如何使用小程序API屏幕亮度 -wx.setScreenBrightness ？

[align=center]步骤一[/align]打开微信开发者工具，添加小程序项目，选择小程序文件（文末贴出本次小程序测试文件包）！PS：没有小程序appid不妨申请一个！

 

[align=center]步骤二[/align][align=center]打开index文件夹，配置index.js[/align]

 
贴出代码
//index.js
//获取应用实例
var app = getApp()
Page({
data:{
},
changeScreenLight:function(e){
var that = this;
//滑动拉杆获得值
wx.setScreenBrightness({
value: parseFloat(e.detail.value).toFixed(1)
})
//给屏幕亮度赋值
wx.getScreenBrightness({
success: function(res) {
that.setData({
ScreenBrightness: res.value
})
}
})
}
})[align=center]步骤三[/align][align=center]打开index文件夹，配置index.wxml[/align]

 
<slider min="0" max="1" step="0.1"bindchange="changeScreenLight"/>
