Hi.
If I understood correctly the question, you can use the CanDeactivate
guard to implement logic to detect if a component has changes. The logic
will be executed before changes to a new component.

Hi,
I use components and in it propertys of own models.
When I change the route I want to know the property items are
manipulated or not.
(In that case there should be a warning like "You want to save changes?")
My focus is on *how to detect changes of the model object?*
Frank
What I have and use looks like...
my-model.ts
|
exportclassMyModel{myId:string,name:string,team:teamMember[]constructur(){this.team
=[];}}
|
my-app.component.ts
|
import{MyModel}from'@core/models/my-model';
@Component({...})
exportclassMyApp{
myModel:MyModel;
// here I want to detect changes of myModel(e.G.at OnClose() or
OnDestroy())
|
Thanks for help!
Frank
