You're right. They are two separate objects, and two objects never compare
identically.

It's no different from this:

var obj = {}, a1 = [obj], a2 = [obj];

Now a1 !== a2, but a1[0] === a2[0].

But the real question is why do you want to do that?

Instead of calling $('#saveForm') repeatedly, call it once and save the
jQuery object.

   var $saveForm = $('#saveForm');

Now use $saveForm everywhere that you would have used $('#saveForm').
