JavaScript - Populate HTML Table With Arrays

Submitted by razormist on Tuesday, December 17, 2019 - 11:19.
In this tutorial we will create a Populate HTML Table With Arrays using JavaScript. This code will populate table rows with arrays when user click the populate button. The code itself use a onclick() to call a specific function that can populate table rows in the table using for() loop to breakdown the array one by one and assign in a variable to display. You can apply this script to your code, it is a user-friendly program feel free to modify it. We will use JavaScript to add some new feature to the website interface by actually written into an HTML page. It is what gives your page a different interactive elements and animation that engage a user. .

Getting Started:

First you have to download bootstrap framework, this is the link for the bootstrap that I used for the layout design https://getbootstrap.com/.

The Main Interface

This code contains the interface of the application. To create this just write these block of code inside the text editor and save this as index.html.
  1. <!DOCTYPE html>
  2. <html lang="en">
  3.         <head>
  4.                 <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
  5.                 <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
  6.         </head>
  8.         <nav class="navbar navbar-default">
  9.                 <div class="container-fluid">
  10.                         <a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
  11.                 </div>
  12.         </nav>
  13.         <div class="col-md-3"></div>
  14.         <div class="col-md-6 well">
  15.                 <h3 class="text-primary">JavaScript - Populate HTML Table With Arrays</h3>
  16.                 <hr style="border-top:1px dotted #ccc;"/>
  17.                 <div class="col-md-8">
  18.                         <table class="table table-bordered">
  19.                                 <thead class="alert-info">
  20.                                         <tr>
  21.                                                 <th>Firstname</th>
  22.                                                 <th>Lastname</th>
  23.                                                 <th>Address</th>
  24.                                         </tr>
  25.                                 </thead>
  26.                                 <tbody id= "result"></tbody>
  27.                         </table>
  28.                 </div>
  29.                 <div class="col-md-4">
  30.                         <center><button type="button" onclick="populateTable()" class="btn btn-primary">Populate Table</button></center>
  31.                 </div>
  32.         </div>
  33. </body>
  34. <script src="js/script.js"></script>
  35. </html>

Creating the Script

This code contains the script of the application. This code will populate the table row when the button is clicked. To do this just copy and write these block of codes as shown below inside the text editor and save it as script.js inside the js directory
  1. var data = [
  2.         {firstname: "John", lastname: "Smith", address: "New York"},
  3.         {firstname: "Claire", lastname: "Temple", address: "Racoon City"}
  4. ];
  5.        
  6. function populateTable(){
  7.         var table = "" ;
  8.        
  9.                 for(var i in data){
  10.                         table += "<tr>";
  11.                         table += "<td>"
  12.                                         + data[i].firstname +"</td>"
  13.                                         + "<td>" + data[i].lastname +"</td>"
  14.                                         + "<td>" + data[i].address +"</td>" ;
  15.                         table += "</tr>";
  16.                 }
  17.        
  18.         document.getElementById("result").innerHTML = table;
  19.                
  20. }
