[OFF TOPIC] JavaScript + tag question

Posted by Adam Hardy <ah...@cyberspaceroad.com>.
I'd write some sort of function and call it from the event.

onchange="submitFromDropdown(this)"

and your function should be something like this:

submitFromDropdown(dropdown)
{
     //'this' == dropdown field object
     var fieldName = dropdown.name;
     var len = dropdown.options.length;
     var item = '';
     for (i = 0; i < len; i++) {
         if (dropdown.options[i].selected)
             item = dropdown.options[i].value;
     }
     var url = "/search.do?action=" + fieldName
         + "&selectedItem=" + item;
     dropdown.form.action = url;
     dropdown.form.submit();
}

I changed the code from my working code - usual disclaimers apply. You 
might need to debug it a little, but that's easy too.

I believe that document.forms[0].elements[anySelectbox].value will be 
invalid. .value only works on non-select form-elements. AFAIK without 
testing it now.
