在页面上,Radio 改变时,如何在 text里显示Radio对应的选中值?
在页面上,Radio 改变时,如何在 text里显示Radio对应的选中值?
Radio和text都是非服务器控件,
代码如下:
<table width= "100% " border= "0 " cellspacing= "1 " cellpadding= "1 ">
<tr>
<td> <INPUT id= "Answer1 "type= "radio " value= "A "
name= "Answer1 "> A. </td>
</tr>
<tr>
<td> <INPUT id= "Answer1 " type= "radio " value= "B "
name= "Answer1 "> B. </td>
</tr>
<tr>
<td> <INPUT id= "Answer1 " type= "radio " value= "C "
name= "Answer1 ">
C. </td>
</tr>
<tr>
<td> <INPUT id= "Answer1 " type= "radio " value= "D "
name= "Answer1 "> D. <input type= "text " name= "FText "> </td>
</tr>
</table>
[解决办法]
循环判断Answer1的每个项的选中情况，然后处理。

<script>
function change()
{
for(i=0;i <document.all.Answer1.length;i++)

if(document.all.Answer1[i].checked){document.all.FText.value=document.all.Answer1[i].value}
}
}
