EF采用DatabaseFirst的方式处理数据
新建一个LoginController
[HttpGet] public ActionResult Login() { var UserName = Request.Cookies["UserName"] == null ? "" : Request.Cookies["UserName"].Value; ViewBag.UserName = UserName; return View(); } public JsonResult CheckUserLogin(UserInfo userInfo) { using (EasyUIDemoDBEntities db = new EasyUIDemoDBEntities()) { //linq查询 var users = from p in db.UserInfo where p.Name == userInfo.Name && p.Password == userInfo.Password && p.Enable == true select p; if (users.Count() > 0) { userInfo = users.FirstOrDefault(); return Json(new { result = "success", content = "" }); } else { return Json(new { result = "error", content = "用户名密码错误，请您检查" }); } } }
view视图
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Login</title>
<script src="~/Scripts/jquery-1.7.1.min.js"></script>
<script type="text/javascript">
//异步实现用户的登录
function LoginUserInfo() {
$.ajax({
url: "../Login/CheckUserLogin",
type: "POST",
dataType: "json",
data: { "Name": $("#UserName").val(), "Password": $("#Password").val() },
success: function (data) {
if (data.result == "success") {
//window.location.href = "Home/GetView?viewPara=Index";
//window.location.href = "@Url.Content("/Home/Index/")";
alert(‘success‘);
//window.location.href = "/Home/Index";
}
else {
alert(data.content);
//window.location.href = "/Login/Login/";
}
},
error: function (xhr, error, ex) {
alert("erroraaaaa");
window.location.href = "/Login/Login/";
}
});
}
</script>
</head>
<body>
<div id="AddUserDialog" style="width: 300px; height: 160px; padding: 10px 20px" title="EasyUIDemo用户登录" >
<form id="ff">
<table id="tblAdd">
<tr>
<td>
<label for="UserName">用户名：</label></td>
<td>
<input type="text" id="UserName" name="UserName" value="@ViewBag.UserName" /></td>
<td>
</tr>
<tr>
<td>
<label for="Password">密 码：</label></td>
<td>
<input type="text" id="Password" name="Password" /></td>
</tr>
<tr>
<td colspan="2" style="text-align: center; padding-top: 10px">
<input type="button" value="提交" id="btnLogin" onclick="LoginUserInfo();"/>
</td>
</tr>
</table>
</form>
</div>
</body>
</html>
注意：在AJAX中提交地址如果在controller中不定义[httpget],则会访问第一个Loing的eAction
