vue-router: Maintaining routing consistency despite argument changes

I am currently working on verifying the unsaved form route before leaving, and in case the user declines, I want to prevent changing the route.

Most of it is functioning properly with 

beforeRouteLeave: function (to, from, next) { 
                      if (!confirm('Leaving form')) next(false);
                   }

The issue arises when dealing with route arguments, such as #/form-path?id=5 - modifying the id argument does not trigger the beforeRouteLeave method.

Is there a different hook that I can utilize to halt navigation when an argument changes?

Answer №1

Dynamic route matching is a unique feature aimed at linking various paths or URLs to the same route or component. Therefore, modifying the argument does not technically result in leaving the route, hence beforeRouteLeave won't be triggered.

Nevertheless, I propose that the corresponding component of the route should be responsible for detecting argument changes. Essentially, whenever there's a change in the argument, document the modification and then reverse it (hopefully the reversal process is quick enough to go unnoticed by the user), followed by requesting confirmation. If the user confirms the change, utilize the documentation to revert back the change; however, if the user declines, maintain the current state (do not undo the reversal).

I haven't personally tested this approach, so I cannot guarantee its effectiveness, but hopefully, it sheds light on which part of the application is tasked with monitoring changes.
