uniapp scroll-view 滚动到底部

uniapp yekong

uniapp 开发app时,需要用到评论功能,当我们评论是,需要评论内容滚动到最新的地方,比如滚动到最底部。

<scroll-view id="scrollview" class="list" :scroll-top="scrollTop" :class="{list2:emojiList.lenth>0}" scroll-y
			scroll-with-animation>
			<view id="msglistview">
			</view>
</scroll-view>
scrollToBottom() {
				let that = this
				let query = uni.createSelectorQuery()
				query.select('#scrollview').boundingClientRect()
				query.select('#msglistview').boundingClientRect()
				query.exec((res) => {
					// console.log(res)
					console.log(res)
					//获取所有内部子元素的高度
					//判断子元素高度是否大于显示高度
					if (res[1].height > res[0].height) {
						// 用子元素的高度减去显示的高度就获益获得滚动的高度
						that.scrollTop = res[1].height - res[0].height
					}
				})

			},
			goclose() {
				this.$emit('gethide', 0)
			},
			fasong() {
				var data = {
					'user': 'Jonas gegw',
					'desc': '',
					'num': 90,
					'time': moment().format("YYYY-MM-DD HH:mm:ss"),
					'like': false
				}
				data.desc = this.textareaVal
				this.list.push(data)
				this.textareaVal = ''
				this.$nextTick(() => {
					this.scrollToBottom()
				})

			},

滚动到底部

scrollToButtom() {
				const query = uni.createSelectorQuery().in(this);
				let nodesRef = query.select('#message-scroll');
				nodesRef
					.boundingClientRect(res => {
						this.$nextTick(() => {
							//进入页面滚动到底部
							this.scrollTop = res.height;
						});
					})
					.exec();
			},
