话不多说,请看代码:

  <script type="text/javascript">
$(document).ready(function () {
$("#UserAccount").focus();
//记住用户名和密码
$('#remebers').click(function () {
if ($("#UserAccount").val() == "") {
alert("用户名不能为空!");
}
if($("#UserPassword").val() == "")
{
alert("密码不能为空!");
}
else {
if ($('#remebers').attr("checked")) {
setCookie("uname", $("#UserAccount").val(), 60);
setCookie("upwd", $("#UserPassword").val(), 60);
}
else {
delCookie("uname");
delCookie("upwd");
}
}
});
if (getCookie("uname") != null)
{
$('#remebers').attr("checked", "checked");
$('#UserAccount').val(getCookie("uname"));
$('#UserPassword').val(getCookie("upwd"));
}
})
//写cookies
function setCookie(name, value) {
var Days = 30;
var exp = new Date();
exp.setTime(exp.getTime() + Days * 24 * 60 * 60 * 1000);
document.cookie = name + "=" + escape(value) + ";expires=" + exp.toGMTString();
}
//读取cookies
function getCookie(name) {
var arr, reg = new RegExp("(^| )" + name + "=([^;]*)(;|$)");
if (arr = document.cookie.match(reg)) return unescape(arr[2]);
else return null;
}
//删除cookies
function delCookie(name) {
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval = getCookie(name);
if (cval != null) document.cookie = name + "=" + cval + ";expires=" + exp.toGMTString();
}
</script>
  <div class="main">
