localStorage 储存与读取

window.onload=function(){
    /**
     *其实也没那么难，
     *localStorage.setItem(json)  向本地储存值
     *window.localStorage["键"]   得到本储存的值
    */
    var setl = document.getElementById("setl");
    setl.onclick=function(){
        var name = document.getElementById(‘name‘).value;
        localStorage.setItem("name",name);
        var password = document.getElementById("password").value;
        localStorage.setItem("password",password);
    }
    var redl = document.getElementById("redl");
    redl.onclick=function(){
        var storage = window.localStorage;

        var password = storage["password"];
        if(storage["password"]== undefined && storage["name"]==undefined){
