javascript function together with asp.net

Question

Hi, I am trying to create a link, which will onclick change a session variable like this

<a href="/Index" onclick="<% HttpContext.Current.Session["location"] = location;%>" >
    <%=location%>
</a>

However, during processing the page the session changes on its own during generating each anchor element (with this onclick attribute). So I would like to create a javascript function like

<script type="text/javascript" >
    function session(location) {
        HttpContext.Current.Session["location"] = location;
    }
</script>

Unfortunatelly, I don't know enough, so this doesn't seem working.. Any ideas? Thanks in advance

Answer 1

Session is an ASP.NET server object that is not accessible from the client through JavaScript directly (Session may be stored as a cookie on the client, but then even then, it is not designed to be accessed from the client-side directly). You could handle what you want to do in a number of ways -

1. Store a value in a hidden input when a link is clicked and then read that value server-side and store in Session.

2. Store in Session on postback in a Click event handler for the anchor. You may want to use the asp:HtmlAnchor control for this and set up an event handler for the OnServerClick event
