“post”仅指一种类型，但在此处用作值

Question

I am getting errors in this component.ts file at push(post). the error is 'post' only refers to a type, but is being used as a value here.

import { Component } from '@angular/core';
import { post } from './comp/list/list.module';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
spost:post[]=[];

onpostadd(){
  this.spost.push(post);
}
}

this is the model.ts file

export interface post {

  title: string;
  content : string;

}

Answer 1

It is exactly as it says: You're only exporting an interface (which is just a type) post , not an actual value. Therefore you can't use it as a value.

Your onpostadd() probably expects post as an argument that you didn't add.

Also, it's quite common to CamelCase type names, similar to classes, eg use Post instead. This makes it hard to confuse it with lowercase variable names.
