Answer 1

• unescape('\u4ec5\u552e12.8\u5143\uff01\u4ef7\u503c634\u5143\u7684E\u5149\u51b0\u70b9\u8131\u6bdb\/\u70b9\u7a74\u51cf\u80a5\u5851\u5f622\u90091\u5957\u9910\uff0c\u7537\u5973\u4e0d\u9650\uff0c\u63d0\u4f9b\u514d\u8d39WiFi\u3002\u8ba9\u7f8e\u4e3d\u7efd\u653e\uff0c\u8ba9\u9752\u6625\u6c38\u9a7b\uff01');
  

• 以下是几种js读出的json数据的方式：

  var json = {  contry:{ area:{ man:"12万",  women:"10万" } } };

• 方式一：使用eval解析  var obj = eval(json);  alert(obj.constructor);alert(obj.contry.area.women);   //

• 方式二：使用Funtion函数 

  var strJSON = "{name:'json name'}";//得到JSON  var obj = new Function("return" + strJSON)();//转换后的JSON对象     alert(obj.name);//json name      alert(obj.constructor);    

• 复杂一点的json数组数据的解析 var value1 = [{"c01":"1","c02":"2","c03":"3","c04":"4","c05":"5","c06":"6","c07":"7","c08":"8","c09":"9"}, {"c01":"2","c02":"4","c03":"5","c04":"2","c05":"8","c06":"11","c07":"21","c08":"1","c09":"12"}, {"c01":"5","c02":"1","c03":"4","c04":"11","c05":"9","c06":"8","c07":"1","c08":"8","c09":"2"}];   var obj1 = eval(value1);  alert(obj1[0].c01);  /

• 复杂一点的json的另一种形式

  var value2 = {"list":[ {"password":"1230","username":"coolcooldool"}, {"password":"thisis2","username":"okokok"}], "array":[{"password":"1230","username":"coolcooldool"},{"password":"thisis2","username":"okokok"}]};   var obj2 = eval(value2);  alert(obj2.list[0].password);
