HTML

<div data-stuff="['a','b','c']"></div>

I want this to alert 'a'. It seems to alert '[' which suggest that jquery is not parsing it as an array. How is this possible? Am I going about this the best way. I want to pass this data from the serverside to this DOM element.

JavaScript

var stuff = $('div').data('stuff');
alert(stuff[0]);
