Turn If... Then... Else... to Case statement

Hello all

I trying to create a menu for a site.

I've picked up this script to show and/or hide layers. It uses an If... Then... Else statement which in the example is fine. My menu will have up to eight entries so I think a Case statement may be the way to go.

My problem is I don't know anything about using Case in this instance so I'm looking for some help.

Here's the code.
<%
'declare 1 for each layer
Dim vis1, vis2

If request("show") = 1 Then
   vis1 = "visible"
   vis2 = "hidden"
Else
   vis1 = "hidden"
   vis2 = "visable"
End IF

%>

<div id="hide" style="visibility:<%=vis2%>;">this is my visable div</div>
<div id="test" style="visibility:<%=vis1%>;"> this is my hidden div</div>

<a href="testdiv.asp?show=1">show hidden layer</a>
<a href="testdiv.asp?show=2">show other layer</a>

Open in new window


Thanks in advance for the help.

Please see this article explaining IF / ELSE as well as SELECT CASE statements:

http://www.w3schools.com/vbscript/vbscript_conditionals.asp


Sample:
Select Case request("show")
  Case 1
    vis1 = "visible"
    vis2 = "hidden"
  Case 2
    vis1 = "hidden"
    vis2 = "visible"
  Case else
    vis1 = "visible"
    vis2 = "hidden"
End Select

case when request("show") = 1 Then  vis1 = "visible"
        when request("show") = 1 Then  vis2 = "hidden"
        when request("show") <> 1 Then  vis1 = "hidden"
        when request("show") <> 1 Then  vis2 = "visable"
end

Thanks for the replies both.

I take that the Dim statement remains the same. ie:

Dim vis1, vis2

the code above is wrong, here is the correct code:
select case Request("show")
    case 1:
          vis1 = "visible"
          vis2  "hidden:
    case 2:
          vis1 = "hidden"
          vis2 = "visible"
    case "n/a":
          vis1 = ""
          vis2 = ""
    case else:
          '-- do whatever 
end select

this is just an example obviously, you'll need to fit it to your needs. the "case else" statement is the same as the else statement in a nested if/else block, it is not required.
