Reference

WXML provides two file reference methods, import and include.

import

import can use the template defined by the target file in this file, such as:

in item.wxml A template called item is defined in:

<!-- item.wxml -->
<template name="item">
 <text>{{text}}</text>
</template>

If item.wxml is referenced in index.wxml, you can use the item template:

<import src="item.wxml"/>
<template is="item" data="{{text: &#39;forbar&#39;}}"/>

import scope

Import has the concept of scope, that is, it will only import the template defined in the target file, but not the template imported by the target file.
For example: C import B, B import A, the template defined by B can be used in C, and the template defined by A can be used in B, but C cannot use the template defined by A.

<!-- A.wxml -->
<template name="A">
 <text> A template </text>
</template>

<!-- B.wxml -->
<import src="a.wxml"/>
<template name="B">
 <text> B template </text>
</template>

<!-- C.wxml -->
<import src="b.wxml"/>
<template is="A"/> <!-- Error! Can not use tempalte when not import A. -->
<template is="B"/>

include

include can introduce the entire code of the target file out of , which is equivalent to copying to the include location, such as:

<!-- index.wxml -->
<include src="header.wxml"/>
<view> body </view>
<include src="footer.wxml"/>

<!-- header.wxml -->
<view> header </view>

<!-- footer.wxml -->
<view> footer </view>
