Can someone help me with a script which will search all layers in Active Documnet for a specific name and if found make that the active Layer or Return an Alert if not found.

Thanks

Reading your posting again:

try {
(ref1 = new ActionReference()).putName(stringIDToTypeID('layer'), "Canvas" ); // replace Canvas with your layer name
(desc1 = new ActionDescriptor()).putReference(stringIDToTypeID('null'), ref1)
executeAction(stringIDToTypeID('select'), desc1, DialogModes.NO);
} catch (e) {
    alert("Sorry, this layername does not exists");
}

Did you tried your own code in documents with layer sets?

Ah...

Just tried my own code with Layer Sets and it Failed 😞

To process all layers names with DOM code you would need to use recursion. In that Process you could break when you find the first layer with the name or continue the process counting the number of layer or creating an array of layers with the name. A count of 0 = not found . The Action manage code is select layer Name. Which will select the layer with the name closest to the bottom of the layer stack. If there no such layer the Active layer would not be changed from what it was.

There are some differences between Action manager Layer kinds and DOM Layer Kind. For example all shape layers are fill layers but all fill layers are not shape layers. DOM has no Layer Kind Shape where Action Manager has a Shape kind. Many Scripts need to use some action manager code to script some thing Adobe DOM does not cover all of Photoshop features.

Here is a LayerStack.jsx that views layers from both kind of view don't try the script on a document with more the 20 layers.

// 2019, use it at your own risk;

	//Action Manager layerKind seems to be like this. 
 	var Doclayerkind = [
	"Pixel", 
	"Adjustment", 
	"Text",

	"Smartobject",

Reading your posting again:

try {
(ref1 = new ActionReference()).putName(stringIDToTypeID('layer'), "Canvas" ); // replace Canvas with your layer name
(desc1 = new ActionDescriptor()).putReference(stringIDToTypeID('null'), ref1)
executeAction(stringIDToTypeID('select'), desc1, DialogModes.NO);
} catch (e) {
    alert("Sorry, this layername does not exists");
}

Thank You

This also seems to work having read a bit deeper into the Scripting Manual

try {
  app.activeDocument.activeLayer = app.activeDocument.artLayers.getByName("Master Layer");
  }
catch (e) {
  alert("Not Found");
  }

Guess its just a personal Preference as to which way to do it

Hi @ian-barber,

you could try:

(ref1 = new ActionReference()).putName(stringIDToTypeID('layer'), "Canvas" ); // replace Canvas with your layer name
(desc1 = new ActionDescriptor()).putReference(stringIDToTypeID('null'), ref1)
executeAction(stringIDToTypeID('select'), desc1, DialogModes.NO);

If that works for you

have fun

If the script finds layers with the name would you also want the nuuber of layers with the name or knowing that there is at least one is all you need to know. getByName

knowing that there is at least one would probably be sufficient
