Router is a component that can take a component, and render it when the Browser URl matches the url prop

Note: this is only meant for vanilla JavaScript project. For Angular projects, use ion-router-outlet and the Angular router.

ion-route　属性(Properties)

Description	Name of the component to load/select in the navigation outlet (ion-tabs, ion-nav) when the route matches. The value of this property is not always the tagname of the component to load, in ion-tabs it actually refers to the name of the ion-tab to select.
Attribute	component
Type	string
componentProps

ion-route　事件(Events)
