小编kas*_*hen的帖子

我正在使用材料2版本2.0.0-beta.12.我需要调整材质Modal的位置.我按照这个答案来做到这一点./sf/answers/3096708961/由于MdDialog现在不可用,我使用了{MatDialog,MatDialogRef,MAT_DIALOG_DATA}.

constructor(public dialog: MatDialog,public dialModRef:MatDialogRef<any>) {}

import {Component, Inject} from '@angular/core';
import {MatDialog, MatDialogRef, MAT_DIALOG_DATA} from 
'@angular/material';

@Component({
   selector: 'dialog-overview-example',
   templateUrl: 'dialog-overview-example.html'
})
export class DialogOverviewExample {

   animal: string;
   name: string;

   constructor(public dialog: MatDialog,public 
   dialModRef:MatDialogRef<any>) {}

   openDialog(): void {
       let dialogRef = this.dialog.open(DialogOverviewExampleDialog, {
        width: '500px',
        data: { name: this.name, animal: this.animal }
   });

   dialogRef.afterClosed().subscribe(result => {
      console.log('The dialog was closed');
      this.animal = result;
   });
 }
}

@Component({
   selector: 'dialog-overview-example-dialog',
   templateUrl: 'dialog-overview-example-dialog.html',
})
export class DialogOverviewExampleDialog …
