Fra*_*ank 6 components view angular
我能够成功创建一个按钮,在单击时将我的组件的另一个实例加载到DOM中,但是它将它加载到我希望它在其中的组件之外,这会导致CSS关闭.当我将"editorComponents"添加到我的页面时,它目前看起来像这样:
但我希望它看起来像这样:
您可以从检查中看到,在第二个示例中,所有标签都被手动移动到我想要的位置.
现在我的代码如下:
home.component.html
<div class="row backgroundContainer">
<div class="col-md-7 componentContainer">
<app-editor></app-editor>
<button (click)="addEditor()" type="button">Add Editor</button>
</div>
<div class="col-md-5 componentContainer">
<app-bible></app-bible>
</div>
<div id="footerBox">
<app-footer></app-footer>
</div>

import { Component, OnInit, ViewContainerRef, ComponentFactoryResolver } from '@angular/core';
import { EditorComponent } from '../editor/editor.component';

templateUrl: './home.component.html',

那么当我动态地将EditorComponent添加到我的页面时,如何将它直接添加到我的html中的当前"app-editor"下面呢?

你需要使用自己的ViewContainerRef.目前您正在注入root one,因为您可以看到附加到的所有组件<app-root>.
import { Component, OnInit, ViewContainerRef, ComponentFactoryResolver } from '@angular/core';
import { EditorComponent } from '../editor/editor.component';
@Component({
selector: 'app-home',
templateUrl: './home.component.html',
styleUrls: ['./home.component.scss']
})
export class HomeComponent implements OnInit {
// Setup custom viewChild here
@ViewChild('container', { read: ViewContainerRef }) viewContainerRef: ViewContainerRef;
constructor(private componentFactoryResolver: ComponentFactoryResolver) {}
ngOnInit() {
}
addEditor() {
const factory = this.componentFactoryResolver.resolveComponentFactory(EditorComponent);
const ref = this.viewContainerRef.createComponent(factory);
ref.changeDetectorRef.detectChanges();
}
}
