JavaScript

//结合JSON.stringify使用更强大
var person = {'name': 'rainman', 'age': 24};
localStorage.setItem("me", JSON.stringify(person));
console.log(JSON.parse(localStorage.getItem('me')).name);	// 'rainman'

/**
 * JSON.stringify，将JSON数据转化为字符串
 *     JSON.stringify({'name': 'fred', 'age': 24});   // '{"name":"fred","age":24}'
 *     JSON.stringify(['a', 'b', 'c']);               // '["a","b","c"]'
 * JSON.parse，反解JSON.stringify
 *     JSON.parse('["a","b","c"]')                    // ["a","b","c"]
