This article mainly introduces the JS method of switching to display hidden content by clicking on a link, involving javascript mouse event response and dynamic transformation of page element attributes related operating techniques. Friends who need it can refer to it. I hope it can help everyone.

Let’s take a look at the running effect first:

<!DOCTYPE html> 
<html> 
<head> 
 <meta charset="UTF-8"> 
 <title>www.jb51.net 点击链接切换显示隐藏内容</title> 
 <style> 
  a { 
   cursor: pointer; 
   color: red; 
  } 
  #p1, #p2 { 
   display: none; 
  } 
 </style> 
</head> 
<body> 
 <a onclick="con(1)">显示内容1</a> 
 <a onclick="con(2)">显示内容2</a> 
 <p id="p1">11111</p> 
 <p id="p2">22222</p> 
 <script> 
  flag = "p1"; 
  function con(i){ //参数传递时传递字符串似乎有问题，这里采用的是数字传参 
   document.getElementById(flag).style.display = "none"; 
   document.getElementById("p" + i).style.display = "inline"; 
   flag = "p" + i; 
  } 
 </script>
