vue3全局引入element-plus后使用 Message 消息提示

import ElementPlus from 'element-plus'
const app = createApp(App)
app.use(ElementPlus).mount('#app')

<script setup>
import { getCurrentInstance, onMounted } from 'vue'
const { proxy } = getCurrentInstance()
onMounted(() => {
  proxy.$message.success('123')
})
</script>

使用confirm的方式：proxy.$confirm()
