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?

To disable a button using only JavaScript you need to set its disabled property to false . For example: element. disabled = true . And to enable a button we would do the opposite by setting the disabled JavaScript property to false .
You can disable the <button> element in HTML by adding the disabled attribute to the element. The disabled attribute is a boolean attribute that allows you to disable an element, making the element unusable from the browser.
1.1 To disable a submit button, you just need to add a disabled attribute to the submit button. $("#btnSubmit"). attr("disabled", true); 1.2 To enable a disabled button, set the disabled attribute to false, or remove the disabled attribute.
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.
