useScreenOrientation

响应式屏幕方向 API (Screen Orientation API)。它为 Web 开发者提供了用户当前屏幕方向的信息。

Demo

使用

import { useScreenOrientation } from '@vueuse/core'

const {
  isSupported,
  orientation,
  angle,
  lockOrientation,
  unlockOrientation,
} = useScreenOrientation()

要锁定屏幕方向，你可以向 lockOrientation 函数传入一个 OrientationLockType：

import { useScreenOrientation } from '@vueuse/core'

const {
  isSupported,
  orientation,
  angle,
  lockOrientation,
  unlockOrientation,
} = useScreenOrientation()

lockOrientation('portrait-primary')

然后再次解锁，使用以下方法：

unlockOrientation()

接受的方向类型是以下之一："landscape-primary"、"landscape-secondary"、"portrait-primary"、"portrait-secondary"、"any"、"landscape"、"natural" 和 "portrait"。
