Why does this code don't work?
Could anyone help me on the right way?

I want to create a new backup of the current document each time the user saves it.

app.activeDocument.addEventListener("beforeSave" , myBKP);

function myBKP() {
    var doc = app.activeDocument;
    var myDate = myDate();
    var myDocName = doc.name.replace(".indd" , "");
    var myPath = Folder.decode(doc.filePath);
    if (!Folder(myPath + "/bkps").exists) {
        Folder(myPath + "/bkps").create();
        myPath = Folder(myPath + "/bkps");
        } else {
            myPath = Folder(myPath + "/bkps");
            }
    var myBkpFileName = new File(myPath + "/" + myDocName + ".idml");
    alert(myBkpFileName);
//~     doc.saveACopy(File(myBkpFileName));
    }





//GET DATES

function myDate() {
    var date = new Date();
    var day = (date.getDate() > 10 ) ? date.getDate() : ("0" + date.getDate() );
    var month = ((date.getMonth()+1) >= 10 ) ? (date.getMonth()+1) : ("0" + (date.getMonth()+1) );
    var year = (date.getFullYear() > 10 ) ? date.getFullYear() : ("0" + date.getFullYear() );
    var hours = (date.getHours() > 10 ) ? date.getHours() : ("0" + date.getHours() );
    var minutes = (date.getMinutes() > 10 ) ? date.getMinutes() : ("0" + date.getMinutes() );
    var seconds = (date.getSeconds() > 10 ) ? date.getSeconds() : ("0" + date.getSeconds() );
    var weekday = date.getDay();
    var myDate = String(year)+String(month)+String(day)+"_"+String(hours)+String(minutes)+String(seconds);
    return myDate;
    }

#targetengine "session"  
app.addEventListener("beforeSave", myBKP);

function myBKP() {
    var doc = app.documents[0];
    var myDate = myDate();
    var myDocName = doc.name.replace(".indd" , "");
    var myPath = Folder.decode(doc.filePath);
    if (!Folder(myPath + "/bkps").exists) {

            }
    var myBkpFileName = new File(myPath + "/" + myDocName + ".idml");
    $.writeln(myBkpFileName);
    doc.exportFile(ExportFormat.INDESIGN_MARKUP, File(myBkpFileName));

Also look into this by Marc Autret:

Can We Kill an Event?

http://www.indiscripts.com/post/2018/06/indesign-scripting-forum-roundup-12#hd1sb1

And also all the other entries there.

Then study properties and methods of object eventListener:

https://www.indesignjs.de/extendscriptAPI/indesign-latest/#EventListeners.html

https://www.indesignjs.de/extendscriptAPI/indesign-latest/#EventListener.html

There is a name property. And there is method itemByName() for example.

lf_corullon said:

Also, I tried a

app.activeDocument.removeEventListener("beforeSave" , myBKP);

to remove the eventListener (which, as you can see, I'm not familiar with).

Doesn't work.

If you used Kasyan's code this does not work, because he added the listener to app and not to the active document.

Yes, I know it. But I just changed the line where I used saveACopy to the exportFile.

And I tried to remove using my custom targetengine, and without it.

Then I tried an alert(app.activeDocument.eventListeners[0].eventType) to realize that this is really the one I added. I just can remove it using app.activeDocument.eventListeners[0].remove().

Thanks!

The error is because I'm trying a save process during a save process?

Because of this the export works (because it's not a save)?

I don't think so: unlike doing it manually in InDesign, you can't 'save it as IDML' by script using the saveACopy() method. You can only 'export it' with exportFile().
By the way, here are a couple of similar scripts:

Save with backup

Save versions
