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
