本文实例为大家分享了JS实现数据动态渲染竖向步骤条的具体代码，供大家参考，具体内容如下

实现以下效果：

运用的知识点主要是html的伪元素。然后步骤条通过js动态渲染。最后一条数据的状态颜色状态为高亮状态。
直接上代码

html部分：

<ul class="progress_box"> </ul>

css部分：

* { margin: 0; padding: 0; } ul { width: 360px; margin:100px auto; } li { position: relative; padding: 0 21px; list-style: none; height: 54px; border-left: 1px solid #4BACFD; } li:before { content: ""; display: block; position: absolute; top: 0; left: -5px; width: 10px; height: 10px; text-align: center; background: #4BACFD; border-radius: 50%; } .last_progress{ border: none; } .last_progress::before{ content: "●"; display: table-cell; position: absolute; vertical-align: middle; left: -6px; width: 14px; height: 14px; line-height: 11.5px; text-align: center; background: rgba(75, 172, 253, .3); color: #4BACFD; font-size: 18px; border-radius: 50%; } .progress_content{ position: absolute; top: -4px; } .progress_title{ font-size: 15px; color: #222; font-weight: 600; margin-bottom: 3px; } .progress_time{ color: #999999; font-size: 12px; } .active{ color: #2BA0FF; }

JS部分:

var progressList = [ {'progress_title':'无感支付签约成功','progress_time':'2020.06.10 09:00'}, {'progress_title':'提额申请提交成功，银行审核中。','progress_time':'2020.06.10 10:00'}, {'progress_title':'提额审核通过，提额额度xxxx元。','progress_time':'2020.06.10 10:05'}, {'progress_title':'提额成功，当前可用额度为10000元','progress_time':'2020.06.10 10:05'} ] function renderProgress(progressList){ var progressBox = document.querySelector('.progress_box'); console.log(progressBox) console.log(progressList); var progressTemplate = '' for(var i = 0; i < progressList.length; i ++){ if(i == progressList.length - 1){ progressTemplate += "<li class='last_progress'><div class='progress_content'><p class='progress_title active'>"+progressList[i].progress_title+"</p><p class='progress_time'>"+progressList[i].progress_time+"</p> </div></li>" }else{ progressTemplate += "<li><div class='progress_content'><p class='progress_title'>"+progressList[i].progress_title+"</p><p class='progress_time'>"+progressList[i].progress_time+"</p> </div></li>" } } progressBox.innerHTML = progressTemplate }renderProgress(progressList)
