<template>
	<view class="zPopup_show" v-if="style_show"
		:class="mode=='center'?(show?'zPopup_show_center openAnimation':'zPopup_show_center closeAnimation'):mode=='bottom'?(show?'zPopup_show_bottom  openAnimation':'zPopup_show_bottom  closeAnimation'):''"
		@tap.stop="maskClose?colosePopue():()=>{}">
		<view class="zSlotViews"
			:class="mode=='bottom'?(show?'zSlotViews_bottom_open  ':'zSlotViews_bottom_close  '):''" @tap.stop="()=>{}">
			<view class="zSlotView">
				<image class="colseIcon" src="" mode="aspectFit" @tap.stop="colosePopue"></image>
				<!-- 插槽内容可以自定义 -->
				<slot name="center"></slot>

	</view>
</template>

<script>
	export default {

		//show  主要控制动画效果
		//mode   设置方向弹出
		// maskClose  是否可以通过 点击遮罩层来关闭 弹窗

					//为true是开启动画，动画效果不用延迟出现
					//为false是关闭动画，动画效果先关闭 再进行整个弹窗的关闭，不会出现回显数据消失
