Vue3+Ts封装类似el-dialog的对话框组件

 

提供11个字段对dialog组件进行控制：

• modelValue: 对话框显示隐藏控制,

• width: 控制对话框的宽度,

• height：控制对话框的高度,

• top: 控制对话框个距离顶部的距离,

• title: 控制对话框的标题,

• appendToBody: 是否将对话框添加至body,

• closeOnClickModal: 是否点击遮罩层关闭抽屉,

• showConfirm: 是否显示确认按钮,

• showCancel: 是否显示取消按钮,

• cancelText: 取消按钮的文本,

• confirmText: 确认按钮的文本

dialog.vue代码如下

<template>
	<teleport v-if="appendToBody" to="body">
		<transition name="dialog-fade">
			<div v-show="visible" class="dialog-overlay" :class="customClass" @click.self="handleCloseModal">
