The example in this article describes the js implementation of the Select list menu with an introduction. Share it with everyone for your reference. The details are as follows:

The Select list menu special effects code with introduction is not a navigation menu. It is a drop-down list menu commonly used in forms. The menu names and links defined in it can be modified by yourself. The difference is that a description function has been added. The mouse When you click on the content in the list, an introduction to this content will pop up, and the content in the text box will also change accordingly.

The screenshot of the running effect is as follows:

The online demo address is as follows:

<body>
<script language="JavaScript"> 
<!--
function herfto(){
  if (document.stationform.refsel.options[0].selected){ //根据用户选定的项目
    window.location.href = "http://www.jb51.net";} //改变本窗口的地址
  else if (document.stationform.refsel.options[1].selected)
  {  window.location.href = "http://www.sina.com.cn";}
  else if (document.stationform.refsel.options[2].selected)    
  {  window.location.href = "http://www.sohu.com";}

 //根据可选条目，这里应该相应的增减。
  return true; 
  }
function textValue(){ 
  var stationInteger, stationString  
  stationInteger=document.stationform.refsel.selectedIndex //取得选定项目的编号
  stationString=document.stationform.refsel.options[stationInteger].title //根据编号取得相应说明
  document.stationform.stationtext.value = stationString } //将说明显示出来
//-->
