window.localStorage保存的是键值对key/value
【设置值】
var cache=window.localStorage;
cache.setItem("test","123456");
window.localStorage.setItem("test","123456");【获取值】
var cache=window.localStorage;
cache.getItem("test");
window.localStorage.getItem("test");
【字符串转json数组对象】
1、字符串转json对象
1）var json = eval('(' + '[{"key":"value"},{"key":"value"}]'+ ')');
2）JSON.parse('[{"key":"value"},{"key":"value"}]');
2、json对象转字符串
JSON.stringify([{"key":"value"},{"key":"value"}]);
