微信小程序 使用模板(template)填充列表项、模板中添加列表项(item)点击事件

前言：前一篇文章已经说到了如何使用模板，这里不做赘述。
一、创建一个模板listItem.wmxl的文件，内容如下：里面涉及到的数据有4个：id,path,title,content及绑定了一个点击事件readDetail

<template name='list'>
   <view style="display:flex;flex-direction:row;margin-top:5px;background-color:#e6e6e6" 
      bindtap='readDetail' data-id='{{id}}'>
      <image style="width:40%;height:80px;" src='{{path}}' mode='widthFix'/>
      <view style="display:flex;flex-direction:column;margin-left:10px">
         <text>{{title}}text>
         <text>{{content}}text> 
      view>
   view>
template>

二、在需要使用的地方引入，及数据填充，如下：

<import src='listItem.wxml'/>
<view>
   <view wx:for="{{arrays}}">
      <template is="list" data="{{id:index,path:item.path,title:item.title,content:item.content}}"/>
   view>
view>

三、js文件中的data和点击事件readDetail函数如下：

/**
   * 页面的初始数据
   */
  data: {
     arrays: [{
        id:0,
        path:'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1522750024551&di=2a3059f66cada3c3fcf09ed6fbfa7ff0&imgtype=0&src=http%3A%2F%2Fimgsrc.baidu.com%2Fimgad%2Fpic%2Fitem%2Feaf81a4c510fd9f9a499b16e2f2dd42a2834a42f.jpg',
      title:'大源中央公园',
      content:'大源'},
        {
           id: 1,
           path:'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1522749957085&di=f63a53aa11dc3d2c6ee656ecf26a734e&imgtype=0&src=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fupload%2Fupc%2Ftx%2Fphotoblog%2F1109%2F09%2Fc1%2F8912689_8912689_1315533674830.jpg',
      title:'花园国际',
      content:'花儿'},
        {
           id: 2,
           path: 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1522749957089&di=52d63a22521f4928cefc91097853bae4&imgtype=0&src=http%3A%2F%2Fscimg.jb51.net%2Fallimg%2F140812%2F11-140Q21045523K.jpg',
           title: '大源中央公园',
           content: '大源'
        },
        {

           title: '大源中央公园',
           content: '大源'
        },
        {
           id: 9,
           path: 'https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1522749848720&di=96beca6c27cf406900332cdd7bda8515&imgtype=0&src=http%3A%2F%2Fimgsrc.baidu.com%2Fimage%2Fc0%253Dpixel_huitu%252C0%252C0%252C294%252C40%2Fsign%3Dc5f68d1bb81bb0519b29bb685f02bfd8%2F10dfa9ec8a1363270e51430a9a8fa0ec08fac74f.jpg',
           title: '大源中央公园',
           content: '大源'
        },],
  },

  readDetail: function (e) {//点击列表项函数
     var index = e.currentTarget.dataset.id; //打印可以看到，此处已获取到了对应的id
     console.log('位置：'+index);
  },

实现效果：点击后出现圆圈中的日志
