Question

我使用Angular Material和Angular 6。我在材质对话框上做了很多工作，我做了这样的事情：

openDialog3(key : string): void {
  let dialogRef = this.dialog.open(PPSDialogRemoveComponent, {width: '1000px'}); 
  dialogRef.componentInstance.key = key;
}

现在我想使用角形材质底片。要将密钥传递到我的底部组件，请尝试以下操作：

  openBottomSheet(key: string): void {
    let dialogRef = this.bottomSheet.open(BottomSheetOverviewExampleSheet);
    dialogRef.componentInstance.key = key;
}

但是我有这个错误

src / app / geo / geo.component.ts（568,15）中的
ERROR：错误TS2339：属性'componen 实例”在类型“ MatBottomSheetRef”上不存在。

感谢您的帮助

Answer 1

从Angular Material复制：与底部工作表组件共享数据。

如果要将某些数据传递给底部工作表，则可以使用data属性来实现：

const bottomSheetRef = bottomSheet.open(HobbitSheet, {
  data: { names: ['Frodo', 'Bilbo'] },
});

之后，您可以使用MAT_BOTTOM_SHEET_DATA注入令牌访问注入的数据：

import {Component, Inject} from '@angular/core';
import {MAT_BOTTOM_SHEET_DATA} from '@angular/material';

@Component({
  selector: 'hobbit-sheet',
  template: 'passed in {{ data.names }}',
})
export class HobbitSheet {
  constructor(@Inject(MAT_BOTTOM_SHEET_DATA) public data: any) { }
}

注意：角材料的版本为v7.0.3

检查一下： Sharing data with the bottom sheet component

Answer 2

componentInstance属性仅适用于使用ComponentFactoryResolver方法创建并使用ViewContainerRef插入DOM的动态组件。

根据Angular Material Doc，dialog.open返回模型弹出窗口的引用。 https://material.angular.io/components/dialog/api

这可能对某人有用。我需要在底页上添加一张小桌子，以便在@YenYees答案上进行扩展：

import {Component, Inject} from '@angular/core';
import {MatBottomSheet, MatBottomSheetRef} from '@angular/material';
import {MAT_BOTTOM_SHEET_DATA} from '@angular/material';
@Component({
  selector: 'bottom-sheet-overview-example',
  templateUrl: 'bottom-sheet-overview-example.html',
  styleUrls: ['bottom-sheet-overview-example.css'],
})
export class BottomSheetOverviewExample {
  constructor(private bottomSheet: MatBottomSheet) {}

 ELEMENT_DATA: PeriodicElement[] = [
  {position: 1, name: 'Hydrogen', weight: 1.0079, symbol: 'H'},
  {position: 2, name: 'Helium', weight: 4.0026, symbol: 'He'},
  {position: 3, name: 'Lithium', weight: 6.941, symbol: 'Li'},
  {position: 4, name: 'Beryllium', weight: 9.0122, symbol: 'Be'}
];

  openBottomSheet(): void {
    this.bottomSheet.open(BottomSheetOverviewExampleSheet, {
  data:  this.ELEMENT_DATA ,
});
  }
}

@Component({
  selector: 'bottom-sheet-overview-example-sheet',
  templateUrl: 'bottom-sheet-overview-example-sheet.html',
  styleUrls: ['bottom-sheet-overview-example-sheet.css'],
})
export class BottomSheetOverviewExampleSheet {
  constructor(@Inject(MAT_BOTTOM_SHEET_DATA) public data: any, private bottomSheetRef: MatBottomSheetRef<BottomSheetOverviewExampleSheet>, ) {}
  displayedColumns: string[] = ["position", "name", "weight", "symbol"];
  dataSource =  this.data;

  openLink(event: MouseEvent): void {
    this.bottomSheetRef.dismiss();
    event.preventDefault();
  }
}
export interface PeriodicElement {
  name: string;
  position: number;
  weight: number;
  symbol: string;
}

使用bottom-sheet-overview-example-sheet.html作为

<mat-table [dataSource]="dataSource" class="mat-elevation-z8">
  <ng-container matColumnDef="position">
    <mat-header-cell *matHeaderCellDef> No. </mat-header-cell>
    <mat-cell *matCellDef="let element"> {{element.position}} </mat-cell>
  </ng-container>
  <ng-container matColumnDef="name">
    <mat-header-cell *matHeaderCellDef> Name </mat-header-cell>
    <mat-cell *matCellDef="let element"> {{element.name}} </mat-cell>
  </ng-container>
  <ng-container matColumnDef="weight">
    <mat-header-cell *matHeaderCellDef> Weight </mat-header-cell>
    <mat-cell *matCellDef="let element"> {{element.weight}} </mat-cell>
  </ng-container>
  <ng-container matColumnDef="symbol">
    <mat-header-cell *matHeaderCellDef> Symbol </mat-header-cell>
    <mat-cell *matCellDef="let element"> {{element.symbol}} </mat-cell>
  </ng-container>
  <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
  <mat-row *matRowDef="let row; columns: displayedColumns;"></mat-row>
</mat-table>
