File close using script prompt message

Thanks Beginner_X for reply

I try :

var myDocument=app.activeDocument;

myDocument.close(1852776480);

SaveOptions.no value is 1852776480.

I think that there is no difference in

app.activeDocument.close(SaveOptions.no)

and

var myDocument=app.activeDocument;

myDocument.close(1852776480);

In prompted message :

Save changes to the Adobe InDesign document "Abc.indd" before closing ?

Don't Save                                                                     Cancel          Save

I want to say Don't Save using script.

I want to close my modified active document without save using script.

How close this ?

Thanks
