WebRequestManager对象的使用

WebRequestManager可以喝WebRequest对象一起使用。

WebRequestManager对象的add_completedRequest方法，可以用来处理所有WebRequest对象的请求程序。

Time.aspx

<%@ Page Language="C#" %>

<script runat="server">

    protected override void OnLoad(EventArgs e)

    {

        base.OnLoad(e);

        Response.Write(DateTime.Now.ToUniversalTime());

    }

</script>

GlobalCompleted.aspx

<%@ Page Language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title>Networking</title>

    <script type="text/javascript">

        function pageLoad() {

            Sys.Net.WebRequestManager.add_completedRequest(completedHandler);

            var webRequest = new Sys.Net.WebRequest();

            webRequest.set_url("Time.aspx");

            var webRequest2 = new Sys.Net.WebRequest();

            webRequest2.set_url('TimedSleep.aspx');

            Sys.Net.WebRequestManager.executeRequest(webRequest2);

            Sys.Net.WebRequestManager.executeRequest(webRequest);

        }

        function completedHandler(executor) {

            if (executor.get_responseAvailable()) {

                $get('placeholder').innerHTML += "<br />" +

                    executor.get_webRequest().get_url() +

                    " returned " +

                    executor.get_responseData();

            }

        }

    </script>

</head>
