Re-Usage of Javascript-Snippets / subroutines?

[Peter2]

Under "Document-Properties" there is a feature where I can manage named JS snippets:

I wonder if these "snippets" could be re-used under "Javascript actions" of form-fields?

Simple Example:
I have fields with values a, b and c.

- I want to create a button which read these fields and check if they are valid.
- Then I need a button which calculates something with these values: a plus b minus c ..
- Finally I need a button which takes the values, creates a filename and save the file

So the beginning of these codes are always the same - read and store the data of a, b and c.

In other code I would create and call "subroutines". is it possible here?

Have a fine weekend and thanks for your great support!

Yes, and that's the main purpose of document-level 'snippets'.
The code of these snippets is executed on the document open.
You can define a function in this document-level code, and use this function in field action handlers.

Thanks, Ivan

...You can define a function in this document-level code, and use this function in field action handlers....

Is there an example for this?

BTW:
Are there some downloads for the user which demonstrate different / special / sophisticated features of the software and the PDF-format?

Hello Peter2,

The "function" referred to above is this:
https://developer.mozilla.org/en-US/doc ... /Functions

You declare it with a name and input parameters, and then there is code inside of it that takes the input, processes it in some way and returns to you some output. You can then call this function from various places in your document.

We do not have JS specific tutorials, but this might also be of good use:

Thanks Stefan, OK for me.
