This article mainly introduces two examples of how to implement tab switching with javascript. It is a further extension of the principle of the previous method. Students who need an in-depth understanding can refer to

The previous article "Javascript implements tab switching" "Four Methods" talks about four different implementation principles of tab switching. Now it's time to connect theory with practice. Here are a few examples.

1. Imitate the tab switching of the official website of "Renmin University of China". The background is a picture. The rendering is as follows:

 var tabs=document.getElementById("tab").getElementsByTagName("li");
 var ps=document.getElementById("tabCon").getElementsByTagName("p");
 
 for(var i=0;i<tabs.length;i++){
 tabs[i].onmouseover=function(){change(this);}
 }
 
 function change(obj){
 for(var i=0;i<tabs.length;i++){
 if(tabs[i]==obj){
 tabs[i].className="fli";
 ps[i].className="fp";

This example is a very simple and common tab switch. What is more in js is to change the background image. Position, the rest is simple style.

2. Use input:checked to achieve the tab switching effect. Now use this principle and add css3 to make a beautiful example. When switching, the content area will gradually appear. The rendering is as follows:
