基于vue的悬浮碰撞窗口（用于打广告的）组件

由于项目需要改写了一个悬浮碰撞弹窗组件

<template>
	<div class="floatLayer">
		<a class="close-btn" href="javascript:;" @click.stop="closeView">×</a>
		<img  :src="json.src" alt="">
	</div>
</template>
<script>
	export default{
		data(){
			return{
				object: [],
				left:0,
				top:0,
				interval:30,
				distance:2,
				directionX:1,
				directionY:1,
				zIndex:100,
				target:"_blank",
				cursor:"pointer",
				i:0
			}
		},
		props:['json'],
		mounted(){
			this.init(this.json);
		},
		methods:{
			closeView(){
				this.$emit("closeView");
			},
			init(json){
				var obj = document.querySelector(".floatLayer");
				//自定义
				obj.left=parseInt(json.left || this.left);
				obj.top = parseInt(json.top || this.top);
        obj.interval = json.interval || this.interval;
        obj.distance = json.distance || this.distance;

          }
        }
        if (!json.noHoverPause) {
            obj.onmouseover = function () {
                clearInterval(this.t);
            }
            obj.onmouseout = function () {

      float(index) {

调用方式（加上了多个悬浮碰撞弹窗）

<float-view v-if="showView" :json="json" @closeView="closeView"></float-view>
<float-view v-if="showView2" :json="json2" @closeView="closeView2"></float-view>

数据来源模拟的
json:{
        src: 'https://www.ssdfz.net/ImageFiles/20180419130336830.jpg',
        url: 'http://www.baidu.com',
        left: 100,
        top: 400,
        directionX: 1,
        directionY: 1,
        distance: null,
        interval: null,
        target: null,
        zIndex: null,
         null,
        height: null,
        noHoverPause: null, //鼠标经过时不停止，为true时不停止
        cursor: null,
      },

json2:{
src: 'https://www.ssdfz.net/ImageFiles/20180424095347234.jpg',
url: 'http://www.baidu.com',
left: 0,
top: 0,
directionX: 1,
directionY: 1,
distance: null,
interval: null,
target: null,
zIndex: null,
null,
height: null,
noHoverPause: null, //鼠标经过时不停止，为true时不停止
cursor: null,
},

父组件的基本操作

父组件控制显示隐藏
data(){
  return{
      showView:true,
      showView2:true,
  }      
},
methods:{
    closeView(val){
      this.showView=false;
    },
    closeView2(val){
      this.showView2=false;
    },
}
