@0xD800 差不多是这样的

<script lang="ts" setup>
import axios from 'axios';
import { ElLoading } from 'element-plus'
import { onMounted } from 'vue';
let loadingInstance:any = null

function getData() {
let res:any = axios.post('xxx')
if (res && res.success) {
loadingInstance.close()
} else {
//报错提示
loadingInstance.close()
}
}
onMounted(() => {
loadingInstance = ElLoading.service({fullscreen: true})
//请求数据
getData()
})
</script>
