In this article I will show you the logic and code behind facebook chat box popups. Many other websites like freelancer.com are using this kind of similar popups for implementing chat design. Therefore if you are planning to have a chatting functionality in your website then this article provide you the best help for designing it.

CSS Implementation

We need enough room for chat boxes and sidebar therefore we only display those if viewport width is greater than 540px. Even facebook does the same. Popup boxes and sidebar are fixed to the viewport.

Here is the CSS code:

            @media only screen and (max-width : 540px)
            {
                .chat-sidebar
                {
                    display: none !important;
                }
               
                .chat-popup
                {
                    display: none !important;
                }
            }
           
            body
            {
                background-color: #e9eaed;
            }
           
            .chat-sidebar
            {
                width: 200px;
                position: fixed;
                height: 100%;
                right: 0px;
                top: 0px;
                padding-top: 10px;
                padding-bottom: 10px;
                border: 1px solid rgba(29, 49, 91, .3);
            }
           
            .sidebar-name
            {
                padding-left: 10px;
                padding-right: 10px;
                margin-bottom: 4px;
                font-size: 12px;
            }
           
            .sidebar-name span
            {
                padding-left: 5px;
            }
           
            .sidebar-name a
            {
                display: block;
                height: 100%;
                text-decoration: none;
                color: inherit;
            }
           
            .sidebar-name:hover
            {
                background-color:#e1e2e5;
            }
           
            .sidebar-name img
            {
                width: 32px;
                height: 32px;
                vertical-align:middle;
            }
           
            .popup-box
            {
                display: none;
                position: fixed;
                bottom: 0px;
                right: 220px;
                height: 285px;
                background-color: rgb(237, 239, 244);
                width: 300px;
                border: 1px solid rgba(29, 49, 91, .3);
            }
           
            .popup-box .popup-head
            {
                background-color: #6d84b4;
                padding: 5px;
                color: white;
                font-weight: bold;
                font-size: 14px;
                clear: both;
            }
           
            .popup-box .popup-head .popup-head-left
            {
                float: left;
            }
           
            .popup-box .popup-head .popup-head-right
            {
                float: right;
                opacity: 0.5;
            }
           
            .popup-box .popup-head .popup-head-right a
            {
                text-decoration: none;
                color: inherit;
            }
           
            .popup-box .popup-messages
            {
                height: 100%;
                overflow-y: scroll;
            }

JavaScript Implementation

We do the following using JavaScript

  • Calculate the maximum number of popups can be displayed for the current viewport width.
  • Close popups
  • Newly opened popups overwrite the space given to the older popups.
  • Repositioning popups when viewport is resized.
  • Calculate the width and position of each popup.
  • Displaying popups when a item in sidebar is clicked.

This is the JavaScript code for these functionality.

            //this function can remove a array element.
            Array.remove = function(array, from, to) {
                var rest = array.slice((to || from) + 1 || array.length);
                array.length = from < 0 ? array.length + from : from;
                return array.push.apply(array, rest);
            };
       
            //this variable represents the total number of popups can be displayed according to the viewport width
            var total_popups = 0;
           
            //arrays of popups ids
            var popups = [];
       
            //this is used to close a popup
            function close_popup(id)
            {
                for(var iii = 0; iii < popups.length; iii++)
                {
                    if(id == popups[iii])
                    {
                        Array.remove(popups, iii);
                       
                        document.getElementById(id).style.display = "none";
                       
                        calculate_popups();
                       
                        return;
                    }
                }  
            }
       
            //displays the popups. Displays based on the maximum number of popups that can be displayed on the current viewport width
            function display_popups()
            {
                var right = 220;
               
                var iii = 0;
                for(iii; iii < total_popups; iii++)
                {
                    if(popups[iii] != undefined)
                    {
                        var element = document.getElementById(popups[iii]);
                        element.style.right = right + "px";
                        right = right + 320;
                        element.style.display = "block";
                    }
                }
               
                for(var jjj = iii; jjj < popups.length; jjj++)
                {
                    var element = document.getElementById(popups[jjj]);
                    element.style.display = "none";
                }
            }
           
            //creates markup for a new popup. Adds the id to popups array.
            function register_popup(id, name)
            {
               
                for(var iii = 0; iii < popups.length; iii++)
                {

                    if(id == popups[iii])

    Hi , first of all thank you for your wonderful work.
    I built upon this example to make a full chat application with php and jquery, although the javascript functions you made remained unmodified. On some occasions the popup close button does not close the popup, I also tried calling the close function from console, it returns “undefined”.
    I have no idea why this error occurs, I will be very grateful if you provided some hint on how I can resolve this issue.
    Thanks in advance.

    Popup box disapears after postback.

    I have a postback section:

    function isPostBack() {//Use during postbacks...

    }

    What part of the code do I have to put there to keep the popup box between postbacks?

      Because when:

      document.getElementsByTagName(“body”)[0].innerHTML = document.getElementsByTagName(“body”)[0].innerHTML + element;

      This code will change HTML body, so it would never load JQuery source

      use this:

      $(“body”).append(element);

      it will work

    i have a challenge; any time am chatting with two or more people, only one session of the chat works. example, suppose am chatting with Steve, it works well, but if am chatting with more than one user on the site one works.. (stephen.aryee69@gmail.com)

    here is the script that insert into the database

    HERE IS THE HTML:

    <a href="javascript:register_popup('’, ”);” ‘;?>

    $Uof[3] && $img[4]===”Male”)

    {

    ?>

    <li id='’ class=’holder normaltip’ title=’He is Online’><img src='profile-pics/’ class=’fri-online-img’/>

    $Uof[3] && $img[4]===”Female”)

    {

    ?>

    <li id='’ class=’holder normaltip’ title=’She is Online’><img src='profile-pics/’ class=’fri-online-img’/>

    <li id='’ class=’holder ‘normaltip’ title=’He is Offline’><img src='profile-pics/’ class=’fri-online-img’/>

    <li id='’ class=’holder normaltip’ title=’She is Offline’><img src='profile-pics/’ class=’fri-online-img’/>

    HERE IS THE JQUERY:

    $(document).ready(function() {

    // load messages every 1000 milliseconds from server.
    load_data = {‘fetch':1};

    window.setInterval(function(){

    var popups_id = $(“.chat-popup:last”).attr(‘id’); //id from Chat popUp window
    $.post(“sidebar_right/functions/writechat.php?tofriend=”+ popups_id, load_data, function(data) {
    $(‘.show_chatting-‘+ popups_id).html(data);
    });
    }, 1000);

    //method to trigger when user hits enter key
    $(“body”).on(“submit”, “form.chatting-form”, function (e){
    e.preventDefault();

    var popups_id2 = $(“.chat-popup”).attr(‘id’); //id from Chat popUp window
    var chat_with = $(this).attr(‘id’).replace(‘the_chat_’,”); //msg to
    var chat_msg = $(‘.chat_messages’).attr(“value”);

    if(popups_id2)
    {
    post_data = {‘username':chat_with, ‘message':chat_msg};

    //send data to “writechat.php” using jQuery $.post()
    $.post(‘configs/writechat.php’, post_data, function(data) {

    //append data into messagebox with jQuery fade effect!
    $(data).hide().appendTo(‘.show_chatting-‘+ chat_with).fadeIn();

    //reset value of message box
    $(‘.chat_messages’).val(”);

    });
    }
    });
    });

    HERE IS THE PHP

    <?php

    if($_POST)

    {

    if(isset($_POST["message"]))

    {

    $username = sanitizeString(trim($_POST["username"]));

    $message = sanitizeString(trim($_POST["message"]));

    if(queryMysql("INSERT INTO chat_messages VALUES(NULL,'$user','$username','$message','$insert_time', 1)"))

    {

    echo '’.timeAgo(time()).”.$message.”;

    }

    queryMysql(“DELETE FROM chat_messages WHERE chat_from=” OR message=””);

    }

    elseif($_POST[“fetch”]==1)

    {

    $results = queryMysql(“SELECT id, chat_with, chat_from, message, timesent FROM chat_messages WHERE (chat_from = ‘”.$_SESSION[‘user’].”‘ AND chat_with = ‘”.$_GET[‘tofriend’].”‘) OR (chat_with = ‘”.$_SESSION[‘user’].”‘ AND chat_from = ‘”.$_GET[‘tofriend’].”‘) ORDER BY chat_messages.id ASC”);

    while($row = mysql_fetch_array($results))

    $dfd = queryMysql(“SELECT fname,lname,image FROM rnmembers WHERE user = ‘”.$row[‘chat_from’].”‘”);

    $noms = mysql_fetch_row($dfd);

    }
    }
    }
    }
    ?>

    Hi there, great script. I have a few questions as I’d like to add a few things to this already wonderful chat/pop-up script but need your input. How can I minimize each pop by clicking on the pop-up head and it scrolls down to the pop-up head title…much like facebook’s functionality? It’s not as useful if you can only close it. Also, is there a way that you can create a tab simillar to that of facebook when you open a certain amount of pop you can scroll through the chat users in that tab button?

    Any help with code samples is very much appreciated as I am new to javascript/jQuery. Thank you.

    ReplyCancel
    • 6 years ago

      Follow the steps to achieve it:

      1. Create a new button in header.
      2. When user clicks on it call a JS function with box id as parameter.
      3. This function toggles the message area of the box.

      If I get time I will update the script also. Thanks.

      Follow these instructions to save the state of the popups between page reloads:

      1. Whenever u make changes to the popups[] array, make sure u send the array to your server using AJAX.

      2. During page load, make sure u retrieve the popups[] array value using AJAX and assign it.

To create code blocks or other preformatted text, indent by four spaces:

    This will be displayed in a monospaced font. The first four
    spaces will be stripped off, but all other whitespace
    will be preserved.
    
    Markdown is turned off in code blocks:

To create not a block, but an inline code span, use backticks:

Here is some inline `code`.
