用法

¥Usage

import { useScreenOrientation } from '@vueuse/core'

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

要锁定方向，你可以将 OrientationLockType 传递给 lockOrientation 函数：

¥To lock the orientation, you can pass an OrientationLockType to the lockOrientation function:

import { useScreenOrientation } from '@vueuse/core'

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

lockOrientation('portrait-primary')

然后再次解锁，如下：

¥and then unlock again, with the following:

unlockOrientation()

接受的方向类型为 "landscape-primary"、"landscape-secondary"、"portrait-primary"、"portrait-secondary"、"any"、"landscape"、"natural" 和 "portrait" 之一。

¥Accepted orientation types are one of "landscape-primary", "landscape-secondary", "portrait-primary", "portrait-secondary", "any", "landscape", "natural" and "portrait".
