Close active document without saving and without prompt

Hi together,

after some years I came back to PhotoShop DOM scripting. And obviously something ( a lot maybe ? ) has changed perhaps.

I used the old DOM Documentation from a PhotoShop version about 10 years back, that gave me the wrong Enumerator regarding the close() method:

https://www.indesignjs.de/extendscriptAPI/photoshop2015.5/#Document.html#d1e47935__d1e48452

https://www.indesignjs.de/extendscriptAPI/photoshop2015.5/#SaveOptionsType.html#d1e26997

Old DOM Documentation said: SaveOptionsType.DONOTSAVECHANGES.

I finally found the right one in a more recent PhotoShop script on the web with: SaveOptions.DONOTSAVECHANGES

To my surprise PhotoShop 2025 did do no error message when I used the wrong enumerator. It just did nothing.

PhotoShop 2023 at least gave me a clue with the error message ( translated from German )  : "Error 2 SaveOptionsType is undefined".

What worked in PhotoShop 2023 and 2025 was:

app.activeDocument.close( SaveOptions.DONOTSAVECHANGES ) ;

Two questions remain:

[1] Is there a current DOM documentation for ExtendScript out there for PhotoShop 2025?

[2] Why did PhotoShop 2025 issue no error message on the same script?

app.displayDialogs was set to DialogModes.ERROR I finally learned.

Why? I have no idea. Is this the new default perhaps?

Now that I changed app.displayDialogs to DialogModes.ALL, the error message is coming up with PhotoShop 2025 just like PhotoShop 2023 did.

Thanks,

The scripting reference has these constant values for PsSaveOptions as

1 (psSaveChanges)

2 (psDoNotSaveChanges)

3 (PsPromptToSaveChanges)

I code in Python and this worked for me:

docRef.close(2)

Not sure why, but this answer didn't work for me.

Instead, I used below:

app.activeDocument.close(SaveOptions.no);
