Delete each row in a table using JavaScript

I am working on an application that allows a user to click a delete button on a row in a table, then a confirmation modal should pop up; finally when you click yes, you should be able to delete that row. My code doesn't do that, instead it first deletes the header of which I only want to delete the row I specified, not the header. I used bootstrap for the css.

	function deleteRow(r) { 
	var i = r.parentNode.parentNode.rowIndex;
		document.getElementById("datatable-responsive").deleteRow(i);
		
		
		$('#confirm-delete').modal('hide');
		
	}
<table id="datatable-responsiv">	
  <thead align="center">
       <tr>
		<th>
          <input type="checkbox" name="prog" id="check-all" class="flat">
        </th>
         <th>Name of the video</th>
         <th>link</th>
         <th>Action</th>                          
       </tr>
  </thead>
  <tbody>
    <tr class="even pointer">
	<td class="a-center btnDelete" data-id="1">
    <input type="checkbox" class="flat" name="table_records">
    </td>
	<td>John </td>
	<td>https://www.youtube.com/watch?v=mU2Ej9PrMfY</td>
	<td>						  
     <button href="#" class="btn btn-primary btn-xs"><i class="fa fa-folder"></i> View </button>
     <button href="#" class="btn btn-info btn-xs"><i class="fa fa-pencil"></i> Edit </button>
    <button href="#" data-toggle="modal" data-target="#confirm-delete" class="btn btn-danger btn-xs btnDelete" ><i class="fa fa-trash-o"></i> Delete </button>
                           
</td>
</tr>
		<tr class="odd pointer">
		<td class="a-center btnDelete" data-id="2">
         <input type="checkbox" class="flat" name="table_records">
          </td>
			<td>James</td>
		<td>https://www.youtube.com/watch?v=ON3Gb9TLFy8</td>
						  
		<td>						  
          <button href="#" class="btn btn-primary btn-xs"><i class="fa fa-folder"></i> View </button>
                            <button href="#" class="btn btn-info btn-xs"><i class="fa fa-pencil"></i> Edit </button>
                           <button href="#" data-toggle="modal" data-target="#confirm-delete" class="btn btn-danger btn-xs btnDelete" ><i class="fa fa-trash-o"></i> Delete </button>
                          </td>
					  </tr>
					

				
					  </tbody>
					</table>



<!--model-->
<div class="modal fade" id="confirm-delete" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">

Use Element.parentNode.parentNode.remove();

function deleteRow(r) {
  r.parentNode.parentNode.remove();
  //$('#confirm-delete').modal('hide');
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<table id="datatable-responsiv">
  <thead align="center">
    <tr>
      <th>
        <input type="checkbox" name="prog" id="check-all" class="flat">
      </th>
      <th>Name of the video</th>
      <th>link</th>
      <th>Action</th>
    </tr>
  </thead>
  <tbody>
    <tr class="even pointer">

Assuming that the argument you're passing to your deleteRow function is a grand-child of the row you want to delete, your problem may be that you're calling deleteRow (the DOM method) on the table itself, not the table's tBody. Try

document.getElementById("datatable-responsive").tBodies[0].deleteRow(i);

(edit:) But Rayon's solution is more elegant anyway. Saves you the trouble of getting a reference to the tbody.
