我需要從子組件獲取數據。我的孩子組件有流行的形式。我如何將全部細節傳遞給父組件。 我父組件TS文件是如何將角色2中的值從子元素傳遞給父元素?
import { Component, OnInit } from '@angular/core';
import {MdDialog, MdDialogRef} from '@angular/material';
@Component({
selector: 'app-vehicle-relocate',
templateUrl: './vehicle-relocate.component.html',
styleUrls: ['./vehicle-relocate.component.css'],
})
export class VehicleRelocateComponent implements OnInit {
lat: number = 11.074529;
lng: number = 78.003917;
zoom: number = 14;
ngOnInit() {
}
selectedOption: string;
constructor(public dialog: MdDialog) {}
openDialog() {
let dialogRef = this.dialog.open();
dialogRef.afterClosed().subscribe(result => {
this.selectedOption = result;
});
}
}
我的孩子部件是在父組件
import { Component, OnInit, Input } from '@angular/core';
import {MdDialog, MdDialogRef} from '@angular/material';
@Component({
selector: 'app-relocate-form',
templateUrl: './relocate-form.component.html',
styleUrls: ['./relocate-form.component.css']
})
export class RelocateFormComponent implements OnInit {
constructor(public dialogRef: MdDialogRef<RelocateFormComponent>) {}
@Input() title:string;
ngOnInit() {
}
}
它會幫忙嗎? https://github.com/angular/material2/blob/master/src/demo-app/dialog/dialog-demo.ts –
哪一個是兒童組件? –
