Test for Layer Effects applied to a layer

[timmysmuckers]

I have a pretty complicated script I've been working on but coming up against an issue.

There is a portion of it I want to run only if a selected layer has Layer Effects applied to it. I have been searching all over this forum and haven't found the answer other than someone stating that it's possible. How does one detect Layer Effects?

Any help would be greatly appreciated.

I know there is a command to Copy Layer Effects "CpFX" that will fail the JS if the layer has no Effects applied to it. Is there some way to just test if the command is available?

function sTT(v) {return stringIDToTypeID(v)}
(ref = new ActionReference()).putEnumerated(sTT('layer'), sTT('ordinal'),
sTT('targetEnum')), executeActionGet(ref).hasKey(sTT('layerEffects'))

The presence of the layerEffects key is possible even when the layer does not have standard blending options, but there are no effects. The following function can help. It checks the availability of the scaleEffectsEvent command.

function has_visible_effects()
    {
    try { 
        executeAction( stringIDToTypeID( "scaleEffectsEvent" ), undefined, DialogModes.NO );
        return true;
        }
    catch (e) { return false; }
    }
