自定义组件嵌套组件 wx:for item 作用域出错怎么办 - WXOPEN Club

json 数据：

"[[{"name":1,"value":""},{"name":2,"value":""},{"name":3,"value":""}],[{"name":4,"value":[{"name":1,"value":[{"name":1,"value":""},{"name":2,"value":""},{"name":3,"value":""}]},{"name":5,"value":[{"name":1,"value":""},{"name":2,"value":""},{"name":3,"value":""}]},{"name":6,"value":[{"name":1,"value":""},{"name":2,"value":""},{"name":3,"value":""}]}]}],[{"name":7,"value":""},{"name":8,"value":""},{"name":9,"value":""}]]"

组件 wxml：

<view class="question-all-box" wx:for="{{testQuestionList}}" wx:for-item="item1" wx:for-index="index1">

<view class="question-type-name" wx:if="{{!item1.questionlevel}}">{{item.structureName}}</view>

<view class="clearfix" wx:for="{{item1.exerciseStructureVos}}" wx:for-item="item2" wx:for-index="index2">

<view class='margin-bottom-20' class='red pull-left' wx:if="{{!item2.exerciseStructureVos.length}}"

wx:for="{{item2}}" wx:for-item="item3" wx:for-index="index3">

<text>{{item3.orderInType}}</text>

</view>

<view class='margin-bottom-20' class='coral pull-left' wx:if="{{item2.exerciseStructureVos.length}}">

<text>{{item2.orderInType}}</text>

<markErrorModule testQuestionList="{{item2}}"></markErrorModule>

</view>

定义个组件然后组件中再嵌套这个组件时 wx:for 循环时在 <markErrorModule testQuestionList="{{item2}}"></markErrorModule> 嵌套组件循环时出错了 item的作用域出错。
