jQuery UI Tabs activate Event
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 Tabs widget is used to create a single content area with multiple panels that are associated with a header in a list.
The jQuery UI Tabs activate event is used to trigger when a tab is activated. If the previously active tab will collapse, then ui.oldTab and ui.oldPanel will be empty objects and if the tabs are collapsing, ui.newTab and ui.newPanel will be empty jQuery objects.
The Tabs activate event accepts 2 values that are listed below:
- event: It represents the event for the tabs widget.
- ui: It is of an object type, and contains the following values:
- newTab: It represents the tab that is about to be activated.
- oldTab: It represents the tab that is about to be deactivated.
- newPanel: It represents the panel that is about to be activated.
- oldPanel: It represents the panel that is about to be deactivated.
Syntax:
Initialize the tabs with the activate callback:
$( ".selector" ).tabs({ activate: function( event, ui ) {} });
Bind an event listener to the tabsactivate event:
$( ".selector" ).on( "tabsactivate", function( event, ui ) {} );
