Hi,

2. I need function which return array with names or identificators of effects fot each layer.

I have function which return T/F if layer has effect. But I don't know how

Thank you Domaneni

This function will return an array of effect names for the active layer. You can get the effects count from the array's length property. The effect names are Action Manager names so if you want them to match the GUI you will need to translate. i.e. stroke in action manager is frameFX

function getEffects() {
    var ref = new ActionReference();
    ref.putEnumerated( charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );
    var desc =   executeActionGet(ref);
    if ( desc.hasKey( stringIDToTypeID( 'layerEffects' ) ) ) {
        var effects = [];
        var effectDesc = desc.getObjectValue(  stringIDToTypeID( 'layerEffects' ) );
        // first key is scale so skip and start with 1
        for ( var effect = 1; effect < effectDesc.count; effect++ ) {
            effects.push( typeIDToStringID( effectDesc.getKey( effect ) ) );
        }
        return effects;
    }
}
