Creating The Interface

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

<!DOCTYPE html>
<html lang="en">
        <head>
                <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
                <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
                <style>
                        ul{
                                padding:0;
                        }
                        ul li{
                                display:inline;
                        }
                </style>
        </head>
<body>
        <nav class="navbar navbar-default">
                <div class="container-fluid">
                        <a class="navbar-brand" href="https://sourcecodeter.com">Sourcecodester</a>
                </div>
        </nav>
        <div class="col-md-3"></div>
        <div class="col-md-6 well">
                <h3 class="text-primary">How to Display Image Base on List</h3>
                <hr style="border-top:1px dotted #ccc;">
                <h4>My List</h4>
                        <ul>
                                <li style="cursor:pointer;" onclick="displayImage('naruto.png');">Naruto,</li>
                                <li style="cursor:pointer;" onclick="displayImage('bleach.jpeg');">Bleach,</li>
                                <li style="cursor:pointer;" onclick="displayImage('onepiece.jpg');">One Piece,</li>
                                <li style="cursor:pointer;" onclick="displayImage('dragonball.jpg');">Dragon Ball,</li>
                                <li style="cursor:pointer;" onclick="displayImage('hunterxhunter.jpg');">Hunter x Hunter</li>
                </ul>
                <div id="result">
                        <center><h1>BLANK IMAGE</h1></center>
                </div>
        </div>
<script src="script.js"></script>
</body>
</html>

Creating JavaScript Function

This is where the main function of the application is. This code will change your background image dynamically base on the chosen list. To do this just copy and write these block of codes inside the text editor and save it as script.js.

function displayImage(img){
        var result=document.getElementById('result');
        result.innerHTML="<img src='images/"+img+"' width='100%' height='350px'/>";
}

The code above is very simple and understandable, we will only create one method and we will name it displayImage(). This function will dynamically change your background image when an event is trigger. To change the image you just set the value for the image and make sure your image name in folder is the same as image value.
