1-封装模态框组件Mydialog (样式可以自己写)

<template>
 <transition name="modal" tag="div">
  <div class="modal" v-show="visible" transition="fade">
   <div class="modal-dialog">
    <div class="modal-content">
     <!--头部-->
     <div class="modal-header">
      <slot name="header">
       <!-- <p class="title">{{modal.title}}</p> -->
      </slot>
      <a @click="close(0)" class="xd xd-close" href="javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></a>
     </div>
     <!--内容区域-->
     <div class="modal-body">
      <slot name="body">
      </slot>
     </div>
     <!--尾部,操作按钮-->
     <div class="modal-footer">
      <slot name="footer">
       <slot name="button" class="footer">>
        <a v-if="modal.showCancelButton" href="javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="button" :class="modal.cancelButtonClass" @click="close">{{modal.cancelButtonText}}</a>
        <a v-if="modal.showConfirmButton" href="javascript:void(0)" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="button" :class="modal.confirmButtonClass" @click="close()">{{modal.confirmButtonText}}</a>
       </slot>
      </slot>
     </div>
    </div>
   </div>
  </div>
  <!-- <div v-show="show" class="modal-backup"></div> -->
 </transition>
</template>

2-使用方法1

页面中引入在进行调用

(1) import Mydialog from '../carrer/mydialog.vue';

(2)引入组件

 components: {
  Mydialog
 }

(3  在html中插入组件

<Mydialog v-show="isShowDialog" :dialog-option="dialogOption" ref="mydialog"></Mydialog>

data中的参数

 showDialog: false,
   dialogOption: {
    text: '欢迎',
    cancelButtonText: '否',
    confirmButtonText: '是',
    isShowCancelButton: ''
  },

methods中 在需要出现弹框时候让其显示就好啦

 showDialog()
   this.dialogOption.text = ` <p>确认拒绝？</p> `;
   this.dialogOption.isShowCancelButton = true
   this.showDialog = true;
   this.$refs.mydialog.confirm().then(() => {
    this.showDialog = false;
    this.refuse(id)
   }).catch(() => {
    this.showDialog = false;
   })
  },

3.使用方法2

因为在项目中经常要使用到，而且每次使用的时候都要带上相同的参数，所以就封装了一个js，（模态框的工具类），使用的时候调用就好了

1)- 新建一个js文件dialogUtil，复制下面的代码就好了

class normalDialog {
 constructor(args) {
  // console.log("args",args);
  this.parent = args.parent;
  this.isShowDialog = args.isShowDialog;
  this.dialogOption = this.parent[args.dialogOption];
  this.mydialog = this.parent.$refs[args.mydialog];
  // console.log("dialogOption=",this.dialogOption);
 }

 showDialog(text, showCancelButton, success, error) {
  console.log("showDialog=="+text);
  this.dialogOption.text = text || "请输入弹框标题";
  let suc = typeof showCancelButton == "function" ? showCancelButton : success;
  let err = typeof showCancelButton == "function" ? success : error;
  if (typeof showCancelButton != "function") {
   this.dialogOption.isShowCancelButton = !!showCancelButton;
  } else {
   this.dialogOption.isShowCancelButton = true;
  }
  this.parent[this.isShowDialog] = true;
  this.confirm(suc, err);
 }

 //弹框回调
 confirm(success, error) {
  let self = this;
  this.mydialog.confirm().then(() => {
   typeof success == "function" && success();
   self.parent[this.isShowDialog] = false;
  }).catch(() => {
   typeof error == "function" && error();
   self.parent[this.isShowDialog] = false;
  })
 }

 toString() {
  // console.log(this.name + " : " + this.age);
 }

}

export default {
 //args：参数， 类型
 creatByType(args, type) {
  type = !!type ? type : 1;

  switch (type) {
   case 1:
    return new normalDialog(args)
    break;
   case 2:
    break
   default:
    break;
  }
 }
}

2) 因为很多页面都用到，所以让他成为全局的（在main中引入就好了），那么别的页面使用就不需要引入了

import dbDiaLogUtil from './assets/js/dialogUtil'
Vue.prototype.$dbDiaLogUtil = dbDiaLogUtil;

3)在使用的时候

页面中引入组件在进行调用

(1) import Mydialog from '../carrer/mydialog.vue';

(2)引入组件

 components: {
  Mydialog
 }

 （3） 在html中插入组件

 <Mydialog v-show="isShowDialog" :dialog-option="dialogOption" ref="mydialog"></Mydialog>

在data（）中用对象的形式

  isShowDialog : false,
   dialogOption:{text: '',cancelButtonText: '否',confirmButtonText: '确认',isShowCancelButton: false},
   dialogNormal:null,

在mounted中进行初始化

this.dialogNormal = this.$dbDiaLogUtil.creatByType({parent:this,isShowDialog:'isShowDialog',dialogOption:'dialogOption',mydialog:'mydialog'});

最后在需要弹框的地方调用，一句代码搞定啦

this.dialogNormal.showDialog('dialog要显示的内容',function(){console.log('成功执行的')} , function(){console.log('失败执行的')})
