Find element's onclick event with javascript

Question

I need to clone the onclick event of an element from one link to another.

<a id='foo' onclick='bar'>

I need some javascript or jquery that will return `bar'.

$('#foo').attr('onclick')
    //returns 'undefined'

I get the full function returned as a string, not undefined: jsfiddle.net/Z4gAp. What browser are you using? (I'm using Chrome on a Mac) — Clive

This works fine for me: jsfiddle.net/purmou/73yns @Clive: Mine works just fine, it returns "bar." — Purag

Use the native .getAttribute method of the DOM element.

I have compared .attr('onclick') to [0].getAttribute('onclick'):

The jQuery method returned function onclick(event) {bar;} (jQuery version 1.5.2, included by Stack Overflow)
The JavaScript method returned "bar"

Test case (copy & paste in console):

$('<a id="foo" onclick="bar">')[0].getAttribute('onclick')

@JohnGiotta I tested the code in a console at Stack Overflow, which includes jQuery version 1.5.2 (Get version using $().jquery). See also, this fiddle: jsfiddle.net/3qkJr

It returns bar just fine in jQuery 1.6.4, where the prop method returns the full function instead. Solution would be to upgrade your jQuery to the newest version.
