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);
}
这个方法，用当前邮件数-原来邮件数，就得出新增了多少封邮件了，再将结果赋值给显示区域的modalbody，并且记得把当前邮件数量的,变量更新哦（numberOfEmails_original= numberOfEmails_new;）
然后再用setimeout来设置每隔10000毫秒检查一次了
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>
