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！
懒癌患者直接复制粘贴即可
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 -->

.modal-fade-enter,.modal-fade-leave-active{
opacity: 0;
}
.modal-fade-enter-active, .modal-fade-leave-active{

}</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！
