It seems some people are landing here, and simply want to know if an element exists (a little bit different to the original question).. That's as simple as using any of the browser's selecting method, and checking it for a truthy value (generally).. For example, if my element had an id of "find-me", I could simply use. var elementExists = document.getElementById("find-me"); Similarly, if an existing element that doesn't match names has its set of classes adjusted so that it matches, it better still: var inputs = document.getElementsByTagName('input'), returns a nodelist, from which you can extract both elements like so: var pass = inputs.item('pass').
