Published on September 17, 2019 3 min read

Today I’m going to share how to make dynamic input fields using jQuery with add, remove option. Let’s start:

Table of Contents

  1. Include jQuery & Bootstrap
  2. Create a Simple Form
  3. Make Field Dynamic
  4. The Full Code
  5. Run and See the Output

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;">
            <a href="https://www.mynotepaper.com/" target="_blank"><img src="https://i.imgur.com/hHZjfUq.png"></a><br>
            <span class="text-secondary">Add or Remove Input Fields Dynamically using jQuery</span>
        </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
