'Invert selection' button?

krychaj5

Hi!
I'm loooking for code button which will invert selection in my rows.

For example: I have 10 rows, 4 selected / 6 unselected and I need button which will make it 6 selected / 4 unselected.

Is there any solution?

You can use the code snippets from the first two Select API examples here to create the invert selection button:
https://datatables.net/extensions/select/examples/api/index.html

Maybe something like this:

  var rows = table.rows( { selected: true } )[0] ;  //gets array of selected row numbers
  table.rows().select(); 
  table.rows(rows).deselect();

You can use the Datatables buttons as shown in the examples or create your on button with a click event handler.

Start by adding the select extension and setting it as an option during Datatables initialisation.
Kevin's code works fine then.

Start by adding the select extension....

The extension has to be included.

In addition to adding the code for the select extension you also need to create the table variable, something like this:
table = $('#example').DataTable( {

You can add the select extension code to your example by clicking Add Library.

Kevin's code looks just about spot on to me. The only thing I would say is to use rows().indexes() rather than rows()[0] on the first line. This is just the formal way to get the indexes, but really they amount of the same thing in the case of a single table API instance.
