概述

这是我在学习课程Tab选项卡切换效果时做的总结和练手。

原课程中只有原生js实现,jquerybootstrap实现是我自己补上的。

本节内容

  • 标签页(tab)切换的bootstrap实现

js实现

标签页(tab)切换的原生js,jquery和bootstrap实现

说明:

  1. 代码是我自己写的,与课程中的不一样。
  2. 主要利用display:none来把部分内容隐藏而显示其它内容。
  3. 遇到了事件的循环绑定,我是利用添加id使其成为钩子来解决的。

代码:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>tab切换</title>
<style type="text/css">
*{
font-family: Times;
} #main {

border: 1px solid #c0c0c0;
} #top_column {
height: 30px;
width: 300px;
} #top_column div {

width: 75px;
background-color: #fffff0;
text-align: center;

top_column[i].id=i;
top_column[i].onmouseover=function(){
tab_content(this.id);

top_column[j].className="top_column_not_hover";

} top_column[i].className="top_column_hover";
bottom_column[i].style.display="block";
}
}
</script>
</body>
</html>

jquery实现

标签页(tab)切换的原生js,jquery和bootstrap实现

说明:

  1. 效果其实和原生js实现是一样的。

  2. 因为我想写一下jquery代码练练手,所以只是把原生js实现中的js代码改成了jquery的形式。

代码:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>tab切换</title>
<style type="text/css">
*{
font-family: Times;
} #main {
font-size: 13px;
height: 100px;
width: 300px;
border: 1px solid #c0c0c0;
} #top_column {
height: 30px;
width: 300px;
} #top_column div {
height: 30px;
width: 75px;
background-color: #fffff0;
text-align: center;
line-height: 30px;
border: 1px solid #c0c0c0;
margin: -1px -1px 0px -1px;
} #top_column div:hover {
background-color: #fff;
font-weight:bold;
color: orange;
} .top_column_hover {
background-color: #fff;
font-weight:bold;
color: orange;
} #bottom_column {
height: 70px;
width: 300px;
} #bottom_column a {
height: 35px;
width: 140px;
display: block;
text-align: left;
text-decoration: none;
outline: none;
color: black;
line-height: 35px;
padding-left: 10px;
float: left;
} #bottom_column a:hover {
color: orange;
} #main div {
float: left;
} </style>
</head>
<body>
<div id="main">

</div>
</div>
</div> <script src="http://how2j.cn/study/js/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript"> $(window).load(function(){
var $top_column=$("#top_column div");
var $bottom_column=$("#bottom_column div"); $.each($top_column,function(i,item){
$(item).hover(tab_content);
}) function tab_content(){
$.each($top_column,function(i,item){
$(item).attr("class", "top_column_not_hover");
}) $.each($bottom_column,function(i,item){
$(item).hide();
}) var index=$top_column.index($(this));
$bottom_column.eq(index).show();
$top_column.eq(index).attr("class", "top_column_hover");
}
})
</script>
</body>
</html>

bootstrap实现

标签页(tab)切换的原生js,jquery和bootstrap实现

说明:

  1. 代码中不需要额外写js,只需引用jquerybootstrap文件即可。
  2. 虽然不需要写js,但是缺点是需要点击,并且鼠标离开后回复原状,解决这些问题的话需要写js
  3. 虽然bootstrap看起来很华丽,而且很简便。但是在一些小改动上面很麻烦,而且会踩很多坑。所以如果需要细致并且频繁修改网站的话,不建议用bootstrap搭建网站。
  4. 踩坑记录:box-sizing 属性的content-boxborder-box(其实这也是盒模型的基本)。

代码:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>tab切换</title>
<style type="text/css">
*{
font-family: Times;
} #main {
font-size: 13px;
height: 100px;
width: 300px;
border: 1px solid #c0c0c0;
margin:10px 10px;
box-sizing: content-box;
} #myTab {
height: 30px;
width: 300px;
} #myTab div {
height: 30px;
width: 75px;
background-color: #fffff0;
text-align: center;
line-height: 30px;
border: 1px solid #c0c0c0;
margin: -1px -1px 0px -1px;
box-sizing: content-box;
} #myTab div:hover {
background-color: #fff;
font-weight:bold;
color: orange;
cursor: pointer;
