The jQuery-Mobile-Progress-Bar-with-Percentage is a plugin for jQuery Mobile which creates, manages, starts, stops, resumes and explicitly sets the value of a progress bar or creates an indefinite loading bar. In addition it provides the options to set the progress bar's outer theme and inner filling theme on the basis of the jQuery Mobile standard themes, to show a percentage completion counter, to set whether the progress bar has normal or mini size, to define the interval which specifies the filling frequency rate, to configure the max value of the outer bar and set the initial value of the filling inner bar. The JavaScript prototype chaining method is used in order to enable the chaining of separate method calls where each call is made on the same instance.
