如何访问global.asax中的javascript变量？

Question

I have a javascript variable in a page default.aspx

var name="user1"

window.location="test.aspx"

this page will submit to test.aspx and in global.asax while firing Application_BeginRequest event ,i need to access the variable "name". i need to do this without cookies. Anyone can help me on this?

Answer 1

var name="user1" is a javascript variable that you could access inside Application_BeginRequest from the Request object assuming you have passed it to the test.aspx page when redirecting:

var name = "user1";
window.location.href = 'test.aspx?name=' + encodeURIComponent(name);

and then:

protected void Application_BeginRequest(object sender, EventArgs e)
{
    string name = HttpContext.Current.Request["name"];
    if (!string.IsNullOrEmpty(name))
    {
        // the name variable was present in the request => do something with it
    }
}

Answer 2

If by "submit" you mean perform a POST or GET request then you'll need to pass name as a url-encoded string to the server as a form POST or as a querystring parameter in a GET request.

Then, in the Application_BeginRequest access the Request from the Current HttpContext
