The example in this article describes the effect of js controlling the left and right scrolling switching of multiple images. Share it with everyone for your reference. The details are as follows:
This is a pure js tool that realizes automatic left and right smooth scrolling of images by clicking the left and right buttons. The default is left and right scrolling in groups of 5. You can manually modify the js parameters to change the number of slides.
Operation rendering: -------------------View effect-------------------

Tips: If the browser does not work properly, you can try switching the browsing mode.
The js code shared with you to control the left and right scrolling switching effect of multiple images is as follows 

<head>

<script type="text/javascript">

 var oUl = oDiv.getElementsByTagName("ul")[0];
