Creating The Interface

This is where we will create a simple interface for our application. This code will display the html table and buttons. To create this simply copy and write it into your text editor, then save it as index.html.

<!DOCTYPE html>
<html>
	<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">How to Dynamically Remove Table Row</h3>
		<hr style="border-top:1px dotted #ccc;"/>
		<table id="table" class="table table-bordered">
			<thead class="alert-info">
				<tr>
					<th>Firstname</th>
					<th>Lastname</th>
					<th>Address</th>
					<th>Gender</th>
					<th>Age</th>
					<th>Action</th>
				</tr>
			</thead>
			<tbody>
				<tr>
					<td>John</td>
					<td>Smith</td>
					<td>USA</td>
					<td>Male</td>
					<td>26</td>
					<td><button class="btn btn-danger" onclick="removeRow(this)">Remove</td>
				</tr>
				<tr>
					<td>Claire</td>
					<td>Temple</td>
					<td>USA</td>
					<td>Female</td>
					<td>21</td>
					<td><button class="btn btn-danger" onclick="removeRow(this)">Remove</td>
				</tr>
				<tr>
					<td>Tony</td>
					<td>Rogers</td>
					<td>New York</td>
					<td>Male</td>
					<td>35</td>
					<td><button class="btn btn-danger" onclick="removeRow(this)">Remove</td>
				</tr>
				<tr>
					<td>Bobby</td>
					<td>Roberson</td>
					<td>Italy</td>
					<td>Male</td>
					<td>31</td>
					<td><button class="btn btn-danger" onclick="removeRow(this)">Remove</td>
				</tr>
			</tbody>
		</table>
	</div>
<script src="script.js"></script>
 
</body>
</html>

Creating JavaScript Function

This is where the main function of the application is. This code will dynamically remove a row from table when the button is clicked. To do this just copy and write these block of codes inside the text editor and save it as script.js.

function removeRow(row) {
  let i = row.parentNode.parentNode.rowIndex;
  document.getElementById("table").deleteRow(i);
}

In the code above we will just create a method called removeRow(). This function will dynamically remove the row of the button you just have clicked. Inside the function we first create a variable that will hold the index position of the row. Lastly we will target our table row and use the deleteRow() function
