When I try running my JavaScript code in the console, it works perfectly fine. However, I encounter an error when I attempt

Recently, I added a cool JavaScript code to my website that changes the background of the landing page randomly. Here is the snippet:

var bgImages = [ 
                   "url('assets/bg/front1.jpg')",
                   "url('assets/bg/front2.jpg')",
                 ];
var randomIndex = Math.floor(Math.random() * 2) + 0;
document.getElementById("front").style.backgroundImage = bgImages[randomIndex];

Upon loading the page, I noticed an error in the console:

background.js:6 Uncaught TypeError: Cannot read property 'style' of null
    at background.js:6

Strangely, when I manually run this script through the console, it works smoothly. Any suggestions or solutions would be greatly appreciated. Thank you in advance!

Answer №1

The issue could potentially arise from placing the script tag before the body tag. Try moving the script tag after the body tag. If Javascript is unable to locate your element, it indicates that it has not been displayed on the browser yet, resulting in an error when trying to access it.
