Strange behavior with diacritic filtering

andrew45

I came across some strange behavior which I was able to reproduce in a showcase (link is below).

Data to my datatable are from AJAX (the ID and CATEGORY columns). The ZODIAK column's data originate from the CATEGORY column by simple copying with some JS.

The strange behavior is that.
When I select Bliźnięta or Koziorożec (these values are with diacritics) in the CATEGORY column, everything is OK.

But when I select the same in the ZODIAK column, I get "No matching records found". When in the ZODIAK column I select other values (without diacritics), everything is OK as well.

How is it possible and how to fix the problem without deleting diacritics or sending all the data from AJAX?

Looks like you need to add my_table.draw(); after the for loop:

The draw() API typically should be called after making changes to the table to allow Datatbles to update the filters, etc.

FYI you can get an instance of the Datatable API by using this.api(). I updated the test case to show this.

Thanks, Kevin, your changes did the job. But I wonder why it worked with values without diacritics.

DataTables stores a "normalised" string that it uses for filtering without diacritics, so searching with them finds nothing. It works for the global filter as it will also remove the diacritics, but when you are calling it yourself, it keeps them, hence the issue. DataTable.util.diacritics() can be used to normalise the string.
