我将index.html中的每个组件加载为
<script>
System.config({
map: { 'rxjs': 'node_modules/rxjs' },
packages: {
app: { format: 'register', defaultExtension: 'js' },
'rxjs': {defaultExtension: 'js'}
}
});
System.import('component_1/app/main')
.then(null, console.error.bind(console));
</script>
我所做的是,必须只有一个index.html,根据 System.config 中提供的路径,我将能够加载不同的组件。 如果我将index.html放在每个组件文件夹中,我可以加载组件,但我想通过调用该索引中每个组件的 main.ts ,只为所有组件使用一个index.html html的。
以下是我的代码详情。

export class AppComponent {
public record;

this.record = customers;

4.data.service.ts
import { Injectable } from 'angular2/core';
import { Http, Response } from 'angular2/http';
import 'rxjs/add/operator/map';
@Injectable()
export class DataService {
constructor(private http: Http) { }
getData() {
return this.http.get('../../uicomponent.json')
.map((res: Response) => res.json());
}
}

我已尝试过所有方法,但我的index.html没有重定向到我的main.ts来加载我的组件。
答案 0 :(得分:3)
您应该将每个component_*
文件夹定义到SystemJS配置中:
<script>
System.config({
map: {
'rxjs': 'node_modules/rxjs'
},
packages: {
'component_1': { format: 'register', defaultExtension: 'js' },
'component_2': { format: 'register', defaultExtension: 'js' },
(...)
'rxjs': {defaultExtension: 'js'}
}
});
System.import('component_1/app/main')
.then(null, console.error.bind(console));
这样您就可以在导入中使用component_*
(例如component_1
)。
如果您想保留配置并能够使用所有组件,则应将component_*
文件夹移到app
文件夹下...
