有没有办法阻止事件在谷歌应用脚​​本中完成？ (即) e.preventDefault()

Question

我目前正在将用户通过 google 表单输入的日期与今天的日期进行比较，如果日期尚未出现，我想停止将表单数据插入到 google 响应电子表格中。我已经用谷歌搜索了这个，但找不到类似于具有 e.preventDefault() 的 DOM 的东西。这是我的代码在谷歌脚本编辑器中的样子：

//first, verify the date of the submission is not before the date of the game (has not happened yet)
var todayDate = new Date();
var gameDate = new Date(ogkGameDate);
if (gameDate < todayDate)
{
  //send an email to admin and user that submission was rejected because the game date is in the future.
var subject = "WFRA Online Game Keeping Submission";

var message = "Hello! Thank you for submitting to the online game keeping system. \n";
message += "\n Unfortunately, the submission was rejected because this game has not yet occurred:";

message +="\n Game Keeper: " + ogkGameKeeper;
message +="\n Game Date: " + gameDate;
message +="\n Submission Date: " + todayDate;

//message += "\n Administrators can view the submission sheet at " + ogkURL + " \n";
message += "\n Please reply to this email if you experience technical issues. \n";


// Send yourself an email with a link to the document.
GmailApp.sendEmail("wfringette@gmail.com", subject, message,{bcc: "thetroutlakemonster@gmail.com", replyTo: "webmaster@westferrisringette.ca"});

//reject the submission to the sheet
    //HERE IS WHERE I WOULD LIKE TO CANCEL THE EVENT TO AVOID DATA INPUT TO THE SPREADSHEET

//exit the code

return;  }

提前感谢您的任何建议！

来自 OP 的评论

我的代码是在我的谷歌表单的 onFormSubmit 中触发的，我的目标是防止电子表格的填充。非常感谢

如果您将表单设置为将表单响应发送到电子表格，则无法阻止填充电子表格，但如果使用表单提交触发器来填充电子表格，则可以。

这样做的方法是在填充电子表格之前设置适当的条件。

顺便说一句，无法将e.preventDefault() 之类的内容添加到 Google 表单，因为无法编辑表单 HTML 或添加自定义 JavaScript。

问题中包含的代码包含比较两个 Dates 对象的条件，但无法直接比较它们。

代替

if (gameDate < todayDate)

使用

if (gameDate.getTime() < todayDate.getTime())

示例如何使用所需数据填充 onFormSubmit 您自己的电子表格

如果您的脚本绑定到您的表单，请执行以下操作：

• 创建您自己的目标电子表格
• 修改您的 if 条件以按照 Ruben 的解释正确比较日期
• 重要提示：如果您想发送电子邮件并避免将来提交游戏日期的表单，正确的查询应该是 if (gameDate.getTime() > todayDate.getTime())
• 添加else 语句以实现如果游戏日期已经发生，则应将表单数据提交到您的自定义电子表格中

示例

function bindMeOnFormSubmitTrigger(e){
  //please define
  var ogkGameKeeper="";
  //sample date
  var ogkGameDate = "2020-09-12";
  var todayDate = new Date();
  var gameDate = new Date(ogkGameDate);
  if (gameDate.getTime() > todayDate.getTime())  {
    //send an email to admin and user that submission was rejected because the game date is in the future.
    var subject = "WFRA Online Game Keeping Submission";
    
    var message = "Hello! Thank you for submitting to the online game keeping system. \n";
    message += "\n Unfortunately, the submission was rejected because this game has not yet occurred:";
    
    message +="\n Game Keeper: " + ogkGameKeeper;
    message +="\n Game Date: " + gameDate;
    message +="\n Submission Date: " + todayDate;
    
    //message += "\n Administrators can view the submission sheet at " + ogkURL + " \n";
    message += "\n Please reply to this email if you experience technical issues. \n";
    
    Logger.log("send email");  
    // Send yourself an email with a link to the document.
    GmailApp.sendEmail("wfringette@gmail.com", subject, message,{bcc: "thetroutlakemonster@gmail.com", replyTo: "webmaster@westferrisringette.ca"});
  } else{
    //paste form data into your own spreadsheet
    var formResponse = e.response;
    var rowData = [];
    var timeStamp = formResponse.getTimestamp();
    rowData.push(timeStamp);
    var itemResponses = formResponse.getItemResponses();
    for (var j = 0; j < itemResponses.length; j++) {
      var itemResponse = itemResponses[j];
      rowData.push(itemResponse);
    }
    //append the form submit data to your own custom sheet
    var mySheet = SpreadsheetApp.openById("PASTE HERE THE ID OF YOUR CUSTOME SPREADSHEET").getSheetByName("PASTE HERE THE NAME OF THE SHEET").appendRow(rowData);
  }
}
