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>
