Answer 1

i try to change by Getting Channel Information
thx Michael L Hale
change to:
function getProperty( psClass, psKey, index ){// integer:Class, integer:key
    var ref = new ActionReference();
    if( psKey != undefined ) ref.putProperty( charIDToTypeID( "Prpr" ), psKey );
    if(index != undefined ){
        ref.putIndex( psClass, index );
    }else{
        ref.putEnumerated( psClass , charIDToTypeID( "Ordn" ), charIDToTypeID( "Trgt" ) );
    try{
        var desc = executeActionGet(ref);
    }catch(e){ return; }// return on error
    if(desc.count == 0) return;// return undefined if property doesn't exists
    var dataType = desc.getType(psKey);
    switch(dataType){// not all types supported - returns undefined if not supported
        case DescValueType.INTEGERTYPE:
            return desc.getInteger(psKey);
            break;
        case DescValueType.ALIASTYPE:
            return desc.getPath(psKey);
            break;
        case DescValueType.BOOLEANTYPE:
            return desc.getBoolean(psKey);
            break;
        case DescValueType.BOOLEANTYPE:
            return desc.getBoolean(psKey);
            break;
        case DescValueType.UNITDOUBLE:
            return desc.getUnitDoubleValue(psKey);
            break;
        case DescValueType.STRINGTYPE:
            return desc.getString(psKey);
            break;
        case  DescValueType.OBJECTTYPE:
            return desc.getObjectValue(psKey);
            break;
        case  DescValueType.LISTTYPE:
            return desc.getList(psKey);
            break;
        case  DescValueType.ENUMERATEDTYPE:
            return desc.getEnumerationValue(psKey);
            break;
var channelCount = app.activeDocument.channels.length;
var channelNames = [];
for(var channelIndex=1;channelIndex<=channelCount;channelIndex++){  
    var channelNames =getProperty(charIDToTypeID("Chnl"),charIDToTypeID("ChnN"),channelIndex);
// =======================================================
if(channelIndex==1){
else if(channelIndex==2){
else if(channelIndex==3){
else if(channelIndex==4){
else if(channelIndex>=5){
var idslct = charIDToTypeID( "slct" );
    var desc329 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
        var ref246 = new ActionReference();
        var idChnl = charIDToTypeID( "Chnl" );
        ref246.putName( idChnl, ""+channelNames);
    desc329.putReference( idnull, ref246 );
executeAction( idslct, desc329, DialogModes.NO );
// =======================================================
var idsetd = charIDToTypeID( "setd" );
    var desc330 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
        var ref247 = new ActionReference();
        var idChnl = charIDToTypeID( "Chnl" );
        var idOrdn = charIDToTypeID( "Ordn" );
        var idTrgt = charIDToTypeID( "Trgt" );
        ref247.putEnumerated( idChnl, idOrdn, idTrgt );
    desc330.putReference( idnull, ref247 );
    var idT = charIDToTypeID( "T   " );
        var desc331 = new ActionDescriptor();
        var idNm = charIDToTypeID( "Nm  " );
        desc331.putString( idNm, """"""+channelIndex-4 );
    var idSCch = charIDToTypeID( "SCch" );
    desc330.putObject( idT, idSCch, desc331 );
executeAction( idsetd, desc330, DialogModes.NO );
if spot channel name is number such as spot channel sequence: 2,1,3,6,8,9...can't success!...other success!
