JSON.parse()和JSON.stringify()

stringify()用于从一个对象解析出字符串；

var person = {name:"vanida","sex":"girl","age":25};

localStorage.setItem("person",JSON.stringify(person));

// localStorage.person="{"name":"vanida","sex":"girl","age":25}"

注意：JSON.stringify()中不要忘了“i”,stringify而不是stringfy！

parse用于从一个字符串中解析出json对象 可以用JSON.parse();

person = JSON.parse(localStorage.getItem("person"));

// {name: "vanida", sex: "girl", age: 25}
