html5两种存储方式

// sessionStorage存储周期为关闭页面存储就自动清除
function send(){
var username = $("#name").val();
var pass = $("#password").val();
sessionStorage.setItem("k_username",username);
sessionStorage.setItem("k_pwd",pass);
alert("存储成功");
}
function send2(){
alert(sessionStorage.getItem("k_username"));
alert(sessionStorage.getItem("k_pwd"));
}

------分割线-------

//localStorage
function send3(){
var username = $("#name").val();
var pass = $("#password").val();
localStorage.setItem("k_username",username);
localStorage.setItem("k_pass",pass);
alert("local存储成功");
}

function send4(){
alert(localStorage.getItem("k_username"));
alert(localStorage.getItem("k_pass"));

}
//清除存储
function send5(){
//删除单条
localStorage.removeItem("k_username");
localStorage.removeItem("k_pass");
//删除全部
// localStorage.clear();
}
