vue3 loading 等待效果
一、自定义组件 loading.vue
<template> <div class="loading" v-show="msg.show"> <div class="load-box"> <img src="@/assets/img/load.png"> <!--<img src="@/assets/img/loading_white.png">--> <span>{{msg.title}}</span> </div> </div> </template> <script> export default { name: 'loading', props: { msg: Object, } } </script> <style scoped lang="scss"> .loading { width: 100%; height: 100%; position: absolute; top: 0; left: 0; display: flex; justify-content: center; align-items: center; z-index: 9999; .load-box { background-color: rgba(0, 0, 0, .5); width: 100px;height: 100px;border-radius: 5px; box-shadow:0px 1px 15px rgba(0,0,0, .5);color: #fff; display: flex;flex-direction: column;align-items: center; justify-content: center;letter-spacing: .8px; font-size: 13px; img{ width: 30px;margin-bottom: 8px; -webkit-animation:rotate .8s linear infinite; } } } @keyframes rotate{ to{ transform: rotate(360deg); } } </style>
二、utils/loading.js
创建封装js控制显示和隐藏,以及需要显示的文字
import { createApp, reactive } from 'vue' import myLoad from '@/components/Loading/loading.vue' const msg = reactive({ show: false, title: '加载中...' }) const $loading = createApp(myLoad, {msg}).mount(document.createElement('div')) const load = { show(title) { // 控制显示loading的方法 msg.show = true msg.title = title document.body.appendChild($loading.$el) }, hide() { // 控制loading隐藏的方法 msg.show = false } } export { load }
三、页面使用
import { load } from '@/utils/loading.js'; // 在需要使用时调用show方法 // 例如在指定api调用,或者其他耗时操作时打开loading // 不传参默认为 加载中... load.show(); load.show('登录中...'); //在加载完成时关闭 load.hide();
