EXTJS 实现session 的另一种方法

JS：

1. function showResult(btn){
   
2.         //Session过期，返回登录页面
   
3.         top.location.href='login.html';
   
4. };
   
5. check_login=function(){
   
6. Ext.Ajax.request({
   
7.                     url: './inc/session.asp',
   
8.                     success: function(response, options) {
   
9.                       var responseArray = Ext.util.JSON.decode(response.responseText);                                            
   
10.                             if(responseArray.success==false){
    
11.                                                                 Ext.MessageBox.show({
    
12.                                                                         title: '会话超时',
    
13.                                                                         msg: '您的会话已由于超时而过期，请您重新登录！',
    
14.                                                                         buttons: Ext.MessageBox.OK,
    
15.                                                                         fn: showResult,
    
16.                                                                         icon: Ext.MessageBox.WARNING
    
17.                                                                 });
    
18.                                                         }
    
19.                     }
    
20.             });
    
21. };
    
22. check_login();
    

复制代码

ASP:

1. <% response.ContentType="text/html;charset=utf-8" %>
   
2. <%
   
3. IF session("code")<>"" Then
   
4.         Response.Write "{success: true,session:'"&session("code")&"'}"
   
5. Else
   
6.         Response.Write "{success: false,session:'login.html'}"
   
7. End IF
   
8. %>

我想不用我再解释什么了吧，将JS代码引用到共用JS部分中就可以了。
