[jQuery] Remove element attribute

[Adrian Lynch]

Using attr(key, value) I can disable a button like so:

$("#myButton").attr("disabled", "disabled");

which results in:

<button id="myButton" disabled="disabled">My button</button>

But when I want to reverse this I do the following:

$("#myButton").attr("disabled", "");

which produces this:

<button id="myButton" disabled="">My button</button>

How can I remove the disabled attribute altogther?

Thanks.
