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">

          <li></li>
        </div>
        <!-- 模态框内容文字 可有可无 -->

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
