JavaScript - Drag And Drop Form Inputs Generator

Submitted by razormist on Tuesday, February 19, 2019 - 10:59.

In this tutorial we will create a Drag And Drop Form Inputs Generator using JavaScript. JavaScript is a scripting or programming language that allows you to implement complex things on web pages. It is a text-based programming language meant to run as part of a web-based application. It is an interpreted programming language that has a capabilities of Object-Oriented. So Let's do the coding...

Getting Started:

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 - Drag And Drop Form Inputs Generator</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="col-md-12" style="height:75px; border:1px solid #000; text-align:center; padding-top:2%;">
                        <label style="font-size:30px;" id="input1" draggable="true" ondragstart="drag(event)">Textbox</label> |
                        <label style="font-size:30px;" id="input2" draggable="true" ondragstart="drag(event)">Radio</label> |
                        <label style="font-size:30px;" id="input3" draggable="true" ondragstart="drag(event)">Checkbox</label> |
                        <label style="font-size:30px;" id="input4" draggable="true" ondragstart="drag(event)">Select</label>
                </div>
                <br style="clear:both;"/><br />
                <div class="col-md-3"></div>
                <div class="col-md-6" style="border:1px solid #000; height:200px; padding-top:10%; padding-left:10%;" ondrop="drop(event)" ondragover="dragOver(event)">
                        <h2>DROP HERE</h2>
                </div>
        </div>
<script src="js/script.js"></script>    
</body> 
</html>

Creating the Script

This code contains the script of the application. This code will generate form inputs by just dragging. 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");
        
        switch(data){
                case "input1":
                        e.target.innerHTML = "<input type='text' placeholder='Texbox'>";
                        break;
                case "input2":
                        e.target.innerHTML = "<p><input type='radio'>Radio Button</p>";
                        break;  
                case "input3":
                        e.target.innerHTML = "<p><input type='checkbox'>Checkbox</p>";
                        break;
                case "input4":
                        e.target.innerHTML = "<select><option>Select an option</option><option>Example 1</option><option>Example 2</option></select>";
                        break;
        }
}
 
function drag(e){
        e.dataTransfer.setData("data", e.target.id);
}

There you have it we successfully created a Drag And Drop Form Inputs Generator 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!
