Submitted by razormist on Tuesday, February 25, 2020 - 22:43.

In this tutorial we will create a Remove Table Row using JavaScript. This code will dynamically remove a single row when the user click the delete button. The code use onclick() to call a specific function that will remove single row of data by applying the array index as the parameter in the removeRow(). This is a free kind of program, feel free to modify it and use it as your own. We will use JavaScript to add some new feature to the website interface by actually written into an HTML page. It is what gives your page a different interactive elements and animation that engage a user.

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">Remove Table Row Using JavaScript Source Code</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="col-md-6"></div>
                <div class="col-md-6">
                <table class="table table-bordered">
                        <thead class="alert-info">
                                <tr>
                                        <th>Name</th>
                                        <th>Action</th>
                                </tr>
                        </thead>
                        <tbody id="result"></tbody>
                </table>
                </div>
        </div>
</body>
<script src="js/script.js"></script>
</html>

Creating the Script

This code contains the script of the application. This code will remove a sing row when the button is clicked. 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 directory

var members = ["Steve Roger", "NAtasha Romanof", "Bruce Banner", "Luke Cage", "Jessica Jones",];
        
displayData();
 
function removeRow(index){
        alert("You have remove " + members[index]);
        members.splice(index, 1);
        displayData();
}
 
function displayData(){
        var table = "" ;
        
        for(var i=0; i < members.length; i++){
                table += "<tr>";
                table += "<td>" + members[i] +"</td>"
                                + "<td><button class='btn btn-danger' onclick='removeRow("+i+")'><span class='glyphicon glyphicon-trash'></span> Remove</button></td>";
                table += "</tr>";
        
        }
        
        document.getElementById("result").innerHTML = table;
}
