Perhaps I am misunderstanding what your flowscript, form and binding looks
like. Based on what I understand I think you should be able to use the
on-action element as in the previous email to get the submitted value and
increment it accordingly in the form definition file or I suppose you could
use a javascript element binding to increment the value based on some other
widget's value in the binding file. The last suggestion is to do it inside
your flowscript method before the form.save(...). All of the suggestions
should do the incrementation before the actual binding. Someone else might
have better ideas... sorry.
function form2xml(form) {
// bind the document data to the form
form.load(document);
// shows the form to the user until is validated successfully
form.showForm(displayURI);
if (form.submitId == "cancel") {
// cancel out
cocoon.sendPage(cancelURI);
}
else {
// get and modify the submitted widget value
var mywidget = form.getWidget("contact.0.votes");
mywidget.value = mywidget.value + 1;
// bind the form's data back to the document
form.save(document);
}
}
<wb:javascript id="foo" path="foo">
<wb:load-form>
var appValue = jxpathPointer.getValue();
widget.setValue(appValue);
</wb:load-form>
<wb:save-form>
var formValue = widget.getValue();
var someOtherWidget = wigdet.parent.getWidget("contacts.0.vote");
if (someOtherWidget.value == 'true' // or whatever criteria) {
// vote
formValue = formValue + 1;
}
jxpathPointer.setValue(formValue);
</wb:save-form>
</wb:javascript>
