使用vue完成点击鼠标产生小心心特效

先上源码
背景颜色很不好看，如需修改请#lovesBgc{}更改这个里边的就好

<template>
	<div>
		<div id="lovesBgc"></div>
		<!-- 点击biubiubiu小心心  start-->
		<div v-for="(item,index) in loves" v-bind:key="index"  v-bind:ref="loves[index].count"  class="img"
		v-bind:style="item.top+item.left+item.scale+item.opacity" style="  float: left;">
			<div class="left"  v-bind:style="item.childBgc"></div>
			<div class="right" v-bind:style="item.childBgc"></div>
			<div class="under" v-bind:style="item.childBgc"></div>
			<div class="text"> {{text[loves[index].textIndex]}}</div>
		</div>
		<!-- 点击biubiubiu小心心  stop-->
		
		<!-- 上升气泡   start-->
		<div class="bubbels">
			<div v-for="(item,index) in bubbles" v-bind:key="index" class="bubble"
				v-bind:style="item.color+item.width+item.height+item.left+
				item.delay+item.duration">
			</div>
		</div>
		<!-- 上升气泡   stop-->
	</div>
</template>

</style>

使用方法：
在要使用的页面引用这个页面，如上边的名字为background.vue

<script> 
 import background from './background.vue'
  export default {
	    components: {background},
		methods: {
			createLoves(){
				this.$refs.background.createLoves(event)
			},
			removeSmallHert(){
				this.$refs.background.removeSmallHert()
			}
		}
    }	
</script>

在页面使用

<div id="login" v-on:mousedown.left="createLoves($event)" v-on:mouseup="removeSmallHert">
		<background ref="background"></background>	
</div>

css样式

#login{
	position: absolute;
	top: 0;
	left: 0;
	width: 100%;
	height: 100%;
}

ok大功告成，作者也是初学，如果有什么不对的可以提出来我们一起探讨，如果运行不出来可以留言，一般情况来说完成以上几步就可以了
