Verify that the password is remembered when the page is initialized
$ (document). Ready (function () {
if ($.cookie ("rmbuser") = = "true") {//To determine if the password was remembered last login
$ ("#rmbUser"). attr ("Checked", true); The Set Remember password check box is selected

$.cookie (' name '); Read cookies
$ ("#user"). Val ($.cookie ("UserName"));
$ ("#pass"). Val ($.cookie ("PassWord"));
}
});

Save user Information
function Saveuserinfo () {
if ($ ("#rmbUser"). attr ("checked") = = True) {//If check box is selected to enter
var userName = $ ("#user"). Val ();
var PassWord = $ ("#pass"). Val ();
$.cookie ("Rmbuser", "true", {expires:7}); Storing cookies a cookie with a 7-day period
$.cookie ("UserName", UserName, {expires:7});
$.cookie ("PassWord", PassWord, {expires:7});
}
else {
$.cookie ("Rmbuser", "false", {Expires:-1}); Delete Cookies
$.cookie ("UserName", "', {Expires:-1});
$.cookie ("PassWord", "', {Expires:-1});
}
}

When you re-enter the page, the last information you entered will be recorded on the current page.

The above is the JS control, the backstage also need to be saved again

String userName = Request.getparameter ("UserName");
String Password = request.getparameter ("password");
String remember = Request.getparameter ("Remember");

Remember password in Save cookie
if ("Y". Equals (Remember)) {
Cookie username= New Cookie ("UserName", userName);

Cookie password= New Cookie ("PassWord", PassWord);
Cookie.setmaxage (60*60*24*7);//Save valid for seven days
Response.addcookie (UserName);
Response.addcookie (PassWord);
}

Here's how Java reads cookies and reads the cookie code as follows

 Cookie[] cookies = request.getCookies();//获取一个cookie数组  for(Cookie cookie : cookies){   Sysotem.out.println( cookie.getName());// get the cookie name   Sysotem.out.println(  cookie.getValue()); // get the cookie value }

Based on the information obtained above, you can check the call cookie when the user accesses the login page.

User name and password directly to query the corresponding user information login, so as to remember the password automatic login function
