access pictures from a different directory using JavaScript

I am working with an images array that contains three jpg files. I am trying to set the background image of a class called pic using images from the array.

The issue I'm facing is that the images are stored in an images folder with the URL images/. I need to add images/ to the line.

document.getElementById('content').style.backgroundImage = 'url('+images[index]+')';

Can anyone help me with this?

var images = ['bus.jpg','car.jpg','scooter.jpg' ];
var index = 0;

function buildImage() {
    document.getElementById('content').style.backgroundImage = 'url('+images[index]+')';
}

function changeImage() {
index++;
if (index >= images.length) index = 0;
    document.getElementById('content').style.backgroundImage = 'url('+ images[index] + ')';
}

<div class="pic" id="content" >

Answer №1

Simply combine the folder path with the image file names.

var images = ['bus.jpg','car.jpg','scooter.jpg' ];
var index = 0;
var FolderPath="Images/";

function buildImage() {
    document.getElementById('content').style.backgroundImage = 'url('+FolderPath+images[index]+')';
}

function changeImage() {
index++;
if (index >= images.length) index = 0;
    document.getElementById('content').style.backgroundImage = 'url('+FolderPath+ images[index] + ')';
}

Answer №2

When you are completely confident in the direction to take, feel free to implement it like so.

document.getElementById('display').style.backgroundImage = 'url('+ ImagePath + images[index] + ')';
