Javascript Question

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">
<div class="modal-dialog">
<div class="modal-content">

<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
<h4 class="modal-title" id="myModalLabel">Confirm Delete</h4>
</div>

<div class="modal-body">
<p>You are about to delete one track, this procedure is irreversible.</p>
<p>Do you want to proceed?</p>
<p class="debug-url"></p>
</div>

<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<button type="button" class="btn btn-danger btn-ok" value="Delete" onclick="deleteRow(this)">Delete</button>
</div>
</div>
</div>
</div>




Answer

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.
