Vue3中element-plus全局使⽤Icon图标的过程详解⽬录
1、安装图标库
2、注册
3、在组件中直接使⽤
4、在el-menu组件中动态使⽤
总结
Vue项⽬中使⽤Element-plus的Icon图标，包括按钮和动态菜单
1、安装图标库
npm install @element-plus/icons
2、注册
main.ts⽂件中引⼊并注册
import { createApp } from 'vue'
import App from './App.vue'
import ElementPlus from 'element-plus'
import * as ElIcons from '@element-plus/icons'
const app = createApp(App)
for (const name in ElIcons){
appponent(name,(ElIcons as any)[name])
}
app.use(ElementPlus).mount('#app')
3、在组件中直接使⽤
// 结合按钮使⽤
<el-button type="primary" icon="Edit" >编辑</el-button>
<el-button
size="mini"
type="primary"
class="inline-block"
icon="More"
title="详情"
@click="handleDetail(row.id)"
/>
// 结合el-icon使⽤
<el-icon>
<delete />
</el-icon>
4、在el-menu组件中动态使⽤
如果想在渲染菜单时动态使⽤icon图标，需要使⽤动态组件，举个栗⼦：
// 路由⽂件
export const routes: Array<RouteRecordRaw> = [
{
path: '/',
component: Layout,
redirect: 'home',
children: [
{
path: '/home',
component: () => import('@/views/Home.vue'),
vue element admin
name: 'Home',
meta: { title: '⾸页', icon: 'HomeFilled' },
},
],
},
]
// 使⽤el-menu的⽂件
<template>
<div>
<el-scrollbar wrap-class="scrollbar-wrapper">
<el-menu
router
:default-active="activeMenu"
@open="handleOpen"
@close="handleClose"
>
<template v-for="route in menuList" :key="route.path">
<el-menu-item v-if="!route.children" :index="route.path">
<el-icon>
<component :is="a.icon" />
</el-icon>
<span>{{ a.title }}</span>
</el-menu-item>
<el-sub-menu v-else :index="route.path">
<template #title>
<el-icon>
<component :is="a.icon" />
</el-icon>
<span>{{ a.title }}</span>
</template>
<el-menu-item
v-for="subRoute in route.children"
:key="subRoute.path"
:index="subRoute.path"
>
<el-icon>
<component :is="a.icon" />
</el-icon>
<span>{{ a.title }}</span>
</el-menu-item>
</el-sub-menu>
</template>
</el-menu>
</el-scrollbar>
</div>
</template>
<script lang="ts">
import { defineComponent, computed } from 'vue'
import { useRoute } from 'vue-router'
import { routes } from '@/router/index'
export default defineComponent({
setup() {
const route = useRoute()
const activeMenu = computed(() => {
const { meta, path } = route
if (meta.activeMenu) {
return meta.activeMenu
}
return path
})
const menuList = computed(
() => (routes as any).find((item: any) => item.path === '/').children
)
return { activeMenu, menuList }
},
})
</script>
