对于新手们来说，如何写一个可以多用的组件，还是有点难度的，组件如何重用，如何传值这些在实际使用中，是多少会存在一些障碍的，所以今天特意写一个最常用的模态框组件提供给大家，希望能帮助到您！

Modal.vue组件
<template> <!-- 过渡动画 --> <transition name="modal-fade"> <!-- 关闭模态框事件 和 控制模态框是否显示 --> <div class="modal-backdrop" @click="$emit('closeModal')" v-show="show"> <div class="modal"> <img class="img" :src="imgadress" alt=""> <div class="modal-body" id="modalDescription"> <li></li> <!-- 状态提示文字的插槽 --> <slot name="status">{{statusText}}</slot> <li></li> </div> <!-- 模态框内容文字 可有可无 --> <div class="modal-content" v-if="contentText"> {{contentText}} <span v-if="IDList" v-for="item in IDList" :key="item.id">{{item.payMoney}} <i>{{item.yuan}}</i> </span> </div> <ul> <!-- 模态框按钮 可选单个确定按钮 和 两个确定、取消按钮 --> <!-- 单个确定按钮 --> <li v-if="alert" :class="buttonBackground" @click.stop="$emit('button')">确定</li> <!-- 确定和取消按钮 --> <li v-else class="confirm"> <div>取消</div> <div :class="buttonBackground" @click.stop="$emit('confirm')">{{sure}}</div> </li> </ul> </div> </div> </transition></template><script>export default { name:'modal', // 通过 props 传值 props: { imgadress:String, title:String, //标题文字 show:{ //显示取消 type:Boolean, default:false }, statusText:String, //状态文字 contentText:String, //描述文字 IDList:Array, //ID 列表 payMoney:Number, yuan:String, buttonBackground:String, //按钮背景色 alert:String, //判断一个还是两个按钮 sure:String, //第二个按钮的提示文字 }, data(){ return{ closemodal:"close", // isModalVisible:false, // 确定和取消按钮的两种颜色 red:'redBackground', blue:'blueBackground' } }, methods:{ // 关闭模态框事件 close(){ this.$emit('close') }, }}</script><style lang="scss" scoped> .modal-backdrop { position: fixed; top: 0; right: 0; bottom: 0; left: 0; background-color: rgba(0,0,0,.3); display: flex; justify-content: center; align-items: center; z-index: 12; .modal { background-color: #fff; box-shadow: 2px 2px 20px 1px; overflow-x:auto; display: flex; flex-direction: column; width: 11.8rem; position: relative; border-radius: 0.2rem; .img{ width: 3.6rem; height: 3.6rem; margin: 0.8rem 4.1rem; } .modal-header{ padding: 0.6rem 4.1rem; width: 3.6rem; height: 3.6rem; box-sizing: border-box; .img{ width: 100%; height: 100%; } div{ width: 100%; height: 100%; background: #000; } } .modal-body{ width: 100%; height: 0.48rem; padding: 0rem 1.6rem; margin-bottom: 0.8rem; box-sizing: border-box; display: flex; justify-content: space-between; align-items: center; li{ width: 2rem; height: 0.04rem; background: #eeeee5; } } .modal-content{ width: 100%; // height: 0.6rem; margin-bottom: 0.8rem; text-align: center; color: #34304B; span{ color: #32B8B9; i{ color: #4F4F4F; } } } ul{ li{ width: 100%; height: 1.52rem; line-height: 1.52rem; text-align: center; color: #fff; font-size: 0.56rem; letter-spacing: 0.4rem; } .confirm{ display: flex; div:nth-child(1){ flex: 1; background: #DEDEDE; color: #BCBBBF; } div:nth-child(2){ flex: 1; color: #fff; } } } .blueBackground{ background: #21A6DF; } .redBackground{ background: #FF4046; } } }/* 动画 */.modal-fade-enter,.modal-fade-leave-active{ opacity: 0;}.modal-fade-enter-active, .modal-fade-leave-active{ transition: opacity 0.5s ease;}</style>新建一个index.js文件，在其中全局引入组件，全局引入之后，就不用在每个调用的组件里面单独引入了，可以直接使用
import Modalfrom "./Modal.vue";const components = { install: function (Vue) { Vue.component('Modal', Modal); }}//导出组件export default components;Index.vue中调用
<template> <div class="index"><!-- 提交成功模态框 --> <Modal ref="Modal" :imgadress="imgadress" v-show="isModalVisible" statusText="提交成功" @closeModal="closeModal" contentText="Index.vue" :IDList="IDList" :buttonBackground="red" sure="确定" @confirm="confirm" > <!-- :payMoney="payMoney" yuan="元" --> </Modal> <button @click="showModel">支付成功模态框</button> </div></template><script>export default { name: 'Index', data(){ return{ // 模态框 imgadress:require('./../../assets/img/success.png'), isModalVisible:false, show: false, showToast: false, thisIndex:0, green:'green', blue:'', red:'', IDList:[ {payMoney:23456,yuan:'、'}, {payMoney:23456,yuan:'、'}, {payMoney:23456,yuan:'、'}, {payMoney:23456,yuan:'、'}, {payMoney:23456,yuan:'、'}, {payMoney:23456,yuan:'、'}, {payMoney:23456,yuan:'、'}, ], payMoney:99, } }, methods:{ // 提示模态框 showModel(){ this.isModalVisible = true; this.blue = this.$refs.Model.blue this.red = this.$refs.Model.red }, closeModal(){ this.isModalVisible = false }, confirm(){ console.log(11111111111); }, }}</script>效果如图

如果只需要一个确定按钮，只需要在调用的时候，这么写就好了
<template> <div class="index"><!-- 提交成功模态框 --> <Modal ref="Modal" :imgadress="imgadress" v-show="isModalVisible" statusText="提交成功" @closeModal="closeModal" contentText="Index.vue" :IDList="IDList" :buttonBackground="blue" @button="closeModal" sure="确定" alert="1" > </Modal> <button @click="showModel">支付成功模态框</button> </div></template>
如图

可能并不是特别完美，如果您发现有缺点，还请不吝赐教！
