引用template代码

<view wx:for="{{items.children}}" wx:key="id" wx:for-index="cindexs" wx:for-item="items">
  <template is="CommentItem" data="{{item,items,cindexs,cindexs}}"></template>
</view>

template代码如下

<template name="CommentItem">
    <--省略部分-->
    <block wx:if="{{items.children}}">
        <view wx:for="{{items.children}}" wx:key="id" wx:for-index="cindexs" wx:for-item="items">
            <template is="CommentItem" data="{{item,items,cindexs,cindexs}}"></template>
        </view>
    </block>
</template>

其中嵌套部分无法正常显示数据，不知道是哪里出现了问题？

===========================================================

目前解决方法是写多个<template>，修改名字：

<template name="CommentItem">
  <--省略部分-->
  <block wx:if="{{items.children}}">
        <view wx:for="{{items.children}}" wx:key="id" wx:for-index="cindexs" wx:for-item="items">
            <template is="CommentItem1" data="{{item,items,cindexs,cindexs}}"></template>
        </view>
    </block>
</template>


<template name="CommentItem1">
  <--省略部分-->
  <block wx:if="{{items.children}}">
        <view wx:for="{{items.children}}" wx:key="id" wx:for-index="cindexs" wx:for-item="items">
            <template is="CommentItem2" data="{{item,items,cindexs,cindexs}}"></template>
        </view>
    </block>
</template>


<template name="CommentItem2">
  <--省略部分-->
  <block wx:if="{{items.children}}">
        <view wx:for="{{items.children}}" wx:key="id" wx:for-index="cindexs" wx:for-item="items">
            <template is="CommentItem3" data="{{item,items,cindexs,cindexs}}"></template>
        </view>
    </block>
</template>

<--以此类推-->

源码如下：

<template name="CommentItem">
    <view class="comment-header">
        <view class="comment-header-left" catchtap="userTap" data-uid="{{items.user}}">
            <image class="comment-avatar" src="{{items.user_avatar}}">
            </image>
            <view class="comment-user-date">
                <text>{{items.user_nickname}}</text>
                <text>{{items.create_time}}</text>
            </view>
        </view>
        <view class="comment-header-right">
            <view>{{filters.toFix(items.like_count)}}</view>
            <image data-id="{{items.id}}" data-cmtindex="{{cindex}}" data-cmtindexs="{{cindexs}}" bindtap="tapCommentslike" src="/image/heart-fill.png" wx:if="{{items.is_like}}">
            </image>
            <image data-id="{{items.id}}" data-cmtindex="{{cindex}}" data-cmtindexs="{{cindexs}}" bindtap="tapCommentslike" src="/image/heart-line.png" wx:else></image>
            <text wx:if="{{items.user == item.current_user_id}}" data-id="{{items.id}}" data-cmtindex="{{cindex}}" data-cmtindexs="{{cindexs}}" bindtap="tapDeleteComments">删除</text>
        </view>
    </view>
    <view class="comment-content" bindtap="tapComment" data-id="{{item.id}}" data-reply="{{items.user_nickname}}" data-userid="{{items.user}}">
        <view class="commentconent">
            <view class="contentinfo">
                <block wx:if="{{item.user != items.user}}">
                    回复<text>{{item.user_nickname}}</text>：
                </block>
                <block wx:if="{{items.content != null}}">
                    {{items.content}}
                </block>
            </view>
        </view>
        <image wx:if="{{items.image != null && items.image != ''}}" class="img-list" lazy-load='{{true}}' catchtap="previewImgFunc" data-list="{{items.imgList}}" data-src="{{items.image}}" mode="aspectFill" src="{{items.image}}"></image>
    </view>
    <block wx:if="{{items.children}}">
        <view wx:for="{{items.children}}" wx:key="id" wx:for-index="cindexs" wx:for-item="items">
            <template is="CommentItem" data="{{item,items,cindexs,cindexs}}"></template>
        </view>
    </block>
</template>
