useBreakpoints

反应式视口断点。

¥Reactive viewport breakpoints.

示例

source

Current breakpoints: []

Active breakpoint:

xs(<640px): false

xs(<=640px): false

sm: false

md: false

lg: false

xl: false

2xl: false

greaterThanBreakPoint: false

用法

¥Usage

import { breakpointsTailwind, useBreakpoints } from '@vueuse/core'

const breakpoints = useBreakpoints(breakpointsTailwind)

const smAndLarger = breakpoints.greaterOrEqual('sm') // sm and larger
const largerThanSm = breakpoints.greater('sm') // only larger than sm
const lgAndSmaller = breakpoints.smallerOrEqual('lg') // lg and smaller
const smallerThanLg = breakpoints.smaller('lg') // only smaller than lg

<script setup lang="ts">
import { useBreakpoints } from '@vueuse/core'

const breakpoints = useBreakpoints({
  mobile: 0, // optional
  tablet: 640,
  laptop: 1024,
  desktop: 1280,
})

// Can be 'mobile' or 'tablet' or 'laptop' or 'desktop'
const activeBreakpoint = breakpoints.active()

// true or false
const laptop = breakpoints.between('laptop', 'desktop')
</script>

<template>
  <div :class="activeBreakpoint">
    ...
  </div>
</template>

预设

¥Presets

• Tailwind：breakpointsTailwind

• Bootstrap v5：breakpointsBootstrapV5

• Vuetify v2：breakpointsVuetifyV2（已弃用：breakpointsVuetify）

  ¥Vuetify v2: breakpointsVuetifyV2 (deprecated: breakpointsVuetify)

• Vuetify v3：breakpointsVuetifyV3

• Ant Design：breakpointsAntDesign

• Quasar v2：breakpointsQuasar

• Sematic：breakpointsSematic

• Master CSS：breakpointsMasterCss

• Prime Flex：breakpointsPrimeFlex

• ElementUI / ElementPlus:breakpointsElement

断点预设故意不自动导入，因为它们不以 use 开头，不具有 VueUse 的范围。它们必须明确导入：

¥Breakpoint presets are deliberately not auto-imported, as they do not start with use to have the scope of VueUse. They have to be explicitly imported:

import { breakpointsTailwind } from '@vueuse/core'
// and so on
