选中多个图层
方法一：
select_layer("图层 2");
select_layer("图层 5", true);
function select_layer(nm, add)
{
try {
var r = new ActionReference();
r.putName(stringIDToTypeID("layer"), nm);
var d = new ActionDescriptor();
d.putReference(stringIDToTypeID("null"), r);
if (add == true) d.putEnumerated(stringIDToTypeID("selectionModifier"), stringIDToTypeID("selectionModifierType"), stringIDToTypeID("addToSelection"));
executeAction(stringIDToTypeID("select"), d, DialogModes.NO);
}
catch (e) { alert(e); throw(e); }
}
方法二：
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[i]) == true){// a check to see if the id stil exists
layers[i] = charIDToTypeID( "Lyr " );
ref9.putIdentifier(layers[i], ids[i]);
}
}
desc12.putReference( id55, ref9 );
var id58 = charIDToTypeID( "MkVs" );
desc12.putBoolean( id58, false );
executeAction( id54, desc12, DialogModes.NO );
}
var ids=new Array;
ids.push(2);
ids.push(5);
ids.push(6);
multiSelectByIDs(ids);
