dev Session和计时器完成弹窗无刷新

js代码

var pcLogin;
var tbLogin;

var timer; //声明一个定时器变量

//window.onload = function () {
// pcLogin = ASPxClientPopupControl.Cast('pcLogin');
// tbLogin = ASPxClientButton.Cast('tbLogin');
//}

function pcLogin_Init(s, e) {
ShowLoginWindow();
}

var sesstionTime; //什么一个变量去接收这个值
function Setimeout(time) { //这个方法可以拿到Web.config 从的Session 过期值
sesstionTime = time;
}

//隐藏弹窗
function CloceLoginWindow() {
pcLogin.Hide();
}

function ShowLoginWindow() {debugger
clearInterval(timer);//初始化定时器时间
var dateTime = sesstionTime;//Session过期时间赋值给dateTime;
timer = setInterval(function () { //定时器时间设定
pcLogin.Show();
}, dateTime * 60000); //设置时间 dateTime 1秒 = 1000毫秒这是定时器的计算单位为毫秒 600000

}

//登录按钮
function Start() {
debugger
var tbLogin = tbLogins.GetText(); //获取Textbox值
var tbPassword = tbPasswords.GetText();

$.ajax({
url: '/ajax/Gps.ashx?action=LoginVerification',
data: { tbLogin: tbLogin, tbPassword: tbPassword },
type: 'post',
dataType: 'json',
success: function (r) {
if (r.info == "ok") {
CloceLoginWindow();
//window.location.reload(); 强制刷新页面的实现代码
} else {
alert("用户名或密码不正确 .");
pcLogin.Show();
}
}
});
}

后端代码如果你的后端代码是写在 IHttpHandler 里面的化请引用 using System.Web.SessionState;

不然 SessionHelper.InsertSessionUser(user);获取不到Session的值

private void LoginVerification(HttpContext context)
{
PlatformUser user = null;
var tbLogin = context.Request.Form["tbLogin"];
var tbPassword = context.Request.Form["tbPassword"];

string encyptPass = DESEncrypt.Encrypt(tbPassword, GpsSetting.EncryptKey);
AccountDAL account = new AccountDAL();

user = account.GetValidUser(tbLogin, encyptPass);
string state = string.Empty;
if (user != null)
{
SessionHelper.InsertSessionUser(user);
state = "ok";
}

JsonResult jr = new JsonResult
{
info = state,
//data = dt
};

IsoDateTimeConverter timeFormat = new IsoDateTimeConverter();
timeFormat.DateTimeFormat = "yyyy-MM-dd HH:mm:ss";

context.Response.Write(JsonConvert.SerializeObject(jr, timeFormat));
context.Response.End();
}

还有前端代码

<%-- 登录页面 --%>

CloseAction="None" Width="300px" Height="200px" ShowCloseButton="False" CloseOnEscape="True" Modal="True"

<ContentStyle>
<Paddings PaddingBottom="5px" />
</ContentStyle>
</dx:ASPxPopupControl>

Web.config

SessionHelper

using GpsWeb.Model;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace GpsWeb.Helper
{
public class SessionHelper
{
public static void InsertSessionUser(PlatformUser user)
{
HttpContext ctx = HttpContext.Current;
ctx.Session[GpsSetting.SessionKey] = user;
}

public static PlatformUser GetSessionUser()
{
HttpContext ctx = HttpContext.Current;
var obj = ctx.Session[GpsSetting.SessionKey];
if (obj == null) return null;
return (PlatformUser)ctx.Session[GpsSetting.SessionKey];
}

}
}
