Implement MooTools’ Elements.addEvent in jQuery
One thing that I've always disliked about the jQuery JavaScript framework is its syntax for adding event listeners to elements. The way to add a click event to an element using jQuery is:
$('#myElement').click(function() {
//do work
});
I love OOP so the above code tells me that a click is being triggered, not that it's going to add a listener to the element. There's nothing wrong with jQuery using that syntax; I simply don't prefer it. What I do when I need to work with jQuery is Moo-ify its syntax when I can. Here's how you can implement MooTools' "addEvent" syntax in MooTools.
The jQuery JavaScript
jQuery.fn.addEvent = jQuery.fn.bind; //updated
We add the "addEvent" function to the jQuery.fn object. Pretty simple.
The Usage
$(document).ready(function() {
$('#myElement').addEvent('click',function(){ alert('w00t'); });
});
Looks a lot like MooTools, no? If you like jQuery's syntax of .click() type events, read my post: Implementing jQuery-Like Event Syntax in MooTools

While synchronous code is easier to follow and debug, async is generally better for performance and flexibility. Why "hold up the show" when you can trigger numerous requests at once and then handle them when each is ready? Promises are becoming a big part of the JavaScript world...

I received an email from Ben Delaney a few weeks back about an interesting MooTools script he had written. His script was called FauxSelect and took a list of elements (UL / LI) and transformed it into a beautiful Mac-like SELECT element.
![MooTools: Set Style Per Media]()
I'd bet one of the most used MooTools methods is the setStyle() method, which allows you to set CSS style declarations for an element. One of the limitations of MooTools' setStyle() method is that it sets the specific style for all medias.
More concise :
jQuery.fn.addEvent = jQuery.fn.bind;
Well put Pierre…well put.
I too prefer verbs like el.setStyle v. el.css. But swapping syntax would totally goof me up!
I don’t get it, why not just use
$('#myelement').bind('click', function() {...});It’s even shorter than ‘addEvent’
I agree with Corey, $().bind is exactly what you’re looking for…
I would have to agree, this is nothing more than an alias.
Mysteriously enough in jQuery version 1.4 I get this:
$(“#website_stock”).addEvent is not a function
When I set it as just click(fn) it works in Firefox, but not in IE8. It doesn’t return any errors – just the functions do NOT run whatsoever. Same with the bind() option – works in FF on mac, not on IE8.
Hi David,
In this site, the two sides with name older and newer and toggle in-out,how to implement it please send me the complete demo with code if possible.
Thanks in advance
