Compare 'e.target' to a jQuery object

To check if e.target has this class you can use the hasClass function.

if ($(e.target).hasClass("selector"))

Or, if you really want to compare objects, note that jQuery selectors return a collection of items, so I think you'll want

if (e.target === $('.selector')[0])

You're close. Use .is() instead:

if($(e.target).is('.selector')) {
    // Your code
}

The trick here is that you wrap e.target in a jQuery object to allow it access to all the useful jQuery methods.

If you're just seeing whether e.target has a certain class, try using .hasClass() in place of .is():

if($(e.target).hasClass('selector')) {
    // Your code
}

Either method works, although .hasClass() is a little clearer as to what the code does, and is faster than using .is()
