显示Google站点上所有Google Drive文件的列表

每次你 for 循环迭代,它将覆盖前面的内容。

var Output3 = folder.id;

您需要使用以下内容:

var Output3 = "";//define this outside the `for` loop
Output3 = Output3 + folder.id;

下面是对完整代码的重新编写:

function doGet() {
  var query = 'fullText contains "Printers"' ;
  var folders, folder, pageToken, foldersLngth = 0, theItems, output="";

  do {
    folders = Drive.Files.list({
    q: query,
    maxResults: 100,
    pageToken: pageToken
  });

  foldersLngth = folders.items.length;
  theItems = folders.items;

  if (theItems && foldersLngth > 0) {

    for (var i=0; i < foldersLngth; i++) {
      folder = folders.items[i];
      Logger.log('%s (ID: %s)', folder.title, folder.id);
      output = output + folder.title + ", " + folder.id;
    };
  };

  //var Output3 = folder.id; 
  //HtmlService.createHtmlOutput(Output3);
  pageToken = folders.nextPageToken;
  } while (pageToken);

  return HtmlService.createHtmlOutput(output);
};
