如何使用胡须使用任意键渲染JSON? [英] How to render json with arbitrary keys using mustache?
问题描述
我有一个类似于以下内容的JSON对象:
I have a JSON object that looks like the following:
{
"XXX":{"name":"First"},
"YYY":{"name":"Second"},
....
}
我需要将其呈现为:
<div>
<h1>XXX</h1>
<p>First</p>
</div>
<div>
<h1>YYY</h1>
<p>Second</p>
</div>
....
我将如何使用胡子完成此操作?我面临的问题是我不知道如何引用这些项,因为键名是任意的.
How will I accomplish this using Mustache? The problem I am facing is that I don't know how to reference the items because the key names are arbitrary.
推荐答案
使用您喜欢的JSON解析器将JSON转换为哈希,这将为您提供类似于以下的内容:
Convert the JSON to a hash using your favorite JSON parser, that will give you something that looks like this:
json = {
"XXX" => {"name" => "First"},
"YYY" => {"name" => "Second"},
"ZZZ" => {"name" => "Third"}
}
然后只需将其重新排列为带有已知密钥的小哈希列表:
Then simply rearrange it into a list of little hashes with known keys:
for_mustache = json.keys.inject([ ]) do |a, k|
a.push({ :k => k, :v => json[k]['name']})
a
end
上面可能有更聪明的方法来做到这一点.现在,您将在for_mustache
中拥有一些简单而又常规的内容:
There are probably cleverer ways to do that above. Now you'll have something simple and regular like this in for_mustache
:
[
{ :k => "XXX", :v => "First" },
{ :k => "YYY", :v => "Second" },
{ :k => "ZZZ", :v => "Third" }
]
然后,您可以像处理Mustache中的其他任何哈希数组一样处理该数据结构:
Then you can handle that data structure just like any other array of hashes in Mustache:
{{#for_mustache}}
<div>
<h1>{{k}}</h1>
<p>{{v}}</p>
</div>
{{/for_mustache}}
