此处我更新了 account.component.ts account.component.html 和 updateAccountAttributes.html 文件。
在 account.component.html 文件中，我在下面的行中添加了 opendialog（行）方法...
**<mat-row *matRowDef="let row; columns: displayedColumns1;" (click)="openDialog(row)"> </mat-row>**
我在 account.component.ts 文件中调用了此方法，并在控制台中显示了行数据。
使用 updateAccountAttributes.html 文件打开此对话框...
我能够在对话框中获取数据......但是如何在弹出视图中访问特定元素数据....
请帮忙解决这个问题............
