Please see below code:
In Javascript

JavaScript

function CallAJAX()
{
	var xhr = new XMLHttpRequest();
	var parameters = "name=XXX"+"& Age=20";
	xhr.open("POST","page_2.aspx",true);

	xhr.send(parameters);
	if (xhr.readyState==4) // 4 = "Response loaded"
	{
		if (xhr.status==200) // 200 = Response Error Free  
		{             
		  alert(xhr.responseText);
		}
		else
		{
			alert("Problem retrieving XML data");
		}
	}
}

In Code-Behind(Page2.apsx)

C#

protected void Page_Load(object sender, EventArgs e)
{
        Response.Cache.SetCacheability(HttpCacheability.NoCache);     
        if (Request.Form["name"] != null)
        {
            string temp = Request.Form["name"];
            Response.Write(DateTime.Now.ToShortTimeString());
            Response.End();
        }
}
