Answer 1

You can jQuery's $.inArray and get rid of your $.each loop, and it works cross-browser (unlike Array.indexOf):

var index = $.inArray("test2", ["test1", "test2", "test3"]); // 1

(I realise your question is not tagged with 'jQuery', but you do mention that you're already using an $.each loop).
