How to provide information to canDeactivate in Aurelia view-model

Question

I am using canDeactivate() in a view-model. There is a way for the user to navigate away from the view where canDeactivate should not do its checks and just return true (in this case, when the user presses a Back button which is in another view). It appears that canDeactivate does not take any arguments (such as the params passed to router.navigateToRoute). If it did, I could indicate that the Back button was pressed in the params arg when calling navigateToRoute. What would be a good way to give canDeactivate this needed piece of information?

Answer 1

starting in aurelia-router 1.4.0, canDeactivate is passed an argument which contains the information you need to accomplish this
