“js操作cookie” 与 “php操作cookie”，两种实现方法

一、js操作cookie：

function SetCookie(name,value,days)//两个参数，一个是cookie的名子，一个是值
{
    var Days = 30;
    if(typeof(days)=="undefined"||isNaN(days))
        Days=parseInt(days.toString());
     //此 cookie 将被保存 30 天 -1为浏览器关闭　　
    if(Days!=-1){
        var exp = new Date();    //new Date("December 31, 9998");
        exp.setTime(exp.getTime() + Days*24*60*60*1000);
        document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
    }else{
        document.cookie = name + "="+ escape (value) + ";expires=-1";
    }
}

  

function getCookie(name)//取cookies函数
{
    var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
    if(arr != null) return unescape(arr[2]); return null;｝

function delCookie(name)//删除cookie
{   
    var exp = new Date();
    exp.setTime(exp.getTime() - (86400 * 1000 * 1));
    var cval=getCookie(name);
    if(cval!=null)
        document.cookie = name + "="+ escape (cval) + ";expires="+exp.toGMTString();｝

调用实例： 登陆时“记住我”设置cookie

//头部登陆框的验证函数
function checkform(objF){    
var cookieName_username="LOGIN_USER_NAME";
        var cookieName_password="LOGIN_PASSWORD";
            delCookie(cookieName_username);//删除用户名Cookie
            delCookie(cookieName_password);//删除密码       
            if(objF.autologin.checked)        
               { 
                  SetCookie(cookieName_username,objF.uname.value.trim(),7);//保存到Cookie中  保存7天      
                  SetCookie(cookieName_password,objF.password.value.trim(),7);   
                }
｝

调用实例： 获取cookie自动填充登陆框

  function getUserInfoByCookie(){
          var uname=getCookie(cookieName_username);           
            var upass=getCookie(cookieName_password);        
      
          if(uname!=null&&!uname.toString().isnullorempty())
               if(upass!=null&&!upass.toString().isnullorempty()){
                   document.getElementById("uname").value=uname;
                   document.getElementById("password").value=upass; ｝｝       

二、php操作cookie

实例：登陆时设置cookie

if($autologin=='1')
        {
            setcookie("account", $account, time()+1000,"/path/");
            setcookie("password", $password, time()+1000,"/path/");｝

实例：退出时删除cookie

setcookie("account", "", time()-3600,"/path/");
setcookie("password", "", time()-3600,"/path/");

实例：index.php获取cookie

 if (isset($_COOKIE["account"])&&isset($_COOKIE["password"])) {

        $account=$_COOKIE["account"];
        $account=$_COOKIE["password"];
}
