之后是寫script了

}

首先，默認的當然是0封郵件了，有變量來存放當前郵件數量，之后是在ajax中的初始化事件中調用webserice的方法了，并且回調OnCurrentNumberOfEmailsReady方法，

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

OnCurrentNumberOfEmailsReady方法將WEBSERVICE調用的結果（當前狀態下有多少封信RESULT）返回給變量，然后調用sartchecking()方法

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

startchecking方法，繼續回調OnLastestNumberOfEmailsReady方法

    function OnLastestNumberOfEmailsReady(result, userContext, methodName) {
                var numberOfEmails_new= result;
                if (numberOfEmails_new > numberOfEmails_original) {
                    ShowPopup();
                    $get("modalBody").innerHTML= numberOfEmails_new - numberOfEmails_original;

                    // Update the count here

                     numberOfEmails_original= numberOfEmails_new;
                }
                // Start checking again
                window.setTimeout(StartChecking, 10000);
            }

這個方法，用當前郵件數-原來郵件數，就得出新增了多少封郵件了，再將結果賦值給顯示區域的modalbody，并且記得把當前郵件數量的,變量更新哦（numberOfEmails_original= numberOfEmails_new;）

然后再用setimeout來設置每隔10000毫秒檢查一次了

          function ShowPopup() {
                $get("UpdateProgress1").style.visibility= "visible";
                $get("UpdateProgress1").style.display= "block";
            }
            function HidePopup() {
                $get("UpdateProgress1").style.visibility= "hidden";

                $get("UpdateProgress1").style.display= "none";
            }
        </script>
