I can easily disable a javascript button, and it works properly. My issue is that when I try to re-enable that button, it does not re-enable. Here's what I'm doing:

<script type=text/javascript>

    function startCombine(startButton) {



        startButton.disabled = 'true';



        startButton.disabled = 'false';



    }

</script>

<input type='button' id='start' value='Combine Selected Videos'

onclick='startCombine(this);'>

Why isn't this working, and what can I do to make it work?

true and false are not meant to be strings in this context.

You want the literal true and false Boolean values.

startButton.disabled = true;



startButton.disabled = false;

The reason it sort of works (disables the element) is because a non empty string is truthy. So assigning 'false' to the disabled property has the same effect of setting it to true.
