我想知道你是否可以帮忙。我正在关注这门类(class)https://www.udemy.com/the-complete-angular-master-class/learn/lecture/7441148#questions
我有一个错误:
ERROR in src/app/posts/posts.component.ts(21,11): error TS2696: The 'Object' type is assignable to very few other types. Did you mean to use the > 'any' type instead? Type 'Object' is missing the following properties from type 'any[]': length, pop, push, concat, and 26 more. src/app/posts/posts.component.ts(32,33): error TS2339: Property 'id' does not exist on type 'Object'.
import { BadInput } from './../common/bad-input';
import { NotFoundError } from './../common/not-found-error';
import { AppError } from './../common/app-error';
import { PostService } from './../services/post.service';
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'app-posts',
templateUrl: './posts.component.html',
styleUrls: ['./posts.component.css']
})
export class PostsComponent implements OnInit {
posts: any[];
constructor(private service: PostService) {}
ngOnInit() {
this.service.getPosts()
.subscribe(
response => {
this.posts = response
});
}
createPost(input: HTMLInputElement) {
let post : any = { id: null, title: input.value };
input.value = '';
this.service.createPost(post)
.subscribe(
response => {
post['id'] = response.id;
this.posts.splice(0, 0, post);
console.log(response);
},
(error: AppError) => {
if (error instanceof BadInput) {
//this.form.setErrors(error.originalError)
} else {
throw error;
}
});
}
updatePost(post) {
this.service.updatePost(post)
.subscribe(
response => {
console.log(response);
});
}
deletePost(post) {
this.service.deletePost(99999)
.subscribe(
response => {
let index = this.posts.indexOf(post);
this.posts.splice(index, 1);
},
(error: AppError) => {
if (error instanceof NotFoundError) {
console.log(error);
} else {
throw error;
}
});
}
}
最佳答案
您需要说明响应的类型为any 才能消除该错误,
this.service.createPost(post)
.subscribe(
(response :any) => {
关于angular - 类型 'id' 上不存在属性 'Object',我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/56292980/
