Check boxes

[GangWU]

Is there anyone who is using webmacro?

I have a group of checkboxes in one html page. After check some of them it goes to next page while it calls java servlet function. I can use getParameter("checkbox name") to retrieve the boxes but I don't know how I can tell which box was checked.

Any help is appreciated.

If getParameter("checbox name") returns an empty string ("") or NULL, the checkbox was not checked.
If it returns whatever you specified in the 'value'-attribute of the checkbox, the checkbox was checked.
