Learn how to add a delete button and remove the contact and its information from the application in Marionette.

We'll cover the following...

Our goal is to enable the functionality of deleting a contact in our application. For that, we need to follow the steps provided in the figure below:

Add the “Delete” button

Now that we’ve got our contacts listed as we want them, let’s add a button to delete a contact:

<script type="text/template" id="contact-list-item"> 
    <td><%- firstName %></td>
    <td><%- lastName %></td>
    <td>
        <button class="btn btn-small"> 
            <i class="icon-remove"></i> 
            Delete
        </button>
    </td>
</script>

  • Lines 5–8: Generate a “Delete” button styled with Bootstrap.

  • Line 6: Add an icon to the button.

Add a column to the template

Since we’ve added a column to our child view, let’s keep things in sync by adding a column to the table template in line 6:

<script type="text/template" id="contact-list"> 
  <thead>
    <tr>
      <th>First Name</th> 
      <th>Last Name</th> 
      <th></th>
    </tr>
  </thead>
  <tbody>
  </tbody>
</script>

If we look at our page, we’ll see our “Delete” buttons. ...
