jquery implements digital scrolling effects

This time I will bring you jquery to implement digital scrolling special effects. What are the precautions for jquery to implement digital scrolling special effects? The following is a practical case, let's take a look.

There are separators and decimal points:

• Only delimiter:

  
  
  

• ##Only decimal point:
  
  
  
##No delimiter, No decimal point:

• Running rendering:

The specific code is as follows

<title>数字滚动插件</title>
<meta>
<script></script>
<style>
/*数字滚动插件的CSS可调整样式*/
.mt-number-animate{ font-family: &#39;微软雅黑&#39;; line-height:40px; height: 40px;/*设置数字显示高度*/; font-size: 36px;/*设置数字大小*/ overflow: hidden; display: inline-block; position: relative; }
.mt-number-animate .mt-number-animate-dot{ width: 15px;/*设置分割符宽度*/ line-height: 40px; float: left; text-align: center;}
.mt-number-animate .mt-number-animate-dom{ width: 20px;/*设置单个数字宽度*/ text-align: center; float: left; position: relative; top: 0;}
.mt-number-animate .mt-number-animate-dom .mt-number-animate-span{ width: 100%; float: left;}
</style>


<br><br>
有分隔符，有小数点：<p></p> <br><br>
只有分隔符：<p></p> <br><br>
只有小数点：<p></p> <br><br>
无分隔符，无小数点：<p></p>
