with the layout direction, it is further determined whether the side of the movement direction of the focus is the edge of the current page element. If the side of the movement direction of the focus is not the edge of the current page element, the location of the focus is determined in the current page element, and the electronic device moves the focus to the page element at that location, that is, the page element at that location becomes the focus state. 
     As illustrated in  FIG. 2 , it is assumed that the current location of the focus is the location of element b 1  (that is, element b 1  is in the focus state), the current page element is element B, and the layout direction of element B is horizontal. In response that the movement direction of the focus is upward, it is determined that the movement direction of the focus is inconsistent with the layout direction of element B, parent page element X 1  of element B is returned to, and the location of the focus may be determined in element X 1 , and then the focus is moved to the page element at that location. 
     In response that the movement direction of the focus is left, it is determined that the movement direction of the focus is consistent with the layout direction of element B, and the side of the movement direction is not the edge of element B, the location of the focus may be determined in element B, and then the focus may be moved to the page element at that location. 
     In some embodiments of the disclosure, the current location of the focus in the electronic device is obtained, and the current page element located by the focus is determined based on the current location of the focus, and then the instruction for controlling the focus is obtained, and the movement direction of the focus is obtained based on the instruction. The layout direction of the current page element is obtained. In response that the movement direction of the focus is inconsistent with the layout direction, it may return to the parent page element of the current page element, and the location of the focus is determined in the corresponding parent page element. As a result, the movement location of the focus may be quickly and accurately determined through the layout direction of the current page element and the movement direction of the focus, thereby improving the speed and accuracy of the movement of the focus, and enhancing the user experience. 
     In order to clearly illustrate the above embodiments, in some embodiments of the disclosure, as illustrated in  FIG. 3 , determining the location of the focus in the current page element may include the following. 
     At block  301 , a plurality of second page sub-elements in the current page element are obtained. 
     As illustrated in  FIG. 4 , it is assumed that the current page element is B, and a plurality of second page sub-elements may be b 1 , b 2 , b 3 , and b 4 . Elements b 1 , b 2 , b 3 , and b 4  are the smallest elements in the page. For example, if the page is a TV show selection page, elements b 1 , b 2 , b 3 , and b 4 , and elements a 1 , a 2 , a 3 , and a 4  may be TV shows, and element B and element A are virtual elements. It should be noted that the virtual elements described in some embodiments may be defined in the code by those skilled in the art when designing the page, and the smallest elements in the virtual element are in a row or column. 
     At block  302 , a plurality of second distances between the plurality of second page sub-elements and the current location of the focus are obtained. 
     In some embodiments of the disclosure, the plurality of second distances between the plurality of second page sub-elements and the current location of the focus are calculated based on a preset distance algorithm, where the preset distance algorithm is calibrated based on actual conditions. 
     At block  303 , a target second page sub-element corresponding to a shortest distance of the plurality of second distances is determined, and the focus is kept on the target second page sub-element. 
     In detail, when the user uses the remote control to operate the electronic device, in response that the movement direction of the focus is consistent with the layout direction and the side of the movement direction of the focus is not the edge of the current page element, the plurality of second page sub-elements in the current page element are obtained, and the plurality of second distances between the plurality of second page sub-elements and the current location of the focus are determined based on the preset distance algorithm. The shortest second distance is determined from the plurality of second distances, and the target second page sub-element corresponding to the shortest distance of the plurality of second distances is determined. The focus is kept on the target second page sub-element, that is, the target second page sub-element becomes the focus state. 
     As illustrated in  FIG. 4 , it is assumed that the current location of the focus is the location of element b 1  (that is, element b 1  is in the focus state), and the current page element is element B, where the layout direction of element B is horizontal. When the movement direction of the focus obtained by the electronic device is right, the electronic device determines that the movement direction of the focus is consistent with the layout direction of element B, and the side of the movement direction of the focus is not the edge of element B. Distances between element b 1  and element b 2 , element b 1  and element b 3 , and element b 1  and element b 4  (i.e., the distance  1 ,  2  and  3 ) are calculated respectively, and the shortest distance is obtained. Based on the shortest distance, it is determined that the target second page sub-element is element b 2 , and the focus remains on element b 2  (that is, element b 2  becomes the focus state). Therefore, it may calculate the sub-elements in element B only, which greatly reduces the amount of calculation, so that the location of the focus may be quickly determined. 
     In some embodiments, as illustrated in  FIG. 5 , determining the location of the focus in the current page element includes the following. 
     At block  501 , a plurality of fourth page sub-elements in the current page element are obtained. 
     As illustrated in  FIG. 2 , it is assumed that the current page element is B, and the plurality of fourth page sub-elements may be b 1 , b 2 , b 3 , and b 4 . 
     At block  502 , a loading sequence of the plurality of fourth page sub-elements is obtained, and a plurality of second priorities between the plurality of fourth page sub-elements and the current location of the focus are determined based on the loading sequence. 
     It should be noted that the loading sequence in some embodiments is calibrated based on a loading strategy of page design, where the loading strategy is calibrated based on requirements by the relevant page developer. In addition, when the page is loaded by the electronic device (that is, the electronic device executes the generated code of the page), the loading sequence of various elements in the page is provided to the electronic device for direct obtaining (calling) when needed. 
     At block  503 , a target fourth page sub-element corresponding to a highest priority of the plurality of second priorities is determined, and the focus is kept on the target fourth page sub-element. 
     In detail, when the user uses the remote control to operate the electronic device, and when the electronic determines that the movement direction of the focus is consistent with the layout direction, and the side of the movement direction of the focus is not the edge of the current page element, the plurality of fourth page sub-elements in the current page element are obtained, the loading sequence of the plurality of fourth page sub-elements is obtained, the plurality of second priorities between the plurality of fourth page sub-elements and the current location of the focus are determined based on the loading sequence, the target fourth page sub-element is determined based on the highest priority from the plurality of second priorities, and the focus is kept on the target fourth page sub-element, that is, the target fourth page sub-element becomes the focus state. 
     As illustrated in  FIG. 2 , it is assumed that the current location of the focus is the location of element b 1  (that is, element b 1  is in the focus state), the current page element is element B, and the layout direction of element B is horizontal. When the movement direction of the focus obtained by the electronic device is right, the electronic device determines that the movement direction of the focus is consistent with the layout direction of element B, and the side of the movement direction of the focus is not the edge of element B. The loading sequence of element b 2 , element b 3  and element b 4  are obtained, the element loaded first is used as the target element (that is, the target fourth page sub-element), and the focus remains on the target element (that is, the target element becomes the focus state). 
     In some embodiments, the method for determining the location of the focus may further include: in response that the movement direction of the focus is consistent with the layout direction, and the side of the movement direction of the focus is the edge of the current page element, returning to the parent page element of the current page element, and the location of the focus is determined in the corresponding parent page element. 
     Returning to the parent page element of the current page element, and determining the location of the focus in the corresponding parent page element includes: returning to a previous page element of the current page element, and determining the location of the focus in the previous page element. 
     In detail, when the user uses the remote control to operate the electronic device, if the electronic device determines that the movement direction of the focus is consistent with the layout direction, and the side of the movement direction of the focus is the edge of the current page element, it may return to the previous page element of the current page element, and the location of the focus is determined in the previous page element. 
     As illustrated in  FIG. 6 , it is assumed that the current location of the focus is the location of element b 1  (that is, element b 1  is in the focus state), and the current page element is element B, where the layout direction of element B is horizontal. When the movement direction of the focus obtained by the electronic device is left, the electronic device determines that the movement direction of the focus is consistent with the layout direction of element B, and the side of the movement direction of the focus is the edge of element B, it may return to previous page element X 1  of element B. Element X 1  includes element A, element B, and element C. At this time, the target element in element X 1  is determined based on the preset algorithm, for example, the target element is determined to be element A. The electronic device calculates the distances between element b 1  and element a 1 , element b 1  and element a 2 , element b 1  and element a 3 , and element b 1  and element a 4  respectively, and obtain the shortest distance, and then element a 1  is determined as the location of the focus based on the shortest distance. Alternatively, the electronic device may obtain the loading sequence of element a 1 , element a 2 , element a 3  and element a 4 , and determine the location of the focus based on the loading sequence, for example, moving to element a 1 . 
     It should be noted that the preset algorithm described in some embodiments is calibrated based on actual conditions. For example, the preset algorithm may be written by relevant person who designed the webpage, and the preset algorithm includes changing the movement direction of the focus. For example, the direction changes from left to upward, or from right to downward, which is not limited herein. In addition, the preset algorithm may include determining whether an element exists in the movement direction of the focus, and if there is the element exists in the movement direction of the focus, the element closest to the focus may be used as the target element. 
     As illustrated in  FIG. 11 , it is assumed that the current location of the focus is the location of element b 4  (that is, element b 4  is in the focus state), and the current page element is element B, where the layout direction of element B is horizontal. When the movement direction of the focus obtained by the electronic device is right, the electronic device determines that the movement direction of the focus is consistent with the layout direction of element B, and the side of the movement direction of the focus is the edge of element B, it may return to previous page element X 1  of element B. Element X 1  includes element A, element B, element C, and element D. At this time, the target element in element X 1  is determined as element D based on the preset algorithm, and then the electronic device calculates the distances between element b 4  and element d 1 , element b 4  and element d 2 , and element b 4  and element d 3  respectively, and the shortest distance is obtained, and then element d 2  is determined as the location where the focus moves to, based on the shortest distance. Alternatively, the electronic device may obtain the loading sequence of element d 1 , element d 2 , and element d 3 , and determine the location of the focus based on the loading sequence, for example, moving to element d 1 . 
     In some embodiments of the disclosure, returning to the parent page element of the current page element, and determining the location of the focus in the corresponding parent page element, may include: returning to a previous page element of the current page element; and determining the location of the focus in the previous page element in response that a layout direction of the previous page element is consistent with the movement direction of the focus. 
     In detail, when the user uses the remote control to operate the electronic device, the electronic device may return to the previous page element of the current page element and obtain the layout direction of the previous page element in response that the movement direction of the focus is inconsistent with the layout direction, and determines whether the layout direction of the previous page element is consistent with the movement direction of the focus. If the layout direction of the previous page element is consistent with the movement direction of the focus, the location of the focus is determined in the previous page element. 
     In order to clearly illustrate the above embodiments, in some embodiments of the disclosure, as illustrated in  FIG. 7 , determining the location of the focus in the corresponding parent page element may include the following. 
     At block  701 , a plurality of first page sub-elements in the parent page element are obtained. 
     As illustrated in  FIG. 8 , it is assumed that the current location of the focus is the location of element b 1  (that is, element b 1  is in the focus state), the current page element is element B, and the movement direction of the focus is upward. The plurality of first page sub-elements of parent page element X 1  are a 1 , a 2 , a 3  and a 4 . Element X 1  may include three lower-level sub-elements, namely, element A, element B and element C. 
     At block  702 , a plurality of first distances between the plurality of first page sub-elements and the current location of the focus are obtained. 
     In some embodiments of the disclosure, the plurality of first distances between the plurality of first page sub-elements and the current location of the focus may be calculated based on a preset distance algorithm. 
     At block  703 , a target first page sub-element corresponding to a shortest distance of the plurality of first distances is determined, and the focus is kept on the target first page sub-element. 
     In detail, when the user uses the remote control to operate the electronic device, when the electronic device determines that the layout direction of the previous page element is consistent with the movement direction of the focus, the target page element is determined from the previous page element based on the movement direction of the focus (for example, element A in  FIG. 8 ). The plurality of first page sub-elements in the target page element are obtained, and the plurality of first distances between the plurality of first page sub-elements and the current location of the focus is calculated based on the preset distance algorithm. The shortest distance in the plurality of first distances is determined based on the plurality of first distances. The target first page sub-element is determined based on the shortest distance, and the focus is kept on the target first page sub-element, that is, the target first page sub-element becomes the focus state. 
     As illustrated in  FIG. 8 , it is assumed that the current location of the focus is the location of element b 1  (that is, element b 1  is in the focus state), and the current page element is element B, where the layout direction of element B is horizontal, and the layout direction of parent page element X 1  of element B is vertical. In response that the movement direction of the focus obtained by the electronic device is upward, the electronic device may determine that the movement direction of the focus is inconsistent with the layout direction of element B, and then it may return to previous page element X 1  of element B. The electronic device may determine that the movement direction of the focus is consistent with the layout direction of element X 1 , and then the electronic device determines the target element based on the movement direction of the focus. Element X 1  includes element A, element B, and element C. At this time, the electronic device determines that the target element is element A, and then the electronic device calculates distances between element b 1  and element a 1 , element b 1  and element a 2 , element b 1  and element a 3 , and element b 1  and element a 4  (i.e., distance  1 ,  2 ,  3 , and  4 ), and obtains the shortest distance. The target first page sub-element is determined as element a 1  based on the shortest distance, and the focus is kept on element a 1  (i.e., element a 1  becomes the focus state). Therefore, it may calculate the sub-elements in the element A only, which greatly reduces the amount of calculation, so that the location of the focus may be quickly determined. 
     In some embodiments, as illustrated in  FIG. 9 , determining the location of the focus in the parent page element includes the following. 
     At block  901 , a plurality of third page sub-elements in the parent page element are obtained. 
     As illustrated in  FIG. 2 , it is assumed that the current location of the focus is the location of element b 1  (that is, element b 1  is in the focus state), the current page element is element B, the movement direction of the focus is upward, and the plurality of third page sub-elements of parent page element X 1  are a 1 , a 2 , a 3  and a 4 . Element X 1  may include three lower-level sub-elements, namely, element A, element B and element C. 
     At block  902 , a loading sequence of the plurality of third page sub-elements is obtained, and a plurality of first priorities between the plurality of third page sub-elements and the current location of the focus are determined based on the loading sequence. 
     At block  903 , a target third page sub-element corresponding to a highest priority of the plurality of first priorities is determined, and the focus is kept on the target third page sub-element. 
     In detail, when the user uses the remote control to operate the electronic device, and when the electronic device determines that the layout direction of the previous page element is consistent with the movement direction of the focus, the target page element may be determined from the previous page element based on the movement direction of the focus (for example, element A in  FIG. 2 ). The plurality of third page sub-elements in the target page element are obtained respectively, and the loading sequence of the plurality of third page sub-elements is obtained, and the plurality of first priorities between the plurality of third page sub-elements and the current location of the focus may be determined based on the loading sequence. The target third page sub-element is determined based on the highest priority from the plurality of first priorities, and the focus is kept on the target third page sub-element, that is, the target third page sub-element becomes the focus state. 
     As illustrated in  FIG. 2 , it is assumed that the current location of the focus is the location of element b 1  (that is, element b 1  is in the focus state), and the current page element is element B, where the layout direction of element B is horizontal, and the layout direction of parent page element X 1  of element B is vertical. In response that the movement direction of the focus obtained by the electronic device is upward, the electronic device may determine that the movement direction of the focus is inconsistent with the layout direction of element B, and return to previous page element X 1  of element B. The electronic device may determine the movement direction of the focus is consistent with the layout direction of element X 1 . The electronic device determines the target element based on the movement direction of the focus. Element X 1  includes element A, element B, and element C. At this time, the electronic device determines that the target element is element A, and obtains the loading sequence of element a 1 , element a 2 , element a 3 , and element a 4 . The element that is loaded first is used as the target element (that is, the target third page sub-element), and the focus is kept on the target element (that is, the target element becomes the focus state). 
     In some embodiments of the disclosure, the method for determining the location of the focus may further include: continuing to search for the parent page element until the parent page element whose movement direction is consistent with the movement direction of the focus is found in response that the layout direction of the previous page element is inconsistent with the movement direction of the focus; determining the location of the focus in the parent page element whose movement direction is consistent with the movement direction of the focus; and informing a user in response to no parent page element whose movement direction is consistent with the movement direction of the focus (for example, voice reminders and text reminders, which may be not limited herein). 
     In detail, as illustrated in  FIG. 10 , it is assumed that the current location of the focus is the location of element b 1  (that is, element b 1  is in the focus state), and the current page element is element B, where the layout direction of element B is horizontal, the layout direction of parent page element X 1  of element B is horizontal, and the layout direction of parent page element Y 1  of element X 1  is vertical. In response that the movement direction of the focus obtained by the electronic device is downward, the electronic device determines that the movement direction of the focus is inconsistent with the layout direction of element B, it may return to parent page element X 1  of element B. The electronic device determines that the movement direction of the focus is also inconsistent with the layout direction of element X 1 , it may return to parent page element Y 1  of element X 1 . The electronic device determines that the movement direction of the focus is consistent with the layout direction of element Y 1 , and the location of the focus is determined in parent page element Y 1  whose movement direction is consistent with the movement direction of the focus. 
     In some embodiments of the disclosure, the method for determining the location of the focus may further include: recording the current location of the focus in the current page element; and positioning the focus to the current location in response that the focus returns to the current page element. 
     In detail, when the user uses the remote control to operate the electronic device, the electronic device records the current location of the focus in the current page element, and when the focus returns to the current page element, the focus is positioned to the current location. 
     As illustrated in  FIG. 2 , it is assumed that the current location of the focus is the location of element b 1  (that is, element b 1  is in the focus state), and the current page element is element B, where the layout direction of element B is horizontal, and the layout direction of parent page element X 1  of element B is vertical. When the user uses the remote control to operate the electronic device, and when the focus is at the location of element a 4 , if the user sends a control instruction through the remote control to control the focus to move to the right, the focus jumps to element B. At this time, the electronic device positions the focus to the location of element b 1  based on the previous record. 
     It should be noted that, as illustrated in  FIG. 2 ,  FIG. 4 ,  FIG. 6 ,  FIG. 8 ,  FIG. 10 , and  FIG. 11 , elements such as element A, element B, element C, and element D that include the smallest elements are virtual elements. The virtual elements may be defined in the code by the relevant technicians when designing the page, and the smallest elements in elements such as element A, element B, element C, and element D are all set in a row or column. 
     With the method for determining the location of the focus provided in the embodiment of the disclosure, the current location of the focus in the electronic device is obtained, and the current page element located by the focus is determined based on the current location of the focus, and then the instruction for controlling the focus is obtained, and the movement direction of the focus is obtained based on the instruction. The layout direction of the current page element is obtained. In response that the movement direction of the focus is inconsistent with the layout direction, it may return to the parent page element of the current page element, and the location of the focus is determined in the corresponding parent page element. As a result, the movement location of the focus may be quickly and accurately determined through the layout direction of the current page element and the movement direction of the focus, thereby improving the speed and accuracy of the movement of the focus, and enhancing the user experience.
