jQuery UI Menu focus Event

Last Updated : 27 Jun, 2022

jQuery UI consists of GUI widgets, visual effects, and themes implemented using HTML, CSS, and jQuery. It is great for building UI interfaces for the webpages. The jQuery UI Menu widget creates a menu list that is used for mouse and keyboard interactions.

The jQuery UI Menu focus event triggers when a menu gains focus or when any menu item is activated.

The menu focus event accepts two values that are listed below.

event: It represents the event for the menu item.
ui: It is of an object type value.
- item: It represents the currently active item.

Syntax:

Initialize the menu with the focus callback.

$( ".selector" ).menu({
  focus: function( event, ui ) {}
});

Bind an event listener to the menufocus event.

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

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

<link rel=”stylesheet” href=”//code.jquery.com/ui/1.12.1/themes/smoothness/jquery-ui.css”>
<script src=”//code.jquery.com/jquery-1.12.4.js”></script>
<script src=”//code.jquery.com/ui/1.12.1/jquery-ui.js”></script>

Example: This example describes the uses of the jQuery UI menu focus event.
