# Templates

WXML provides templates, in which you can define code snippets and then call them in different places.

# Defining a Template

Use the name property to specify the name of the template. Then, define a code snippet in <template/>. For example:

<!--
  index: int
  msg: string
  time: string
-->
<template name="msgItem">
  <view>
    <text> {{index}}: {{msg}} </text>
    <text> Time: {{time}} </text>
  </view>
</template>

# Using the Template

Use the is property to declare the template to be used. Then, pass the data needed by the template. For example:

<template is="msgItem" data="{{...item}}"/>

Page({
  data: {
    item: {
      index: 0,
      msg: 'this is a template',
      time: '2016-09-15'
    }
  }
})

The is property can use Mustache syntax to dynamically determine the template to be rendered:

<template name="odd">
  <view> odd </view>
</template>
<template name="even">
  <view> even </view>
</template>

<block wx:for="{{[1, 2, 3, 4, 5]}}">
  <template is="{{item % 2 == 0 ? 'even' : 'odd'}}"/>
</block>

# Template Scope

Templates have their own scopes. They can only use the data passed by data and the <wxs /> module defined in the file defined by the template.
