Question

在视图中，我想遍历list并渲染所有列表项的resolved_title。这是JSON对象。

{ status: 1,
  complete: 1,
  list:

以下是视图，但我收到body.list.forEach is not a function错误。我做错了什么？

<% body.list.forEach(function(item) { %>
    <p><%= item.resolved_title %></p>
<% }) %>

Answer 1

list Array不是Object而Object中没有方法forEach，请尝试此操作

<% Object.keys(body.list).forEach(function(key) { %>
    <p><%= body.list[key].resolved_title %></p>
<% }) %>

但更好的格式化控制器中的数据，然后将其传递给视图，就像这样

var titles = Object.keys(body.list).map(function(key)
  return body.list[key].resolved_title;
});

// pass titles to view 

<% titles.forEach(function(title) { %>
    <p><%= title %></p>
<% }) %>

在node.js中引用带有forEach的JSON对象
