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.
Here is the simple syntax to use this method:
selector.triggerHandler( event, [data] ) |
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.
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> <button id="new">.triggerHandler("focus")</button><br/><br/> <input type="text" value="To Be Focused"/> </body> </html> |
To understand it in better way you can Try it yourself.
