我有一个典型的Angular 2应用程序,其中包含许多组件
我安装了这个模态组件:https://github.com/pleerock/ng2-modal。
有没有办法在更多组件之间共享相同的模态?
我解释得更好。我希望在单击不同组件内的不同按钮时打开相同的模态。可能吗?
我试过这种方法 https://plnkr.co/edit/RgI1e9PobC7FloLHpEFD?p=preview 但这不是正确的方法,因为它总是为模态添加内容。
我将它发布在app.ts文件下面:

按照@echonax的建议,我更新了我的插件:
//our root app component
import {
NgModule,
ComponentRef,
Injectable,
Component,
Injector,
ViewContainerRef,
ViewChild, ComponentFactoryResolver} from "@angular/core";
import {BrowserModule} from '@angular/platform-browser'
import {Subject} from 'rxjs/Subject';
@Injectable()
export class SharedService {
showModal:Subject<any> = new Subject();
}
@Component({
selector: 'child-component',
template: `
<button (click)="showDialog()">show modal from child</button>
`,
})
export class ChildComponent {
constructor(private sharedService:SharedService) {}
showDialog() {
this.sharedService.showModal.next(CompComponent);
}
}
@Component({
selector: 'comp-comp',
template: `MyComponent`
})
export class CompComponent { }
@Component({
selector: 'modal-comp',
template: `
<div class="modal fade" id="theModal" tabindex="-1" role="dialog" aria-labelledby="theModalLabel">
<div class="modal-dialog largeWidth" role="document">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title" id="theModalLabel">The Label</h4></div>
<div class="modal-body" #theBody>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal" (close)="close()">Close</button>
</div></div></div></div>
`
})
export class ModalComponent {
@ViewChild('theBody', {read: ViewContainerRef}) theBody;
cmp:ComponentRef<any>;
cmpRef:ComponentRef<any>;
constructor(
sharedService:SharedService,
private componentFactoryResolver: ComponentFactoryResolver,
injector: Injector) {
sharedService.showModal.subscribe(type => {
if(this.cmp) {
this.cmp.destroy();
}
let factory = this.componentFactoryResolver.resolveComponentFactory(type);
this.cmpRef = this.theBody.createComponent(factory)
$('#theModal').modal('show');
});
}
close() {
if(this.cmp) {
this.cmp.destroy();
}
this.cmp = null;
}
}
@Component({
selector: 'my-app',
template: `
<div>
<h2>Hello</h2>
<button (click)="showDialog()">show modal</button>
<child-component></child-component>
</div>
`,
})
export class App {
constructor(private sharedService:SharedService) {}
showDialog() {
this.sharedService.showModal.next(CompComponent);
}
}
@NgModule({
imports: [ BrowserModule ],
declarations: [ App, ModalComponent, CompComponent, ChildComponent],
providers: [SharedService],
entryComponents: [CompComponent],
bootstrap: [ App, ModalComponent ]
})
export class AppModule{}

那个plunker的原始版本实际上是我的问题:How to dynamically create bootstrap modals as Angular2 components?
@Günter做出了一个惊人的答案,我认为这个答案真的被低估了。
plunker有一个小错误,你可以在这里找到固定版本:https://plnkr.co/edit/oMCZIJq58WdLgYf2D0Di?p=preview
if个案引用了错误的字段,因此请更改
if(this.cmp) {
this.cmp.destroy();
}
与
if(this.cmpRef) {
this.cmpRef.destroy();
}

我知道这个话题已经有6个月了,但实现这一目标对我来说真的很重要。
所以我创建了一个npm模块,允许在共享数据和远程打开/关闭/事件的组件之间共享模式。
随时查看:https://github.com/biig-io/ngx-smart-modal。
演示在这里:https://biig-io.github.io/ngx-smart-modal/
与Angular&gt; = 2.0.0
兼容
