Multiple selections in SELECT in ASP

**noone** · Aug 1st, 2000, 04:55 PM

Hi, I feel kind of stupid for asking this but I need to know how to check what was selected on a multiple listbox.
eg:
<SELECT id=select1 multiple name=Employees size=5>
some options here
</select>

How would I use ASP code to find out what was selected. And if anyone could point me to a page about checking different form elements by ASP it would be very appreciated.

Well I figured it out if anyone else was wondering:

Code:

Dim EmployeeCount
EmployeeCount = Request.Form("Employees").Count
dim i
For i = 1 to EmployeeCount
	Response.Write(Request.Form("Employees").Item(i))
Next

The code you have will work if you have a submit button, but if you have a regular button then you can do it using a client side scripting:

Code:

<HTML>
<HEAD>

<SCRIPT LANGUAGE=vbscript>

Sub GetCount() 
	Dim colOptions
	Dim i
	Dim strValues
	
	Set colOptions = frmMyForm.lstList.Options

	For i = 0 To colOptions.length - 1
		If colOptions(i).Selected Then
			strValues = strValues &  colOptions(i).Value & vbCrLf
		End If
	Next
	window.alert strValues
	

End Sub

</SCRIPT>
</HEAD>
<BODY>

<P> </P>


<FORM name=frmMyForm action=Serge.asp>

<SELECT name=lstList multiple>
	<%For i = 1 To 10%>
		<OPTION Value=<%="Item" & CStr(i)%>><%="Item" & CStr(i)%></OPTION>
	<%Next%>
</SELECT>

<INPUT type="button" value="Count Selected Items" name=cmdCount onclick="GetCount">
</FORM>

</BODY>
</HTML>
