Submitted by razormist on Friday, August 23, 2019 - 14:34.
In this tutorial we will create a Dynamic Drag And Drop Delete Image using JavaScript. This code will dynamically delete the image when drop in the drop zone.The code use JavaScript drag and drop feature in order to dynamically remove the image by providing an id in the ondragstart() event. A user-friendly program so that you can modify and understand it without an ease. We will be using JavaScript as a server-side scripting language that interpret a program to extend a whole new level of HTML experience. A scripting language that use in different ways that provide a whole level of experience when visiting a website.

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. 
  1. <!DOCTYPE html>
  2. <html lang="en">
  3. 	<head>
  4. 		<meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1" />
  5. 		<link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
  6. 	</head>
  7. <body>
  8. 	<nav class="navbar navbar-default">
  9. 		<div class="container-fluid">
  10. 			<a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
  11. 		</div>
  12. 	</nav>
  13. 	<div class="col-md-3"></div>
  14. 	<div class="col-md-6 well">
  15. 		<h3 class="text-primary">JavaScript - Dynamic Drag And Drop Delete Image</h3>
  16. 		<hr style="border-top:1px dotted #ccc;"/>
  17. 		<div class="col-md-8">
  18. 			<img id="img1" src="image/image1.jpg" height="80" width="120" style="border:1px solid #000; float:left; margin-left:10px;" draggable="true" ondragstart="drag(event)"/>
  19. 			<img id="img2" src="image/image2.jpg" height="80" width="120" style="border:1px solid #000; float:left; margin-left:10px;" draggable="true" ondragstart="drag(event)"/>
  20. 			<img id="img3" src="image/image3.jpg" height="80" width="120" style="border:1px solid #000; float:left; margin-left:10px;" draggable="true" ondragstart="drag(event)"/>
  21. 		</div>
  22. 		<div class="col-md-4">
  23. 			<center><img src="image/trash.png" height="150" width="150" ondrop="drop(event)" ondragover="dragOver(event)"/></center>
  24. 		</div>
  25. 	</div>
  26. <script src="js/script.js"></script>	
  27. </body>	
  28. </html>

Creating the Script

This code contains the script of the application. This code will delete the draggable image when drop the target zone. To do this just copy and write these block of codes inside the text editor, then save it as script.js inside the js folder. 
  1. function dragOver(e){
  2. 	e.preventDefault();
  3. }
  4.  
  5. function drop(e){
  6. 	e.preventDefault();
  7. 	var data = e.dataTransfer.getData("data");
  8. 	var el = document.getElementById(data);
  9. 	el.parentNode.removeChild(el);
  10. 	alert("Image deleted!");
  11. }
  12.  
  13. function drag(e){
  14. 	e.dataTransfer.setData("data", e.target.id);
  15. }
There you have it we successfully created a Dynamic Drag And Drop Delete Image using JavaScript. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
