Add or Remove Input Fields Dynamically using jQuery
Today I’m going to share how to make dynamic input fields using jQuery with add, remove option. Let’s start:
Table of Contents
Step 1 : Include jQuery & Bootstrap
It is not necessary to include Bootstrap. I’m going to include Bootstrap to make a simple design. We will include jQuery & Bootstrap’s CDNs. Here are the CDN links:
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css"> <script src="//ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
Step 2 : Create a Simple Form
Let’s create a simple form including one text field. We will make the text field dynamic:
<form method="post" action="">
<div class="row">
<div class="col-lg-12">
<div id="inputFormRow">
<div class="input-group mb-3">
<input type="text" name="title[]" class="form-control m-input" placeholder="Enter title" autocomplete="off">
<div class="input-group-append">
<button id="removeRow" type="button" class="btn btn-danger">Remove</button>
</div>
</div>
</div>
<div id="newRow"></div>
<button id="addRow" type="button" class="btn btn-info">Add Row</button>
</div>
</div>
</form>Step 3 : Make Field Dynamic
We have created a simple form with one text field. We are going to make the text field dynamic using jQuery. Here’s the jQuery code:
<script type="text/javascript">
// add row
$("#addRow").click(function () {
var html = '';
html += '<div id="inputFormRow">';
html += '<div class="input-group mb-3">';
html += '<input type="text" name="title[]" class="form-control m-input" placeholder="Enter title" autocomplete="off">';
html += '<div class="input-group-append">';
html += '<button id="removeRow" type="button" class="btn btn-danger">Remove</button>';
html += '</div>';
html += '</div>';
$('#newRow').append(html);
});
// remove row
$(document).on('click', '#removeRow', function () {
$(this).closest('#inputFormRow').remove();
});
</script>Step 4 : The Full Code
We have finished all the tasks. Here’s the full code:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<title>Add or Remove Input Fields Dynamically using jQuery - MyNotePaper</title>
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">
<script src="//ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
</head>
<body>
<div class="container"style="max-width: 700px;">
<div class="text-center" style="margin: 20px 0px 20px 0px;">

</div>
<form method="post" action="">
<div class="row">
<div class="col-lg-12">
<div id="inputFormRow">
<div class="input-group mb-3">
<input type="text" name="title[]" class="form-control m-input" placeholder="Enter title" autocomplete="off">
<div class="input-group-append">
<button id="removeRow" type="button" class="btn btn-danger">Remove</button>
</div>
</div>
</div>
<div id="newRow"></div>
<button id="addRow" type="button" class="btn btn-info">Add Row</button>
</div>
</div>
</form>
</div>
<script type="text/javascript">
// add row
$("#addRow").click(function () {
var html = '';
html += '<div id="inputFormRow">';
html += '<div class="input-group mb-3">';
html += '<input type="text" name="title[]" class="form-control m-input" placeholder="Enter title" autocomplete="off">';
html += '<div class="input-group-append">';
html += '<button id="removeRow" type="button" class="btn btn-danger">Remove</button>';
html += '</div>';
html += '</div>';
$('#newRow').append(html);
});
// remove row
$(document).on('click', '#removeRow', function () {
$(this).closest('#inputFormRow').remove();
});
</script>
</body>
</html>Step 5 : Run and See the Output

Links
You can add links by adding text inside of [] and the link inside of (), like so:
Lists
To add a numbered list you can simply start with a number and a ., like so:
1. The first item in my list
For an unordered list, you can add a dash -, like so:
- The start of my list
Images
You can add images by selecting the image icon, which will upload and add an image to the editor, or you can manually add the image by adding an exclamation !, followed by the alt text inside of [], and the image URL inside of (), like so:
