I have an error: 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.
src / app / posts / posts.component.ts(21,11)中的错误:错误TS2696:“对象”类型可分配给极少数其他类型。 Did you mean to use the > 'any' type instead?
你的意思是使用>'any'类型吗? Type 'Object' is missing the following properties from type 'any[]': length, pop, push, concat, and 26 more.
类型'对象'缺少类型'any []'的以下属性:length,pop,push,concat和26。 src/app/posts/posts.component.ts(32,33): error TS2339: Property 'id' does not exist on type 'Object'.
src / app / posts / posts.component.ts(32,33):错误TS2339:属性'id'在类型'Object'上不存在。
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;
}
});
}
}
You need to say the response is of type any to get rid of that error, 您需要说响应是any类型以消除该错误,
this.service.createPost(post)
.subscribe(
(response :any) => {
response is an array but you don't have a value called id. response是一个数组,但您没有名为id的值。 Or its not reaching 'id', you may have multiple ones.
或者它没有达到'id',你可能有多个。
