json异步转换

在js中，根据js所获得的属性，如果只是靠简单的转换为java属性是异常艰辛的。这里是我在实践中，通过id获取很多字段，相应的填在tr下。具体代码如下：

 <script type="text/javascript">

//动态增加tr
   function save(a,b,c,d,e,s){
      addTr(a,b,c,d,e,s);
   }

//根据id查出其他字段
   function getcheck(){
    var x=document.getElementsByName("row_sel");
    var strs=[]; 
    for(var k=0;k<x.length;k++){
     if(x[k].checked){
      var s=x[k].value+"";
      $.ajax({
       type: "post", 
       url : "<%=path%>/prolm/directorWorkshops/doexpduibi.jsp",
       dataType:‘json‘,
       async: false,    //下面的window.close();方法在此全部结束后调用，叫 回调
       data: ‘id=‘+s, 
       success: function(json){
       if(json.flag=="error")
       {
       alert("导出错误！");
       return;
       }    
       var intest=json.flag;    
      strs=intest.split(",");       
      save(strs[1],strs[2],strs[3],strs[4],strs[5],strs[0]);
      flags="1";
    
       } ,
       error:function()
       {
       alert("导出出错！");
       return;
       }
       });       
     }
    }
  window.close();
    }
  
   </script>

下面为doexpduibi.jsp页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@page import="com.hshz.xdb.Access"%>

<% response.setHeader("Pragma","No-cache");
 response.setHeader("Cache-Control","no-cache");
 response.setDateHeader("Expires", 0);
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
String type=request.getParameter("id");
String sql="select * from T_APP_PROJECTAPPLY where id=‘"+type+"‘ ";

 Map m=Access.getSingleMap(sql,null);

StringBuffer sb=new StringBuffer("");

sb.append(m.get("id")+","+n.get("primaydutydept")+","+m.get("projectname")+","+m.get("onelevelcompetentdept")+","+ m.get("projectmanager")+","+m.get("financemanager")); out.print("{\"flag\":\""+sb.toString()+"\"}");
