OnChange just won't work

[Kalor]

Hi all,

I want to populate a text box based on the selected value in a SELECT list (combo box). I'm at my wits end trying to get OnChange to do ANYTHING. I've found some examples on the net but if I use the code it still does zippo.

Here's my code:
------------------------------------------------------
<%
Sub FindClassDesc()
'On Error Resume Next
'frm.txtTEST = &quot;Zippedydoodah&quot;
msgbox(&quot;hello&quot
End Sub
%>

(lots of html)

<select size=&quot;1&quot; name=&quot;cboUSERCLASS&quot; language=&quot;VBScript&quot; OnChange=&quot;FindClassDesc()&quot;>
<%
'--VBScript to fill combo box from a database table, which works fine
%>
</SELECT>
-------------------------------------------------

advaTHANKSnce,

Steven.

you can't reference a sub via server side with client side events
you would actually have to have a submission or some event that would run the code seperatly via a seperate file (.asp) or a form submit.
Another thing you can't do is have a msgbox server side. Sorry to burst your bubble man, but that's server life.

take a different approach like submiting the form on change via javascript and run the server side code to populate a new select on no error. You'll need to response.write the error to the page.
Not everything you type is understanding to others! Think about that before getting upset with a wrong answer to your question.

If I understand your dilema, You want to fill a text box with the selected option from a dropdown list. If this is what you wish to accomplish this should do it for you...


<script language=&quot;vbscript&quot;>
Sub FindClassDesc()
'fill it with value selected
document.frm.txtTest.value=document.all.cboUserClass.value 'fill it with the text selecte
document.frm.txtTest.value=document.all.cboUserClass.options(document.all.cboUserClass.selectedIndex).text
End Sub
</script>

--other stuff--
<select size=&quot;1&quot; name=&quot;cboUSERCLASS&quot; language=&quot;VBScript&quot; OnChange=&quot;FindClassDesc()&quot;>

good luck

Thanks. That would do it, but what I want is to populate the text box with data looked up in a table, based on the combo box selection (eg the user selects &quot;WA&quot; and the 'State Description' box is populated with 'Western Australia' (or Washington ).

As onpnt picked up, I think I'm getting client side and server side a little confused. I've developed a workaround and lowered the user's expectations a bit.
