我有一个 CustomDialog,我将它用作确认对话框,并在其中将我的外部组件显示为模式对话框。我想在其中注入一个在 TS 文件中创建的动态 formGroup。在我使用 Metro4 组件之前,该组件在对话服务中具有如下方法:
<mat-dialog-content>
<ng-template #renderComponent>'I used this section to show component'</ng-template>
<div *ngIf="data.form" [formGroup]="form">
'I want to inject formgroup hier'
'like injecting as an formGroup in data.form parameter'
</div>
</mat-dialog-content>
那是TS代码:
import { FormGroup } from '@angular/forms';
import { AfterViewInit, Component, Inject } from "@angular/core";
import { MatDialogRef, MAT_DIALOG_DATA } from "@angular/material/dialog";
import { ViewChild, ComponentFactoryResolver, ViewContainerRef, ComponentRef } from "@angular/core";
@Component({
selector: 'custom-dialog',
templateUrl: './custom-dialog.component.html',
styleUrls: ['./custom-dialog.component.scss']
})
export class CustomDialogComponent implements AfterViewInit {
@ViewChild("renderComponent", { read: ViewContainerRef })
vcRef: ViewContainerRef;
componentRef: ComponentRef<any>;
form: FormGroup;
constructor(public dialogRef: MatDialogRef<CustomDialogComponent>,
private resolver: ComponentFactoryResolver,
@Inject(MAT_DIALOG_DATA) public data: any) {
}
ngAfterViewInit() {
const comp = this.resolver.resolveComponentFactory(this.data.component);
this.componentRef = this.vcRef.createComponent(comp);
}
ngOnDestroy() {
if (this.componentRef) {
this.componentRef.destroy();
}
}
}
但现在我想使用 Angular Material UI,我想创建上面提到的东西。我想知道我该怎么做。
例如,我这样称呼我的 CustomDialog:
const myForm = new FormGroup({
email: new FormControl('', [Validators.required,
Validators.email])});
const dialogRef = this.dialogService.open(CustomDialogComponent,
{
hasBackdrop: true,
disableClose: true,
panelClass: 'myapp-no-padding-dialog',
data: {
title: 'Title',
*formGroup: myForm*
}
});
