How to select mulitple artlayers simultaneously?
Can somenoe help me out?

Bonjour

By using ScriptingListenerJS.log - AddToSelection

Something like this:
Code: Select allactiveDocument.activeLayer = activeDocument.layers[3]; // calque actif
SelCalc1 = activeDocument.layers[1].name; // pour ajout
SelCalc2 = activeDocument.layers[2].name;  // idem

addCalc(SelCalc1);
addCalc(SelCalc2);


function addCalc( selCalc )
{
    var idslct = charIDToTypeID( "slct" );
    var desc7 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
    var ref5 = new ActionReference();
    var idLyr = charIDToTypeID( "Lyr " );
    ref5.putName( idLyr, selCalc );
    desc7.putReference( idnull, ref5 );
    var idselectionModifier = stringIDToTypeID( "selectionModifier" );
    var idselectionModifierType = stringIDToTypeID( "selectionModifierType" );
    var idaddToSelection = stringIDToTypeID( "addToSelection" );
    desc7.putEnumerated( idselectionModifier, idselectionModifierType, idaddToSelection );
    var idMkVs = charIDToTypeID( "MkVs" );
    desc7.putBoolean( idMkVs, false );
    executeAction( idslct, desc7, DialogModes.NO );
}

Tks txuku
The codes works well if the layer name is unique.
The codes manipulate the layers by their name,if there are different layers in different layersets but with same name.The codes above can't work as you wish.

Don’t you mean

You have not explained how you want to identify the layers.

Either Paul or Mike (or both) have provided cows to select multiple layers via the index.
Code: Select all// by mike hale, via paul riggott;
// http://forums.adobe.com/message/1944754#1944754
function selectLayerByIndex(index,add){
add = undefined ? add = false:add
var ref = new ActionReference();
    ref.putIndex(charIDToTypeID("Lyr "), index);
    var desc = new ActionDescriptor();
    desc.putReference(charIDToTypeID("null"), ref );
       if(add) desc.putEnumerated( stringIDToTypeID( "selectionModifier" ), stringIDToTypeID( "selectionModifierType" ), stringIDToTypeID( "addToSelection" ) );
      desc.putBoolean( charIDToTypeID( "MkVs" ), false );
   try{
    executeAction(charIDToTypeID("slct"), desc, DialogModes.NO );
}catch(e){
alert(e.message);
}
};

Thank you very much,pfaffenbichle.I just want to know if there is a flexiable way.Actually ,txuku's code works well for me .
tks you all.

I was just playing around with this, and I though that the layer index was unique to that layer and didn't change, but I moved some layers around and the index changes. Is there some way to get a unique identifier for a layer that doesn't change, so that you can reselect that and multiple other layer after they've been moved?

I these are some functions you can use to get the selected layers Id and select multiple by Id.

Code: Select allfunction getSelectedLayersIds(){// get the selected layers identifiers
  //( these id's are unique and they will not change if the layer name is changed or it's position in the layers editor will change)
   var idxs = getSelectedLayersIdx();// first get the indexes
   var selectedLayersIds = [];
  //for each index get the layer id
   for( var i=0;i<idxs.length;i++){
      selectedLayersIds.push(getIdfromIdx(idxs));
   }
   return selectedLayersIds;
}
function hasBackground(){// function to check if there is a background layer
    var res = undefined;
    try{
        var ref = new ActionReference();
        ref.putProperty( charIDToTypeID("Prpr") , charIDToTypeID("Nm  "));
        ref.putIndex( charIDToTypeID("Lyr "), 0 );
        executeActionGet(ref).getString(charIDToTypeID("Nm  ") );
        res = true;
    }catch(e){ res = false}
    return res;
}
function getIdfromIdx( idx ){// get the id from index
   var ref = new ActionReference();
   ref.putIndex(charIDToTypeID('Lyr '), idx);
    var desc = executeActionGet(ref);
       desc = desc.getInteger(charIDToTypeID("LyrI"));
       return desc;
}

function getSelectedLayersIdx(){// get the selected layers index( positon in layer editor)
     var selectedLayers = new Array;
     var ref = new ActionReference();
     ref.putEnumerated( charIDToTypeID('Dcmn'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
     var desc = executeActionGet(ref);
     var add = 1;
     if(hasBackground()){alert('hBck');add = 0}
     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++){
               selectedLayers.push(  (desc.getReference( i ).getIndex()) + add);
          }
     }else{
          var ref = new ActionReference();
          ref.putProperty( charIDToTypeID('Prpr') , charIDToTypeID( 'ItmI' ));
          ref.putEnumerated( charIDToTypeID('Lyr '), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
          srs = hasBackground()?executeActionGet(ref).getInteger(charIDToTypeID( 'ItmI' ))-1:executeActionGet(ref).getInteger(charIDToTypeID( 'ItmI' ));
          selectedLayers.push( srs);
     }
     return selectedLayers;
}

function doesIdExists( id ){// function to check if the id exists
   var res = true;
   var ref = new ActionReference();
   ref.putIdentifier(charIDToTypeID('Lyr '), id);
    try{var desc = executeActionGet(ref)}catch(err){res = false};
    return res;
}
function multiSelectByIDs(ids) {
  if( ids.constructor != Array ) ids = [ ids ];
    var layers = new Array();
    var id54 = charIDToTypeID( "slct" );
    var desc12 = new ActionDescriptor();
    var id55 = charIDToTypeID( "null" );
    var ref9 = new ActionReference();
    for (var i = 0; i < ids.length; i++) {
       if(doesIdExists(ids) == true){// a check to see if the id stil exists
           layers = charIDToTypeID( "Lyr " );
           ref9.putIdentifier(layers, ids);
       }
    }
    desc12.putReference( id55, ref9 );
    var id58 = charIDToTypeID( "MkVs" );
    desc12.putBoolean( id58, false );
    executeAction( id54, desc12, DialogModes.NO );

Thanks, this does work. I guess the script I was using just got the idx and not the id.
