javascript - ReferenceError: "range"未定义。谷歌脚本

Question

嘿，我正在为 friend 开发一个 Google 脚本程序，供 friend 在即将到来的梦幻棒球赛季开始时使用，但我收到了错误

“ReferenceError:未定义“范围”。”

我查了一下，没有发现任何有帮助的东西。我的大部分编程技能都是自学的，所以它们有点断断续续，有些东西我无法理解，直到我让它工作一次。如果您有解决方案或任何想法出了什么问题，我们将不胜感激，并且对错误的解释会更好!谢谢。另外，我还没有实现除 C 之外的任何情况，因为我仍在测试。

//var rowsToHide = new Array();   possibly more effiecent and easier to just hide directly
var pos = "";
//var dataStartRow = 1;   would like to add a adjustabke data start spot for use through any spreadsheet
var cellID = "A";
var cellInfo = "";
var cellInfoFirstHalf = "";
var cellInfoSecondHalf = "";
var forwardSlashIndex;
var doublePos = 0;      //0 for false, 1 for true
var ss = SpreadsheetApp.getActiveSpreadsheet(); 
var sheet = ss.getSheets()[0];
var activeRange = SpreadsheetApp.getActiveRange();
var activeSheet = activeRange.getSheet();
var formula = activeRange.getFormula();

//sets up menu item to use script
function onOpen() {
  var ui = SpreadsheetApp.getUi();
  ui.createMenu('Hide Menu')
      .addItem('Show Catchers', 'showCatchers')
      .addItem('Show First Base', 'showFirstBase')
      .addItem('Show Second Base', 'showSecondBase')
      .addItem('Show Third Base', 'showThirdBase')
      .addItem('Show Short Stop', 'showShortStop')
      .addItem('Show Outfield', 'showOutfield')
      .addToUi();
}

//checks which cells need to be hidden
function hideData(posCase) {
  switch(posCase) {
    case "C":
      for (var i=3; i <= range.getNumRows(); i++) {
        doublePos = 0;
        cellID = "A" + i;
        cellInfo = sheet.getRange(cellID).getValue();
        forwardSlashIndex = cellInfo.search("/");
        if (forwardSlashIndex != -1) {
          cellInfoFirstHalf = cellInfo.substring(0,forwardSlashIndex);
          cellInfoSecondHalf = cellInfo.substring(forwardSlashIndex + 1);
          doublePos = 1;
        };
        if (doublePos == 0) {
          if (cellInfo != "C") {
            log(i);
            //sheet.hideRows(i, 1);
          };
        } else {
          if (cellInfoFirstHalf == "C" || cellInfoSecondHalf == "C") {
            log(i);
            //sheet.hideRows(i, 1);
          };
        };
      };
      break;
    case "1B":

      
      
      break;
    case "2B":

      
      
      break;
    case "3B":

      
      
      break;
    case "SS":

      
      
      break;
    case "OF":

      
      
      break;
    default:
      window.alert("There was an error, debugging required!");
      break;
  };
};

//multiple functions for the multiple menu buttons
function showCatchers() {
  pos = "C";
  hideData(pos);
};

function showFirstBase() {
  pos = "1B";
};

function showSecondBase() {

function showShortStop() {

function ShowOutfield() {
  pos = "OF";
};

此错误消息意味着您正在尝试访问未声明的变量，即没有 var 的变量陈述。 (它确实应该说“未声明”而不是“未定义”，但这就是 JavaScript 中的方式。)我只看到 range 出现一次。在您的脚本中，并且未声明。这行代码写着 for (var i=3; i <= range.getNumRows(); i++) { .

也许你想写 activeRange.getNumRows() 。或者也许你想写 var range = ... ;在脚本的顶部。目前我能告诉你的就这么多了……希望你能自己解决剩下的问题。
