How to remove all CSS classes using jQuery/JavaScript?

Click Upvote picture Click Upvote · Sep 15, 2009 · Viewed 560k times · Source

Instead of individually calling $("#item").removeClass() for every single class an element might have, is there a single function which can be called which removes all CSS classes from the given element?

Both jQuery and raw JavaScript will work.

$("#item").removeClass();

Calling removeClass with no parameters will remove all of the item's classes.


You can also use (but is not necessarily recommended, the correct way is the one above):

$("#item").removeAttr('class');
$("#item").attr('class', '');
$('#item')[0].className = '';

If you didn't have jQuery, then this would be pretty much your only option:

document.getElementById('item').className = '';
