How you might use jQuery to filter elements by their data Attribute values. This code snippet grabs all divs that have an id beginning with “proto_” and have a data attribute of “state” with value “open”.

var $el = $('div[id^=proto_]').filter(function()
{
     return ($(this).data("state") == "open")
});
console.log($el);

I’ve done a quick demo in jsfiddle to demonstrate. http://jsfiddle.net/qgwnY/

Thanks Vlad.

var $el = $('div[id^=proto_]').filter('div[data-state=open]').css('color','red');​

    Don’ forget that you can get the same result by using just:
    var $el = $(‘div[data-state=open]’) ;)
