Question

我正在基于之前列中单元格中的值在列中的每个单元格中设置验证。如果我的脚本按每个单元一个一个地运行（无循环），则按我的意愿工作。通过脚本在单元格中设置验证并查看效果需要一秒钟左右的时间（我的意思是明显的缓慢）。当我将代码放入for循环中时，它没有在某些单元格上完成任务，我认为由于完成在单元格上应用验证设置所需的时间。仅当验证设置在当前单元格中生效后，我如何才能控制for循环才能再次循环？

我正在尝试在每个单元格中添加从属下拉列表。

我采用了/ http://www.chicagocomputerclasses.com/google-sheets-apps-script-dynamic-dependent-dropdown-data-validation-lists/

中的代码

//google scripts for google spreadsheet  

function addDropDown(){
  var tabLists = "Lists";
  var tabValidation = "DATA";
  var ss = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();

  var datass = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(tabLists);
  var datass0 = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(tabValidation);

  function flatten(arrayOfArrays){
    return [].concat.apply([], arrayOfArrays);
  }

  var dists_in_data = datass0.getRange(5, 2,datass0.getLastRow()).getValues(); //Admin1 in data

  var dists_in_list = datass.getRange(2, 9,datass.getLastRow()).getValues(); //Admin1 in Lists

  dists_in_list = flatten(dists_in_list);
  dists_in_data = flatten(dists_in_data);

  for (var i in dists_in_data){
 //i = 0
    var search_key = dists_in_data[i];   

    var distStart = dists_in_list.indexOf(search_key) + 1;

    dists_in_list.reverse();
    var len = dists_in_list.length;
    var distEnd = len - (dists_in_list.indexOf(search_key) + distStart - 1);
    dists_in_list.reverse();

    //preparing validation list for admin2
    if(distStart != 0){

       var validationRange = datass.getRange(distStart + 1, 10, distEnd );
       var validationRule = SpreadsheetApp.newDataValidation().requireValueInRange(validationRange).build();
       datass0.getRange(i + 5, 3).setDataValidation(validationRule);

     } 

  }

}

我希望所有单元格都应设置新的验证规则。

如何控制循环等到每个循环中的任务完成
