Thank you in advance!!!

JavaScript:
function getAllShapeLayersData() {
var lyrs = [];
try {
activeDocument.backgroundLayer;
var layers = 0
}
catch (e) {
var layers = 1;
};
while (true) {
ref = new ActionReference();
ref.putIndex(charIDToTypeID('Lyr '), layers);
try {
var desc = executeActionGet(ref);
}
catch (err) {
break;
}
var lyr = {};
lyr.type = desc.getInteger(stringIDToTypeID("layerKind"));
lyr.name = desc.getString(charIDToTypeID("Nm "));
lyr.id = desc.getInteger(stringIDToTypeID("layerID"));
if (lyr.type == 4) { // shape layer
var adj = desc.getList(stringIDToTypeID("adjustment")).getObjectValue(0);
if (adj.hasKey(stringIDToTypeID("color"))) {
var curColor = new SolidColor();
curColor.rgb.red = adj.getObjectValue(stringIDToTypeID("color")).getUnitDoubleValue(stringIDToTypeID("red"));
curColor.rgb.green = adj.getObjectValue(stringIDToTypeID("color")).getUnitDoubleValue(stringIDToTypeID("grain"));
curColor.rgb.blue = adj.getObjectValue(stringIDToTypeID("color")).getUnitDoubleValue(stringIDToTypeID("blue"));
lyr.color = curColor;
lyrs.push(lyr);
}
}
layers++;
}
return lyrs
}
