良好的登录页面是系统的唯一入口，良心说，我是很难做出漂亮的登录界面，所以有点违背本文的标题，因为我不是一个美工。汗..!
第二讲我已经发布了源码,我们添加一个Account空控制器,虽然后台未实现，但是以后我们就要用到了。
添加index视图，以下代码
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<title>系统登录</title>
<script src="/Scripts/jquery.min.js" type="text/javascript"></script>
@Styles.Render("~/Content/themes/blue/css")
<link href="~/Content/Site.css" rel="stylesheet" />
<style type="text/css">
body
{
letter-spacing: 1px;
color: #444;
}
#LoginTb
{
font-size: 14px;
}
#LoginTb
{
font-size: 12px;
}
#LoginTb input
{
190px;
height: 24px;
line-height: 24px;
}
</style>
<script type="text/javascript">
$(function () {
$("#LoginSys").click(function () {
LoginSys();
});
$("#UserName").keydown(function (e) {
var curkey = e.which;
if (curkey == 13) {
LoginSys();
return false;
}
});
$("#Password").keydown(function (e) {
var curkey = e.which;
if (curkey == 13) {
LoginSys();
return false;
}
});
$("#ValidateCode").keydown(function (e) {
var curkey = e.which;
if (curkey == 13) {
LoginSys();
return false;
}
});
});
function LoginSys() {
$("#mes").html("");
$("#UserName").removeClass("input-validation-error");
$("#Password").removeClass("input-validation-error");
$("#ValidateCode").removeClass("input-validation-error");
if ($.trim($("#UserName").val()) == "") {
$("#UserName").addClass("input-validation-error").focus();
$("#mes").html("用户名不能为空！");
return;
}
if ($.trim($("#Password").val()) == "") {
$("#Password").addClass("input-validation-error").focus();
$("#mes").html("密码不能为空！");
return;
}
if ($.trim($("#ValidateCode").val()) == "") {
$("#ValidateCode").addClass("input-validation-error").focus();
$("#mes").html("验证码不能为空！");
return;
}
$("#Loading").show();
alert(1);
return false;
}
