vue 实现modal

本文只是作为练习弹出框，弹框内部的东西需要进行自定义添加，主要对更新，删除，新建 ，提示四种弹框进行实现，例子中只是简单的组件应用

Modal.vue文件

<template>
	<div id ="modalPopBox" v-if="innerAriaShow">
		<div class="el-modal-wrapper">
			<div class="el-modal-box">
				<div class="el-modal-header">
					<span class="el-modal-title">{{ariaLabel}}</span>
					<span class="close" @click="closeModal()">x</span>
				</div>
				<div class="el-modal-content">
					<slot name="body"></slot>
				</div>
				<div class="el-modal-btns">
					<slot name="btns"></slot>
				</div>
			</div>
		</div>
	</div>
</template>
<script>
	export default{
		name:'modalPopBox',
		props:{
			ariaLabel:{
				type:String,
				default:'prompt'
			},
			ariaShow:{
				type:Boolean,
				default:false
			},
			itemId:{
				type:Number
			}
		},
		data:function(){
			return {
				innerAriaShow:this.ariaShow,
				updateModal:'',
				deleteModal:'',
				addModal:'',
				promptModal:''
			}
		},
		methods:{
			closeModal:function(){
				this.innerAriaShow = false;
				if(this.ariaLabel=='Update'){
					this.updateModal=false;
					this.$emit('getUpdateModal',this.updateModal);
				}
				if(this.ariaLabel=='Delete'){
					this.deleteModal=false;
					this.$emit('getDeleteModal',this.deleteModal);
				}
				if(this.ariaLabel=='New'){
					this.addModal = false;
					this.$emit('getAddModal',this.addModal);
				}
				if(this.ariaLabel=='Prompt'){
					this.promptModal = false;
					this.$emit('getPromptModal',this.promptModal);
				}
			}
		}
	}
</script>
<style>
	#modalPopBox{

        z-index: 9998;
