HTML5本地存储localStorage sessionStorage

HTML5新特性，用于本地存储，

localStorage：不删除会一直存在斯基

sessionStorage：浏览器关掉，就跪了

/*** H5:数据存储方式，可以携带用户信息id* * 注意：* 此方法存文件为key,value方式* 注意key不要重复* *本地存储使用方法：* storage.setItem("name", "Rick"); //调用setItem方法，存储数据* alert(storage.getItem("name")); //调用getItem方法，弹框显示 name 为 Rick* storage.removeItem("name"); //调用removeItem方法，移除数据* alert(storage.getItem("name")); //调用getItem方法，弹框显示 name 为 null* */var storage = null;if (window.localStorage) { //判断浏览器是否支持localStoragestorage = window.localStorage;}function StrIsNotEmpt(str) {let strflag = true;if (str == "" || str == undefined || str == null) {strflag = false;}return strflag;}// var sessionStorage = null;// if(window.sessionStorage) {// sessionStorage = window.sessionStorage;// }

对象测试：

// localStorage.setItem("name", "123");// var name = localStorage.getItem("name");// console.log(name);// localStorage.removeItem("name");// localStorage.clear(); //清空// var userData = {// name: "三哥",// age: 18// }// localStorage.setItem("userData", JSON.stringify(userData));// var userData = JSON.parse(localStorage.getItem("userData"));// userData.name = "123";// localStorage.setItem("userData", JSON.stringify(userData)); //数据更新// console.log(userData);// console.log(localStorage.getItem("userData"));// var people = new Object();// people.name = "张三";// people.age = 10;// people.saly = 10000;// console.log("people:" + JSON.stringify(people));
