2. Template use

Introduce the template file

Use the template file with is. The name data when using the template definition is used for the data in the loop. If "..." means, you can tile out all the data in the item, so you don't need to write "item.xx" in the template, just write the attributes in the item directly. You need to use the template's 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>
