passing checkbox array

I have following code in my jsp
...this code inside <logic:iterate tag> so it generates many checkboxes
<input type="checkbox" name="addAddresses[]" id="addAddresses[]" class="checkboxgroup1" value="<bean:write name="results" property="locationAddress" />"/>
....<logic:iterate> ends here

now i want to pass this checkbox group (the selected values) to thye servlet using my javascript function which looks like this

opener.location.href = "addressFind.do?requestAction=addAddresses&oid=" + oid

i tried passing it as a parameter but i m not able to .
how can i pass the selected checkboxes.
Thanks

If you are not submitting a form, you need to loop through the elements and build a string containing the information.

what is the exact syntax of doing that because I am trying to do something like this

document.getElementById ( "addAddresses" )[i].checked (where i is a loop variable

and of course it dont work.
thanks for your help

Why are you making it hard on yourself and using opener.location.href instead of submitting a form?

I also tried the following which apparently should work but its not working

var check = document.getElementById ("addAddresses") ;
alert (check.length);
for ( i = 0 ; i < check.length ; i ++ ){
alert ( check.checked ) ;
}

it says check.length is undefined and when i use check.size it gives the value of 0 although there are ten checkboxes. also when i try check.checked it gives me true or false depending on the first checkbox if its checked or not.

Thanks

IDs are singular so you can only have one element with the id. LIke an id number. Names are plural.

Thanks Bear and Eric

I would probably submit the form. The reason I was not submitting the form was because I need to close popup when this function is performed and also refresh the opener. Anyways I think I can submit the form and still be able to refresh my parent window. Thanks for your help.

By the way I found what I was doing wrong when i tried to access my checkboxes. I was supposed to call document.getElementsByName("addAddresses")
rather than ...ById.

Why are you not doing a form submission? You are recreating a normal form. LOL
