jQuery Mobile is a web-based technology used to make responsive content that can be accessed on all smartphones, tablets, and desktops.
In this article, we will be using the jQuery Mobile Collapsible expand event to trigger when a collapsible widget is expanded.
Syntax:
Initialize the collapsible with the expand callback specified:
$( ".selector" ).collapsible({
expand: function( event, ui ) {}
});
Bind an event listener to the collapsibleexpand event:
$( ".selector" ).on( "collapsibleexpand",
function( event, ui ) {} );Parameters: It contains two parameters as mentioned above and discussed below:
- event: It accepts Event type value.
- ui: It accepts object type value. This value is empty as it is used for consistency with other events.
CDN Link: First, add jQuery Mobile scripts needed for your project.
