div css 实现tabs标签的思路及示例代码

jerry CSS 2016年03月06日收藏

1、创建页签，以及页签内容的div。

2、编写被选中的页签和页签内容div显示、隐藏的样式。

3、编写js方法，根据被选中的页签，显示相应的页签内容。

例如：

 
<!doctype html> 
<html lang="zh-cn"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<script type="text/javascript"> 
function doClick(o){ 
//当前被中的对象设置css 
o.className="nav_current"; 
var j; 
var id; 
var e; 
//遍历所有的页签，没有被选中的设置其没有被选中的css 
for(var i=1;i<=7;i++){ //i<7 多少个栏目就填多大值 
id ="nav"+i; 
j = document.getElementById(id); 
e = document.getElementById("sub"+i); 
if(id != o.id){ 
j.className="nav_link"; 
e.style.display = "none"; 
}else{ 
e.style.display = "block"; 
} 
} 
} 
</script> 
<style type="text/css" media="screen"> 
body, div, dl, dt, dd, ul, ol, li, h1, h2, h3, h4, h5, h6, pre, code, form, fieldset, legend, input, button, textarea, p, blockquote, th, td { margin:0; padding:0 } 
fieldset, img { border:0 none } 
:focus { outline:0 } 
.dis{display:block;} 
.undis{display:none;} 
ol, ul { list-style:none } 
.fr { display:inline; float:right!important } 
.fl { display:inline; float:left!important } 
.show { display:block } 
.hide { display:none } 
.highlight { color:#F30!important } 
.important { font-weight:bold!important } 
.center { text-align:center!important } 
body { font:12px/1.5 tahoma, sans-serif; color:#333 } 
a { text-decoration:none; color:#333 } 
a:hover { text-decoration:underline; color:#E30751 } 
.nav_current{ float:left;background:#FFF; color:#F00; } 
.nav_link{ float:left;} 
.nav_current:hover ,.nav_link:hover{ color:#FF6600;} 
#dww-menu { width:978px; overflow:hidden; border:1px #dcdcdc solid; } 
#dww-menu .mod-hd { overflow:hidden; height:30px; line-height:30px; position:relative; background:#CCCCCC repeat-x 0 0 } 
#dww-menu .mod-hd li { float:left; cursor:pointer; text-align:center; height:30px; line-height:30px; padding:0 10px; letter-spacing:1px; text-transform:uppercase; border-right:1px #dcdcdc solid } 
#dww-menu .mod-hd li.hover { font-weight:900; background:#FFF } 
#dww-menu .mod-bd { padding:5px 10px } 
#dww-menu .mod-bd div {color:#BFBFBF; line-height:24px } 
#dww-menu .mod-bd div.show { display:block } 
#dww-menu .mod-bd div a { display:inline-block; padding:0 4px } 
</style> 
<base target="_blank" />
