Use created attribute with javascript in select list

Question

im trying to access an attribute that i created in a select list.

Answer 1

Try this:

var newUrl = document.getElementById('test').getAttribute('car');

EDIT

For the <select>, you have to look into the selected <option> element, not the <select> itself:

var select = document.getElementById('test');
select.options[select.selectedIndex].getAttribute('car');
