Introduction to adding a table row in jQuery: A step-by-step guide
jQuery is a popular JavaScript library that provides an easy way to manipulate the HTML DOM. One common task in web development is adding a new row to an HTML table dynamically. In this step-by-step guide, we will show you how to add a table row in jQuery.
Step 1: Create a basic HTML table
First, we need to create a basic HTML table. Here’s an example:
<table id="myTable">
<thead>
<tr>
<th>Name</th>
<th>Age</th>
</tr>
</thead>
<tbody>
<tr>
<td>John</td>
<td>25</td>
</tr>
<tr>
<td>Jane</td>
<td>30</td>
</tr>
</tbody>
</table>
Step 2: Add a button to trigger the table row addition
We will add a button to the HTML table to trigger the addition of a new row. Here’s an example:
<button id="addRow">Add Row</button>
Step 3: Write jQuery code to add a new row
Next, we will write the jQuery code to add a new row when the button is clicked. We will use the append() method to add a new row to the table’s body. Here’s an example:
$(document).ready(function() {
$('#addRow').click(function() {
$('#myTable tbody').append('<tr><td>New Name</td><td>New Age</td></tr>');
});
});
In this code, we first wait for the document to be ready. Then, we attach a click event to the addRow button. When the button is clicked, the jQuery code appends a new row to the table’s body with the values “New Name” and “New Age” in the name and age columns, respectively.
Step 4: Test the code
Now, we can test the code by opening the HTML file in a web browser and clicking the “Add Row” button. A new row should be added to the table.
Adding a table row dynamically in jQuery is a simple task. By following the above steps, you can easily add a new row to a table with the help of jQuery.

Using jQuery to dynamically add a new row to an HTML table
In web development, it’s common to need to add new rows to an HTML table dynamically using jQuery. This can be done easily using the jQuery append() method. In this guide, we’ll walk through the steps to add a new row to an HTML table using jQuery.
Step 1: Create a basic HTML table
First, let’s create a basic HTML table to add rows to. Here’s an example:
<table id="myTable">
<thead>
<tr>
<th>Name</th>
<th>Age</th>
</tr>
</thead>
<tbody>
<tr>
<td>John</td>
<td>25</td>
</tr>
<tr>
<td>Jane</td>
<td>30</td>
</tr>
</tbody>
</table>
Step 2: Create a form to enter new data
To add a new row to the table, we’ll need to create a form to enter new data. Here’s an example:
<form>
<label>Name:</label>
<input type="text" id="name"><br>
<label>Age:</label>
<input type="text" id="age"><br>
<button type="button" id="addRow">Add Row</button>
</form>
Step 3: Write jQuery code to add a new row
Now we can write the jQuery code to add a new row to the table. We’ll attach a click event to the “Add Row” button, and when it’s clicked, we’ll create a new row using the data entered in the form and append it to the table’s <tbody> element. Here’s an example:
$(document).ready(function() {
$('#addRow').click(function() {
var name = $('#name').val();
var age = $('#age').val();
$('#myTable tbody').append('<tr><td>' + name + '</td><td>' + age + '</td></tr>');
});
});
In this code, we first wait for the document to be ready. Then, we attach a click event to the “Add Row” button. When the button is clicked, we get the values entered in the form fields and store them in variables. Finally, we append a new row to the table’s <tbody> element using the append() method and the values entered in the form fields.
Step 4: Test the code
Now we can test the code by opening the HTML file in a web browser and entering values in the form fields, then clicking the “Add Row” button. A new row with the values entered in the form should be added to the table.
In this guide, we walked through the steps to dynamically add a new row to an HTML table using jQuery. By following these steps, you can easily add new data to a table in your web application.
How to add a row to a table using jQuery and AJAX
Adding a row to a table using jQuery and AJAX can be useful when you want to add data to a database without reloading the page. In this guide, we’ll show you how to use jQuery and AJAX to add a row to a table.
Step 1: Create a basic HTML table
First, let’s create a basic HTML table to add rows to. Here’s an example:
<table id="myTable">
<thead>
<tr>
<th>Name</th>
<th>Age</th>
</tr>
</thead>
<tbody>
<tr>
<td>John</td>
<td>25</td>
</tr>
<tr>
<td>Jane</td>
<td>30</td>
</tr>
</tbody>
</table>
Step 2: Create a form to enter new data
To add a new row to the table, we’ll need to create a form to enter new data. Here’s an example:
<form id="addForm">
<label>Name:</label>
<input type="text" name="name"><br>
<label>Age:</label>
<input type="text" name="age"><br>
<button type="submit">Add Row</button>
</form>
Step 3: Write jQuery code to handle form submission
Now we can write the jQuery code to handle form submission. When the form is submitted, we’ll prevent the default form submission behavior and use AJAX to submit the data to the server. Here’s an example:
$(document).ready(function() {
$('#addForm').submit(function(event) {
event.preventDefault();
$.ajax({
url: 'add_row.php',
method: 'POST',
data: $(this).serialize(),
success: function(data) {
$('#myTable tbody').append(data);
}
});
});
});
In this code, we first wait for the document to be ready. Then, we attach a submit event to the form using the submit() method. When the form is submitted, we prevent the default form submission behavior using preventDefault(). We then use AJAX to submit the data to a server-side script called add_row.php, which will insert the data into the database and return the new row HTML. When the AJAX call is successful, we append the new row HTML to the table’s <tbody> element using the append() method.
Step 4: Create a server-side script to insert data into the database
Now we need to create a server-side script to insert the data into the database. Here’s an example in PHP:
<?php
// Get the data from the AJAX request
$name = $_POST['name'];
$age = $_POST['age'];
// Insert the data into the database
// ...
// Return the new row HTML
echo '<tr><td>' . $name . '</td><td>' . $age . '</td></tr>';
?>
In this code, we first get the data from the AJAX request using $_POST. We then insert the data into the database using whatever method you prefer. Finally, we return the new row HTML using echo.
Step 5: Test the code
Now we can test the code by opening the HTML file in a web browser and entering values in the form fields, then clicking the “Add Row” button. The data should be inserted into the database and a new row with the entered data should be added to the table without the page being reloaded.
