calling a javascript function in from VBscript

jakyra · September 18th, 2003, 03:44 PM

So I've got this validation code that does a complex enough function that I don't want to convert it to VBscript.

But now I need to do validation on an ASP page.

so I've got this fucntion in javascript:
IsISBN(isbn) {
some validation stuff with a boolean return
}

and from my page I want to do something like

Code:

<%
  myArray(3,1)
  for i = 0 to 3
    fieldname = "isbn" & i
    myArray(i, 0) = request.form(myField)
    myArray(i,1) = IsISBN (myArray(i,0))
  next 
  ...
%>

is this even remotely possible or am I stuck converting my validation function?

Thanks

I would just convert it.... why wouldn't you?

Anyway, after looking at how ISBN Validation works, I did this:-

Code:

Function CheckISBN(x)
	Length = Len(x)
	If NOT (Length > 10 Or Length = 0) Then 
		intValue = 0
		For Counter = 10 To 1 Step -1
			If Counter <= Length Then
        		intValue = intValue + (Counter * Mid(x, ((-1 * Counter) + Length + 1), 1))
	    	End If
		Next
		CheckISBN = (intValue Mod 11 = 0)

	Else
    		CheckISBN = False
	End If
End Function

I admit, I have not accounted for the X's that are allowed in ISBN numbers, and the function will fall-over if it comes across an X in an ISBN.... but hey, I didn't want to strip the entire challenge away from you!!

I've started you off, so just fill in the last bits!!

'cause I'm lazy.

I was just wondering if there was an easy way to save myself some time.

Ahh well, on to the conversion board.

Thanks!
