Remove classname from element with javascript

Question

I found the following regex from another Stack Overflow question: Change an element's class with JavaScript

And have used it in part of my script with success, h

That's because replace doesn't actually modify the string you call it on; rather, it returns a new string. So:

     foo.className = foo.className.replace( /(?:^|\s)bar(?!\S)/ , '' )

(By the way, you don't actually need to do this in raw JavaScript, since jQuery objects offer a removeClass method: http://api.jquery.com/removeClass/. So you could write:

     $('#foo').removeClass('bar');

or:

     $(foo).removeClass('bar');

)
