我正在努力弄清楚為什么我在這里使用的 Javascript includes() 函數(shù)不匹配并返回true. 該代碼在 Google 表格上的 Google 腳本中用于填充一些單元格值。這是完整腳本中的相關(guān)代碼：const currentYear = getCurrentYear();//Get current year from active sheet namefunction getCurrentYear(){  year = sheetName.slice(-7, -2);  return year; //returns "2020"}//Return Current Control File IDfunction getCurrentControlFileId(){    const controlFolder = DriveApp.getFolderById(controlFolderId);  const controlFiles = controlFolder.getFiles();    while (controlFiles.hasNext()){    let controlFile = controlFiles.next();    let currentControlFileName = controlFile.getName(); // Evaluates to "CONTROL 2020"    let searchString = `${currentYear}`; // Evaluates to "2020"    //Have also tried:    //let searchString = currentYear;         if (currentControlFileName.includes(searchString)){      let controlFileId = controlFile.getId();      return controlFileId;    }  }  }controlFile.getName().includes(searchString)false即使controlFile.getName()值為“CONTROL 2020”且searchString值為“2020”，也會返回。兩者都是字符串。if如果我像這樣在語句條件中手動輸入“2020” ：controlFile.getName().includes("2020")它返回 true 并按預(yù)期工作，返回 ID 字符串。我也嘗試過 wrapping currentYearand controlFile.getName()inString()但它仍然返回 false。我真的看不出這里有什么問題，希望得到一些幫助。
