JQuery简易时间轴功能

2024-06-09 09:06:13 前端知识 前端哥 730 978 我要收藏

场景:需要对某一系列用户的操作进行时间点记录和时间轴展示

参考资料:时间轴网址 —> 对应Git地址
示例
需要用到的JS和CSS:在这里插入图片描述

插件自带功能与使用场景有些许不符,需要改造

1.新增自定义宽度属性:

3.修改部分自己业务需要的css样式,不在这里展开。

详细使用过程

1.定义Html元素(空DIV实体):

    <div class="regionForTimeAxios"style="height:95%;">
        <div id="report_Time_Axios" class="timeline">
            <div class="timeline__wrap" style="height:100%;width: 100%; overflow-x: auto">
                <div class="timeline__items">
				
                </div>
            </div>
        </div>
    </div>

2.构造时间点Html串,并塞入页面中:

 var timeLineHtml = '';
 //时间轴列表数据构造Html
 $.each(dataList, function (io, vo) {
     timeLineHtml += '<div class="timeline__item"><div class="timeline__content"><div class="reportTimeLineToolTip" style="width:170px;padding:2.5px 0;white-space: nowrap;overflow: hidden;text-overflow: ellipsis;"><span>【' + vo.on + '】</span><span>' + convertOpType(vo) + '</span></div><span>' + new Date(vo.time).format('yyyy-MM-dd hh:mm:ss') + '</span></div></div > '
 });
 if (timeLineHtml) {
     //塞入元素
     $('#report_Time_Axios .timeline__wrap .timeline__items').append(timeLineHtml)
     //时间轴渲染
     $('#report_Time_Axios').timeline({
         mode: 'horizontal',
         itemDefaultWidth: 200,
         //更多属性可查看JS
     });
 }

3.页面效果:
在这里插入图片描述
(看起来是左右滑动,实际上中间的轴并没有动)
如果设计到数据切换,渲染新数据前直接清空Div里的内容重新渲染即可。

修改后的JS和CSS文件
