jQuery UI consists of GUI widgets, visual effects, and themes implemented using HTML, CSS, and jQuery. jQuery UI is great for building UI interfaces for the webpages. The jQuery UI Progressbar widget is used to add display the status of a determinate or indeterminate process.

The jQuery UI Progressbar create event is used to trigger when the progressbar value is created.

The Slider slide Event accepts two values that are listed below:

• event: It represents the event for the slider widget.
• ui: It is of an object type. The ui object is empty but it is added for consistency with other events.

Syntax:

Initialize the progressbar with the create callback:

$( ".selector" ).progressbar({
      create: function( event, ui ) {}
});

Bind an event listener to the progressbarcreate event:

$( ".selector" ).on( 
    "progressbarchange", 
    function( event, ui ) {} 
);

CDN Link: First, add jQuery UI scripts needed for your project.
