Vue development - bottom navigation bar component

Not much to say, go directly to the code BottomNav.vue:

<template>
	<div class="footer">
		<div v-for='(item,index) of items' :class='[item.cls,{on:index === idx}]' @click="$router.push(item.push)">
			<img :src="index===idx?item.iconSelect:item.icon">
			<p :class="['colorChange',{on:index===idx}]" >{{item.name}}</p>
		</div>

	</div>
</template>

<script type="text/javascript">
	
	export default{
		props:['idx'],
		data(){
			return {
				items:[{
					cls:"home",
					name:"Home",
					push:"/home",
					icon:"../static/home.png",
					iconSelect:"../static/home_select.png"
				},
				{
					cls:"shares",
					name:"Stock",
					push:"/shares",
					icon:"../static/home.png",
					iconSelect:"../static/home_select.png"
				},
				{
					cla:"community",
					name:"Community",
					push:"/community",
					icon:"../static/home.png",
					iconSelect:"../static/home_select.png"
				},
				{
					cla:"mine",
					name:"my",
					push:"/mine",
					icon:"../static/home.png",
					iconSelect:"../static/home_select.png"
				}]
			}
		}
	}

</script>

:src="index===idx?item.iconSelect:item.icon" Judge whether it is the current page through the code, and select the unreasonable picture

@click="$router.push(item.push) Jump to each page

Style:

.footer{
	display: flex;
	position: absolute;
	left: 0;
	bottom: 0;
	box-sizing: border-box;
	height: 6rem;
	background: #909090;
	width: 100%;}
	div{
		flex: 1;
		font-size: 30px;
	}
	div img{
		width: 30px;
		height: 30px;
	}
	div p{
		color:black;
	}
	.on{
		color: red;
	}
