How to check 'undefined' value in jQuery?

►
One option is to use typeof operator:

  1.  if (typeof val === "undefined") { // ... }
It returns a string indicating the type of the variable or other unevaluated operand. The main advantage of this method is that it will never raise an exception in case if variable val does not exist.
