Implement MooTools’ Elements.addEvent in jQuery

By  on  

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

  1. More concise :

    jQuery.fn.addEvent = jQuery.fn.bind;

  2. Well put Pierre…well put.

  3. I too prefer verbs like el.setStyle v. el.css. But swapping syntax would totally goof me up!

  4. I don’t get it, why not just use

    $('#myelement').bind('click', function() {...});
    

    It’s even shorter than ‘addEvent’

  5. I agree with Corey, $().bind is exactly what you’re looking for…

  6. Bo Hunter

    I would have to agree, this is nothing more than an alias.

  7. 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.
