使用的浏览器-Chrome 67.0.3396.99
我创建了一个DialogsModule
,其中包含组件ConfirmDialog.component.ts
和以下模板confirm-dialog.component.html
Confirm-dialog.component.html
<mat-dialog>
<mat-dialog-title>{{title}}</mat-dialog-title>
<mat-dialog-content>{{message}}</mat-dialog-content>
<mat-dialog-actions>
<button type="button" mat-raised-button color="primary"
(click)="dialogRef.close(true)">Yes</button>
<button type="button" mat-button
(click)="dialogRef.close()">No</button>
</mat-dialog-actions>
</mat-dialog>
我收到以下错误
*Uncaught Error: Template parse errors:

1. If 'mat-dialog-title' is an Angular component, then verify that it is part of this module.
2. If 'mat-dialog-title' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("<mat-dialog> [ERROR ->]<mat-dialog-title>{{title}}</mat-dialog-title>

如果我从模板中删除
<mat-dialog>
和<mat-dialog-title>
元素,则一切正常。下面发布的是我的源代码。
Confirm-dialogs.component.ts
import { MatDialogRef } from '@angular/material';
import { Component } from '@angular/core';
@Component({
selector: 'confirm-dialog',
templateUrl: './confirm-dialog.component.html',
styleUrls: ['./dialogs.scss']
})
export class ConfirmDialog {
public title: string;
public message: string;
constructor(public dialogRef: MatDialogRef<ConfirmDialog>) {
}
}
Dialogs.module.ts
import { DialogsService } from './dialogs.service';
import { MatDialogModule, MatButtonModule } from '@angular/material';
import { NgModule } from '@angular/core';
import { ConfirmDialog } from './confirm-dialog.component';
@NgModule({
imports: [
MatDialogModule,
MatButtonModule,
],
exports: [
ConfirmDialog,
],
declarations: [
ConfirmDialog,
],
providers: [
DialogsService,
],
entryComponents: [
ConfirmDialog,
],
})
export class DialogsModule { }
dialogs.service.ts
import { Observable } from 'rxjs';
import { ConfirmDialog } from './confirm-dialog.component';
import { MatDialogRef, MatDialog, MatDialogConfig } from '@angular/material';
import { Injectable } from '@angular/core';
@Injectable({
providedIn: 'root'
})
export class DialogsService {
constructor(private dialog: MatDialog) { }
public confirm(title: string, message: string): Observable<boolean> {
let dialogRef: MatDialogRef<ConfirmDialog>;
dialogRef = this.dialog.open(ConfirmDialog);
dialogRef.componentInstance.title = title;
dialogRef.componentInstance.message = message;
return dialogRef.afterClosed();
}
}
最后是调用代码
let res1
this.dialogsService
.confirm('Confirm Dialog', 'Are you sure you want to do this?')
.subscribe(res => console.log(res));```
最佳答案
mat-dialog-title
应该用作指令而不是组件
<title mat-dialog-title>{{title}}<//title>
而且我也不认为angular/material有
mat-dialog
指令或组件。
