localstorage-前端存储

(function (win,doc) {    var local_storage = {        //创建localstorage @param argument  json || string        items: function (argument) {            if (typeof argument == ‘object‘) { //创建                for (var i in argument) {                    win.localStorage.setItem(i, argument[i]);                }            } else if (typeof argument == ‘string‘) {  //获取                return win.localStorage.getItem(argument);            } else {                return console.error(‘参数只能是json或者string‘);            }        },        //删除localstorage  @param val  string || null        rmitems: function (val) {            if (val) {                win.localStorage.removeItem(val);            } else {                var json = window.localStorage;                for (var i in json) {                    win.localStorage.removeItem(i);                }            }        }    }    win.local_storage =local_storage ;

})(window,document);用个js来装载，要用的时候直接调用还是很方便的，用json格式来装载，直接在另一个js里调用：如 local_storage .items({name:‘哈哈‘,age:12});就可以直接用把长的代码简单化
