I know that you can check to see if an id (or other selector) has a certain class:
$('#mydiv').hasClass('bar')
But can you check to see if a class also has another class? Like:
$('.myclass').hasClass('bar')
Just wondering?

This is trivial to test. See it working on jsFiddle (a great online tool for web developers).
<div id="mydiv" class="myclass bar">
</div>
jQuery:
alert($('.myclass').hasClass('bar'))

Or skip the check and just select the elements instead.
$('.myclass.bar')
If you need to check for existence:
$('.myclass.bar').length > 0

Yes it works
if ($('.myclass').hasClass('bar')) {
//do some thing
}
Comments
you can try like this
if($('.myclass').find('bar').length > 0)
//Do you code
hope this helps you

will always be true. You need to check length
A class cannot have another class, only an element (that you get with its selector) can have multiple classes.
In order to check if #mydiv which has the class bar also has the class foo you can write something like:
if( $('#mydiv.bar').hasClass('foo') ) {
// ...
}

Yes it will work

.myclassthis will return true as long as one of them has.bar
