Dynamically checking ID's in a dynamically built table problem ??

Question

Im creating a table dynamically using JSP and Javascript....
its a basic loop that goes through 5 iterations...as follows
what is happening here is it dynamically in the body creates my
table and when it hits the the row that has i = 1 or i = 3
it puts out a checkbox on the table....the code between the <%
and %> is the jsp portion..this runs on a server....I have two strings CheckBox1 and CheckBox3 which get assigned to two different table rows id's ...so for the first row the table gets created with no checkbox strictly text for the second row it has a checkbox and the forth row has one...
now what I want the code to do...is if the user hits a button on my page...
I want to call a javascript function that will go thru the rows and determine
if it has a checkbox and if so....if that checkbox is checked off. The called function obviously will not know the exact id at the time...since this is built dynamically sometimes I will have CheckBox0 containing a checkbox...Ct will all depend on the data...is there a way to check whether a row has an id
and if so what that id is..and also if it is a checkbox and finally if its checked off ????
<%! String checkString1 = null;
String stringInt = null;
String checkBoxText = "CheckBox";
int x = 0;%>
<% for(int i = 0;i < 5; i++)
{%>
<%stringInt = (new Integer(i)).toString();
checkString1 = checkBoxText + stringInt;
String[] stringnames = new String[2]; %>
<tr class="checkboxtext" id=chkb1>
<td width=100 valign="top" nowrap >
Corporates</td>
<td width=60 valign="top" >202
</td>
<td width=100 valign="top" >111021AC5R</td>
<td width=190 valign="top" nowrap class="displaytext">
BRIT TELECOM PLC </td>
<td width=85 valign="top" align=right>12/15/01
</td>
<td width=70 valign="top" align=right>8M</td>
<td width=70 valign="top" align=right >$105.5000</td>
<td width=100 valign="top" nowrap align=right>
12.5000</td>
<% if(i ==1 | i ==3)
{%>
<%stringnames[x] = checkString1;
System.out.println("your checkstring value is " + checkString1);
System.out.println("your mmmy value is " + stringnames[x]);
x = x + 1;
%>
<td width=200 valign="top" id=na1 onMouseOver="tryonmouseover(this)"; onMouseOut="nd();">Needs Approval
</td>
<td width=20 valign="top" ><Input type="checkbox" value="OFF" Name="check1" id=<%= checkString1 %> onclick="checkboxclickunclick(this)");" onMouseOver="tryonmouseover(this)"; onMouseOut="nd();">
<%}
else
{%>
<td width=200 valign="top" class="displaytext">Executed
</td>
<td width=20 valign="top" class="displaytext">N/A</td>
<%}%>
</td>
</tr>
<%}%>
</table>
further down is this code...
<td width="33%" align=center ><INPUT TYPE="BUTTON" VALUE="Approve all" id=apprall onclick="window.approveall()" class=actionbutton</td>
which will call approveall(). This is the function that I want to go
thru the table rows....and determine if there is a checkbox and whether it was checked off ???? Thanks for any help .....

I'm not sure myself how to do what you're asking for, but using DOM (Document Object Model) you can gain access to all objects of an HTML document. You should be able to give your table an id and then access all the rows of the table using JavaScript and DOM.
Or, you could probably just find an easier way to accomplish what you're asking for. Maybe just use the JavaScript onClick event to append your values to the query string, or whatever it is that you're trying to do.
