求一段代码，简单的选择操作！50分相送，描述清晰
<form>
<ul>
    <li> <input   name= "search "   type= "text "   class= "search "/> </li>
    <li> <input   name= "radio "   type= "radio "   value= " "   class= "radio "   /> 搜索引擎   <input   name= "radio "   type= "radio "   value= " "   class= "radio "/> 数据库 </li>
    <li> <input   name= " "   type= "submit "   class= "submit "   /> </li>
</ul>
</form>
------------------------------------
根据两个radio的不同选择，调用不同的函数，然后提交后执行
比如，选中“搜索引擎”，点击提交后，就将数据提交到baidu.com。     选择数据库后，就链接到test.asp，将参数传递过去

求一段详细代码，谢谢

用错了getElementById( 'radio1 ')[0]
你这样肯定报错
应该是 getElementsByName( 'radio1 ')[0]
------解决方案--------------------
2楼的倒是没错 反正实现的方法很多
另外不知道这么写是不是好点
<form onsubmit= "if(document.getElementsByName( 'radio1 ')[0].checked){this.acrion= 'http://www.baidu
