So I am writing a script for Photoshop using Javascript and I have a selection that I want to flip vertically and then invert the colors of a layer, however I can't seem to find a command on how to do this.

Here's what I've tried:

docRef.selection.select(shapeRef)

docRef.activeArtLayer.Invert()

docRef.activeArtLayer.flip(Direction.VERTICAL)

I haven't checked your other lines, but your invert line should be:

docRef.activeLayer.invert()

    This answers Chuck Uebele​ before

    var docRef = app.activeDocument;
    docRef.activeLayer.invert();

    This will flip the active layer (a code IMHO written by Paul Riggott)

    FlipLayer('Vrtc');
    function FlipLayer(direction) {
    // direction = "Vrtc" or "Hrzn"
    function cTID(s) { return app.charIDToTypeID(s) };
    function sTID(s) { return app.stringIDToTypeID(s) };
    var desc01 = new ActionDescriptor();
    var ref01 = new ActionReference(); ref01.putEnumerated(cTID('Lyr '), cTID('Ordn'), cTID('Trgt') );
        desc01.putReference(cTID('null'), ref01);
        desc01.putEnumerated(cTID('Axis'), cTID('Ornt'), cTID(direction));
    executeAction(cTID('Flip'), desc01, DialogModes.NO);
    }

    And this will set your (rectangle) selection (the values are hardcoded)

    var shapeRef = [[0, 0], [0, 150], [200, 150], [200, 0]];
    docRef.selection.select (shapeRef);

    Have fun
