用AUI做个例子，在下拉列表中点击一个外部链接(如Google首页“更多”菜单的下拉中的项目)时，弹出alert对话框，信息如下，而代码中没搜到哪里有这些文字。

It's cold outside, there's no kind of atmosphere,
I'm all alone, more or less,
Let me fly, far away from here,
Fun, fun, fun, in the sun, sun, sun...
I want to lie shipwrecked and comatose,
Drinking fresh mango juice,
Goldfish shoals, nibbling at my toes,
Fun, fun, fun, in the sun, sun, sun...
Fun, fun, fun, in the sun, sun, sun...

不知是怎么回事，谁知道？
