The example in this article summarizes the way in which WeChat applet implements data transfer to nested templates. Share it with everyone for your reference, the details are as follows:

1. When the data called by the template template is in a single form:

indexTemplate template:

<import src="../lookAndCollect-template/lookAndCollect-template.wxml" />
<template name="indexTemplate">
 <view class="user-info">
  <image class="avatar" src="{{avatar}}"></image>
  <text class="name">{{name}}</text>
  <text class="date">{{date}}</text>
 </view>
 <view class="news">
  <text class="news-title">{{title}}</text>
  <image class="news-img" src="{{newsImg}}"></image>
  <text class="news-content">{{content}}</text>
 </view>
 <template is="reviewAndCollect" data="{{review,look}}"></template>
</template>

lookAndCollect template:

<template name="lookAndCollect-template">
 <view class="lookAndCollect-template">
  <view class="lookAndCollect-template-review">
   <image src="/smallApp/images/icon/view.png"></image>
   <text>{{look}}</text>
  </view>
  <view class="lookAndCollect-template-look">
   <image src="/smallApp/images/icon/chat.png"></image>
   <text>{{collect}}</text>
  </view>
 </view>
</template>

The reference of indexTemplate template in index.wxml:

  <block wx:for="{{newsData}}" wx:for-item="newsItem">
   <view class="item">
    <template is="indexTemplate" data="{{...newsItem}}" />
   </view>
  </block>

index.wxml corresponding index.js writing method:

var newsDataList = require("../index-data.js");
Page({
  data: {
  },
  onLoad: function (option) {
    this.setData({
      newsData: newsDataList.dataList
    });
  }
})

Use a single form of data in the template:

var news_data = [
  {
    listId: "0",
    avatar: "/smallApp/images/avatar/1.png",
    name: "我是大猫猫",
    date: "16分钟前",
    title: "搞事情?法国招聘新特工 会汉语成必备条件",
    newsImg: "/smallApp/images/post/crab.png",
    content: "是的，你没看错，据法国《费加罗报》报道，法国境外安全总局（DGSE）欲在2019年前招募600名新特工，而且新的特工必须年轻、有高等文凭，会多国语言，并且熟悉电脑与互联网。",
    review: "0",
    look: "30"
  },
  {
    listId: "1",
    avatar: "/smallApp/images/avatar/2.png",
    name: "风口上的猪",
    date: "1天前",
    title: "顺丰控股上市次日盘中涨停 离首富差4个涨停",
    newsImg: "/smallApp/images/post/bl.png",
    content: "根据之前借壳方鼎泰新材发布的公告，该公司定增完成后，第一大股东将变更为深圳明德控股发展有限公司(简称“明德控股”)，持股比例为64.58%，后4名分别为宁波顺达丰润投资管理合伙企业(有限合伙)…",
    review: "100",
    look: "380"
  }
];
module.exports = {
  dataList: news_data
}

If you need to pass in multiple data in a nested template, you can separate each data with a comma.

2. The calling method when nested template calls include object objects:

The data review and look used in the template are in the form of objects When presenting:

var news_data = [
  {
    listId: "0",
    avatar: "/smallApp/images/avatar/1.png",
    name: "我是大猫猫",
    date: "16分钟前",
    title: "搞事情?法国招聘新特工 会汉语成必备条件",
    newsImg: "/smallApp/images/post/crab.png",
    content: "是的，你没看错，据法国《费加罗报》报道，法国境外安全总局（DGSE）欲在2019年前招募600名新特工，而且新的特工必须年轻、有高等文凭，会多国语言，并且熟悉电脑与互联网。",
    reviewAndCollect {
      review: "0",
      look: "30"
    }
  },
  {
    listId: "1",
    avatar: "/smallApp/images/avatar/2.png",
    name: "风口上的猪",
    date: "1天前",
    title: "顺丰控股上市次日盘中涨停 离首富差4个涨停",
    newsImg: "/smallApp/images/post/bl.png",
    content: "根据之前借壳方鼎泰新材发布的公告，该公司定增完成后，第一大股东将变更为深圳明德控股发展有限公司(简称“明德控股”)，持股比例为64.58%，后4名分别为宁波顺达丰润投资管理合伙企业(有限合伙)…",
    reviewAndCollect {
      review: "120",
      look: "300"
    }
  }
];
module.exports = {
  dataList: news_data
}

indexTemplate template

<import src="../lookAndCollect-template/lookAndCollect-template.wxml" />
<template name="indexTemplate">
 <view class="user-info">
  <image class="avatar" src="{{avatar}}"></image>
  <text class="name">{{name}}</text>
  <text class="date">{{date}}</text>
 </view>
 <view class="news">
  <text class="news-title">{{title}}</text>
  <image class="news-img" src="{{newsImg}}"></image>
  <text class="news-content">{{content}}</text>
 </view>
 <template is="reviewAndCollect" data="{{reviewAndCollect}}"></template>
</template>

lookAndCollect template:

<template name="lookAndCollect-template">
 <view class="lookAndCollect-template">
  <view class="lookAndCollect-template-review">
   <image src="/smallApp/images/icon/view.png"></image>
   <text>{{reviewAndCollect.look}}</text>
  </view>
  <view class="lookAndCollect-template-look">
   <image src="/smallApp/images/icon/chat.png"></image>
   <text>{{reviewAndCollect.collect}}</text>
  </view>
 </view>
</template>
