angular - 将数据发送到 TemplateRef MatDialog

Question

如何将数据发送到作为 ng-template 的 MatDialog？

模板

<button mat-button (click)="openDialog()">Open</button>

<ng-template #dialogRef>
    {{data?}} <!-- <<< Here is the problem data is undefined -->
</ng-template>

组件

export class SomeComponent {
    @ViewChild("dialogRef") dialogRef: TemplateRef<any>;

    constructor(private dialog: MatDialog) { }

    openDialog(): void {
        this.dialog.open(this.dialogRef, { data: "some data" });
    }
}

Answer 1

它应该通过模板变量可用:

<ng-template #dialogRef let-data>
                        ^^^^^^^^
   {{data}}
</ng-template>
