Nunjucks迭代数组中的项目以显示对象中的项目

Question

在JavaScript中，我可以遍历数组来输出我的对象，如下所示。

var myArr = ["one","two","three"] 
var myObj = { 
    "one": { 
    "title": "ones", 
    "desc": "this is one" 
    }, 
    "three": { 
    "title": "threes", 
    "desc": "this is three" 
    }, 
    "two": { 
    "title": "twos", 
    "desc": "this is two" 
    } 
} 

myArr.forEach(function (value) { 
    console.log(myObj[value].title, myObj[value].desc); 
}); 

输出

ones this is one

twos this is two

threes this is three

console.log("number 2 - ",myObj[myArr[1]].desc) 
console.log("number 2 - ",myObj["two"].desc) 

输出

number 2 - this is two

number 2 - this is two

我希望能够做到这一点的nunjucks，我想控制从myArr显示的顺序，但也希望能够灵活地能够有一个页面如one.html哪里我可以针对一个具体的例如{{testObj.one.title}}。

这怎么能与nunjucks达到？我已经尝试了下面。

-- nunjucks -- 
<ul> 
    {% for item in testArr %} 
    <li>{{item}} - {{testObj.one.title}}</li> 
    {% endfor %} 
</ul> 

<ul> 
    {% for obj, item in testObj %} 
     <li>{{ obj }}: {{ item | dump }} - {{ item.title }} - {{ item.desc }}</li> 
    {% endfor %} 
</ul> 

--- output --- 
<ul> 
    <li>one - ones</li> 
    <li>two - ones</li> 
    <li>three - ones</li> 
</ul> 

<ul> 
    <li>one: {"title":"ones","desc":"this is one"} - ones - this is one</li> 
    <li>three: {"title":"threes","desc":"this is three"} - threes - this is three</li> 
    <li>two: {"title":"twos","desc":"this is two"} - twos - this is two</li> 
</ul> 

我的理想输出去会像下面的我在哪里可以订购基于myArr我的显示器，但每个项目显示myObj

<ul> 
    <li>one - ones</li> 
    <li>two - twos</li> 
    <li>three - threes</li> 
</ul> 

Answer 1

<ul> 
    {% for item in myArr %} 
    <li>{{item}} - {{myObj[item].title}}</li> 
    {% endfor %} 
</ul> 

其关键的内容是什么？
