Equality testing in JQuery works no different from standard JavaScript.

!= means not equal to, but !== makes sure that both values have the same type as well. As an example, 1 == '1' is true but not 1 === '1', because the LHS value is a number and the RHS value is a string.

Given your example, we cannot really tell you a lot about what is going on. We need a real example.
