useMediaQuery
响应式的 媒体查询。一旦您创建了一个 MediaQueryList 对象,您可以检查查询结果或在结果变化时接收通知。
Demo
isLargeScreen: false
prefersDark: false
使用方法
js
import { useMediaQuery } from '@vueuse/core'
const isLargeScreen = useMediaQuery('(min-width: 1024px)')
const isPreferredDark = useMediaQuery('(prefers-color-scheme: dark)')
Server Side Rendering and Nuxt
If you are using useMediaQuery
with SSR enabled, then you need to specify which screen size you would like to render on the server and before hydration to avoid an hydration mismatch
js
import { breakpointsTailwind, useMediaQuery } from '@vueuse/core'
const isLarge = useMediaQuery(
'(min-width: 1024px)',
{ ssrWidth: 768 } // Will enable SSR mode and render like if the screen was 768px wide
)
console.log(isLarge.value) // always false because ssrWidth of 768px is smaller than 1024px
onMounted(() => {
console.log(isLarge.value) // false if screen is smaller than 1024px, true if larger than 1024px
})
Alternatively you can set this up globally for your app using provideSSRWidth
