How to truly silently open a document?

[tobiask43046735]

I'm using a script (see also related question) to export all documents of a book to IDML:

var contents = app.activeBook.contents;  
for(var i=0, content; i < contents.length; i++) {  
    content = contents;  
    var filename = content.fullName.fsName;  
    var document = app.open(filename, showingWindow=false);  
    var idmlname = filename.substr(0, filename.lastIndexOf(".")) + ".idml";  
    document.exportFile(format=ExportFormat.INDESIGN_MARKUP, to=File(idmlname));  
    document.close(saving=SaveOptions.NO);  
}  

I'd like this process to be as unattended as possible, but unfortunately sometimes a cross-reference is outdated and I'm asked to update it there might also be other user-interaction interruptions I haven't yet encountered but would also like to cover).

Is there any way to open a document in a "yeah, just open it the way it is without asking the user"?

use the below line in first of your code..

app.scriptPreferences.userInteractionLevel = UserInteractionLevels.NEVER_INTERACT;

But before you exit, make sure to set it back!

try{

     app.scriptPreferences.userInteractionLevel = UserInteractionLevels.NEVER_INTERACT;

}

catch(_){}

finally{

     app.scriptPreferences.userInteractionLevel = UserInteractionLevels.INTERACT_WITH_ALL);

}
