WebRequestManager对象的使用

浏览数：29 / 时间：2015年06月09日

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#" %>

        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(); 
            }
        }
