Hyperlink tag:

<a>

Two usages:

Hyperlink:

<a href="">
[code]<a href="htpp://www.sina.com.cn" target="_blank">新浪</a>
<!-- href属性值可以使url,也可以是本地文件。target属性是指定在哪个窗口或者帧中打开 -->

Location tag:

<a name="">

Generally used on pages. When the page content is too long, positioning markers are more convenient than drag strips.

Positioning tags are only effective when used in combination with hyperlinks.

[code]<a name="标记">标记位置</a>
<p>....<!-- 很多空行以制造网页过长的效果 -->
<a href="#标记">返回标记位置</a>
<!-- 使用标记时一定在href值的开始加入#标记名 -->
[code]<!DOCTYPE html> 
<html> 
<head>   
<meta charset="utf-8">   
<!-- Always force latest IE rendering engine (even in intranet) & Chrome Frame         
Remove this if you use the .htaccess -->   
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">   
<title>link</title> 
</head> 
<body>     
<!--         
超链接:         
作用:连接资源         
当有了href属性才有了点击效果。         
hred属性值的不同,解析方式也不一样。         
解析时,如果该值没有指定过任何协议,按照默认的协议来解析该值的。默认协议是file协议
