The example in this article describes the simple demonstration code of jQuery to achieve the tab switching effect. Share it with everyone for your reference. The details are as follows:

The operation effect diagram is as follows

1. Main program

<!DOCTYPE html>
<html>
 <head>
 <meta charset="utf-8" />
 <title>选项卡</title>
 <link type="text/css" rel="stylesheet" href="css/layout.css" />
 </head>
 <body>
 <!--整体构局说明，用ul完成按钮的横向布局，用div完成三个内容框架的垂直布局（类似于类表），然后将三个内容框架全隐藏，通过下面的:first-child属性只将第一个框架内容显示出来-->
 <div class="tab">
 <div class="tab_menu">
 <ul>
 <li class="on">实事</li>
 <li>政治</li>
 <li>体育</li>
 </ul>
 </div>
 <div class="tab_box">
 <div>实事内容</div>
 <div>政治内容</div>
 <div>体育内容</div>
 </div>
 </div>
 <script type="text/javascript" src="js/jquery-1.11.3.js"></script>
 <script type="text/javascript" src="js/layout.js"></script>
 </body>
</html>

2. CSS style
Preliminary layout code:

*{ margin:0; padding:0}
ul{
 list-style: none;
}
.tab{
 width: 300px;
 margin: 0 auto;
}
.tab .tab_menu{
 border: 1px solid #000000;
 height: 30px;
 width: 300px; 
}
.tab .tab_menu ul li{
 float: left;
 width: 99px;
 text-align: center;
 line-height: 30px;
 border-right: 1px #333333 solid;
}
.tab .tab_menu ul li:last-child{
 border-right:none;
 width: 100px;
}
.tab .tab_menu ul li.on{
 background: #999;
}
.tab .tab_box > div{
 width: 300px;
 height: 200px;
 border: #333333 solid;
 border-width: 0 1px 1px 1px;
}

The above code implements the layout as follows:

But we only need the content in a frame to be displayed, so just add some small code to assist with the above code~~~~~~

Further layout style code:

*{ margin:0; padding:0}
ul{
 list-style: none;
}
.tab{
 width: 300px;
 margin: 0 auto;
}
.tab .tab_menu{
 border: 1px solid #000000;
 height: 30px;
 width: 300px; 
}
.tab .tab_menu ul li{
 float: left;
 width: 99px;
 text-align: center;
 line-height: 30px;
 border-right: 1px #333333 solid;
}
.tab .tab_menu ul li:last-child{
 border-right:none;
 width: 100px;
}
.tab .tab_menu ul li.on{
 background: #999;
}
.tab .tab_box > div{
 width: 300px;
 height: 200px;
 border: #333333 solid;
 border-width: 0 1px 1px 1px;
 display: none; //将三个内容框架全隐藏，通过下面的:first-child属性只将第一个框架内容显示出来
}
.tab .tab_box > div:first-child{
 display: block;
}

Copy after login

The above program adds an additional display: none to the .tab .tab_box > div style. In addition, only the first frame content is displayed through the :first-child attribute~~~~~~This is what we see The layout is consistent with the animation renderings I just posted above, and the layout is considered complete~~~~~~
3. Jquery code:

$(function(){
 $(".tab_menu ul li").click(function(){
 $(this).addClass("on").siblings().removeClass("on"); //切换选中的按钮高亮状态
 var index=$(this).index(); //获取被按下按钮的索引值，需要注意index是从0开始的
 $(".tab_box > div").eq(index).show().siblings().hide(); //在按钮选中时在下面显示相应的内容，同时隐藏不需要的框架内容
 });
});
