jQuery Mobile is a set of HTML5 based user interface systems that is built on top of jQuery. It is used for creating responsive and accessible websites and web apps for a variety of devices like mobiles, tablets, laptops, and desktops.
In this article, we will be using the jQuery Mobile panel beforeclose event that triggers when the process of closing the panel starts.
Syntax:
-
Initialize the panel with beforeclose callback specified:
$( ".selector" ).panel({ beforeclose: function( event, ui ) { // Your code here } }); -
Bind an event listener to the panelbeforeclose event:
$(".selector").on( "panelbeforeclose", 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.
