Hi,
I am just playing around with JavaScript and some action for a button.
But now I think I have a serious problem.
It looks like that the method FormFieldJavaScriptAction has a restriction in the length of the JavaScript string; It complains if the Javascript string is longer than 255 character....
So If I would like to create more complex tasks by a button click It will not work?
It there a way solve this problem?

Regards
Niels

Hi Niels!

I've never tried the complete length. If it's so like you're explaining then perhaps it's possible to work with AddGlobalJavaScript and GetGlobalJavaScript building your script regarding the special situation?
Perhaps you can use code like this:
<script src="http://www.sample.com/example.js" type="text/javascript">
... to use external scripts?

Cheers, Ingo

Hi Ingo,
I can't use external JavaScript.
The PDF files we are creating are used offline! (The user edits the form data local and submits it later when he is online again back to us)
But the support told me that they will have a look in this matter.
Thanks
Cheers Niels

The 255 character limit is for string constants in Delphi, so it's nothing to do with Quick PDF Library. The easiest way around this to to break it up into multiple strings:

LongString := 'app.alert("This is a Long message window ' +

'which can be displayed because the string Literal is ' +

'bigger than 255 characters long <spacefiller><spacefiller>' +

'<spacefiller><spacefiller><spacefiller><spacefiller>' +

'<spacefiller><spacefiller><spacefiller>!");';
