重新加载组件时，角度ngOnInit强制触发

Question

I'm using Angular2 and gonna load content on Settings page for every account.

URL structure below

URL1 http://example.com/account/NICKNAME_1/settings
URL2 http://example.com/account/NICKNAME_1/orders

URL3 http://example.com/account/NICKNAME_2/settings
URL4 http://example.com/account/NICKNAME_2/orders

If I'm going from URL1 to URL3 (or URL3 to URL1) then ngOnInit doesnt fire for settings component . This is expected behavior because Angular trying not to reload component.

Subscribing on changing params in settings component doesnt solve the issue because there are no parameters.

How can I detect changing Account name inside of Settings component ?

You'll find the account name as a param on the route parent:

route.parent.params.subscribe(...)
