 regular expressions are the way to go with this sort of thing, try
Code:
if ( /[^0-9]/.test(fn) ) { alert ("Please enter Numeric Value "); ... }
that will check whether the field contains any non-numeric characters, but it won't check for empty field, but this will:
Code:
if (!(/^\d+$/.test(fn)) ) { alert ("Please enter Numeric Value ");  }
Do you want to allow decimals, example 12.75?
