Check if an element contains a class in JavaScript?

Question

Using plain JavaScript (not jQuery), Is there any way to check if an element contains a class?

Currently, I\'m doing this:

Just to add to the answer for people trying to find class names within inline SVG elements.

Change the hasCLass() function to:

function hasClass(element, cls) {
    return (' ' + element.getAttribute('class') + ' ').indexOf(' ' + cls + ' ') > -1;
  }

Instead of using the className property you'll need to use the getAttribute() method to grab the class name.
