单选按钮的问题！怎么才能实现 没点中为灰色 选中的可以写东西拿？？？？？？
下面这段代码中，我点中radio1时只操作文本rq1内容，其他为灰色不允许操作，点中radio2时只操作文本rq2内容，其他为灰色不允许操作。。。。。。。。
代码如下：
<table>
<tr>
<td> <input name= "radio1 " type= "radio " value= "1 "> </td> <td> <input name= "rq1 " type= "text "> </td>
</tr>
<tr>
<td> <input name= "radio2 " type= "radio " value= "2 "> </td> <td> <input name= "rq2 " type= "text "> </td>
</tr>
<tr>
<td> <input name= "radio3 " type= "radio " value= "3 "> </td> <td> <input name= "rq3 " type= "text "> </td>
</tr>
<tr>
<td> <input name= "radio4 " type= "radio " value= "4 "> </td> <td> <input name= "rq4 " type= "text "> </td>
</tr>
</table>
