如何使用vue slot创建一个模态框的实例代码

<div class="common-mask" v-if="visible">
 <slot name="head"></slot>
 <slot name="body"></slot>
 <slot name="foot"></slot>
 </div>

<style scoped lang='scss'>
 .common-mask {
 position: fixed;
 top: 0;
 bottom: 0;
 left: 0;
 right: 0;
 background: rgba($color: #000000, $alpha: 0.75);
 display: flex;
 justify-content: center;
 align-content: center;
 z-index: 4;
 }
</style>

<Vue-Modal :visible="visible">
 <div slot="head">head</div>
 <div slot="body">body</div>
 <div slot="foot">
 <button class="common-btn" @click="close">Close</button>
 </div>
 </Vue-Modal>

<template>
<div>
 <div class="dialog-modal"> <!-- 根元素，z-index 需要高于父容器其他元素 -->
  <div class="dialog-wrapper" @click="onClose" v-show="isShow"></div> <!-- 加载一个具有透明度的背景，使根元素透明，子元素会继承该透明度 -->
  <transition name="drop">
    <div class="dialog-container" v-show="isShow"> <!-- 模态框容器，z-index 需要高于背景 -->
      <span class="close-btn" @click="onClose">x</span>
      <slot>
        <p>hello</p>
      </slot>
    </div>
  </transition>
 </div>
</div>
</template>
<script>
  export default {
    props: {
      isShow:{
        type: Boolean,
        default: false
      }
    },
    methods: {
      onClose(){
        this.$emit('on-close');
      }
    }
  }
</script>
<style>
.drop-enter-active {
 transition: all .5s;
}
.drop-leave-active {
 transition: all .3s;
}
.drop-enter {
 transform: translateY(-500px);
}
.drop-leave-active {
 transform: translateY(-500px);
}  
 
  .dialog-modal{
    position: absolute;
    z-index: 5;
  }
  .dialog-wrapper
  {
    position: fixed;
    height: 100%;
    width: 100%;
    z-index: 5;
    top: 0;
    left: 0;
    bottom: 0;
    right: 0;
   
  }
  .dialog-wrapper{
    background-color: #eee;
    opacity: .9;
  }
  .dialog-container{
    position: fixed;
    z-index:80;
    top: 10%;
    left: 25%;
    width: 50%;
    /* margin: 0 auto; */
    background-color: #eee;
    border-radius: 3px;
    box-shadow: 0 5px 15px rgba(0,0,0,.5);
  }
  span.close-btn{
    padding: 0 5px;
    float: right;
    cursor: pointer;
    font-size: 18px;
    font-weight: bold;
  }
</style>

//导入模态对话框
import modal from './plugins/dialog'
// 在使用组件
<modal></modal>

<modal @on-close="closeThis('isShowLog')":is-show='isShowLog'><login></login></modal>
