Script Help - Find layer that contains text & Errors if cannot find

[christopherd53564434]

I'm looking for a script that (1) finds a layer that contains specific text, then (2) provides an error message if no layer can be found.

I've already found the first portion in a previous post but i'm not familiar with script writing to understand how to prompt an error message if else. See below for the first portion that's working but needs an if else prompt added. For context, the text i'm searching for is "Grain -"

s2t = stringIDToTypeID;
(ref = new ActionReference()).putProperty(s2t('property'), p = s2t('numberOfLayers'));
ref.putEnumerated(s2t('document'), s2t('ordinal'), s2t('targetEnum'));
var len = executeActionGet(ref).getInteger(p);
for (var i = 1; i <= len; i++) {
    (ref = new ActionReference()).putProperty(s2t('property'), p = s2t('name'));
    ref.putIndex(s2t('layer'), i);
    if ((/Grain -/i).test(executeActionGet(ref).getString(p))) {
        (ref = new ActionReference()).putProperty(s2t('property'), p = s2t('layerID'));
        ref.putIndex(s2t('layer'), i);
        (r = new ActionReference()).putIdentifier(s2t("layer"), executeActionGet(ref).getInteger(p));
        (d = new ActionDescriptor()).putReference(s2t("target"), r);
        executeAction(s2t("select"), d, DialogModes.NO);
        break;
    }
}

This is a variant on a production script I use. I do have one that exports text layers to a file, that can be opened in Excel and searched.

This one does as you want and alerts if text isn't found. Just change the hard-coded variable.

textChecker();
function textChecker(){
    if(documents.length > 0){
        var originalDialogMode = app.displayDialogs;
        app.displayDialogs = DialogModes.ERROR;
        try{
            for(var j = 0; j < documents.length; j++){
                var docRef = documents[j];
                var sets = docRef.layerSets;
                var searchTerm = 'test';
                for(var l = 0; l < sets.length; l++){
                    for(var k = 0; k < sets[l].artLayers.length; k++){
                        var SetLayerRef = sets[l].artLayers[k];
                        if(SetLayerRef.kind == LayerKind.TEXT){
                            var SetlayerText = SetLayerRef.textItem.contents;
                            if(SetlayerText.search(searchTerm) == -1){
                                alert('Not found in ' + SetLayerRef.name);
                                }
                            }
                        }
                    }
                for(var i = 0; i < docRef.artLayers.length; i++){
                    var LayerRef = docRef.artLayers[i];
                    if(LayerRef.kind == LayerKind.TEXT){
                        var layerText = LayerRef.textItem.contents;
                        if(layerText.search(searchTerm) == -1){
                            alert('Not found in ' + LayerRef.name);
                            }
                        }
                    }
                }
            }
        catch(e){
            alert(e + e.line);
            }
        app.displayDialogs = originalDialogMode;

    }

I think that all you need to do is add an "else" to the "if" block...

s2t = stringIDToTypeID;
(ref = new ActionReference()).putProperty(s2t('property'), p = s2t('numberOfLayers'));
ref.putEnumerated(s2t('document'), s2t('ordinal'), s2t('targetEnum'));
var len = executeActionGet(ref).getInteger(p);
for (var i = 1; i <= len; i++) {
    (ref = new ActionReference()).putProperty(s2t('property'), p = s2t('name'));
    ref.putIndex(s2t('layer'), i);
    if ((/Grain -/i).test(executeActionGet(ref).getString(p))) {
        (ref = new ActionReference()).putProperty(s2t('property'), p = s2t('layerID'));
        ref.putIndex(s2t('layer'), i);
        (r = new ActionReference()).putIdentifier(s2t("layer"), executeActionGet(ref).getInteger(p));
        (d = new ActionDescriptor()).putReference(s2t("target"), r);
        executeAction(s2t("select"), d, DialogModes.NO);
        break;
    } else {
        app.beep();
        alert("Match not found!");
    }
}

This would select the Type Layers containing a certain text.
