How do I reverse this Layers Naming Loop?

I cannot figure out how to reverse a loop. I need my layers to be named numerically in the opposite order (where 0 is on the bottom instead of the top). Any help would be appreciated. I'd really like it to number everything from 1 rather than 0 but I'll figure that out later.

//-------------------------------------------------------------------- START Name Layers Numerically

#target photoshop

for (var i = 0; i < app.documents.length; i++) {
var targetDocument = app.documents[i];
var layerCount = targetDocument.layers.length;

for (var j = layerCount - 1; j >= 0; j--) {
var targetLayer = targetDocument.layers[j];
var layerName = new String(targetLayer.name);

if (layerName.indexOf(targetLayer.name) == 0) {
targetDocument.layers[j].name = j
}

}
}

//-------------------------------------------------------------------- END Name Layers Numerically

Correct answer Manan Joshi

Try the following

for (var i = 0; i < app.documents.length; i++) {
	activeDocument = app.documents[i];
	var layerCount = activeDocument.layers.length;
	var idx = 0
	for (var j = layerCount - 1; j >= 0; j--)
		activeDocument.layers[j].name = idx++
}

Edit :- I tested the code and found that we can set the layer name only if the document is active so have added that fix, also i see in the version you posted there is no need for the if statement as you are practically matching the same string which will result in a true result everytime. Have changed the code accordingly

So the version below will cater to groups as well as, it will rename the layers with 0 at the bottom

function renameLayer(doc, layerCol, idx)
{
	activeDocument = doc;
	var layerCount = layerCol.length;
	for (var j = layerCount - 1; j >= 0; j--)
	{
		var l = layerCol[j]
		if(l.typename != "LayerSet")
			l.name = idx.i++
		else
			renameLayer(doc, layerCol[j].layers, idx)
	}
}

for (var i = 0; i < app.documents.length; i++)
	renameLayer(app.documents[i], app.documents[i].layers, {"i" :0})

I may be right but I do not know scripting I just hack at it Often I steal others code and whack away at it make it submit to my will. I can not even type. I need a starting point.

Fairly Tail time.

Once upon a time I had some interest in Photoshop Layer stack and layers in the stack and layer kinds. So I took out my wip and whacked some code but at last I do not remember what I did or how I did it my memory is not what it use to be. What remains are two script that seem to look at Photoshop's Layer Stack in Layer stack order and spite out some information about the stack. LayersStack.jsx and LayrsStackLayers.jsx they look something like this.

Wait wait something is coming back to me I seem to remember that Action Manager had some array of its layer Kinds and DOM had it array of its Layer kinds. Like Action Manager has a ]]Shape layer Kinds but DOM has no Layer Kind Shape but sill manages to have more Layer Kinds than Action Manager go figure.

This will process all layers they will not be processes in stack order

var allLayers = "";
processArtLayers(activeDocument) 
alert(allLayers, "Layers");
function processArtLayers(obj) {  
    for( var i = obj.artLayers.length-1; 0 <= i; i--) {/* alert(obj.artLayers[i]); */processLayers(obj.artLayers[i])}  
    for( var i = obj.layerSets.length-1; 0 <= i; i--) {/* alert(obj.layerSets[i]); */processArtLayers(obj.layerSets[i])} // Process Layer Set Layers  
} 
function processLayers(layer) { 
	allLayers = allLayers + "ID " + layer.id + ", " + layer.name + ", " + layer.kind + "\n";
	switch (layer.kind){
	default : break; // none process layer types catch all
	}
}

if any open document has a layer groups your script will not process all the layers. You Script is only processing top level Layers and Layer groups no layer in a group will be precessed. You need to use recursion to process layers in layer groups.

#target photoshop

for (var i = 0; i < app.documents.length; i++) {
	var targetDocument = app.documents[i];
	var layerCount = targetDocument.layers.length;
	var LayerProcessOrder="Layer Processed\n";
	for (var j = layerCount - 1; j >= 0; j--) {
		var targetLayer = targetDocument.layers[j];
		LayerProcessOrder = LayerProcessOrder + targetLayer.name + "\n";
		var layerName = new String(targetLayer.name);
		if (layerName.indexOf(targetLayer.name) == 0) {
			targetDocument.layers[j].name = j
		}
	}
	alert(LayerProcessOrder);
}

Yes JJMack you are right, i just edited what the OP had already done, if needed this can be implemented as well. I would wait for the OP's comment before adding in a new snippet of code, being lazy here what if he does not need it 😛

That is beautiful. Thank you for your help. I've read your notes and am digesting it. Much appreciated.

Try the following

for (var i = 0; i < app.documents.length; i++) {
	activeDocument = app.documents[i];
	var layerCount = activeDocument.layers.length;
	var idx = 0
	for (var j = layerCount - 1; j >= 0; j--)
		activeDocument.layers[j].name = idx++
}
