How do I determine if the .attr('class') exists?

I am using this code:

if(jQuery(this).attr('class') != undefined && jQuery(this).hasClass('myclass')) {

  //Do something

}

It doesn't seem to work.

It depends on what you want. Do you want to check if an element has the class attribute, such as:

<div class></div>

<div class=></div>

<div class=abc></div>

If so, use:

if ($('div').attr('class') != undefined)...

If you're trying to check if the element has a specific class, use:

if ($('div').hasClass('abc'))...
