remove a class from a row?

louking

Sorry I don't have a simple test case, but I think this may be a simple question.

I see from https://datatables.net/manual/ajax#Optional-parameters how to add a class to a row using DT_RowClass.

Is there any way to remove the class I added later?

Yes, use rows().nodes(). See the example in the docs.

I could probably make that work. But I was wondering if there is anything the server can send to tell datatables to remove the class on a given row.

Ultimately what I'm trying to do is color a row based on some data within the row.

I was able to use DT_RowAttr to get what I am looking for:

on server

        if row['is_confirmed']:
            row['DT_RowAttr'] = {'is_confirmed': True}
        else:
            row['DT_RowAttr'] = {'is_confirmed': False}

on client css

  table.dataTable tbody tr[is_confirmed="true"]
  {
      background-color: #99FF99;  /*green*/
  }

Another option is to use createdRow or rowCallback, if the data can change, to apply styling to the row or cells in a row based on a condiftion. See this example.
