Prevent page change if a form is dirty using webix-jet

Hi again :slight_smile:

I’m looking for a clean way to prevent user to loose some changes in a webix form in a webix-jet context.

Below an example:

  1. go to the form page
  2. type something in the textarea or the text input, the label "dirty return … " will be updated
  3. when dirty return TRUE, and if the user click “start” in the sidebar, i’d like to webix.confirm something, and depending of the result, allow page change or not.

Thank you :kissing_heart:

Everything already here, sorry for noise
