求点击改变内容的代码（要求能通过IE8安全保护）
如下代码默认为百度搜索：
<table> <tr> <td><table width="100%"> <tr align="center" id="controller"> <td style="background-color:#0FF">网页</td> <td>知道</td> <td>谷歌图片</td> <td>淘宝</td> </tr></table></td> </tr> <tr> <td id="searcher"><form action="http://www.baidu.com/s" target="_blank"> <input name="word" type="text" value="" /> <input type="submit" value="百度一下" /> </form></td> </tr></table>
<table> <tr> <td><table width="100%"> <tr align="center" id="controller"> <td>网页</td> <td>知道</td> <td style="background-color:#0FF">谷歌图片</td> <td>淘宝</td> </tr></table></td> </tr> <tr> <td id="searcher"><form action="http://www.google.com.hk/search" target="_blank"><input name="q" type="text" value="" /><input type="hidden" name="tbm" value="isch"><input type="submit" value="搜索图片" /></form></td> </tr></table>
