google-apps-script - 创建新文件夹并复制谷歌表格，使用新名称到新文件夹

Question

我正在尝试根据电子表格中的数据在 Google 云端硬盘中自动创建新文件夹。电子表格从表单获取信息。我已经弄清楚如何使用脚本创建新文件夹，但有以下问题:

1. 如何避免每次运行脚本时创建重复的文件夹？例如，如果已创建名为“1808”的文件夹，我不希望脚本创建“1808(1)”

2. 我想从其他位置复制电子表格并插入到我正在创建的新文件夹中。新文件名将使用同一电子表格中的信息创建。

   function makeFolders(){
   
   //Get array of folder names (fixed & variable)
   var ss = SpreadsheetApp.getActiveSpreadsheet();
   var sheet = ss.getActiveSheet();
   var bottomRow = sheet.getMaxRows()-2;
   var folderNames = sheet.getRange(2, 12, bottomRow, 1).getValues();
   
   //If fixed name cell is blank it throws up an alert and stops      
   if (folderNames === "") {
       SpreadsheetApp.getUi().alert('Cell A3 is blank.');
   }
   
   //If folder ID cell is blank it throws up an alert and stops
   var folderUrl = sheet.getRange(3,14).getValue();  
   if (folderUrl === "") {
       SpreadsheetApp.getUi().alert('Cell C3 is blank.');
   }      
   
   //If fixed name cell and file URL aren't empty, run the program  
   if (folderNames !== "" && folderUrl !== "") {    
       //Get ID from folder URL
       var folderId = folderUrl.match(/[-\w]{25,}/);    
       //Get master folder 
       var getRootFolderId = DriveApp.getFolderById(folderId);
   
       //Copy master n times and rename each copy with the new name
       //stops when it comes to a blank cell 
       for (n=0;n<bottomRow;n++){
             if(folderNames[n] == ""){break;}
   
             var newFolder = getRootFolderId.createFolder(folderNames[n]);
       }
       ss.toast("Your folders have been made! :)","Finished",3);
   }
   }**strong text**

How do I avoid creating duplicate folders each time the script is run? For example if a folder named '1808' has already been created, I don't want the script to create '1808(1)'

您可以获得所有文件夹名称的列表，并循环遍历它们以检查是否有任何与新文件夹名称匹配!像这样的东西:

function MakeNewFolders(rootFolderID, folderNames)
    // Get master folder 
    var rootFolder = DriveApp get folder (rootFolderID)
    var subfolders = rootFolder.getFolders()
    var alreadyExists = false;
    var newFolder;

    // Check if any subfolder already exists
    //   loop for folders first, to minimize GAS function calls
     while (subfolders.hasNext()) {
        var subfolderName = subfolders.next().getName();
        loop (each folder in folderNames) {
            if (subfolderName == newFolderName)
                alreadyExists = true;
        }
        if (!alreadyExists)
            newFolder = rootFolder.createFolder(newFolderName)
     }

如果您需要循环遍历大量文件夹(超过 60 个左右)，here is a code snippet you might find handy 。基本上，the original Google example当您可以仅使用 try-catch block 并忽略“您已到达末尾!”时，通过检查 folder.hasNext() 来获取子文件夹列表的运行速度会慢两倍。它抛出异常。应该将执行时间减少一半! :)

I want to copy a spreadsheet from another location and insert in the new folders that I am creating. The new file name is to be created with information from the same spreadsheet.

尝试这样的事情!

function CopyFile(originalFileID, destinationFolderID) {
  var destinationFolder = DriveApp.getFolderById(destinationFolderID) ;
  var fileToCopy = DriveApp.getFileById(originalFileID)
  var copiedFile = fileToCopy.makeCopy(<new name>, destinationFolder)
  fileToCopy.setTrashed(true); // alternatively, you can use 
    // Drive.Files.remove(originalFileID);  
}

希望这有帮助!自从我使用 GAS 以来已经有一段时间了，希望它能编译:)
