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.
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.
Example:
Following is a simple example a simple showing the usage of this method:<html>
<head>
<title>the title</title>
<script type="text/javascript"
src="/jquery/jquery-1.3.2.min.js"></script>
<script type="text/javascript" language="javascript">
$(document).ready(function() {
$("#old").click(function(){
$("input").trigger("focus");
});
$("#new").click(function(){
$("input").triggerHandler("focus");
});
$("input").focus(function(){
$("<span>Focused!</span>").appendTo("body").fadeOut(1000);
});
});
</script>
</head>
<body>
<button id="old">.trigger("focus")</button>
