GWT-EXT中的confirm框的点击确定“是/否”的监听

代码如下： 

1. MessageBox.confirm("Confirm", "Are you sure you want to do that?",   
2.                             new MessageBox.ConfirmCallback() {   
3.                                 public void execute(String btnID) {     
4.                                     if(btnID.equals("yes")){
5.                                         /*确定的操作*/
6.                                                 /*要执行的代码*/
7.                                     }
8.                                         if(btnID.equals("no")){
9.                                         /*否定的操作*/
10.                                                /*要执行的代码*/
11.                                     }
13.                                 }   
14.                             }); 

 

这样就能通过是、否来执行不同的操作
