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;
/* margin-left: -6px; */
top: 0;
left: -5px;
width: 10px;
height: 10px;
/* line-height: 22px; */
text-align: center;
background: #4BACFD;
/* color: #fff; */
/* font-size: 14px; */
border-radius: 50%;
}
.last_progress{
border: none;
}
.last_progress::before{
content: "●";
display: table-cell;
position: absolute;
vertical-align: middle;
/* margin-left: -6px; */
/* top: 0; */
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)
