jquery .not() not working

Question

I'm trying to have something happen on every instance except where there is a disabled class, but .not() doesn't seem to work. Here is a short version of what I have:

if($(this).not('.Disabled')){
     -Do Something-
}

However, if I reverse it, i.e.

if($(this).is('.Disabled')){
     -Do Something-
}

then the "is" will work on an element with the class of "Disabled" Kind of confused where to go from here.

Answer 1

The .not method returns a jQuery object containing the elements in this set that don't match the selector.
It doesn't return a boolean.

In other words, it's the opposite of .filter, not .is.

You could write if ($(this).not('.Disabled').length) to check whether the jQuery object it creates is empty.

However, you should use the unary negation operator: if (!something)

Answer 2

You want to use hasClass to test if an element has a class:

if($(this).hasClass("disabled")) {
    // i am disabled
}

If you're talking about the disabled attribute, then use the :disabled selector:

if($(this).is(":disabled")) {
    // i am disabled
}
