uniapp中scroll-view实现自动滚动到最底部的方法

<template>
	<view>
		<scroll-view class="scroll-view" :style="{height:scrollViewHeight+'px'}" :scroll-y="true" :scroll-top="scrollTop" :scroll-with-animation="true">
				<block v-for="(item,index) in images" :key="index">
					<image class="item" :src="item.src" mode="aspectFill"></image>
				</block>
		</scroll-view>
	</view>
</template>
<script>
	export default {
		data() {
			return {
				images:[],
				scrollTop:0,//滚动条位置
				scrollViewHeight:300,//滚动视图的高度
				//...
			};
		},
		//...
	}
</script>
