>Your outermost array isn't being used as an array, it's being used as an object with named properties. As explained in the first paragraph of <http://docs.jquery.com/Utilities/jQuery.each>, $.each will see that it is an array, and try to iterate over its elements by numeric index, but as its length is zero, there aren't any. Change your outermost array to an object, and it should work: var myStuff = {}; myStuff['somestring'] = []; myStuff['somestring'].push(1); myStuff['somestring'].push(2); myStuff['somestring'].push(3); $.each(myStuff, function(key, value) { alert(key + ": " + value); // shows "somestring: 1,2,3" }); Regards, Nick. -- Nick Fitzsimons http://www.nickfitz.co.uk/
