Google Sheet Apps 脚本超出最长时间

Question

I have a dynamic dropdown apps script running on only 1 cell and there are some other formulas running in my sheet. Until 2 days before i could run the script onEdit but i cant seem to do so now. When checked inside apps script execution page it shows "Exceeded maximum execution time". What can i do to resolve this?

var mainWsName = "Print Sheet";
var mainDataName = "Orders";
var FirstLevelColumn = 1;
var SecondLevelColumn = 2;
var ThirdLevelColumn = 3;
var ws = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(mainWsName);
var wsJO = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(mainDataName);
var JO = wsJO.getRange(2,1,wsJO.getLastRow()-1,2).getValues();


function onEdit(e){
  var activeCell = e.range;
  var val = activeCell.getValue();
  var r = activeCell.getRow();
  var c = activeCell.getColumn();
  var wsName = activeCell.getSheet().getName();
  if(wsName === mainWsName && c === FirstLevelColumn && r > 1){
     applyFirstLevelValidation(val,r); 
  }else if(wsName === mainWsName && c=== SecondLevelColumn && r > 1){
    applysecondLevelValidation(val,r);
  }
} //end onEdit

function applyFirstLevelValidation(val,r){ 

   if(val === ""){
    ws.getRange(r,SecondLevelColumn).clearContent();
    ws.getRange(r,SecondLevelColumn).clearDataValidations();
    } else {
      ws.getRange(r,SecondLevelColumn).clearContent();
      var filteredJO = JO.filter(function(o){return o[0] === val });
      var listToApply = filteredJO.map(function(o){return o[1]});
      var cell = ws.getRange(r,SecondLevelColumn);
      applyValidationToCell(listToApply,cell);
    }
}


function applyValidationToCell(list,cell){
  
             
  var rule=SpreadsheetApp.newDataValidation().requireValueInList(list).setAllowInvalid(false).build();        
  
   cell.setDataValidation(rule);

}

Tried executing app script to get dynamic dropdown based on my selection.

The code you quote is suboptimal, but chances are that the bad performance you mention is caused by the spreadsheet rather than the script. To improve spreadsheet performance, see these optimization tips .
