Enable or disable the selected layer mask - photoshop

Question

Can anyone help how I can disable or enable the layer mask of the selected layer?
I wanted to automate it via scrip not with action.
I can't provide any code yet since I don't know yet what to do.

Answer 1

Scriptlistener is your friend here.
// Switch off any dialog boxes
displayDialogs = DialogModes.ERROR; // OFF
layermask(true);
alert("Layer mask enabled");
// or
layermask(false);
alert("Layer mask disabled");
// Switch back on any dialog boxes
displayDialogs = DialogModes.ALL; // ON
function layermask(bool)
{
// =======================================================
var idsetd = charIDToTypeID( "setd" );
var desc22 = new ActionDescriptor();
var idnull = charIDToTypeID( "null" );
var ref5 = new ActionReference();
var idLyr = charIDToTypeID( "Lyr " );
var idOrdn = charIDToTypeID( "Ordn" );
var idTrgt = charIDToTypeID( "Trgt" );
ref5.putEnumerated( idLyr, idOrdn, idTrgt );
desc22.putReference( idnull, ref5 );
var idT = charIDToTypeID( "T " );
var desc23 = new ActionDescriptor();
var idUsrM = charIDToTypeID( "UsrM" );
desc23.putBoolean( idUsrM, bool ); // value set here
var idLyr = charIDToTypeID( "Lyr " );
desc22.putObject( idT, idLyr, desc23 );
executeAction( idsetd, desc22, DialogModes.NO );
}
Using a bit of Action manager code to get the state of the layer mask we can use:
// Switch off any dialog boxes
displayDialogs = DialogModes.ERROR; // OFF
var layerMaskState = false;
s2t = stringIDToTypeID;
var r = new ActionReference();
r.putProperty(s2t('property'), s2t('userMaskEnabled'));
r.putEnumerated(s2t('layer'), s2t('ordinal'), s2t('targetEnum'));
// Make sure that the object that executeActionGet
// returns contains this key (which means the layer has a mask):
var d = executeActionGet(r);
if (d.hasKey(s2t('userMaskEnabled')))
{
layerMaskState = d.getBoolean(s2t('userMaskEnabled'));
}
// Toggle it!
layerMaskState = !layerMaskState;
layer_mask(layerMaskState);
// Switch off any dialog boxes
displayDialogs = DialogModes.ALL; // OFF
function layer_mask(bool)
{
// =======================================================
var idsetd = charIDToTypeID( "setd" );
var desc22 = new ActionDescriptor();
var idnull = charIDToTypeID( "null" );
var ref5 = new ActionReference();
var idLyr = charIDToTypeID( "Lyr " );
var idOrdn = charIDToTypeID( "Ordn" );
var idTrgt = charIDToTypeID( "Trgt" );
ref5.putEnumerated( idLyr, idOrdn, idTrgt );
desc22.putReference( idnull, ref5 );
var idT = charIDToTypeID( "T " );
var desc23 = new ActionDescriptor();
var idUsrM = charIDToTypeID( "UsrM" );
desc23.putBoolean( idUsrM, bool ); // set here
var idLyr = charIDToTypeID( "Lyr " );
desc22.putObject( idT, idLyr, desc23 );
executeAction( idsetd, desc22, DialogModes.NO );
}
