Select element with specific data by using jQuery

Question

Is it possible to set some data by using the jQuery data method and then later query it? Something like ... find all elements with data foo == true?

Answer 1

You can use .filter() to select the elements you want, like this:

$("someSelector").filter(function() { return $.data(this, "foo"); });

In this case since you're checking a boolean it's very simple, for checking against a value just add the comparison, like this:

$("someSelector").filter(function() { return $.data(this, "foo") == "value"; });
