Jquery 实现 “下次自动登录” 记住用户名密码功能
Jquery将用户名密码存储到cookie中
需要导入jquery.js和jquery.cookie.js
<html>
<head>
<title>test cookie</title>
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script src="Scripts/jquery.cookie.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
if ($.cookie("rmbUser") == "true") {
$("#ck_rmbUser").attr("checked", true);
$("#txt_username").val($.cookie("username"));
$("#txt_password").val($.cookie("password"));
}
});
//记住用户名密码
function Save() {
if ($("#ck_rmbUser").attr("checked")) {
var str_username = $("#txt_username").val();
var str_password = $("#txt_password").val();
$.cookie("rmbUser", "true", { expires: 7 }); //存储一个带7天期限的cookie
$.cookie("username", str_username, { expires: 7 });
$.cookie("password", str_password, { expires: 7 });
}
else {
$.cookie("rmbUser", "false", { expire: -1 });
$.cookie("username", "", { expires: -1 });
$.cookie("password", "", { expires: -1 });
}
};
</script>
</head>
<body>
<div>
用户名：<input type="text" id="txt_username"/><br />
密码：<input type="text" id="txt_password"/><br />
<input type="checkbox" id="ck_rmbUser"/>记住用户名和密码<br />
