对象和 v-for 的嵌套数组 [英] Nested arrays of objects and v-for

问题描述

好吧，这个问题让我难住了...在显示嵌套的 for 循环数据时遇到了一些麻烦:

{{文件夹名称}}<div v-for="check in folder.checks">{{check.name}}

然后我尝试使用的数据如下所示:

文件夹 [数组]-object [这是一个文件夹"]- 姓名--checks [array] [每个文件夹都有这个数组]---[对象] [实际的检查"对象]-  - [姓名]

外循环工作正常，并返回我期望的数据.但是， check.name 不返回任何内容，并且控制台中没有错误.是否可以像这样进行嵌套的 for 循环?

解决方案

我测试了你的模板，它有效.

 new Vue({el: '#sample',数据: {私人的: {文件夹:[{名称:'文件夹1'，检查: [{名称:'check1.1'}，{名称:'check1.2'}]},{名称:'文件夹2'，检查: [{名称:'check2.1'}，{名称:'check2.2'}]}]}}})

<script src="https://cdn.jsdelivr.net/vue/latest/vue.js"></脚本><div id="样本"><div v-if = "private.folders!=null" v-for="private.folders 中的文件夹">{{文件夹名称}}<div v-for="check in folder.checks">{{check.name}}

Well, this problem has me stumped... Having a bit of trouble getting nested for-loop data to show up:

<div v-if = "private.folders!=null" v-for="folder in private.folders">
{{folder.name}}
    <div v-for="check in folder.checks">
        {{check.name}}
    </div>
</div>

And then the data that I'm trying to use looks like this:

folders [Array]
-object [this is a single 'folder']
--name
--checks [array] [each folder has this array]
---[object] [the actual 'check' object]
----[name]

The outer loop works just fine, and returns the data I expect. However, check.name doesn't return anything, and there are no errors in the console. Is it possible to do nested for-loops like this?

解决方案

I tested you template, it's works.

 new Vue({
  el: '#sample',
  data: {
    private: {
      folders : [{
          name : 'folder1',
          checks : [
            { name : 'check1.1' },
            { name : 'check1.2' }
          ]
        },
        {
          name : 'folder2',
          checks : [
            { name : 'check2.1' },
            { name : 'check2.2' }
          ]
        }
      ]
    }
  }
})

<script src="https://cdn.jsdelivr.net/vue/latest/vue.js"></script>
<div id="sample">
  <div v-if = "private.folders!=null" v-for="folder in private.folders">
  {{folder.name}}
      <div v-for="check in folder.checks">
          {{check.name}}
      </div>
  </div>
</div>
