Title: Set class in jQuery
Post by: live627 on July 10th, 2012, 08:15 AM

Is there an equivalent function in jQuery that does the same thing as className other than attr()?

You mean .hasClass('class')...?
Or simply .is('.class')? (A bit slower though.)
If you want to assign a class, use .addClass('class') or .toggleClass('class'). The opposite is .removeClass('class').
If you want to get a list of all classes, you'll have to rely on $()[0].className or $().attr('class'), AFAIK.

Hmm... okay. So there's no hidden magic function that I missed. Thanks anyway, Nao!

Well, there's nothing wrong is using className (or anything purely JS) even when jQuery equivalents are available. I usually choose to use jQ in these situations because the code is shorter and thus compresses better.

Speaking of which, I just finished rewriting Zoomedia... The code works much better, and is about 150 bytes shorter :D

Same in my case... I need to set a class to multiple elements at once, and I can use JQ's .attr(), which saves me typing.
