【DOM编程艺术】javascript:伪协议和onclick 弹出窗口(一)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>window.open</title>
</head>

<body>
<a href="#" onclick="popup('http://www.example.com/');return false;">Example</a>   //<a href="javascript:popup('http://www.example.com/')">Example</a>
<script>
function popup(winURL){
   window.open(winURL,'popup',"width=320,height=460");
}
</script>
</body>
</html>

onclik与用"javascript:"伪协议调用javascript代码的做法同样糟糕,因为它们都不能平稳退化

 

预留退路

<a href="http://www.example.com/" onclick="popup('http://www.example.com/');return false;">Example</a>

简化:

<a href="http://www.example.com/" onclick="popup(this.getAttribute('href'));return false;">Example</a>

 更简化:

 

<a href="http://www.example.com/" onclick="popup(this.href);return false;">Example</a>
