Uppercase Form Function

Posted on 2002-05-28
Last Modified: 2008-03-04
I am working in ASP with VBScript. I have a form which includes a licence plate field as such:

Licence Plate:
<input type="text" name="BlackLP" size="40"><br>
<input type="submit" value="SUBMIT" id="submit1" name="submit1" onClick="return validate()">

The customer gave me this snippet of code to have licence plate numbers revert to capitols as we

type them in. Here is his message and code:

Can you trap the keystrokes so that you can only enter uppercase letters and numbers for the LP.  

Here is the snippet of code we use:
Private Sub txtLP_KeyPress(KeyAscii As Integer)
    Dim c$
    Dim n%
    If KeyAscii <> 8 Then    ' backspace
        n = 0
        If Len(txtLP) <= 12 Then
            c = Chr$(KeyAscii)
            c = UCase(c)
            If c < "A" Or c > "Z" Then
                If IsNumeric(c) Then
                    n = Asc(c)
                End If
                n = Asc(c)
            End If
        End If
        KeyAscii = n
    End If
End Sub

I do not know how to adapt it to the form in ASP and call it up. Can anyone help me?

Thank you

what browser's do you need to support? using styles is the easiest way.

<input type="text" name="BlackLP" size="40" style="text-transform:uppercase">

or another way wud be to let the user enter in any case, but store in upper case by using ucase()

I already tried ucase(), but he wants the keystrokes trapped and put in uppercase as you type. (style make kestrokes uppercase in some browsers). The code also keeps out symbol keys. He would like this used or modified if possible.

I renamed the function --> Function txtLP_KeyPress(KeyAscii)

I tried --> onkeypress="txtLP_KeyPress(KeyAscii)" but get errors, KeyAscii is undefined.

I put in BlackLP in both places, get error --> Object expected

I think using onkeypress is close, just not quite set up right.

Again, is there a way to call this function? Am i declaring the function wrong at the top? (Function txtLP_KeyPress(KeyAscii) OR Function txtLP_KeyPress(BlackLP)

thank you
