How to add a confirm prompt for page change?

York

I added a confirm prompt for page change, by using the page.dt event (https://datatables.net/reference/event/page).

How can I cancel the page change when the confirm prompt returns false?

There is no option to cancel the paging (it isn't mentioned anywhere in the documentation because there is no option to do that). The page event is simply to inform you that the paging has changed after it has changed.

You would need to create a custom paging plug-in if you wanted to be able to confirm the paging change.

Here is a trick to do so.

Use option preDrawCallback to cancel a draw.
Use page.dt and length.dt to reset the page/length controller value.

A simplified version is here. http://jsfiddle.net/ktbf8day/19/.

This version responses to all draw event, but not limited to specific ones. Just preDrawCallback is needed.

A confirm prompt is useful to prevent user from losing data in edit mode.
