eval解析json

后台向前端返回jsonresult，除了返回成功或者失败，有时候需要带上数据。

{"enterprise":{"address":"xxxxx路681号","bank_account":"","bank_name":"","contacter1":"李会计","contacter2":"",

"gzzt":"","id":0,"name":"xxxxxxx器材经营部","openid":"","qxgzsj":"","subscribe_time":"",

"taxno":"xxxxxxx7906270024","taxoffice":"其他","tel1":"xxxx371750","tel2":""}}

通过eval解析后的结果:

var enterprise = eval('(' + result.message + ')');

然后利用for循环把具体值取出:

var name=null;var taxno=null;var taxoffice=null;var address=null;var bank_name=null;var bank_account=null;var contacter1=null;var tel1=null;for(i in enterprise ){name=enterprise[i].name; taxno=enterprise[i].taxno;taxoffice=enterprise[i].taxoffice;address=enterprise[i].address;bank_name=enterprise[i].bank_name;bank_account=enterprise[i].bank_account;contacter1=enterprise[i].contacter1;tel1=enterprise[i].tel1;}

一个对象的List,转换为json，用JSONArray。

JSONArray result = JSONArray.fromObject(billdelList);

后台传前端：

request.setAttribute("billdelList", result.toString());

页面之间传递：

 window.location.href='<%=basePath%>pages/mobile/ddlb.jsp?list='+'${billdelList}'+'&main='+'${billmain1}';

前端传后台：

 window.location.href='<%=basePath%>kaiPiao.action?m=createXML&list='+list+'&main='+main；

要是取JSONArray里的内容，则要先toArray生成数组，利用for循环，取出List里的每个Object,将object转为jsonobject,获取字段值

    String good= request.getParameter("list"); //商品     System.out.println(good);    JSONArray goodArray=JSONArray.fromObject(good);    Object[] goodObj= goodArray.toArray();    //商品种类数量    int count=goodObj.length;    //FPXMXX 共计    int FPXMXXSL=0;    StringBuilder dataString=new StringBuilder();    for(int i=0;i<count;i++){    JSONObject goods=JSONObject.fromObject(goodObj[i]);
