ASP.NET 2.0中实现弹窗报警提示

ASP.NET 2.0中实现弹窗报警提示(3) 之后是写script了

 <script type="text/javascript">
            var numberOfEmails_original= 0;
           
            var app = Sys.Application;
            app.add_init(applicationInitHandler);
           
            function applicationInitHandler(sender, args) {
                InboxService.GetLatestNumberOfEmails(OnCurrentNumberOfEmailsReady);
      }

首先，默认的当然是0封邮件了，有变量来存放当前邮件数量，
之后是在ajax中的初始化事件中调用webserice的方法了，并且回调OnCurrentNumberOfEmailsReady方法，

      function OnCurrentNumberOfEmailsReady(result, userContext, methodName) {
                numberOfEmails_original= result;
                // Start Checking
                StartChecking();
            }

OnCurrentNumberOfEmailsReady方法将WEBSERVICE调用的结果（当前状态下有多少封信RESULT）返回给变量，然后调用sartchecking()方法

      function StartChecking() {
          InboxService.GetLatestNumberOfEmails(OnLastestNumberOfEmailsReady);
      }

startchecking方法，继续回调OnLastestNumberOfEmailsReady方法

            function OnLastestNumberOfEmailsReady(result, userContext, methodName) {
