RootRenderer
Injectable service that provides a low-level interface for modifying the UI.
已弃用: Use RendererFactory2 instead.
abstract class RootRenderer {
abstract renderComponent(componentType: RenderComponentType): Renderer
}
说明
Use this service to bypass Angular's templating and make custom UI changes that can't be expressed declaratively. For example if you need to set a property or an attribute whose name is not statically known, use setElementProperty or setElementAttribute respectively.
If you are implementing a custom renderer, you must implement this interface.
The default Renderer implementation is DomRenderer. Also available is WebWorkerRenderer.
