Issue with programmatic change row information

scsbreese

The documentation indicates that data and add both take a JS array or object.
However, row().data($data) fails if the object is of HTMLTableRow type.

row.add($data) works regardless of the type.

For instance, this works:

$html = $.parseHTML($.trim(html));
            
$dRow = dataTable.row.add($html);
$data = $dRow.data();
$dRow.remove();
            
dataTable.row($rowIndex).data($data).draw();

While this fails:

$html = $.parseHTML($.trim(html));
            
dataTable.row($rowIndex).data($html).draw();

It seems to work okay here when giving it an HTML row: http://live.datatables.net/haqotuhe/1/edit .

Can you link to a test case showing the issue please?

Sure, the issue is not with the add function but with the data function:

Oh I see - but the row().data() method won't accept a node - at least there is nothing in the documentation to suggest that it will (if there is, please let me know where so I can remove it).

The row().data() method will accept an object (as in a plain Javascript object), or an array of data - matching the data structure that has already been used for that row.

Nothing in the documentation for row().data() indicates that it won't accept a node either and it has the same parameter descriptions as row.add() which would indicate that if the add accepts a node, the data should also.

The description of the set data parameter for each function is identical, therefore, I think I should expect them to behave in the same way.

Ultimately, I found a way around it (as is shown in my first post) but was confused as to why both functions required a different object of data.

Good point - thank you! The row.add() documentation is incomplete. I will fix that shortly.

Good to hear that you got a workaround!

Thanks for your help and your great work on this plugin.

I've just added a little bit more information to the documentation. It will be deployed to the site in the next update.

I think I can improve on the documentation beyond this - I've got a note to spend a little time on those two methods!
