隐藏/取消隐藏命名范围：改进脚本处理时间？

Question

以下是我用于自动隐藏/取消隐藏Google表格中行组的脚本。

Col B包含下拉菜单，允许用户根据named ranges切换隐藏或取消隐藏行。但是，脚本有点滞后。这是sample spreadsheet，您可以自己查看。

我还没有找到比在Google Apps脚本中创建四个不同阵列更有效的方法......但是对于如何加快这个脚本的任何建议都将非常感激！

（注意：该脚本使用＆＃34;来自电子表格＆＃34;以及＆＃34; On edit＆＃34;触发器。）

function hideRows() {
   var ss = SpreadsheetApp.getActive();
   var sheet = ss.getSheetByName("Sheet");

  //create array of spreadsheet's named ranges
   var namedRanges = ss.getNamedRanges();
   var named = [];
   for (var i = 0; i < namedRanges.length; i++) {
   named.push(namedRanges[i].getName()); 
   }
   var arrName = named.sort();

  //create array of named range values  
   var value = [];
   for (var i = 0; i < arrName.length; i++) {
   value.push(ss.getRangeByName(arrName[i]).getValue()); 
   }

  //create array of named range row indexes  
   var index = [];
   for (var i = 0; i < arrName.length; i++) {
   index.push(ss.getRangeByName(arrName[i]).getRowIndex()); 
   }

  //create array of named range row numbers  
   var rows = [];
   for (var i = 0; i < arrName.length; i++) {
   rows.push(ss.getRangeByName(arrName[i]).getNumRows()); 
   }

    for (var i = 0; i < arrName.length; i++) {
  //If a value in value is equal to "Collapsed" then hide the corresponding named range
      if (value[i] == "Collapsed") {
    sheet.hideRows(index[i+1],rows[i+1]);
      }
  //If a value in value is equal to "Expanded" then show the corresponding named range
  else if (value[i] == "Expanded") {
    sheet.showRows(index[i+1],rows[i+1]);
  }
    }
}

我没有测试过这个。我重写了代码，并将三个循环合并为一个循环。可以更多地合并代码，具体取决于您是否需要进一步将数据用于其他内容。例如，您正在对范围名称进行排序。如果不是真的需要按顺序排列它们，那么代码可以进一步合并。

function HideRows() {
  var arrName,i,index,L,named,namedRanges,
      rngByName,rngNumRows,rngRowIndex,rngVal,rows,
      sheet,ss,thisRng,thisRngName,value;

  ss = SpreadsheetApp.getActive();
  sheet = ss.getSheetByName("Sheet");

  named = [];
  value = [];
  index = [];
  rows = [];

  //create array of spreadsheet's named ranges
  namedRanges = ss.getNamedRanges();

  L = namedRanges.length;

  for (i = 0; i < L; i++) {
    named.push(namedRanges[i].getName()); 
  }

  arrName = named.sort();
  Logger.log(arrName);

  //create array of named range values  

  L = named.length;

  for (i = 0; i < L; i++) {
    thisRngName = arrName[i];
    thisRng = ss.getRangeByName(thisRngName);

    rngVal = thisRng.getValue();
    rngRowIndex = thisRng.getRowIndex();
    rngNumRows = thisRng.getNumRows();

    value.push(rngVal);
    index.push(rngRowIndex);//create array of named range row indexes  
    rows.push(rngNumRows);//create array of named range row numbers

    //If a value in arrValue is equal to "Collapsed" then hide the corresponding named range
    if (rngVal == "Collapsed") {
      sheet.hideRows(index[i+1],rows [i+1]);
    }
    //If a value in arrValue is equal to "Expanded" then show the corresponding named range
    else if (rngVal == "Expanded") {
      sheet.showRows(index[i+1],rows [i+1]);
    }
  }
}
