js syntax error within Visual Studio 2012

Hello,

I'm getting a syntax error in the bold items below in my .js file.  I'm working within Visual Studio 2012.

function SetPageTimes()
{
    msecPageLoad = new Date().getTime();

    msecTimeOut = (<%=Session.Timeout%> * 60 * 1000); // The page will time out depends on the value of Session.Timeout parameter in web.config

    msecWarning = (<%=Session.Timeout%> * .95 * 60 * 1000); // The warning message will pop up after passing 95% of the total time
}

Let me know if you need additional information.
I appreciate any help.  Thanks.

what about :

function SetPageTimes() 
{
    msecPageLoad = new Date().getTime();
    var x = "<%=Session.Timeout %>";
    msecTimeOut = x * 60 * 1000; // The page will time out depends on the value of Session.Timeout parameter in web.config
    msecWarning = x * .95 * 60 * 1000; // The warning message will pop up after passing 95% of the total time
}

If this is a seperate js file then it does not have access to the ASP variables.

Store the Session.Timeout in an hidden field with an ID and then reference the input in your js file

document.getElementById("session_timeout_input_id").value

Open in new window

msecTimeOut = (parseInt(document.getElementById("session_timeout_input_id").value) * 60 * 1000); 

Open in new window

Otherwise add some js to the actual .net page and store the timeout in a global var that you can reference in the external file.

Though since the timeout never really changes why not just hardcode the value?
