Vue 頁面加載數據之前增加 `loading` 動畫
創建組件
1、新建 .vue
文件: src -> components -> laoding -> index.vue
2、編輯 index.vue
文件
<template> <div class="loading"></div> </template> <script> export default { name: "loading" } </script> <style scoped> .loading { position: fixed; left: 20%; top: 20%; background: url('../../assets/images/load2.gif') center center no-repeat ; width: 50vw; height: 50vh; z-index: 1000; } </style>
使用組件
通過自定義一個變量
需要在全局的
isLoading
初始化為
true
,在數據請求成功之后將變量改為
false
,在
template
中通過變量來控制是否顯示隱藏,使用
vue
自帶的
過渡效果 增加用戶體驗
css
中加入過渡需要的樣式 globle.css
.fade-enter, .fade-leave-active { opacity: 0; } .fade-enter-active, .fade-leave-active { transition: opacity 0.5s; }
.vue
文件使用代碼示例片段
<el-table-column prop="salechnl" label="銷售渠道" width="200" align="center"></el-table-column> <el-table-column prop="riskname" label="險種名稱" width="200" align="center"></el-table-column> </el-table> <!-- 分頁 --> <!-- <div align="right" style="margin-top: 20px;margin-right:245px">--> <!-- <el-pagination--> <!-- background--> <!-- @size-change="handleSizeChange"--> <!-- @current-change="handleCurrentChange"--> <!-- :current-page.sync="currentPage"--> <!-- :page-sizes="pageCount"--> <!-- :page-size="5"--> <!-- layout="sizes, prev, pager, next, jumper,total"--> <!-- :total="count"--> <!-- ></el-pagination>--> <!-- </div>--> <transition name="fade"> <loading v-if="isLoading"></loading> </transition> </div> </div> </template>
