Two examples of tab switching using javascript_javascript skills-JS Tutorial-php.cn

The previous article "Four ways to implement tab switching in JavaScript" talked about 4 different implementation principles of tab switching. So, now it’s time to connect theory with practice. Here are a few Example.

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

The effect when the mouse is moved over the news

The effect when the mouse is moved over the announcement

The effect when the mouse is moved to communicate

The academic, communication and literary content is empty and I did not write anything. The complete code is as follows:

This example is a very simple and common tab switch. The extra thing in js is to change the position of the background image, and the rest is a 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:

The effect when the mouse clicks on HTML/CSS

The effect of AJAX when the mouse clicks

The complete code is as follows:

 <!DOCTYPE html>
 <html>
 <head>
 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
 <title>input:checked实现tab切换</title>
 <style>
 .tabs{
 color: #FFF;
 font-family: "微软雅黑";
 }
 input{
 opacity: 0;/*隐藏input的选择框*/
 }
 input:checked+label{
 padding-bottom: 6px;
 font-weight: bold;
 }
 label{
 cursor: pointer;/*鼠标移上去变成手状*/
 float: left;
 
 width: 120px;
 line-height: 40px;
 margin-right: 5px;
 text-align: center;
 }
 .tabs label:nth-of-type(1){
 background: #5eb0de;
 }
 .tabs label:nth-of-type(2){
 background: #86cad7;
 }
 .tabs label:nth-of-type(3){
 background: #e9bab3;
 }
 .tabs label:nth-of-type(4){
 background: #a8c194;
 }
 label:hover{
 font-weight: bold;
 }
 /*选择前面有.tabs input:nth-of-type(x):checked的.panels .panel:nth-child(x)*/
 .tabs input:nth-of-type(1):checked~.panels .panel:nth-child(1){
 opacity: 1;
 background: #5eb0de;
 -webkit-transition: .3s;
 }
 .tabs input:nth-of-type(2):checked~.panels .panel:nth-child(2){
 opacity: 1;
 background: #86cad7;
