对于
mdDialog,我如何传入变量？具体来说,如何将Angular服务注入对话框组件？
对于传递变量,您可以从MdDialog.open()方法调用中返回的MdDialogRef实例中获取对话框中打开的组件的实例.
dialogRef = this.dialog.open(PizzaDialog,config) dialogRef.componentInstance.<property_name>
来自github material2 docs的改良比萨饼
@Component({
selector: 'pizza-component',template: `
<button type="button" (click)="openDialog()">Open dialog</button>
`
})
export class PizzaComponent {
constructor(public dialog: MdDialog) { }
openDialog() {
let config = new MdDialogConfig();
let dialogRef:MdDialogRef<PizzaDialog> = this.dialog.open(PizzaDialog,config);
dialogRef.componentInstance.name = "Ham and Pineapple";
dialogRef.componentInstance.size = "Large";
}
}
@Component({
selector: 'pizza-dialog',template: `
<h2>{{name}}</h2>
<p>Size: {{size}}</p>
<button type="button" (click)="dialogRef.close('yes')">Yes</button>
<button type="button" (click)="dialogRef.close('no')">No</button>
`
})
export class PizzaDialog {
name:string;
size:string;
constructor(public dialogRef: MdDialogRef<PizzaDialog>) { }
}
