你如何遍历一个对象并替换文本

Question

我有一个脚本，它应该从 google 表单提交创建一个 pdf 文件，并将要更改的数据作为对象获取。但是，我正在使用 replaceText 操作对文档进行更改，但出现以下错误。

异常：无效参数：替换 在 Create_PDF(代码:37:8) 在 After_Submit(代码:13:19)

它应该更改生成的 doc 文件中的值，并且当我使用 namedValues 函数时它起作用了。但是，现在我使用的是 range，它似乎不起作用。

function After_Submit(e){
  var range = e.range;
  var row = range.getRow(); //get the row of newly added form data
  var sheet = range.getSheet(); //get the Sheet
  var headers = sheet.getRange(1, 1, 1, 129).getValues().flat(); //get the header names from A-O
  var data = sheet.getRange(row, 1, 1, headers.length).getValues(); //get the values of newly added form data + formulated values
  var values = {}; // create an object 
  for( var i = 0; i < headers.length; i++ ){
    values[headers[i]] = data[0][i]; //add elements to values object and use headers as key
  }

  Logger.log(values);
  const pdfFile = Create_PDF(values);
  sendEmail(e.namedValues['Email Address to Receive File '][0],pdfFile);
}

function sendEmail(email,pdfFile){
  
  GmailApp.sendEmail(email, "Subject", "Files Attached", {
    attachments: [pdfFile], 
    name: "From Email"

  });
 
}
function Create_PDF(values) {
  const PDF_folder = DriveApp.getFolderById("ID_1");
  const TEMP_FOLDER = DriveApp.getFolderById("ID_2");
  const PDF_Template = DriveApp.getFileById('ID_3');
  
  const newTempFile = PDF_Template.makeCopy(TEMP_FOLDER);
  const  OpenDoc = DocumentApp.openById(newTempFile.getId());
  const body = OpenDoc.getBody();
  
  console.log(body);

  body.replaceText("{{Timestamp}}", values['Timestamp'][0]);
  body.replaceText("{{Location}}", values['Location'][0]);

  const pdfFile =  PDF_folder.createFile(BLOBPDF).setName("FLHA");

  return pdfFile;

}

您的问题是如何遍历对象并替换文本

这会从 Sheet0 创建一个对象：

工作表0：

one	pattern
two	this is the pattern
three	pattern pattern
four	nothing
five	nothing

代码：

function replacepattern() {
  const ss = SpreadsheetApp.getActive();
  const sh = ss.getSheetByName('Sheet0');
  const vs = sh.getRange(1,1,sh.getLastRow(), 2).getValues();
  //creating object from spreadsheet
  let obj = {pA:[]};
  vs.forEach(r =>{
    obj[r[0]]=r[1];
    obj.pA.push(r[0]);
  });
  Logger.log(JSON.stringify(obj));
  let oA = obj.pA.map(p => [obj[p].replace(/pattern/g,'replacement')]);//doing the replacement in an object
  sh.getRange(1,sh.getLastColumn() + 1,oA.length, oA[0].length).setValues(oA);//outputting the replaced string in the next column
  Logger.log(JSON.stringify(oA));
}

Sheet0 运行一次后：

one	pattern	replacement
two	this is the pattern	this is the replacement
three	pattern pattern	replacement replacement
four	nothing	nothing
five	nothing	nothing

Answer 2

这和我的回答here有关。

错误码Exception: Invalid argument: replacement at Create_PDF(Code:37:8) at After_Submit(Code:13:19)是由values['Timestamp'][0]的空值引起的。如果您尝试打印 values['Timestamp'] 的数据类型，它将返回一个类型对象，因为该对象没有索引 0 的值，因此它将返回一个空值。

对于字符串类型的条目，如果您将[0] 添加到它，它将仅返回字符串的第一个元素。示例您有 "Test" 字符串，添加 [0] 将返回 "T"

要解决此问题，只需删除所有 body.replaceText(..., values['...'][0]) 条目中的 [0]。

或

通过将代码中的 body.replaceText 条目替换为以下内容，循环遍历 values 对象：

for (const key in values) {
   body.replaceText("{{"+key+"}}", values[key]);
}

使用示例：

表单输入：

输出：
