How to use a script to find smart objects by name and replace images in that smart object

I tried the code below, it works but I want to hide the old layers in the smart object to avoid having 2 images overlap like in the photo (Layer smart object name "sm3" is overlapping 2 images and I want to delete it or hide old photos)
 
 
// Set the path to the input folder
var inputFolderPath = "C:\\Users\\Admin\\Downloads\\avt";

// Get a reference to the active document
var doc = app.activeDocument;

// Loop through each smart object layer and place the corresponding image
for (var i = 1; i <= 3; i++) {
    var smartObjName = "sm" + i;
    var smartObj = doc.layers.getByName(smartObjName);

    // Check if the smart object layer was found
    if (!smartObj) {
        alert(i + "\nCould not find layer '" + smartObjName + "'.");
        continue;
    }

    // Activate the smart object layer and open the contents
    doc.activeLayer = smartObj;
    //  replaceContents (inputFolderPath + "/artwork" + i + ".jpg");
    // Get a reference to the active document and place the corresponding image
    var subDoc = openSmartObject();
    var inputFilePath = inputFolderPath + "/a (" + i + ").png";
    var inputImgFile = new File(inputFilePath);
    placeScaleRotateFile(inputFilePath, 0, 0, 100, 100, 0)
    // Close and save the smart object contents
    subDoc.close(SaveOptions.SAVECHANGES);
};

// Close the original document without saving
//doc.close(SaveOptions.DONOTSAVECHANGES);
////// replace contents //////
function replaceContents(theName) {
    var idplacedLayerReplaceContents = stringIDToTypeID("placedLayerReplaceContents");
    var desc244 = new ActionDescriptor();
    var idnull = charIDToTypeID("null");
    desc244.putPath(idnull, new File(theName));
    executeAction(idplacedLayerReplaceContents, desc244, DialogModes.NO);
};
////// open smart object //////
function openSmartObject() {
    var desc2 = new ActionDescriptor();
    executeAction(stringIDToTypeID("placedLayerEditContents"), desc2, DialogModes.NO);
    return activeDocument;
};
////// place //////
function placeScaleRotateFile(file, xOffset, yOffset, theXScale, theYScale, theAngle) {
    var desc5 = new ActionDescriptor();
    desc5.putPath(charIDToTypeID("null"), new File(file));
    desc5.putEnumerated(charIDToTypeID("FTcs"), idQCSt = charIDToTypeID("QCSt"), charIDToTypeID("Qcsa"));
    var idOfst = charIDToTypeID("Ofst");
    var desc6 = new ActionDescriptor();
    var idPxl = charIDToTypeID("#Pxl");
    desc6.putUnitDouble(charIDToTypeID("Hrzn"), idPxl, xOffset);
    desc6.putUnitDouble(charIDToTypeID("Vrtc"), idPxl, yOffset);
    var idOfst = charIDToTypeID("Ofst");
    desc5.putObject(idOfst, idOfst, desc6);
    var idPrc = charIDToTypeID("#Prc");
    desc5.putUnitDouble(charIDToTypeID("Wdth"), idPrc, theYScale);
    desc5.putUnitDouble(charIDToTypeID("Hght"), idPrc, theXScale);
    desc5.putUnitDouble(charIDToTypeID("Angl"), charIDToTypeID("#Ang"), theAngle);
    desc5.putBoolean(charIDToTypeID("Lnkd"), false);
    executeAction(charIDToTypeID("Plc "), desc5, DialogModes.NO);
    return app.activeDocument.activeLayer;
};

The following code will ensure that only the top layer is active (optional?) and visible and that all other top-level layers are invisible:

 

try {
    // Ensure that the top layer is active/selected, even if no layers are currently selected
    activeDocument.activeLayer.link(activeDocument.activeLayer);
    // Set the top layer's visibility to off
    app.activeDocument.layers[0].visible = false;
    // Toggle off the visibility of all other layers except the top layer
    var s2t = function (s) {
        return app.stringIDToTypeID(s);
    };
    var descriptor = new ActionDescriptor();
    var list = new ActionList();
    var reference = new ActionReference();
    reference.putEnumerated(s2t("layer"), s2t("ordinal"), s2t("targetEnum"));
    list.putReference(reference);
    descriptor.putList(s2t("null"), list);
    descriptor.putBoolean(s2t("toggleOptionsPalette"), true);
    executeAction(s2t("show"), descriptor, DialogModes.NO);
} catch (e) {
    alert("Error!" + "\r" + e + ' ' + e.line);
}

 

 

If you are not concerned about having the top layer active/selected, you can remove the first line from the previous code or use the following:

 

 

// Make all layers invisible
for (var i = 0; i < app.activeDocument.layers.length; i++) {
    app.activeDocument.layers[i].visible = false;
}
// Set the top layer's visibility to on
app.activeDocument.layers[0].visible = true;

 

 

Or:

 

 

for (var i = 0; i < app.activeDocument.layers.length; i++) {
    if (app.activeDocument.layers[i] != app.activeDocument.layers[0]) {
        app.activeDocument.layers[i].visible = false;
    }
}

How did the suggested code work for you?

Here in the following section of code, I have added an alert to pause the script so that you can screenshot the layers panel to show which layers you are talking about:

 

// Activate the smart object layer and open the contents
doc.activeLayer = smartObj;
//  replaceContents (inputFolderPath + "/artwork" + i + ".jpg");
// Get a reference to the active document and place the corresponding image
var subDoc = openSmartObject();
var inputFilePath = inputFolderPath + "/a (" + i + ").png";
var inputImgFile = new File(inputFilePath);
placeScaleRotateFile(inputFilePath, 0, 0, 100, 100, 0)
alert("Take a screenshot of the layers panel of the open smart object")!
// Close and save the smart object contents
subDoc.close(SaveOptions.SAVECHANGES);

    I tested it and it shows like this. Which code helps me hide or delete "Layer 1" in that smart object?
