如何记住用户名和密码使用记住我的cookie [英] How to Remember the username and password using remember me in cookies

问题描述

大家好。

i需要ASP.Net中以下概念的解决方案

当用户输入用户名和密码并选中记住我复选框时，它将被存储系统内cookie中的用户名和密码。

每当用户再次登录时，在文本框中输入用户名时，必须从cookie自动加载密码。同时cookie必须存储多个用户名和密码。



这是代码

解决方案

试试这个：



下次在asp.net的登录控制中记住我 [ ^ ]



http://www.c-sharpcorner.com/uploadfile/raj1979/login-control-in-Asp-Net-3-5/ [<一个href =http://www.c-sharpcorner.com/uploadfile/raj1979/login-control-in-Asp-Net-3-5/target =_ blanktitle =New Window> ^ ]

嗨亲爱的，如果你使用TextBox控件作为用户名和密码，你可以按照这个。

 受保护  void  btn_Click（  object  sender，EventArgs e）
 {
  //   GetValues（）;  
 HttpCookie cookie =  new  HttpCookie（  UserName）; 
 cookie.Values.Add（ this  .userName.Text， this  .password.Text） ; 
 Response.Cookies.Add（cookie）; 
} 

这里有一些javascript代码



< pre lang =Javascript>< pre>函数readTheCookie（）{
var the_cookie = document .cookie;
if （the_cookie！= ）{
document .getElementById（' <％= password.ClientID％>'）。value = the_cookie.split（' ='）[ 2 ];
}
}

Hi, everyone
i Need solution for the following concept in ASP.Net
When the user types username and password with the "Remember ME" checkbox checked it will stored the username and password in the cookie inside the system.
Whenever the user logins again, when username is entered in the textbox the password must be automatically loaded from the cookie. simultaneously the cookie must store multiple username and passwords.

Here is the code for
CS.aspx

//
//if(document.getElementById('chkRememberMe').checked)
//{

//else
//{
//alert("Check box is not selected ");

//}
//}

function readCookie()
{

var txtuname= document.getElementById('txtUserName');
var txtpass= document.getElementById('txtPassword');

debugger

if (document.cookie.length>0)
{
var c_start=document.cookie.indexOf(txtuname.value);
//alert(document.cookie);
//alert("to search txtvalue "+txtuname.value);

if (c_start!=-1)

Try this:

Remember me next time in login control in asp.net[^]

Hi Dear if you are using TextBox controls for username and password you can follow this.

protected void btn_Click(object sender, EventArgs e)
        {
            //GetValues();
            HttpCookie cookie = new HttpCookie("UserName");
            cookie.Values.Add(this.userName.Text, this.password.Text);
            Response.Cookies.Add(cookie);
        }

here is some javascript code

<pre>function readTheCookie() {
            var the_cookie = document.cookie;
            if (the_cookie != "") {
                document.getElementById('<%=password.ClientID %>').value = the_cookie.split('=')[2];
            }
        }
