uniapp 时间轴
先上图看图说话
时间轴的轴线可以居中分两边，也可以像上图一样。
上代码：
<view class="content"> <time-line ref="timeline" location="left"></time-line> </view> <script> import timeLine from '../../components/xuan-timeLine/xuan-timeLine.vue' export default { components:{ timeLine }, data() { return { time:0, isclick:true, }; }, onLoad() { }, onPageScroll() { if(this.isclick){ this.timer(); this.$refs.timeline.getScroll(); } }, onReady() { }, methods: { timer(){ if(this.time>0){ this.isclick=false; this.time--; setTimeout(this.timer,1) } else{ this.isclick=true; this.time=10 } } } }; </script>
xuan-timeLine.vue代码
