Event detect when css property changed using Jquery

Question

Is there a way to detect if the "display" css property of an element is changed (to whether none or block or inline-block...)? if not, any plugin? Thanks

Note

Mutation events have been deprecated since this post was written, and may not be supported by all browsers. Instead, use a mutation observer.

Yes you can. DOM L2 Events module defines mutation events; one of them - DOMAttrModified is the one you need. Granted, these are not widely implemented, but are supported in at least Gecko and Opera browsers.

Try something along these lines:

```
document.documentElement.addEventListener('DOMAttrModified', function(e){
  if (e.attrName === 'style') {
    console.log('prevValue: ' + e.prevValue, 'newValue: ' + e.newValue);
  }
}, false);

document.documentElement.style.display = 'block';
```

You can also try utilizing IE's "propertychange" event as a replacement to `DOMAttrModified`. It should allow to detect `style` changes reliably.
