Correct answer Muppet Mark

it show this error


That will learn me to be lazy and copy/paste/edit in the browser window… 

var doc = app.activeDocument;
if ( doc.pathItems.length > 0 ) {
  
          doc.pathItems[0].makeSelection( 0, true, SelectionType.REPLACE );
  
          doc.pathItems[0].deselect();
} else {
          try {
  
                    doc.selection.load( doc.channels.getByName('Alpha 1'), SelectionType.REPLACE, false );
  
          } catch(e) {}
  
};

Would have thought you could have sorted that mistake thou…

Depending on the state of your documents you may be able to use something like this…

var doc = app.activeDocument;
if ( doc.pathItems.length > 0 ) {
  
     doc.pathItems[0].makeSelection( 0, true, SelectionType.REPLACE );
  
     doc.pathItems[0].deselect();
} else {
  
     if ( doc.channels[ doc.channels.length-1 ].kind == ChannelType.SELECTEDAREA ) {
  
          doc.selection.load( doc.channels[ doc.channels.length-1 ], SelectionType.REPLACE, false );
  
     }
  
};

It should use a path first then if no paths the last channel… Otherwise it will do nothing…

Did you try it… This would look for the alpha by name rather than position…

var doc = app.activeDocument;
if ( doc.pathItems.length > 0 ) {
  
     doc.pathItems[0].makeSelection( 0, true, SelectionType.REPLACE );
  
     doc.pathItems[0].deselect();
} else {
          try {
  
               doc.selection.load( doc.channels.getByName('Alpha 1'), SelectionType.REPLACE, false );
  
          } catch(e) {}
     }
  
};
