DOM - DOMException Object

The DOMException represents an abnormal event happening when a method or a property is used.
Below table lists the properties of the DOMException object
name
Returns a DOMString that contains one of the string associated with an error constant (as seen the table below).
IndexSizeError
The index is not in the allowed range. For example, this can be thrown by the Range object. (Legacy code value: 1 and legacy constant name: INDEX_SIZE_ERR)
HierarchyRequestError
The node tree hierarchy is not correct. (Legacy code value: 3 and legacy constant name: HIERARCHY_REQUEST_ERR)
WrongDocumentError
The object is in the wrong document. (Legacy code value: 4 and legacy constant name: WRONG_DOCUMENT_ERR)
InvalidCharacterError
The string contains invalid characters. (Legacy code value: 5 and legacy constant name: INVALID_CHARACTER_ERR)
NoModificationAllowedError
The object cannot be modified. (Legacy code value: 7 and legacy constant name: NO_MODIFICATION_ALLOWED_ERR)
NotFoundError
The object cannot be found here. (Legacy code value: 8 and legacy constant name: NOT_FOUND_ERR)
NotSupportedError
The operation is not supported. (Legacy code value: 9 and legacy constant name: NOT_SUPPORTED_ERR)
InvalidStateError
The object is in an invalid state. (Legacy code value: 11 and legacy constant name: INVALID_STATE_ERR)
SyntaxError
The string did not match the expected pattern. (Legacy code value: 12 and legacy constant name: SYNTAX_ERR)
InvalidModificationError
The object cannot be modified in this way. (Legacy code value: 13 and legacy constant name: INVALID_MODIFICATION_ERR)
NamespaceError
The operation is not allowed by Namespaces in XML. (Legacy code value: 14 and legacy constant name: NAMESPACE_ERR)
InvalidAccessError
The object does not support the operation or argument. (Legacy code value: 15 and legacy constant name: INVALID_ACCESS_ERR)
TypeMismatchError
The type of the object does not match the expected type. (Legacy code value: 17 and legacy constant name: TYPE_MISMATCH_ERR) This value is deprecated, the JavaScript TypeError exception is now raised instead of a DOMException with this value.
SecurityError
The operation is insecure. (Legacy code value: 18 and legacy constant name: SECURITY_ERR)
NetworkError
A network error occurred. (Legacy code value: 19 and legacy constant name: NETWORK_ERR)
AbortError
The operation was aborted. (Legacy code value: 20 and legacy constant name: ABORT_ERR)
URLMismatchError
The given URL does not match another URL. (Legacy code value: 21 and legacy constant name: URL_MISMATCH_ERR)
QuotaExceededError
The quota has been exceeded. (Legacy code value: 22 and legacy constant name: QUOTA_EXCEEDED_ERR)
TimeoutError
The operation timed out. (Legacy code value: 23 and legacy constant name: TIMEOUT_ERR)
InvalidNodeTypeError
The node is incorrect or has an incorrect ancestor for this operation. (Legacy code value: 24 and legacy constant name: INVALID_NODE_TYPE_ERR)
DataCloneError
The object cannot be cloned. (Legacy code value: 25 and legacy constant name: DATA_CLONE_ERR)
EncodingError
The encoding operation, being an encoding or a decoding one, failed (No legacy code value and constant name).
NotReadableError
The input/output read operation failed (No legacy code value and constant name).
Following example demonstrates how using a not well-formed XML document causes a DOMException.
error.xml contents are as below −
<?xml version = "1.0" encoding = "UTF-8" standalone = "no" ?>
<Company id = "companyid">
   <Employee category = "Technical" id = "firstelement" type = "text/html">
      <FirstName>Tanmay</first>
      <LastName>Patil</LastName>
      <ContactNo>1234567890</ContactNo>
      <Email>tanmaypatil@xyz.com</Email>
   </Employee>
</Company>
Following example demonstrates the usage of the name attribute −
<html>
   <head>
      <script>
         function loadXMLDoc(filename) {
            if (window.XMLHttpRequest) {
               xhttp = new XMLHttpRequest();
            } else // code for IE5 and IE6 {
               xhttp = new ActiveXObject("Microsoft.XMLHTTP");
            }
            xhttp.open("GET",filename,false);
            xhttp.send();
            return xhttp.responseXML;
         }
      </script>
   </head>
   <body>
      <script>
         try {
            xmlDoc = loadXMLDoc("/dom/error.xml");
            var node  = xmlDoc.getElementsByTagName("to").item(0);
            var refnode = node.nextSibling;
            var newnode = xmlDoc.createTextNode('That is why you fail.');
            node.insertBefore(newnode, refnode);
         } catch(err) {
            document.write(err.name);
         }
      </script>
   </body>
</html>
Save this file as domexcption_name.html on the server path (this file and error.xml should be on the same path in your server). We will get the output as shown below −
