Java uses the SSM framework to implement the login page remember password function

The final effect shows:

1. Login Page JSP code

<label class= "checkbox" >     <input type= "checkbox" Name= "RememberMe" id= "RememberMe" onclick= "Remember ();" /> Remember Password </label>

　　　　  Select Remember password trigger event, assign value to 1 if checked, or 0        function remember () {            var Remflag = $ ("Input:checkbox"). Is (': checked ');            if (remflag) {                 //cookie the user name and password, the echo is the real user name and password, there is a security issue                . var conflag = confirm ("Record password function should not be used in public places in order to prevent password leakage." Are you sure you want to use this feature? ");                if (conflag) {                     //Confirm flag                    $ ("#rememberMe"). Val ("1");                } else{                    $ ("Input:checkbox"). Removeattr (' checked ');                    $ ("#rememberMe"). Val ("0");                }            } else{                 //If set Remflag is not selected as ""                $ ("#rememberMe"). Val ("0");}        }

Start function to get the user information saved in the cookie
$ (function () {
The cookie Data preservation format is key=value;key=value; form, Logininfo is the key value stored in the cookie, specifically see Controller code            var str = GetCookie (" Logininfo ");            str = str.substring (1,str.length-1);            var username = str.split (",") [0];            var password = str.split (",") [1];            Auto-populate user name and password            $ ("#username"). Val (username);            $ ("#password"). val (password);

});

Get cookie        function GetCookie (CNAME) {             var name = cname + "=";            var ca = Document.cookie.split (';');            for (var i=0; i<ca.length; i++) {                var c = ca[i];                while (C.charat (0) = = ") c = c.substring (1);                if (C.indexof (name)! =-1) return c.substring (Name.length, c.length);            }            Return "";        }

2. Controller code after login request

Create cookie object, save user information, set cookie expiration time, add cookie via response
if ("1". Equals (Cookieflag)) {   String Logininfo = Username + "," + password;   Cookie Usercookie = new Cookie ("Logininfo", logininfo);   Usercookie.setmaxage (1 * 24 * 60 * 60); Survival period is one day 1*24*60*60   usercookie.setpath ("/");   Res.addcookie (Usercookie);}
