javascript - Changing selected text layers language with photoshop script -

though managed put functional script change dictionary language of selected layers together, it's not quite need yet.

i'm retrieving index of selected layers, using them layer names—it's problematic part—then working magic change language based on option chosen in custom dialog box display.

the use of layers names half-assed solution, need precision, need able change language based on layer id or index. not script prone names conflicts have no idea of selected layers be, if on root of document or inside 5 groups stack.

here current code:

the main function

function main() {     // create window language selection , retrieve selected value     var lang = createwindow();     // retrieve selected layers    var selectedlayers = getselectedlayersidx();     // @ each entry , change language when possible    for(var in selectedlayers){         try {            setlangbyindex(number( selectedlayers[a]), lang );         } catch(err) {   }    } } 

(createwindow returns lang value, skipping that)

mike's idx

function  getselectedlayersidx(){     var selectedlayers = new array;     var ref = new actionreference();     ref.putenumerated( charidtotypeid('dcmn'), charidtotypeid('ordn'), charidtotypeid('trgt') );     var desc = executeactionget(ref);     if( desc.haskey( stringidtotypeid( 'targetlayers' ) ) ) {         desc = desc.getlist( stringidtotypeid( 'targetlayers' ));         var c = desc.count         var selectedlayers = new array();         for(var i=0;i<c;i++) {             try{                 activedocument.backgroundlayer;                 selectedlayers.push(  desc.getreference( ).getindex() );             } catch(e) {                 selectedlayers.push(  desc.getreference( ).getindex()+1 );             }         }     } else {         var ref = new actionreference();         ref.putproperty( charidtotypeid('prpr') , charidtotypeid( 'itmi' ));         ref.putenumerated( charidtotypeid('lyr '), charidtotypeid('ordn'), charidtotypeid('trgt') );         try {             activedocument.backgroundlayer;             selectedlayers.push( executeactionget(ref).getinteger(charidtotypeid( 'itmi' ))-1);         } catch(e) {             selectedlayers.push( executeactionget(ref).getinteger(charidtotypeid( 'itmi' )));         }     }     return selectedlayers; } 

the function sets language

function setlangbyindex(idx, lang){     ref = new actionreference();     ref.putproperty( charidtotypeid("prpr") , charidtotypeid( "nm  " ));     ref.putindex( charidtotypeid( "lyr " ), idx );     var name = executeactionget(ref).getstring(charidtotypeid( "nm  " ));      var el = activedocument.layers.getbyname( name );     // temp quick block; must update in case of new languages      if (lang == 'pt_br' )         el.textitem.language = language.brazillianportuguese;     else if (lang == 'en_us' )         el.textitem.language = language.englishusa;     else         el.textitem.language = language.englishuk; } 

workarounds inefficiently tried:

• use adobe's script listener change language executeaction, couldn't make work. language part inside ~4 stacked descriptors (and list!). got lost , kept getting errors 8800.
• figure out how obtain object ref using idx. failed miserably.

after noticed annoying glitches related paragraph styles (the ones can define default text on ps, not js object) gave on being stubborn , stopped avoiding doing new loop through indexes array reselect layers when done.
