如果我们的Vue项目中没有用到任何UI框架的话,为了更好的用户体验,肯定会用到loading和toast。那么我们就自定义这两个组件吧。
1、Toast组件
首先,在common下新建global文件夹,存放我们的toast.vue和toast.js两个文件(当然文件的具体位置你可以自行安排)。
(1). toast.vue
<template lang="html"> <div v-if="isShowToast" class="toast-container" @touchmove.prevent> <!-- 这里content为双花括号 --> <span class="loading-txt">{content}</span> </div></template><script>export default { data () { return { isShowToast: true, content: '' } }}</script><!-- Add "scoped" attribute to limit CSS to this component only --><style scoped>.toast-container { position: fixed; top: 0; left: 0; width: 100%; height: 100%; background: rgba(255, 255, 255, 0.1);}.toast-msg { position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); width: 60%; padding: 35px; border-radius: 10px; font-size: 28px; line-height: 36px; background: #eee; color: #666;}</style>
(2). toast.js
import Vue from 'Vue'import ToastComponent from './Toast.vue'const Toast = {}let showToast = false // 存储loading显示状态let toastNode = null // 存储loading节点元素const ToastConstructor = Vue.extend(ToastComponent)Toast.install = function (Vue, options) { // 参数 var opt = { duration: '1200' } for (var property in options) { opt[property] = options[property] } Vue.prototype.$toast = function (tips, type) { if (type === 'hide') { toastNode.isShowToast = showToast = false } else { if (showToast) { // 如果toast还在,则不再执行 return } toastNode = new ToastConstructor({ data: { isShowToast: showToast, content: tips } }) toastNode.$mount() // 挂在实例,为了获取下面的toastNode.$el document.body.appendChild(toastNode.$el) toastNode.isShowToast = showToast = true setTimeout(function () { toastNode.isShowToast = showToast = false }, opt.duration) } }; ['show', 'hide'].forEach(function (type) { Vue.prototype.$toast[type] = function (tips) { return Vue.prototype.$toast(tips, type) } })}export default Toast
然后,我们需要把写好的组件在 /src/main.js 中引用一下。
import Toast from './components/common/global/toast'Vue.use(Toast)
最后,怎么使用呢?只需在要用的地方this.$toast.show('hello world')
2、Loading组件
loading组件只需要照着toast组件搬过来,稍微改下就可以了。
首先,在common下新建global文件夹,存放我们的loading.vue和loading.js两个文件。
(1). loading.vue
<template lang="html"> <div v-if="isShowLoading" class="loading-container"> <div class="loading-box"> <img class="loading-img" :src="require('../../../assets/images/loading.png')"> <!-- 这里content为双花括号 --> <span class="loading-txt">{content}</span> </div> </div></template><script>export default { data () { return { isShowLoading: false, content: '' } }}</script><!-- Add "scoped" attribute to limit CSS to this component only --><style scoped>.loading-container { display: flex; justify-content: center; align-items: center; position: fixed; top: 0; left: 0; width: 100%; height: 100%; background: rgba(0, 0, 0, 0); z-index: 1000;}.loading-box { display: flex; flex-direction: column; justify-content: center; align-items: center; width: 150px; height: 150px; border-radius: 10px; background: #e5e5e5;}.loading-img { width: 70px; height: 70px; animation: rotating 2s linear infinite;}@keyframes rotating { 0% { transform: rotate(0deg); } 100% { transform: rotate(1turn); }}.loading-txt { display: flex; justify-content: center; align-items: center; font-size: 24px; color: #666;}</style>
