Can you give us the code on how you remove disabled? But here is an example from the top of my head.

<pre><code>&lt;button class="class" id="btn1" disabled&gt;

function remove_disable()
{
 document.getElementById('btn1').disabled = false;
 function2();
}
</code></pre>

then function2

<pre><code>function function2()
{
 //somecode
}
</code></pre>

Here, when we call remove_disable we remove the disabled feature on the button then run another function.

Hope this helps in a way

If you have control over when this change is done, a simple callback function would be the easiest solution.

Otherwise, you can use <a href="https://developer.mozilla.org/en/docs/Web/API/MutationObserver" rel="nofollow">Mutation Observers</a> to watch for when disabled property on inputs are changed.

You can use <code>Object.prototype.watch()</code>. It's supported in Firefox only, but <a href="https://gist.github.com/eligrey/384583" rel="nofollow">here's a polyfill</a>:

HTML:

<pre><code>&lt;button id="myButton" disabled="disabled"&gt;Click&lt;/button&gt;
</code></pre>

JavaScript:

<pre><code>var myButton = document.getElementById('myButton');
myButton.watch("disabled", function() {
 console.log("myButton changed!");
});

myButton.disabled = false; // "myButton changed" will be logged
</code></pre>

You can get notified of DOM changes by implementing a MutationObserver.

<pre><code>var observer = new MutationObserver(function(mutations) {
 if(mutations.some(function(m) { return m.attributeName == 'disabled' &amp;&amp; !m.target.disabled; }))
 {
 alert('Button was enabled');

observer.observe(targetButton, { attributes: true, childList: false, characterData: false });

The MutationObserver API lets you monitor elements for changes on the element.

<pre><code>var btnElement = document.getElementById("buttonId");

var observer = new MutationObserver(observerChanges);
observer.observe(btnElement, {
 attributes: true,
 subtree: opt.watchChildren,
 childList: opt.watchChildren,
 characterData: true
});

/// when you're done observing
observer.disconnect();

function observerChanges(mutationRecord, mutationObserver) {
 console.log(mutationRecord);
}
</code></pre>

I want a (preferably pure javascript but jquery is acceptable too) way to run a function when the <code>disabled="disabled"</code> property is removed from a button.
