How to disable "sorting by nothing" of the third click on column header?

jstuardo

Hello. I don't know if this is possible to do, but in my case this causes a problem.

Normal behaviour about Datatable ordering is as follow.

• First click on column header, sort ascending by that column
• Second click on column header, sort descending by that column
• Third click on column header, no sorting at all occur. If using server side processing, no order[0] element is posted to the server.

How can I avoid third click behaviour?

For instance, I need:

• First click on column header, sort ascending by that column
• Second click on column header, sort descending by that column
• Third click on column header, sort ascending by that column
• Fourth click on column header, sort descending by that column
• And so on

Is that possible? Or maybe a workaround?

thanks
Jaime

The columns.orderSequence docs have the answer. Use this to revert to the default Datatalbes 1.x behavior:

DataTable.defaults.column.orderSequence = ['asc', 'desc'];
