我有以下数据对象:
import { Injectable } from '@angular/core';
@Injectable({
providedIn: 'root'
})
export class CheckoutData {
email:string;
firstName:string;
lastName:string;
deliveryMethod: "Standard";
paymentMethod: "Credit Card";
}
我将对象注入到组件的构造函数中并将其记录到控制台:
constructor(
private store: Store<{ checkoutStore; cartState }>,
public checkoutData:CheckoutData
) {
console.log('checkoutData constructor', this.checkoutData)
}
它记录垃圾而不是实例化的数据对象:
checkoutData constructor s {}[[Prototype]]: Object
在我的视图中选择单选按钮而不是在数据对象中存储垃圾:
<div class="form-check">
<input class="form-check-input" type="radio" id="formCheck-3" name="paymentMethod"
[(ngModel)]="checkoutData.paymentMethod" #paymentMethod=ngModel
(change)="saveCheckoutData()"
[value]="paymentMethod">
<label class="form-check-label" for="formCheck-3" style="font-size:
14px;">PayPal</label>
</div>
我只能看到你课堂上的一个拼写错误。
应该是
export class HelloService {
email: string;
firstName: string;
lastName: string;
deliveryMethod = 'Standard'; //typo
paymentMethod = 'Credit Card'; //typo
}
