Apply basic filter to multiple values in a spreadsheet column

Question

I am working on getting filters set through Google Apps Script. From my research I have come to the conclusion that although .setVisibleValues() is listed as av

Yes. You can use splice()method. You can change this from:

var criteria = SpreadsheetApp.newFilterCriteria()
  .setHiddenValues(['One', 'Two', 'Three', 'Five', 'Six', 'Seven'])
  .build();

to:

  var sh = spreadsheet.getActiveSheet();    
  var filterRange = sh.getRange('L1:L'+sh.getLastRow()).getValues(); //Get L column values    
  var hidden = getHiddenValueArray(filterRange,["four"]); //get values except four    
  var filtercriteria = SpreadsheetApp.newFilterCriteria().setHiddenValues(hidden).build();



//flattens and strips column L values of all the values in the visible value array
function getHiddenValueArray(colValueArr,visibleValueArr){
  var flatArr = colValueArr.map(function(e){return e[0];}); //Flatten column L
  visibleValueArr.forEach(function(e){ //For each value in visible array    
    var i = flatArr.indexOf(e.toString()); 
    while (i != -1){ //if flatArray has the visible value        
      flatArr.splice(i,1); //splice(delete) it
      i = flatArr.indexOf(e.toString());
    }
  });
  return flatArr;
}

Another method is to use filter(). This will also remove duplicates:

function getHiddenValueArray(colValueArr,visibleValueArr){
  var flatUniqArr = colValueArr.map(function(e){return e[0];})
  .filter(function(e,i,a){return (a.indexOf(e.toString())==i && visibleValueArr.indexOf(e.toString()) ==-1); })
  return flatUniqArr;
}
