triggerHandler( event, [data] ) Method

Quiz

Description

The triggerHandler( event, [data] ) method triggers all bound event handlers on an element (for a specific event type) WITHOUT executing the browser's default actions, bubbling, or live events.

This method behaves very similarly to the trigger method, with two major exceptions −

First − No default browser actions are triggered, the triggered event does not bubble, and live events aren't triggered.
Second − The event is only triggered on the first element within the jQuery collection.

This method returns the return value of the triggered handler instead of a chainable jQuery object.

Syntax

Here is the simple syntax to use this method −

selector.triggerHandler( event, [data] )

Parameters

Here is the description of all the parameters used by this method −

event − An event object or type to trigger.
data − This is an optional parameters and represents additional data to pass as arguments (after the event object) to the event handler.

               $("<span>Focused!</span>").appendTo("body").fadeOut(1000);
            });
				
         });
