vue组件模态框实现方式

// 组件代码

<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>
