RouterOutlet

一个占位符,Angular 会根据当前的路由器状态动态填充它。

Acts as a placeholder that Angular dynamically fills based on the current router state.

说明

Each outlet can have a unique name, determined by the optional name attribute. The name cannot be set or changed dynamically. If not set, default value is "primary".

      
      <router-outlet></router-outlet>
<router-outlet name='left'></router-outlet>
<router-outlet name='right'></router-outlet>
    

Named outlets can be the targets of secondary routes. The Route object for a secondary route has an outlet property to identify the target outlet:

{path: <base-path>, component: <component>, outlet: <target_outlet_name>}

Using named outlets and secondary routes, you can target multiple outlets in the same RouterLink directive.

The router keeps track of separate branches in a navigation tree for each named outlet and generates a representation of that tree in the URL. The URL for a secondary route uses the following syntax to specify both the primary and secondary routes at the same time:

http://base-path/primary-route-path(outlet-name:route-path)

每当新组件实例化之后,路由出口就会发出一个激活事件;在销毁时则发出取消激活的事件。

A router outlet emits an activate event when a new component is instantiated, and a deactivate event when a component is destroyed.

<router-outlet (activate)='onActivate($event)' (deactivate)='onDeactivate($event)'></router-outlet>
      
      <router-outlet
  (activate)='onActivate($event)'
  (deactivate)='onDeactivate($event)'></router-outlet>
