jQuery - select all elements with attribute name (not value) beginning with…?

Question

Say I\'m looking for all elements with an attribute \'data-language\', whose value begins with \'java\' (would match both \'java\' and \'javascript\'). I know how to do this

Answer 1

jQuery has a nice function for this.

http://api.jquery.com/data/

$("div").data() // returns all data attributes to this div
