等待数据，然后在Angular 2中渲染视图

Question

It's not another question about resolve I think. I would like to have simple, complex method to wait for Ajax data before rendering component in Angular 2. I will have about fifty routes, so creating resolve for each route would be pain.

Can someone share his way to wait for data before rendering view?

Answer 1

• a resolver https://angular.io/docs/ts/latest/guide/router.html#!#resolve-guard

• *ngIf="data" in the view, to prevent rendering of the view while data is null

• use the safe-navigation operator data?.prop to prevent error in view bindings while data is null
