AJAX在聊天脚本中在线刷新用户

Question

我在here找到了我网站的聊天脚本 该脚本已经工作并刷新每条消息，但问题是用户在线列表没有刷新每个登录的新用户。

ajax代码

// Now let's load chatroom's active users       
function load_users(){
    // Let's use AJAX also to get chatroom's users
    $.ajax({
        url: "includes/actions.php?act=getusers",
        cache: false    
    });
}
setInterval(load_messages, 500);
setInterval(load_users, 500);  

actions.php脚本

function get_users(){

    global $tb_satker;
    // Let's get all info from "auth" table
    $sql = "SELECT * FROM $tb_satker WHERE status!=''";
    $query = mysql_query($sql);
    if(!$query){
        echo "Can not get users from database.";
    }else{
        while($row = mysql_fetch_array($query)){
            $namasatker=$row['nama_satker'];
            echo "<li><i class=\"icon-user\"></i>$namasatker</li>";
        }
    }

}

您需要一个显示返回HTML的成功函数：

function load_users(){
    // Let's use AJAX also to get chatroom's users
    $.ajax({
        url: "includes/actions.php?act=getusers",
        cache: false,
        success: function(response) {
            $("#onlineusers").html(response);
        }
    });
}
