同一页上的角2的多个组件 [英] Angular 2 More than one component on same page

问题描述

我是从角2快速启动code工作app.component.ts文件。

I am working from the Angular 2 quick start code on app.component.ts file.

文件看起来是这样的：

import {Component} from 'angular2/core';

@Component({
    selector: 'app',
    template: `<h1>Title Here</h1>'
})
export class AppComponent { }

这正常工作。

我想要做的就是添加此同一页上的另一个组成部分...所以我想这样的：

What I want to do is to add another component on this same page ... so I tried this:

import {Component} from 'angular2/core';
import {ComponentTwo} from 'angular2/core';

@Component({
    selector: 'app',
    template: `<h1>Title Here</h1>'
}),

@Component({
    selector: 'appTwo',
    template: `<h1>Another Title Here</h1>'
})
export class AppComponent { }

这不工作...难道我做错了什么，或者这是不允许的？

This doesn't work...Is it that I'm doing something wrong or is this not allowed?

推荐答案

您不能有相同的选择两根组件在你的页面，你也不能有两个 @Component（） 在同一类的装饰器。

You can't have two root components with the same selector in your page, you also can't have two @Component() decorators on the same class.

如果您的组件有不同的选择，只需要运行引导每一根组件

If your components have different selectors, just run bootstrap for each root component

@Component({
    selector: 'app',
    template: '<h1>AppComponent1</h1>'
})
export class AppComponent1 { }

@Component({
    selector: 'appTwo',
    template: '<h1>AppComponent2</h1>'
})
export class AppComponent2 { }


bootstrap(AppComponent1)
bootstrap(AppComponent2)

有是一个悬而未决的问题，以支持重写选择器可以添加一个根组件多次结果

There is an open issue to support overriding the selector to be able to add a root component multiple times
