可自定义设置以下属性：
- 标题（title），string | slot
- 内容（content），string | slot
- 宽度（width），默认640px
- 高度（height），默认480px
- 是否允许切换全屏，允许后右上角会出现一个按钮（switchFullscreen），默认false
- 取消按钮文字（cancelText），默认‘取消’
- 确认按钮文字（okText），默认‘确定’
- 是否显示底部按钮（footer），默认true
- 对话框水平居中还是固定高度水平居中（center），默认true
- 固定高度水平居中时，距顶部高度（top），默认 100px
- 加载中（loading），默认false
效果如下图所示：（整体样式模仿ant-design-vue Modal，同时阴影覆盖浏览器窗口）
①创建组件Dialog.vue：
<template>
<transition>
<div class="m-dialog-mask" v-show="visible" @click.self="onBlur">
<div :class="['m-dialog', center ? 'relative-hv-center' : 'top-center']" :style="`width: ${dialogWidth}; height: ${dialogHeight}; top: ${!center ? top + 'px':'50%'}`">
<div class="m-dialog-content" :class="{loading: loading}">
<div class="m-spin-dot" v-show="loading">
<span class="u-dot-item"></span>
<span class="u-dot-item"></span>
