jQuery代码:
<script src="js/jquery-1.3.1.js" type="text/javascript"></script> <!-- 引入引用jquery的库文件 -->
<script src="js/jquery.cookie.js" type="text/javascript"></script> <!-- 引入jQuery的cookie插件 -->
<script type="text/javascript">
//初始化页面时验证是否记住了密码
$(document).ready(function() {
if ($.cookie("rmbUser") == "true") {
$("#rmbUser").attr("checked", true);
$("#wsc-username").val($.cookie("userName"));
$("#wsc-password").val($.cookie("passWord"));
}
});
function saveUserInfo() {
if ($("#rmbUser").attr("checked") == true) {
var userName = $("#wsc-username").val();
var passWord = $("#wsc-password").val();
$.cookie("rmbUser", "true", { expires: 7 }); // 存储一个带7天期限的 cookie
$.cookie("userName", userName, { expires: 7 }); // 存储一个带7天期限的 cookie
$.cookie("passWord", passWord, { expires: 7 }); // 存储一个带7天期限的 cookie
}
else {
$.cookie("rmbUser", "false", { expires: -1 }); // 删除 cookie
$.cookie("userName", '', { expires: -1 });
$.cookie("passWord", '', { expires: -1 });
}
}
</script>
HTML代码:
<body>
<form action="" method="post">
<div class="form">
<div >
<label>用户名：</label>
<input maxlength="200" value="" name="u_username" class="log_Field" >
</div>
<div class="loginItem" >
<label>密 码：</label>
<input type="password" value="" maxlength="20" name="u_pwd" class="log_Field" >
</div>
<div class="loginRemember">
<input type="checkbox" checked="true" name="chkRememberUsername" class="checkbox" >
<label for="rmbUser">记住用户名</label>
<a href="#">忘记密码?</a>
</div>
<div class="loginItem loginButton" >
<input type="submit" value="登录" onclick="saveUserInfo()" class="button" >
</div>
</div><!--form div-->
</form>

下面是jquery.cookie.js用法
$.cookie('the_cookie'); // 获得cookie
$.cookie('the_cookie', 'the_value'); // 设置cookie
$.cookie('the_cookie', 'the_value', { expires: 7 }); //设置带时间的cookie
$.cookie('the_cookie', '', { expires: -1 }); // 删除
$.cookie('the_cookie', null); // 删除 cookie
$.cookie('the_cookie', 'the_value', {expires: 7, path: '/', domain: 'jquery.com', secure: true});//新建一个cookie 包括有效期 路径 域名等
