[英]Object literal may only specify known properties, and 'select' does not exist in type 'Settings'
[英]Angular Object literal may only specify know properties and … does not exist in type
我開始使用Angular並遇到錯誤。
... / mocks.ts(9,4):輸入'{“id”:number; “name”:string; “description”:字符串; “inStock”:數字; “價格”:數量; “featu ...”不能分配給'CarPart []類型。對象文字只能指定已知屬性,'carPart'類型中不存在'“featured”'。
我的代碼:
汽車part.ts
export class CarPart {
id: number;
name: string;
description: string;
inStock: number;
price: number;
featured: boolean;
}
mock.ts
import { CarPart } from './car-part';
export const CARPARTS: CarPart[] = [{
"id": 1,
"name": "Super Tires",
"description": "These tires are the very best",
"inStock": 5,
"price": 299.99,
"featured": false //Line 9
},
{
"id": 2,
"name": "Reinforced Shocks",
"description": "Shocks made of kryptonite",
"inStock": 4,
"price": 500.50,
"featured": false
},
{
"id": 3,
"name": "Padded Seats",
"description": "Super soft seats for a smooth ride",
"inStock": 0,
"price": 333.33,
"featured": true
}];
汽車parts.component.ts
import { Component, OnInit } from '@angular/core';
import { CarPart } from './car-part';
import { CARPARTS } from './mock';
@Component({
selector: 'car-parts',
templateUrl: './car-parts.component.html',
styleUrls: ['./car-parts.component.css']
})
export class CarPartsComponent implements OnInit {
constructor() { }
carParts: CarPart[];
totalCarParts(){
let sum = 0;
for(let carPart of this.carParts){
sum += carPart.inStock;
}
return sum;
}
ngOnInit() {
this.carParts = CARPARTS;
}
}
當我從mock.ts和car-part.ts中刪除“精選”時它很好,沒有錯誤。 如果我添加它或任何其他名稱或類型,它將無法正常工作......有人能解釋一下嗎?
我重新啟動了Angular CLI服務器( Ctrl + C > ng服務)。 編譯沒有問題......
證據表明“你試過把它關掉再打開”仍然是有意義的。 感謝時間看Tim和Max的問題
