js处理json数据

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'}" ; //得到的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);
