updating data-order in html

JensAlsted

Hi

I have a table that is updated via html. This is working as im calling dt.rows().invalidate().draw() as an update event.
I have now added that i update the class of a TD and also the data-order on the same TD. The class change is reflected fine as I can see the new class redered on the screen.
My rows on the other hand does not re-order according to the new data-order.
The ordering given in the config works initially and will again reorder if i do a full page reload.
Any pointers to what i could be missing here?

Thanks
Jens

How are you updating the data-order attribute?

You need to use `jQuery attr() instead of jQuery data() to update the DOM for Datatables to use. From the jQuery data() docs

Using the data() method to update data does not affect attributes in the DOM. To set a data-* attribute value, use attr.

If this doesn't help please provide a link to your page or a test case replicating the issue so we can help debug.

If you update the attribute, you would also need to call row().invalidate() to have DataTables update its cache of the data.
