jQuery how to fix Cannot set property '_DT_CellIndex' of undefined? - php

Question

I'm new in Jquery and I want once the user adds new row and give the important information once he clicks on "Ajouter" button it will add on data base then reload the table automatically.
Once i run that I found that the data added successfully to the database however "tablebqup" does not reload anymore and it I found this error :
Uncaught TypeError: Cannot set property '_DT_CellIndex' of undefined
Here is the function to add the new element:
$("#newbq").click(function () {
var indexadd= $('table#tablebqup tr:last').index() + 1;
//Now add this row to the table:
var row='<tr><td></td><td contenteditable="true"></td><td contenteditable="true"></td><td contenteditable="true"></td><td contenteditable="true"></td><td contenteditable="true"></td><td colspan="2"> <button id="add'+indexadd+'" class="btn btn-info addbc" name="button">Ajouter</button> </td></tr>';
$('#tablebqup').append(row);
$(".addbc").click(function () {
var nombc=($(this).parent().parent().find('td:eq(1)').html());
var abrv= ($(this).parent().parent().find('td:eq(2)').html());
var sigsoc=($(this).parent().parent().find('td:eq(3)').html());
var telf=($(this).parent().parent().find('td:eq(4)').html());
var fx=($(this).parent().parent().find('td:eq(5)').html());
// if (nombc=="" || abrv=="" || sigsoc=="" || (telf=="" && fx==""))
if (nombc=="")
{
alert("Rempier toutes les informations de la banque d'abord")
}
else {
$choix=confirm("voulez vous vraiment ajouter la banque");
if ($choix)
{
console.log(nombc);
$.post(basUrl+'views/component/updtbq.php',
{
action:'add_bq',
nomb:nombc,
abrvb:abrv,
sigsocial:sigsoc,
tel:telf,
fax:fx,
}, function(data) {
alert(data);
$('#tablebqup').DataTable().ajax.reload();//My problem is here
});
}
}
});
});
In the fist time one i run it it showed something like this :
“Uncaught TypeError: $(…).DataTable is not a function”
To solve it i added the appropriate link and script:
Doing that the error has changed to :
Uncaught TypeError: Cannot set property '_DT_CellIndex' of undefined
What surprised me that i have used above similar logic I mean use the same:
$('#tablebqup').DataTable().ajax.reload();
and once I click another button just to modify information on data base in this way :
$(".modif").click(function () {
$choix=confirm("voulez vous vraiment sauvegarder les modifications");
if ($choix)
{
var id=($(this).parent().parent().find('td:eq(0)').html());// the value in the 1st column.
var nombc=($(this).parent().parent().find('td:eq(1)').html());
var abrv= ($(this).parent().parent().find('td:eq(2)').html());
var sigsoc=($(this).parent().parent().find('td:eq(3)').html());
var telf=($(this).parent().parent().find('td:eq(4)').html());
var fx=($(this).parent().parent().find('td:eq(5)').html());
console.log(id);
$.post(basUrl+'views/component/updtbq.php',
{
action:'update_bq',
idbc:id,
nomb:nombc,
abrvb:abrv,
sigsocial:sigsoc,
tel:telf,
fax:fx,
}, function(data) {
$('#tablebqup').DataTable().ajax.reload();
});
}
That work perfectly without adding any of this two links!!!

$i++;
}
echo'
</form>
</tbody>
</table>
</div>
<button type="button" class="btn btn-info" name="button" id="newbq" >Nouvelle banque</button>
</div>
</div>';
I thought that maybe the problem is because i allow the user to not filling all the informations, but i want that it gonna be in this way the user enters just the important field.
How could I solve this problem?Can someone help.

Answer 1

It gives me this error when the number of td doesnt match the number of th, or when I use colspan...
Depending on your css, it could be hard to see. I'd add a border to the table while testing it out...

Answer 2

A simple mistake, the table header had a column " with no title, but the column did not exist in the table itself. I could not see it missing (because o no title and no borders).
Was helped by looking at the line in the datatable.js which gave the error - was implying a tr was at fault, so looked more carefully at my table and not my overall code

Answer 3

From your code, I don't see the DataTabe initialization, usually placed inside the Document Ready function. So:
Try to Initialize your table with an explicit configuration for each column ("visible:true" is a dummy setting that just confirms it is visible)
Add the "datatable" class to your table html. Example:
Example:
$(document).ready(function () {
var myTable= $('#tablebqup').DataTable({
columns:[
//"dummy" configuration
{ visible: true }, //col 1
{ visible: true }, //col 2
{ visible: true }, //col 3
{ visible: true }, //col 4
{ visible: true }, //col 5
{ visible: true }, //col 6
{ visible: true }, //col 7
{ visible: true } //col 8
]
});
});
And on the html:
<table id="tablebqup" class="tableau table datatable table-fixed table-bordered table-dark table-hover ">
Explanation:
The "DataTable" initialization method should have the same number of columns on its configuration as the number of <th>'s/<td>'s on your html.
Wrong example:
//Javascript Code
var myTable= $('#myTableId').DataTable({
columns: [
//any column configuration
{ "bSearchable": false }, //col 1
{ "bSearchable": true }, //col 2
{ "bSearchable": true }, //col 3
{ "bSearchable": false }, //col 4
{ "bSearchable": false }, //col 5
{ "bSearchable": false } //col 6
]
});
And the html markup:
<table id="myTable" class="table datatable">
<thead>
<tr>
<th>col 1 header</th>
<th>col 2 header</th>
<th>col 3 header</th>
<th>col 4 header</th>
</tr>
</thead>
<tbody>
<tr>
<td> data col 1, row 1</td>
<td> data col 2, row 1</td>
<td> data col 3, row 1</td>
<td> data col 4, row 1</td>
</tr>
</tbody>
</table>
So even if the number of <td>'s and <tr>'s are matching on the html, having more columns configured on the DataTable method will cause this exception to be thrown. In this example, removing the configuration lines for col 5 and col 6 from the DataTable method would fix the error.

Answer 4

I had correct number of columns in thead-th section and tbody-td section. There was no colspan added on any th or td elements but I was getting the same issue. I did some more research and found that I disabled sorting feature on a column number which was not exist in my data table.
Actually I had only 4 columns in my data table while I was trying to disable sorting feature for 6th number column. It was an accident. I forgot to change it. Code was as:
$(document).ready(function()
{
$('#datatable').DataTable( {
"aoColumnDefs": [
{ 'bSortable': false, 'aTargets': [0,1,6] }
],
responsive: true,
});
});
Then I changed 'aTargets' value, which could be set upto 3 as per my case and correct code was as:
$(document).ready(function()
{
$('#datatable').DataTable( {
"aoColumnDefs": [
{ 'bSortable': false, 'aTargets': [0,1,3] }
],
responsive: true,
});
});
It worked for me. Happy to share and help others :)
