In Java Script how to Check Null Value?
I want something for checking the null value. Actually I have just read that using the null parameters in Javascript allows programmers to define a variable without assigning a value to it. But I don't know anything about the checking that.!? Can anyone tell me how to Check Null Value in Java Script..?? It would be really appreciable if you provide some sample of the coding.! Thanks in Advance..!!
