问题 I've come across this example where we can see: <md-menu #menu="mdMenu"> I can't find any reference to the ="mdMenu" part of this template in the docs. Is there some meaning to this or is it just a mistake on the example? 回答1: In the doc [mdMenuTriggerFor]="menu" refers to <md-menu #menu="mdMenu"> and in #menu="mdMenu" , mdMenu is the directive exported from Material. 来源： https://stackoverflow.com/questions/46581046/angular4-template-reference-variable-assignment

问题 I am building an angular 2 app in plain JS. My problem is that when I change from a page to another it flicker a white page until the new view is rendered. This happens for all components only first time I access them. If I go to same route second time the page is loaded without white page. I capture the screen to explain better my problem: https://drive.google.com/file/d/0B5pOsXT-4rdTbmtuVnlUdXRMdE0/view?usp=sharing Here is my main view: <router-outlet></router-outlet> <nav id="menu"> <a

问题 Short version This Plunker defines a <view> component which can render an arbitrary model+template. This needs to be changed to replace the previously rendered contents rather than appending new peers. EDIT: This is working now, thanks to the response by user3636086. One problem still remains: unlike Angular 1, Angular 2 forces me to create a nested component to update a template (since templates are effectively a static property of a component's class ), so I have a bunch of unnecessary DOM

问题 I'm new to angular in general and to angular2 specifically. I'm trying to write a container component, which should have child components in it.
