In this tutorial we will create a Update Profile Background When Dragged using JavaScript. This code will change the user profile background when the image drag in the box. The code use ondragstart to fetch the image information before dragging it, then will change the background profile using ondrop. This is a user-friendly kind of program, feel free to modify it and use it on your system. We will be using JavaScript as a scripting or programming language that allows you to implement complex things on web pages. It is widely used in designing a stunning website. It is an interpreted programming language that has a capabilities of Object-Oriented.

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.

<!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"/>
        </head>
<body>
        <nav class="navbar navbar-default">
                <div class="container-fluid">
                        <a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
                </div>
        </nav>
        <div class="col-md-3"></div>
        <div class="col-md-6 well">
                <h3 class="text-primary">JavaScript - Update Profile Background When Dragged</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <br /><br />
                <div class="col-md-4">
                        <h5>My List</h5>
                        <img src="images/image1.jpg" id="images/image1.jpg" height="100" width="100" draggable="true" ondragstart="drag(event)"/>
                        <img src="images/image2.jpeg" id="images/image2.jpeg" height="100" width="100" draggable="true" ondragstart="drag(event)"/>
                        <img src="images/image3.jpg" id="images/image3.jpg" height="100" width="100" draggable="true" ondragstart="drag(event)"/>
                        <img src="images/image4.jpeg" id="images/image4.jpeg" height="100" width="100" draggable="true" ondragstart="drag(event)"/>
                </div>
                <div class="col-md-8">
                        <center><h2>My Profile Background<//center>
                        <div style="border:1px solid #000; height:250px; width:350px;" ondrop="drop(event)" ondragover="dragOver(event)"></div>
                </div>
        </div>
<script src="js/script.js"></script>
</body>
</html>

Creating the Script

This code contains the script of the application. This code will change the profile background when dragging the image to the drop zone. 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 folder.

function dragOver(e){
        e.preventDefault();
}
        
function drop(e){
        e.preventDefault();
        var data = e.dataTransfer.getData("data");
        e.target.innerHTML = "";
        e.target.style.backgroundImage = "url('"+data+"')";
        e.target.style.backgroundRepeat = "no-repeat";
        e.target.style.backgroundSize = "cover";
        e.target.style.backgroundPosition = "Center";
        
}
 
function drag(e){
        e.dataTransfer.setData("data", e.target.id);
}
