Common Patterns
Example 1 (javascript):
WeixinJSBridge.invoke('imagePreview', {
current: 'http://inews.gtimg.com/newsapp_bt/0/1693121381/641',
urls: [ // 所有图片的URL列表,数组格式
'https://img1.gtimg.com/10/1048/104857/10485731_980x1200_0.jpg',
'https://img1.gtimg.com/10/1048/104857/10485726_980x1200_0.jpg',
'https://img1.gtimg.com/10/1048/104857/10485729_980x1200_0.jpg'
]
}, function(res) {
console.log(res.err_msg)
})
Example 2 (javascript):
wx.previewImage({
current: 'https://img1.gtimg.com/10/1048/104857/10485726_980x1200_0.jpg',
urls: [ // 所有图片的URL列表,数组格式
'https://img1.gtimg.com/10/1048/104857/10485731_980x1200_0.jpg',
'https://img1.gtimg.com/10/1048/104857/10485726_980x1200_0.jpg',
'https://img1.gtimg.com/10/1048/104857/10485729_980x1200_0.jpg'
],
success: function(res) {
console.log(res)
}
})
Example 3 (html):
<!-- /components/index.wmxl -->
<view class="index">{{prop}}</view>
Example 4 (js):
// /components/index.js
Component({
properties: {
prop: {
type: String,
value: 'index.properties'
},
},
})
Example 5 (css):
/* /components/index.wxss */
.index {
color: green;
}
Example 6 (json):
{
"nickName": "Band",
"gender": 1,
"language": "zh_CN",
"city": "Guangzhou",
"province": "Guangdong",
"country": "CN",
"avatarUrl": "http://wx.qlogo.cn/mmopen/vi_32/1vZvI39NWFQ9XM4LtQpFrQJ1xlgZxx3w7bQxKARol6503Iuswjjn6nIGBiaycAjAtpujxyzYsrztuuICqIM5ibXQ/0"
}
Example 7 (json):
{
"openId": "OPENID",
"nickName": "NICKNAME",
"gender": GENDER,
"city": "CITY",
"province": "PROVINCE",
"country": "COUNTRY",
"avatarUrl": "AVATARURL",
"unionId": "UNIONID",
"watermark":
{
"appid":"APPID",
"timestamp":TIMESTAMP
}
}
Example 8 (js):
wx.cloud.callFunction({
name: 'myFunction',
data: {
weRunData: wx.cloud.CloudID('xxx'), // 这个 CloudID 值到云函数端会被替换
obj: {
shareInfo: wx.cloud.CloudID('yyy'), // 非顶层字段的 CloudID 不会被替换,会原样字符串展示
}
}
})
Example 9 (html):
<scroll-view type="list" scroll-y>
<view> a </view>
<view> b </view>
<view> c </view>
</scroll-view>
Example 10 (html):
<scroll-view type="list" scroll-y>
<virtual-comp>
<view> a </view>
<view> b </view>
<view> c </view>
</virtual-comp>
</scroll-view>

Key Concepts
App Lifecycle
App({
onLaunch(options) {
// Mini Program initialized
},
onShow(options) {
// Mini Program shown
},
onHide() {
// Mini Program hidden
},
globalData: {
userInfo: null
}

Page({
data: {
message: 'Hello World'
},
onLoad(options) {
// Page loaded
},
onShow() {
// Page shown
},
onReady() {
// Page ready
},
onHide() {
// Page hidden
},
onUnload() {
// Page unloaded
}
})
WXML Data Binding
<view>{{message}}</view>
<view wx:if="{{condition}}">Conditional</view>
<view wx:for="{{array}}" wx:key="id">{{item}}</view>
Event Handling
<button bindtap="handleTap">Click Me</button>
Page({
handleTap(e) {
console.log(e)
}
})
