I'm trying to access the data-url attribute of the following element so it could be replaced upon callback or as needed with jQuery / Javascript.

What method will work to do this?

<a id="twitter_link" href="" class="twitter-share-button" data-via="imdto" data-lang="en" data-url="">Tweet</a>

I've tried using attr(), prop() functions but returns undefined.

You need to use the data function (for example):

$(myElement).data('url')

What version of jQuery are you using? In the latest version, it works like so:

$("#twitter_link").attr( "data-url" );

Awesome example! http://jsfiddle/shanabus/taGBL/1/

try to read the attribute with $('#twitter_link').data('url');
