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 -->

 {{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>

 },
 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;

 .img{

 }
 .modal-header{

/* 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
