I have a form with input fields

the user inputs a name

i want to validate that this name doesnt contain any numeric values..

i want it to be purely letters

how is that?

Isnumeric only checks for if all the input is numeric not eahc character

HELP

Use a regular expression like this:

Code:

function validate(oTextbox)
{
    if ( /[^a-zA-Z]/.test(oTextbox.value) )
    {
         alert("failed validation");
    }
}

BTW that's client-side js. I can give you the corresponding code for server-side VBS if you want it.

No Problem, try this:

Code:

Dim re
Set re = New RegExp
re.Pattern = "[^a-zA-Z]"
If re.Test( Request.Form("input name") ) Then
    ' failed validation
End If
