如何在 Photoshop 脚本中抑制弹出消息 "No pixels are selected."

Question

我有一个脚本可以遍历文档并检查每一层是否有空白图层蒙版，然后删除该图层蒙版。

我不确定是否有比获取选区并反转它更好的方法来检查图层蒙版是否为空白。

反转后，如果没有选区，Photoshop会弹出警告信息"No pixels are selected."

如何在不检查的情况下避免出现此消息 "Don't show again"？

for ( var a =0; a<activeDocument.artLayers.length; a++ ){
    activeDocument.activeLayer = activeDocument.artLayers[a];
    checkLayerMask();
};

function checkLayerMask() {
    // has layer mask
    var ref = new ActionReference();
    ref.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
    var desc = executeActionGet(ref);
    var hasLayerMask = desc.hasKey(charIDToTypeID("UsrM")); // bool

    if (hasLayerMask) {
        // make layer mask active
        var desc = new ActionDescriptor();
        var ref = new ActionReference();
        ref.putEnumerated( charIDToTypeID( "Chnl" ), charIDToTypeID( "Chnl" ), charIDToTypeID( "Msk " ) );
        desc.putReference( charIDToTypeID( "null" ),  ref );
        desc.putBoolean( charIDToTypeID( "MkVs" ), false );
        executeAction( charIDToTypeID( "slct" ), desc, DialogModes.NO );

        // get selection from layer mask
        var desc = new ActionDescriptor();
        var ref = new ActionReference();
        ref.putProperty( charIDToTypeID( "Chnl" ), charIDToTypeID( "fsel" ) );
        desc.putReference( charIDToTypeID( "null" ), ref );
        var ref = new ActionReference();
        ref.putEnumerated( charIDToTypeID( "Chnl" ), charIDToTypeID( "Ordn" ), charIDToTypeID( "Trgt" ) );
        desc.putReference( charIDToTypeID( "T   " ), ref );
        executeAction( charIDToTypeID( "setd" ), desc, DialogModes.NO );

        // invert selection
        activeDocument.selection.invert(); 
        try { activeDocument.selection.bounds}
        catch(e) {
            // delete active layer mask
            var desc = new ActionDescriptor();
            var ref = new ActionReference();
            ref.putEnumerated( charIDToTypeID( "Chnl" ), charIDToTypeID( "Ordn" ), charIDToTypeID( "Trgt" ) );
            desc.putReference( charIDToTypeID( "null" ), ref );
            executeAction( charIDToTypeID( "Dlt " ), desc, DialogModes.NO );
        };
    }
    app.activeDocument.selection.deselect();
};

将 DialogModes 设置为 NO 的 AM 命令不会生成此消息：

executeAction(charIDToTypeID('Invs'), undefined, DialogModes.NO);
