Question

我正在观看新波士顿的教程，我已经逐行检查，我看不出我的代码是如何不同的。我在这个页面中收到了一个意外的令牌错误。

当我在foreach中的fucntion（item）中的项目之后删除时，它会显示意外的令牌{。所以我不确定从这一点开始。我错过了一些小事吗？

编辑：我在代码中添加了我在页面上获得的错误，因为它很长时间才能发表评论。

EDIT2：添加了header.ejs

header.ejs

<a href="/">Home</a> |
<a href="/about">About</a> |
<a href="#">Link 3</a>

Answer 1

解决了：

import {IUser} from './user.ts';
import {Document, Schema, Model} from 'mongoose';

// mixing in a couple of interfaces
interface IUserDocument extends IUser,  Document {}

// mongoose, why oh why '[String]' 
// TODO: investigate out why mongoose needs its own data types
let userSchema: Schema = new Schema({
  userName  : String,
  password  : String,
  firstName : String,
  lastName  : String,
  email     : String,
  activated : Boolean,
  roles     : [String]
});

// interface we want to code to?
export interface IUserModel extends Model<IUserDocument> {/* any custom methods here */}

// stumped here
export class User {
  constructor() {}
}

Answer 2

您在循环（<%=）上使用echo（forEach），但每次循环（item.categoryName）时都没有输出：

<%= videodata.categories.forEach(function(item) {  %>
  <li><% item.categoryName %></li>
<% }); %>

我认为你应该交换它们，所以你在项目中使用<%=，而不是在循环中。

<% videodata.categories.forEach(function(item) {  %>
  <li><%= item.categoryName %></li>
<% }); %>

Answer 3

我认为您在以下字符串中忘记了“=”：

 <li><%= item.categoryName %></li>
