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",

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>
