Fastest way to get the layers by keystring (regexp, etc)?

[Tokis]

Hi, guys!

I need to find all of the layers in the document that start with a "$".
I do this by comparing the name of each layer using regexps (see code).
But it turns out very slowly. Maybe there is a quick way to do this?

Thank U!

(sorry google translate )

Code: Select all#target photoshop

docRef = app.activeDocument;

var arrTemp= new Array(); 
for(var i=0; i<docRef.artLayers.length; i++)if(docRef.artLayers.name.match(/\$.*/) != null) arrTemp.push(docRef.artLayers);

Does this help?
It collects the names and indices of the layers instead of the Layers, the Layers can later be addressed though their indices (if the number and position of Layers get changed the indices may change, so that might necessitate using the layerID instead).

if (app.documents.length > 0) {
var myDocument = app.activeDocument;
main ();
};
