Introduction

In this tutorial we will create a How to Create Automatic Image Slider in JavaScript. This tutorial purpose is to teach you on how to make an automatic image slider. This will cover all the important functionality that will automate the image slider. I will provide a sample program to show the actual coding of this tutorial.

This tutorial is simple and easy to understand just follow the instruction I provided and you can do it without a problem. This program can be use to any system or application if you want to apply an image slider. I will give my best to provide you the easiest way of creating this program Automatic Image Slider. So let's do the coding.

Before we get started:

Here is the link for the template that i used for the layout design https://getbootstrap.com/.

Creating The Interface

This is where we will create a simple interface for our application. This code will only display the html image format. To create this simply copy and write it into your text editor, then save it as index.html.

<!DOCTYPE html>
<html lang="en">
        <head>
                <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
                <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
        </head>
        <nav class="navbar navbar-default">
                <div class="container-fluid">
                        <a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
                </div>
        </nav>
<body>
        <div class="col-md-3"></div>
        <div class="col-md-6 well">
                <h3 class="text-primary">How to Create Automatic Image Slider</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="row">
                        <center><img src="images/image1.png" name="slideshow" height="280px" width="90%"></center>
                </div>
                <br />
                <center><img src="images/loading.gif" height="40" width="40px"></center>
        </div>
</body>
<script src="script.js"></script>
</html>

Creating JavaScript Function

This is where the main function of the application is. This code will automate the image slider with an interval duration. To do this just copy and write these block of codes inside the text editor and save it as script.js.

var image = new Array("images/image1.png", "images/image2.png", "images/image3.jpg", "images/image4.png", "images/image5.png");
var count = 0;
var length = image.length - 1;
 
 
function imageSlider(index){
        
        count = count + index;
 
        if(count > length){
                count = 0;
        }
        
        if(count < 0){
                count = length;
        }
        
        document.slideshow.src = image[count];
        
        return false;
}
 
 
autoSlideShow();
 
function autoSlideShow(){
        setInterval("imageSlider(1)", 5000);
}

This code will only uses only two method that will automate your image slider. The first method is called imageSlider(), this function is consist of transitioning the images display for each conditional statement you set. The last method will be called autoSlideShow(), this function will automate the image slider with set interval duration using the setInterval() function.
