jQuery Mobile Page beforecreate Event
jQuery Mobile is a set of HTML5-based user interface systems built on top of jQuery which is used for developing websites that are accessible on devices of various screen sizes like smartphones, tablets, desktops, and laptops.
In this article, we will be using the jQuery Mobile page beforecreate event which triggers before the creation of the page widget.
Syntax:
Initialize the page with the beforecreate callback specified.
$( ".selector" ).page({ beforecreate: function( event, ui ) { // Your code here. } });
Bind an event listener to pagebeforecreate event.
$(".selector").on( "pagebeforecreate", function( event, ui ) {} );
Parameters: It accepts a callback function that has two parameters.
- event: It accepts Event type value.
- ui: It accepts Object type value. The ui object can be empty but used for consistency with other events across the library.
