即時工作域檢查腳本它工作正常,當我在keyup上調用ajax,但默認情況下下拉有.com如果用戶選擇一個已經採取的域,我怎麼能得到這個腳本做另一個檢查時,用戶從.com切換到.net或.org?用下拉菜單調用jquery ajax()?

事情是這樣的:

$('select[name="tld"]').change(function() { 
    //your ajax code 
}); 

這當然會複製你的代碼,所以我會建議它包裹裏面的函數。

刪除「」 TLD左右,所以它應該是$(「選擇[名稱= TLD]」)... – Manie 2010-08-23 06:41:23

感謝重放,我裹成一個功能和它的作品,直到第二個請求

例如默認.COM我改變到.NET它不工作和我改變.org等,然後它開始上班。還我登錄MySQL的所有檢查和創建重複條目

您需要使用活。更多關於這裏http://api.jquery.com/live/ 這樣的事情:$(selecter).live('change',function(){...}); 或者第二個選項是類似的,但你必須自己綁定事件。 – realshadow 2010-08-23 07:53:32
