2. Template use

Introduce the template file

Use the template file with is. The name data when using the template definition is inside the loop. If the data is represented by "...", you can tile out all the data in the item. In this way, you don't need to write "item.xx" in the template. You can just write the attributes in the item directly. You need to use template. Program wxml file

<import src="post-item/post-item-template.wxml" />
<view>
 <block wx:for="{{postList}}" wx:for-item="item">
   <template is="postItem" data="{{...item}}" />
 </block>
</view>

wxss file

@import 'post-item/post-item-template.wxss';
