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>
