Google Apps 脚本 - 尝试在 Gmail 上按名称查找 Google Sheet

Question

我正在尝试创建一个 sheet，它将像数据库一样工作，用于存储来自 Gmail 的某些数据（我的边栏仅适用于 Gmail）。

但是，在为此创建新的 google sheet 之前，我必须查看 sheet 是否已经存在。如果是，我想将数据保存到现有的 sheet.

我该怎么做？

GetContextualAddOn.gs

var MESSAGE;
//Returns the sidebar with his cards
function getContextualAddOn(event) {
  MESSAGE = getCurrentMessage(event);
  var prefills = [getTitle(MESSAGE),
                  getBody(MESSAGE)];
  var card = createExpensesCard(prefills);

  return [card.build()];
}

//Get the current message opened
function getCurrentMessage(event) {
  var accessToken = event.messageMetadata.accessToken;
  var messageId = event.messageMetadata.messageId;
  GmailApp.setCurrentMessageAccessToken(accessToken);
  return GmailApp.getMessageById(messageId);
}

Answer 1

function  ifExists(name) {
  var ss=SpreadsheetApp.getActive();
  var shts=ss.getSheets();
  for(var i=0;i<shts.length;i++) {
    if(shts[i].getName()==name) {
      return true;
    }
  }
  return false;
}

我会这样做的：

function  ifExists() {
  var ss = SpreadsheetApp.getActive();
  var shts = ss.getSheets();
  for(let sheet of shts) {
    if(sheet.getName() == 'DBQuiteOften') {
      var retorno = {found:true,sheet:sheet};
      return retorno;
    }
  }
  var retorno = {found:false,sheet:''};
  return retorno;
}

那么这个 var exist = ifExists(); 将是：var exist = ifExists().found;

而这个 if(!exist[0]) 将是：if(!exist.found)

Answer 2

我找到了我需要的答案。使用 DriveApp。

function ifExists() {
  var title = "SheetFileName";

  var files = DriveApp.searchFiles('mimeType contains "spreadsheet" and title contains "' + title + '"');

  while (files.hasNext()) {
    var file = files.next();
    var retorno = [true,file];
    return retorno;
  }
  var retorno = [false,];
  return retorno;
}
