這篇文章主要介紹了詳解如何用VUE寫一個多用模態(tài)框組件模版，小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

對于新手們來說，如何寫一個可以多用的組件，還是有點難度的，組件如何重用，如何傳值這些在實際使用中，是多少會存在一些障礙的，所以今天特意寫一個最常用的模態(tài)框組件提供給大家，希望能幫助到您！

Modal.vue組件

<template>
  <!-- 過渡動畫 -->
  <transition name="modal-fade">
    <!-- 關(guān)閉模態(tài)框事件 和 控制模態(tài)框是否顯示 -->
    <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>
          <!-- 狀態(tài)提示文字的插槽 -->
          <slot name="status">{{statusText}}</slot>
          <li></li>
        </div>
        <!-- 模態(tài)框內(nèi)容文字 可有可無 -->
        <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>
          <!-- 模態(tài)框按鈕 可選單個確定按鈕 和 兩個確定、取消按鈕 -->
          <!-- 單個確定按鈕 -->

新建一個index.js文件，在其中全局引入組件，全局引入之后，就不用在每個調(diào)用的組件里面單獨引入了，可以直接使用

import Modalfrom "./Modal.vue";
const components = {
  install: function (Vue) {
    Vue.component('Modal', Modal);
  }
}
//導(dǎo)出組件
export default components;

Index.vue中調(diào)用

<template>
  <div class="index">
<!-- 提交成功模態(tài)框 -->
    <Modal
      ref="Modal"
      :imgadress="imgadress"
      v-show="isModalVisible"
      statusText="提交成功"
      @closeModal="closeModal"
      contentText="Index.vue"
      :IDList="IDList"
      :buttonBackground="red"
      sure="確定"
      @confirm="confirm"
    >
      <!-- :payMoney="payMoney"
      yuan="元" -->
    </Modal>
    <button @click="showModel">支付成功模態(tài)框</button>

  </div>
</template>
<script>
export default {
  name: 'Index',
  data(){
    return{
      // 模態(tài)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:{
    // 提示模態(tài)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>

效果如圖

如果只需要一個確定按鈕，只需要在調(diào)用的時候，這么寫就好了

<template>
  <div class="index">
<!-- 提交成功模態(tài)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="確定"
      alert="1"
    >
    </Modal>
    <button @click="showModel">支付成功模態(tài)框</button>

  </div>
</template>
