Question

I have this code:

<a href="index.asp" onclick="<%Session("example") = True%>">LINK</a>

The problem is that this result in the session example will be true when loading this page and not when clicking on the link.

How can I solve this?

Answer 1

All the server code in the page runs on the server before the page is sent to the browser. What you end up with in the browser is just:

onclick=""

If you want to run server code when an event happens in the browser, you have to make another request to the server. You can either make a postback of the page and send some information back to the server (in querystring/formdata/cookie), or use AJAX to request a different page that contains the server code that you want to run.

Edit:

To use a querystring, make a reload of the same page and add for example ?ex=1 to the URL. In the server code you can check for this and set the session:

If Request.QueryString("ex") = "1" Then
  Session("example") = True
End If
