The trick is to have a hidden field with the same property as the
checkboxes... then you have an array of checkbox ids that you can iterate
through.
I had a form where I wanted to delete a bunch of rows from a table... the
user has to select which row to delete by checking a checkbox and then
when they click submit I iterate through the checkbox array and remove any
values I find there from the IDs array... this gives me an array (well, a
Collection in this case, an ArrayList to be precise) of unchecked
checkboxes.
Understand what I mean? Hope so. Something like:
// get the rows that have not been selected for deletion
// first get all of the ids on the form
Collection allRows = new ArrayList();
for(int i = 0; i < form.getRowIds.length; i++)
{
allRows.add(form.getRowIds()[i]);
}
// next remove the selected ids
for (int i = 0; i < form.getCheckedIds().length; i++)
{
allRows.remove(form.getCheckedIds()[i]);
}

I had the same problem....when we do
request.getParameterValues(ARRAY_OF_CHECKBOX) the unchecked checkboxes
didnt
appeared in the new array...only the checked ones were there.

Hi All,
I have many checkboxes with the same name in my html form. I use struts
framework. When i submit the form, will i be able to access the
checkboxes as an array in the form bean? Or should i have a seperate
field for each checkbox in the formbean?
Regards
Vasudevrao gupta
