detecting change to a form field

[joeitaliano]

hello

i have a PDF file opened that has several tick boxes

what i want to do is to insert/remove a page(s) depending on the state of that tick box

is there any way to detect a change to a form field returning information about what has changed

many thanks

Hello Joe,

You will need to have a script that listens for events for the particular field (that check box), and when an event is fired - use the isBoxChecked method, but I am not quite sure whether this is currently supported in our SDK - so I have asked for some help from the dev team.

Cheers,
Stefan

Hi, joe.

In the new build(upcoming) you will be able to intercept the new event:

Code: Select all

eventhandler OnEvent(type, name,....)
{
    if ((type == PXCVA_OnNamedNotify) AND (name == "Notifications.FieldChanged"))
    {
        string fn; 
        ctrl.GetProperty("Notifications.FieldChanged.Name", fn, 0);
        string js = "var f = this.getField(" + fn + "); if (f != null) { f.value; };";
        string newVal; 
        ctrl.RunJavaScript(js, out newVal, ...);
        ....
    }
}

Wait for the new build and look to the updated SDK help, [Reference/NamedItems/Objects/Notifications/FieldChanged].

Best
Regards.
