google-apps-script - 如何在 Google Apps 脚本中创建动态下拉列表

Question

我想使用 Google Apps 脚本动态更改 Google 电子表格的单元格验证功能中候选列表的值。

我未能使用 Google 公式功能在 Google 电子表格中创建动态下拉列表。

Answer 1

您现在可以使用newDataValidation()来构建数据验证规则。

例子：

// Set the data-validation rule for cell A1 to require a value from B1:B10.
var cell = SpreadsheetApp.getActive().getRange('A1');
var range = SpreadsheetApp.getActive().getRange('B1:B10');
var rule = SpreadsheetApp.newDataValidation().requireValueInRange(range)
    .build();
cell.setDataValidation(rule);

时代变了，看这篇博文

我的电子表格示例可以使用一些改进

博客文章提供了一种简单的方法。我的代码启动器是

function loadMenu() {
  var ga = SpreadsheetApp.getActive();

  var firstMenu = 'B3:B4';
  var firstValues = 'E3:F3';
  var staticValue1 = 'E3';
  var staticValue2 = 'F3';

  var secondMenu = 'C';
  var secondMenuRow = 3;
  var secondMenu1 = 'E4:E';
  var secondMenu2 = 'F4:F';

  dynamicDrop(ga, firstMenu, firstValues, staticValue1, staticValue2, secondMenu, secondMenuRow, secondMenu1, secondMenu2);

}


function dynamicDrop(ga, fm, fv, sv1, sv2, sm, smr, sm1, sm2) {

  //first drop choices
  var cells = ga.getRange(fm);
  var range = ga.getRange(fv);
  var rule = SpreadsheetApp.newDataValidation().requireValueInRange(range).build();
  cells.setDataValidation(rule);

  // set as static value
  var staticVar1 = ga.getRange(sv1).getValue();

  // set as static value
  var staticVar2 = ga.getRange(sv2).getValue();

  // set to chosen value of fm
  var chosenVar1 = ga.getRange(fm).getValues();

  for (var row in chosenVar1) {

    for (var col in chosenVar1[row]) {

      if (chosenVar1[row][col] == staticVar1) {

        num = parseInt(row) + smr;
        var cells = ga.getRange(sm+num);
        var range = ga.getRange(sm1);
        var rule = SpreadsheetApp.newDataValidation().requireValueInRange(range).build();
        cells.setDataValidation(rule);

      } else if (chosenVar1[row][col] == staticVar2) {

        num = parseInt(row) + smr;
        var cells = ga.getRange(sm+num);
        //range is Static values
        var range = ga.getRange(sm2);
        var rule = SpreadsheetApp.newDataValidation().requireValueInRange(range).build();
        cells.setDataValidation(rule);

      }
    }
  }
}
