Question

我想我可能有配置问题。循环遍历一个对象数组时出错。这是错误。正在将对象数组加载到视图中，它们看起来是正确的。它只是＆＃34; repeat.for＆＃34;那个爆炸了。

Unhandled promise rejection Error: Incorrect syntax for "for". The form is: "$local of $items" or "[$key, $value] of $items".

视图模型

import {HttpClient} from 'aurelia-http-client';

export class App {
  constructor() {
  this.http = new HttpClient();
  this.adverts = [];
 }
 activate() {
  return this.http.get('http://localhost/BackEnd/api/adverts')
    .then(response => {
      this.adverts = response.content;
      console.log(this.adverts);
    });
  }
}

Answer 1

repeat.for="advert of adverts"必须为float f[4]
