 Description: Check if its a number
This is a simple and most effective JavaScript that can be added to your webpage to enable any of the form text box in any of the forms of your webpage to accept only numbers. The script prompts the user to re-enter a valid number by displaying the message” Please input a valid number” if the user gives a value other than a number into the form box. The script can work on Netscape 4.x and Internet Explorer 4.x browsers.
