WeChat Mini Program Tutorial WXML

WXML

WXML (WeiXin Markup Language) is a set of tag languages ​​designed by MINA. Combined with basic components and event systems, it can build the structure of the page.

Use the following simple examples to see what capabilities WXML has:

Data binding

<!--wxml-->  
<text> {{message}} </view>  
// page.js  
Page({  
 data: {  
 message: &#39;Hello MINA!&#39;  
 }  
})

List rendering

<!--wxml-->  
<view wx:for-items="{{array}}"> {{item}} </view>  
// page.js  
Page({  
 data: {  
 array: [1, 2, 3, 4, 5]  
 }  
})

Conditional rendering

<!--wxml-->  
<view wx:if="{{view == &#39;WEBVIEW&#39;}}"> WEBVIEW </view>  
<view wx:elif="{{view == &#39;APP&#39;}}"> APP </view>  
<view wx:else="{{view == &#39;MINA&#39;}}"> MINA IS NOT APP </view>  
// page.js  
Page({  
 data: {  
 view: &#39;MINA&#39;  
 }  
})

Template

<!--wxml-->  
<template name="staffName">  
 <view>  
 FirstName: {{firstName}}, LastName: {{lastName}}  
 </view>  
</template>  
  
<template is="staffName" data="...staffA"></template>  
<template is="staffName" data="...staffB"></template>  
<template is="staffName" data="...staffC"></template>  
// page.js  
Page({  
 data: {  
 staffA: {firstName: &#39;Hulk&#39;, lastName: &#39;Hu&#39;},  
 staffB: {firstName: &#39;Shang&#39;, lastName: &#39;You&#39;},  
 staffC: {firstName: &#39;Gideon&#39;, lastName: &#39;Lin&#39;}  
 }  
})

Event

<view bindtap="add"> {{count}} </view>  
Page({  
 data: {  
 count: 1  
 },  
 add: function(e) {  
 this.setData({  
  data: this.data.count + 1  
 })  
 }  
})
