Checking the value by name will only work if your servlet knows what to
expect. However, if you are just looking for a way that you can add an
unchecked checkbox to the POST request on submission, do this:
function commit() {
if (validateForm()) {
document.addForm.action="/servlet/DoUpdate?jrunsessionid=927126305874342151"
if (!document.addForm.Person_Pets.checked){
document.addForm.action+="&Person_Pets=NULL";
}
if (!document.addForm.Person_Mail_Me.checked){
document.addForm.action+="&Person_Mail_Me=NULL";
}
...
document.addForm.submit();
return true;
}
else return false;
}
Then in your HTML, leave the action of your FORM tag blank (since that is
filled in by the Javascript) and for your submit button, have something like
this:
<INPUT type="submit" value="Save Changes" onClick="commit()">
Hope that helps...
