Loading data into HTML Tables using AJAX – JavaScript Tutorial

Code Canyon

In most medium-to-large sized websites or applications, it’s ideal to separate your data from your HTML markup. One way to achieve this is by creating a structure in HTML and then loading the data separately from a dedicated data-file.

AJAX is a method of loading data into a web page once it has finished loading – using JavaScript.

In this video I take you through an example of where we populate a HTML table with rows and cell data that comes from an external JSON file. We go through the steps of making the HTTP request, parsing the content and then manipulating the DOM to finally render the data to the user.

    Thank you for this. Got it to work but I want to locate it in an external JS file. When I do this I get the "could not get rankings" error. Any idea why this is?

    I follow along but fail at 8:34 with the following error message:

    Could not load rankings!

    request.onload @ index.html:61

    load (async)

    loadRankings @ index.html:56

    (anonymous) @ index.html:71

    what is this problem about and how to solve it?

    Here is the code:

    <script type="text/javascript">

    const rankingsBody = document.querySelector("#ranking-table > tbody");

    function loadRankings () {

    const request = new XMLHttpRequest();


    request.onload = () => {

    try {

    const json = JSON.parse(request.responseText);


    } catch (e) {

    console.warn("Could not load rankings!");





    function populateRankings (json) {



    document.addEventListener("DOMContentLoaded", () => {loadRankings(); });

    Hi very good tutorial I been wanting to do something like that before but I could't, I can do it now but if I add more data to each array it won't run, like more than 3 columns. Does the array have to be the same? Can they contain empty cells or null values?

    "one": "Laurie",

    "two": "Rowland"


    "points": 2019

    It looks cool! But, I have a little problem: Getting the data from a PHP file using the json_encode method, the resulting JSON it's very different from the one you created, because is made of arrays and the json are made of objects. Could you make a video teaching how to do it in that case? I will appreciate it a lot
    Thanks for this video

    Great video! How do you make the table rows you created with JSON data selectable? I noticed there aren't any good videos out there showing how to do that…

    11:00 instead of renaming, you can simply put:

    throw new Error("message");
