Anchor 锚点
通过锚点，您可以很快找到当前页面上信息内容的位置。
基础用法
最简单的用法。
vue
<template>
<el-anchor :offset="70">
<el-anchor-link :href="`#${locale['basic-usage']}`">
{{ locale['Basic Usage'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['horizontal-mode']}`">
{{ locale['Horizontal Mode'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['scroll-container']}`">
{{ locale['Scroll Container'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['anchor-api']}`">
{{ locale['Anchor API'] }}
<template #sub-link>
<el-anchor-link :href="`#${locale['anchor-attributes']}`">
{{ locale['Anchor Attributes'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['anchor-events']}`">
{{ locale['Anchor Events'] }}
</el-anchor-link>
</template>
</el-anchor-link>
</el-anchor>
</template>
<script lang="ts" setup>
import { computed } from 'vue'
import anchorLocale from '../../.vitepress/i18n/component/anchor.json'
import { useLang } from '~/composables/lang'
const lang = useLang()
const locale = computed(() => anchorLocale[lang.value])
</script>隐藏源代码
水平模式
水平排列的锚点
TIP
水平模式不支持sub-link槽位
vue
<template>
<el-anchor :offset="70" direction="horizontal">
<el-anchor-link :href="`#${locale['basic-usage']}`">
{{ locale['Basic Usage'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['horizontal-mode']}`">
{{ locale['Horizontal Mode'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['scroll-container']}`">
{{ locale['Scroll Container'] }}
</el-anchor-link>
</el-anchor>
</template>
<script lang="ts" setup>
import { computed } from 'vue'
import anchorLocale from '../../.vitepress/i18n/component/anchor.json'
import { useLang } from '~/composables/lang'
const lang = useLang()
const locale = computed(() => anchorLocale[lang.value])
</script>隐藏源代码
滚动的容器
自定义滚动区域，使用 offset props 可以设置锚点滚动偏移。 监听link-click事件并阻止浏览器的默认行为，然后它不会改变历史。
vue
<template>
<div>
<el-row>
<el-col :span="18">
<div
style="
height: 30px;
width: 70%;
background: #000;
position: absolute;
top: 0;
left: 0;
color: #fff;
"
>
Fixed Top Block
</div>
<div ref="containerRef" style="height: 300px; overflow-y: auto">
<div
id="part1"
style="
height: 300px;
background: rgba(255, 0, 0, 0.02);
margin-top: 30px;
"
>
part1
</div>
<div
id="part2"
style="
height: 300px;
background: rgba(0, 255, 0, 0.02);
margin-top: 30px;
"
>
part2
</div>
<div
id="part3"
style="
height: 300px;
background: rgba(0, 0, 255, 0.02);
margin-top: 30px;
"
>
part3
</div>
</div>
</el-col>
<el-col :span="6">
<el-anchor
:container="containerRef"
direction="vertical"
type="default"
:offset="30"
@click="handleClick"
>
<el-anchor-link href="#part1" title="part1" />
<el-anchor-link href="#part2" title="part2" />
<el-anchor-link href="#part3" title="part3" />
</el-anchor>
</el-col>
</el-row>
</div>
</template>
<script setup lang="ts">
import { ref } from 'vue'
const containerRef = ref<HTMLElement | null>(null)
const handleClick = (e: MouseEvent) => {
e.preventDefault()
}
</script>隐藏源代码
锚点链接变化
监听锚点链接变化
vue
<template>
<el-anchor :offset="70" @change="handleChange">
<el-anchor-link :href="`#${locale['basic-usage']}`">
{{ locale['Basic Usage'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['horizontal-mode']}`">
{{ locale['Horizontal Mode'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['scroll-container']}`">
{{ locale['Scroll Container'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['anchor-api']}`">
{{ locale['Anchor API'] }}
<template #sub-link>
<el-anchor-link :href="`#${locale['anchor-attributes']}`">
{{ locale['Anchor Attributes'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['anchor-events']}`">
{{ locale['Anchor Events'] }}
</el-anchor-link>
</template>
</el-anchor-link>
</el-anchor>
</template>
<script setup lang="ts">
import { computed } from 'vue'
import anchorLocale from '../../.vitepress/i18n/component/anchor.json'
import { useLang } from '~/composables/lang'
const lang = useLang()
const locale = computed(() => anchorLocale[lang.value])
const handleChange = (href: string) => {
console.log(`anchor change: ${href}`)
}
</script>隐藏源代码
下划线类型
设置`type="underline"更改为下划线类型
vue
<template>
<el-anchor type="underline" :offset="70">
<el-anchor-link :href="`#${locale['basic-usage']}`">
{{ locale['Basic Usage'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['horizontal-mode']}`">
{{ locale['Horizontal Mode'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['scroll-container']}`">
{{ locale['Scroll Container'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['anchor-api']}`">
{{ locale['Anchor API'] }}
<template #sub-link>
<el-anchor-link :href="`#${locale['anchor-attributes']}`">
{{ locale['Anchor Attributes'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['anchor-events']}`">
{{ locale['Anchor Events'] }}
</el-anchor-link>
</template>
</el-anchor-link>
</el-anchor>
</template>
<script lang="ts" setup>
import { computed } from 'vue'
import anchorLocale from '../../.vitepress/i18n/component/anchor.json'
import { useLang } from '~/composables/lang'
const lang = useLang()
const locale = computed(() => anchorLocale[lang.value])

固定模式
使用 affix 组件来固定住页面中的锚点。
vue
<template>
<el-affix :offset="60">
<el-anchor :offset="70" style="width: 300px">
<el-anchor-link :href="`#${locale['basic-usage']}`">
{{ locale['Basic Usage'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['horizontal-mode']}`">
{{ locale['Horizontal Mode'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['scroll-container']}`">
{{ locale['Scroll Container'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['anchor-api']}`">
{{ locale['Anchor API'] }}
<template #sub-link>
<el-anchor-link :href="`#${locale['anchor-attributes']}`">
{{ locale['Anchor Attributes'] }}
</el-anchor-link>
<el-anchor-link :href="`#${locale['anchor-events']}`">
{{ locale['Anchor Events'] }}
</el-anchor-link>
</template>
</el-anchor-link>
</el-anchor>
</el-affix>
</template>
<script lang="ts" setup>
import { computed } from 'vue'
import anchorLocale from '../../.vitepress/i18n/component/anchor.json'
import { useLang } from '~/composables/lang'
const lang = useLang()
const locale = computed(() => anchorLocale[lang.value])
