在node.js中引用带有forEach的JSON对象
在视图中，我想遍历list并呈现所有列表项的resolved_title 。 这是JSON对象。

下面是视图，但我得到body.list.forEach is not a function错误。 我究竟做错了什么？
<% body.list.forEach(function(item) { %> <p><%= item.resolved_title %></p> <% }) %>
list是不是Array是Object和在Object中没有方法forEach ，试试这个
<% Object.keys(body.list).forEach(function(key) { %> <p><%= body.list[key].resolved_title %></p> <% }) %>
但更好的格式化数据在你的控制器，然后通过它来查看，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> <% }) %>
