从建站以来一直挺喜欢google提供的这个网页翻译的小工具（http://translate.google.com/translate_tools?hl=zh-CN）。虽然他的实用性并不是很好，如基本没外国人看网站和翻译的都是“中式外语”等。呵呵。
废话不多说，看效果
随手说一下过程，分析，它原来是用js调用iframe的。但iframe不能域修改，就放弃了改成iframe，重新下了他的iframe内容改js。
结果：去掉ifame调用，写html代码。最后的效果嘛，看我blog首页。呵呵
下面是html代码，写于body里！
<form id="lang_form">
<select id="lang_select" onChange="dotranslate(this);">
<option value="" id="select_language">Select Language</option>
</select>
</form>

其实直接用地址跳转做下拉菜单就好了
