Dynamic Radios

[Tarun Sainanee <ta...@delhi.tcs.co.in>]

Hi all,

I am displaying search results on a jsp. I am also allowing the user to 
select a row by selecting a radio button. The value that will be returned 
to the calling screen will correspond to the radio selected. Thats exactly 
where my problem is. If only in a javascript function i can alert the 
value of the radio selected, i am done.
The following is the code that i am using in my jsp:'

                <logic:iterate id="myCollectionElement" name="options1" 
indexId="csLabel1" scope="request"> 
                  <tr>
                    <td>
                      <html:radio property="radioid" value="indexId" 
onclick="radioValue()"/>
                    </td>
                    <td>
                      <bean:write name="myCollectionElement" 
property="csLabel1"/>
                    </td>
                  <td>
                    <bean:write name="myCollectionElement" 
property="csLabel2"/>
                  </td>
                  <td>
                    <bean:write name="myCollectionElement" 
property="csLabel3"/>
                  </td>
                </tr>
                </logic:iterate> 


Can someone please tell me:
1. By what name will i access the radio in my javascript (I assume its 
radioid)?
2. Whats wrong in the code that i am using?

Any help or pointers to a working code????
