In javascript I can loop over an array to output my object as shown below.
在javascript中我可以循环一个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);
});
outputs
输出
ones this is one
这是一个
twos this is two
这是两个
threes this is three
三分，这是三
console.log("number 2 - ",myObj[myArr[1]].desc)
console.log("number 2 - ",myObj["two"].desc)
outputs
输出
number 2 - this is two
2号 - 这是两个
number 2 - this is two
2号 - 这是两个
I want to be able to do this in nunjucks as I want to control the order of display from myArr but also want the flexibility to be able to have a single page eg one.html where I can target one specifically eg {{testObj.one.title}}.
我希望能够在nunjucks中执行此操作，因为我想控制myArr的显示顺序，但也希望能够灵活地拥有单个页面，例如one.html，我可以专门针对一个页面，例如{{testObj.one 。标题}}。
How can this be acheived with nunjucks? I have tried the below.
如何通过nunjucks实现这一目标？我试过以下。
-- 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>
My ideal output to get to would be like the below where I can order my display based on myArr but for each item show the contents of their key in myObj
我理想的输出就像下面我可以根据myArr订购我的显示器但是每个项目都显示myObj中其键的内容
<ul>
<li>one - ones</li>
<li>two - twos</li>
<li>three - threes</li>
</ul>
