i had written a client side javascript validation function for key validation by capturing the ascii value of the keys pressed by the user, so that i can allow or disallow him to press a specific key(event.keyCode for IE & event.which for Netscape). <BR>Myself & other teammates are using this function for key validation. but the problem is SOMETIMES(not always) it doesn&#039t work on the Netscape browser & whereas it works perfectly for IE.
