也可直接寫在頁面腳本里：

復制代碼代碼如下:

 
<script> 
function pageLoad() 
{ 
var manager = Sys.WebForms.PageRequestManager.getInstance(); 
manager.add_beginRequest(OnBeginRequest); 
manager.add_endRequest(OnEndRequest) 
} 
var lcPostbackElementID; 
function OnBeginRequest(sender, args) 
{ 
lcPostbackElementID = args.get_postBackElement().id.toLowerCase(); 
if (lcPostbackElementID === 'btnadwords') 
{ 
$get('btnAdWords').disabled = true; 
$get('btnAdWords').value='正在提交...'; 
} 
} 
function OnEndRequest(sender, args) 
{ 
if (lcPostbackElementID === \"btnadwords\") 
{ 
$get('btnAdWords').disabled = false; 
$get('btnAdWords').value='確定'; 
} 
} 
< /script>
