选择问题
我想实现一个功能，就是选择不同的选项，跳出不同的功能
请看代码
<tr>
<td>
<input type= "radio " value= "V1 " name= "R1 "> 从我的电脑上传 <br>
或者
<input type= "radio " value= "V1 " name= "R2 "> 输入图片URL
</td>
</tr>
<tr>
<td>
请输入图片的URL： <input type= "text " name= "T2 " size= "20 ">
</td>
</tr>
<tr>
<td>
请上传你的图片： <input type= "file " name= "T1 " size= "20 " >
</td>
</tr>
当我选择上面的R1，则下面只显示出T1，而选择R2的时候，只显示出T2，请问这个该怎么实现？
谢谢

{
if(document.getElementById( "R1 ").value!= " "){
document.getElementById( "R2 ").style.display= "none ";

if(document.getElementById( "R2 ").value!= " "){
document.getElementById( "R1 ").style.display= "none ";
document.getElementById( "T1 ").style.display= "none ";

<div id= "T1 "> 请上传你的图片： <input type= "file " name= "T1 " size= "20 " > </div>
