jQuery Filter Objects by Data Attribute Value

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. https://jsfiddle.net/qgwnY/

Thanks Vlad.

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

Check this out on jsfiddle.
