Finding documents by name in Photoshop

When working with multiple open Photoshop files, the usual method of using getByName for layers or history states doesn't seem to work for documents.

var srcDoc = app.Documents.getByName("Gwen_Stefani"); // no success

Is this the correct approach?

A workaround involves looping through the documents array until the required document is found:

getDocumentByName("Gwen_Stefani");


function getDocumentByName(docname)
{
  for (var i = 0; i < documents.length; i++)
  {
    var someDoc = docname.replace(/\..+$/, "");
    if (someDoc.toLowerCase() == docname.toLowerCase())
    {
      alert(someDoc);
      app.activeDocument = documents[i];
    }
  }
}

Answer №1

Feeling uncertain? Just refer to the scripting reference (p 104):

https://i.sstatic.net/48Anp.png

var srcDoc = documents.getByName("Gwen_Stefani");
activeDocument = srcDoc;

You can also activate documents by their ID for more reliability:

// function to select a document based on provided ID
function selectByID(id) {
    var desc = new ActionDescriptor();
    var ref = new ActionReference();
    ref.putIdentifier(charIDToTypeID("Dcmn"), id);
    desc.putReference(charIDToTypeID("null"), ref);
    executeAction(charIDToTypeID("slct"), desc, DialogModes.NO);
}

// function to get the ID of the active document
function getDocID() {
    var ref = new ActionReference();
    ref.putProperty(stringIDToTypeID("property"), stringIDToTypeID("documentID"));
    ref.putEnumerated(charIDToTypeID("Dcmn"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));
    var desc = executeActionGet(ref);
    return desc.getInteger(stringIDToTypeID("documentID"));
}
