check for blank fields in a form

[chqdzn]

I'm a newbie to vbscript. I need to check my form for blank txtbox fields. I wrote a function using select case to check for correct quantity and type of data, so that once this info is correct, the cursor moves to the next txtbox and so on. however, i need to make sure my users enter data in the first place! How do i do this?

thanks in advance!

Here's a snippet. How do I check to make sure the boxes are not blank?

thanks in advance!


<script language="vbscript">
Function checkLength
Select Case n
Case 3
if Len(document.Form1("txt1box").value) >= 3 then
if IsNumeric(document.Form1("rrtxt3box").value) Then
document.Form1("txt2box").focus()
Else
alert("Characters must be numeric")
'end if
end if
end if
end select
end Function
</script>

If document.Form1("txt1box").value = "" Then
'Handle it here
End If

Thanks, TomThumbKP--
I tried that vbs statement at the start of this whole process, but it didn't work. When I use that statement, I lose the "jump-to-next-txtbox" (j2ntb) functionality, and the form still submits.

Where I'm finding the trouble is that my form is using a server-side (ss) submit control. I writing the app in asp.net because other controls on the form need to be handled by the server. I using vbscript for client-side (cs) scripting because there is no setfocus or focus control/method in asp.net yet to handle my j2ntb function.

Is there a vbscript/js written to work with an asp.net control, in this case, the submit button?

Any suggestions/leads are greatly appreciated!

Thanks in advance!!
