JSON.stringify

JSON.stringify用法总结：

1.JSON.stringify(args)

var person = new Object();

person.name = "ligang";

person.sex = "男";

var json = JSON.stringify(person);

//alert(json);

//alert(person);

将对象转换为JSON字符串

2.JSON.stringify(arrays,function)

var person = new Array();

person["name"] = "litianyi";

person["age"] = 18;

person["sex"] = "男";

var json = JSON.string(person,changeUpper);

function changeUpper(key,value){

   return value.toString().toUpperCase();

}

alert(json);

3.JSON.stringify(arrays,secArrays);

var person = new Object();

person.name = "ligang";

person.sex = "男";

var person2 = new Array();

person2[0] = "age";

person2[1] = "sex";

person2[2] = "name";

var json = JSON.stringify(person,person2);

alert(json);

4.JSON.stringify(student,stu,10);

10:为缩进的最大值。。。
