update global.asax variable from javascript

[Munteanu Ciprian]

Hi! I have a global variable which is initialized in Global.asax (in the Session_start event). Now I want using Javascript to update this variable and I don't know how to do that. Why I have to do that? Because I used javascript to create a small timer which, at every 10 minutes I want to increase the variable by 1. Can anyone help me please?

Hi Munteanu, Create a page or a web service to increase your value. Use AJAX request to call the page/web service. For the web service you can use generated proxy javascript classes to call it. For the page you can use for example jquery to call it. http://docs.jquery.com/Ajax

Hi, just create ASP.NET page. On page_load increment your value.

public partial class my_page : System.Web.UI.Page {

    protected void Page\_Load(object sender, EventArgs e) {
        // increment your value
    }
}

from the JavaScript call your page:

$.get('my_page.aspx');

Are you sure this is the correct way to call the page in javascript: "$.get('my_page.aspx');"? I've tried and it's not working...

[Petr Pechovic]

yes :) you have to download the jQuery library and add the script reference to it. It's just one file. Here: jQuery mini[^]

And how do I add the script reference and where should I put the file?
