有没有办法阻止事件在Google Apps脚本中完成？ 即e.preventDefault

如何解决有没有办法阻止事件在Google Apps脚本中完成？ 即e.preventDefault

我当前正在将用户通过Google表单输入的日期与今天的日期进行比较，如果日期尚未发生，我想阻止表单数据插入到Google响应电子表格中。我已经用谷歌搜索了一下，但是找不到类似于具有e.preventDefault（）的DOM的东西。这是我的代码在Google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("[e-mail]",subject,message,{bcc: "[e-mail]",replyTo: "[e-mail]"});

//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！

解决方法

根据OP的评论

我的代码在我的Google表单的onFormSubmit中触发，我的目标是防止填充电子表格。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，则无法阻止电子表格的填充，但是可以使用表单提交提交触发器来填充电子表格。

方法是在填充电子表格之前设置适当的条件。

顺便说一句，由于无法编辑HTML表单或添加自定义JavaScript，因此无法向Google表单添加e.preventDefault()之类的东西。

问题中包含的代码包含一个条件，用于比较两个Dates对象，但不能直接比较它们。

代替

if (gameDate < todayDate)

使用

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

示例如何填充onForm使用所需数据提交自己的电子表格

提供脚本绑定到表单的步骤如下：

• 创建自己的目标电子表格
• 按照Ruben的说明修改您的if条件以正确比较日期
• 重要提示：如果您要发送电子邮件并避免以后再提交游戏日期表格，则正确的查询应为 if (gameDate.getTime() > todayDate.getTime())
• 添加else语句，以实现如果游戏日期已经到来，则将表单数据提交到您的自定义电子表格

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("[e-mail]",subject,message,{bcc: "[e-mail]",replyTo: "[e-mail]"});
  } 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);
  }
}
