Looping through a multidimensional array in Handlebars.js
提问by user1179321
I have the server passing back this JSON and I'm not sure how to loop through a 2-dimensional array in Handlebars.
我让服务器传回这个 JSON，但我不确定如何遍历 Handlebars 中的二维数组。
"userSurvey":[[1],[2],[3]]
I know to use {{#each userSurvey}}but then how would I go about do the arrays inside the usersurveyobject?
我知道要使用，{{#each userSurvey}}但是我将如何处理usersurvey对象内部的数组？

You'd have to loop 2 times:
你必须循环2次：
{{#each userSurvey}}
{{#each this}}
{{ this }}
{{/each}}
{{/each}}

In this particular case if you want to render just "123" you can do this:
在这种特殊情况下，如果您只想渲染“123”，您可以这样做：
{{#each userSurvey}}
{{this.[0]}}
{{/each}}
Or even simpler, because arrays automatiaclly transform to strings:
或者更简单，因为数组会自动转换为字符串：
{{#each userSurvey}}
{{this}}
{{/each}}

{{#each Arr}}
{{#each this}}
<label>{{this.[0]}}</label> {{this.[1]}}<br>
{{/each}}
{{/each}}
Here is my simple example to loop array of my arrays :)
这是我循环数组数组的简单示例:)

Use the #with helper for the obj
对 obj 使用 #with 助手
{ catg: [ 'java', 'c', 'c++' ],
quesarray: [ [ 2, 1 ], [ 0, 2, 10, 5, 11, 12 ], [ 7, 5, 3, 8, 0 ] ],
_id: 5d778d52d410984dc4e3e278,
username: '[email protected]' }
if you want to access the array quesarray index wise do this
如果你想访问数组 quesarray 索引明智地这样做
{{#each qset}}
{{#with quesarray}}
{{[2]}}
{{/with}}
{{/each}}
and output will be 7, 5, 3, 8, 0
输出将是 7, 5, 3, 8, 0
