How would I hide error alerts in this script?

[kenf]

Hello, how would I hide or automatically dismiss error alerts in this script in case layer 1 or layer 2 don't exist? Thank you.

Code: Select all

hideCheckLayers=function() {
  // Hide
  function step1(enabled, withDialog) {
    if (enabled != undefined && !enabled)
      return;
    var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
    var desc1 = new ActionDescriptor();
    var list1 = new ActionList();
    var ref1 = new ActionReference();
    ref1.putName(cTID('Lyr '), "layer 1");
    list1.putReference(ref1);
    desc1.putList(cTID('null'), list1);
    executeAction(cTID('Hd  '), desc1, dialogMode);
  };

  // Hide
  function step2(enabled, withDialog) {
    if (enabled != undefined && !enabled)
      return;
    var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
    var desc1 = new ActionDescriptor();
    var list1 = new ActionList();
    var ref1 = new ActionReference();
    ref1.putName(cTID('Lyr '), "layer 2");
    list1.putReference(ref1);
    desc1.putList(cTID('null'), list1);
    executeAction(cTID('Hd  '), desc1, dialogMode);
  };

  step1();      // Hide
  step2();      // Hide
};

Might be a bit late, but this should to the trick;

Code: Select all

hideCheckLayers=function() {
  // Hide
  function step1(enabled, withDialog) {
    if (enabled != undefined && !enabled)
      return;
    var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
    var desc1 = new ActionDescriptor();
    var list1 = new ActionList();
    var ref1 = new ActionReference();
    ref1.putName(cTID('Lyr '), "layer 1");
    list1.putReference(ref1);
    desc1.putList(cTID('null'), list1);
    executeAction(cTID('Hd  '), desc1, dialogMode);
  };

  // Hide
  function step2(enabled, withDialog) {
    if (enabled != undefined && !enabled)
      return;
    var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
    var desc1 = new ActionDescriptor();
    var list1 = new ActionList();
    var ref1 = new ActionReference();
    ref1.putName(cTID('Lyr '), "layer 2");
    list1.putReference(ref1);
    desc1.putList(cTID('null'), list1);
    executeAction(cTID('Hd  '), desc1, dialogMode);
  };
	
	try {																								//Tries;
		step1();      // Hide
	} catch(error) {																					//Ignores errors
	}
	try {																								//Tries;
		step2();      // Hide
	} catch(error) {																					//Ignores errors
	}

};
