Popup Confirmation Before Add

BeforeAdd happens on the web server meaning you cannot use Javascript interaction there. Luckily there is much easier way to achieve this:

Hello
Yes i've tried this but nothing happened.
My code in the javascript onload from the add page :
if (proxy.uitgaven > proxy.Totaal)

{

this.on('beforeSave', function(formObj, fieldControlsArr, pageObj)

{

if (confirm('U bent over budget, bent u zeker dat u deze boeking wilt doen'))

return true;

else

return false;

});

}
And i assigned the values in the before.display page
$pageObject->setProxyValue("totaal", $_SESSION["Totaal"]);

$pageObject->setProxyValue("uitgaven", $_SESSION["Uitgaven"]);
Can you see anything wrong.
Nothing happens at all ?

Variables in Javascript are case-sensitive. Totaal and totaal are two different variables.
In general, you need to make sure your code works. Make sure no Javascript errors happening there. This article can help you troubleshoot Javascript code:

Another advice - before adding new code make sure that the sample code from the manual works. Once you got it working you can start adding your own logic.

Ok i corrected it. But the problem that keeps existing is that the "ask for confirmation" not worked.
I could only add records inline, so changed that for testing and now it works.
But i need to ask for the confirmation with the inline add. Is this possible ?

Without seeing the whole application it is very little we can do.
