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);
