在表单脚本中 - 获取 Google 表单值并弹出一个对话框以表单提交者

Question

Google 表单/表格 - 当用户单击表单上的提交时，我想检查其中一个回复是否已经在 Google 表格中。如果是，我想阻止提交表单并弹出一条消息，告诉他们他们的数据已经分配。

我尝试在电子表格级别添加 Google 脚本。但是弹出消息不起作用，因为最终用户正在与之交互的是表单，而不是工作表。

工作表中的代码：

//Add code to form submit on the Add Key form
function onFormSubmit(e) {
  /* a variable name with Camel Case - every new word Capital */

  /* tell it to trigger on form submit */
  var ss = SpreadsheetApp.getActiveSpreadsheet();  /* sheet for data to goto */
  var sheet_SLAAssignedIdsResponses = ss.getSheetByName("SLAAssignedIdsRESPONSES"); 

  /* calls to the spreadsheet takes a lot of time - resource & same with writing to spreadsheet */
  /* better to to NOT go row by row - SLOW!!! */
  /* have it in memory in an array - faster, then modify it and spit it back out */
  /* house it in memory & read/write when have to */
  var lastRow_SLAAssignedIdsResponses = sheet_SLAAssignedIdsResponses.getLastRow(); /* getting the last added row */  

  var StudentAssignmentExistsAlready = "";
  var SLAIdValue = "";
  var SLAIdCount = "";
  var SLAStudentName  = "";

  // Assign formulas to G and H
   // G - Count # of times SLA ID appears assigned.
  var cell = sheet_SLAAssignedIdsResponses.getRange("G" + lastRow_SLAAssignedIdsResponses); 
    //=IF(ISBLANK(A2),"",COUNTIF(D:D,D2:D))
  cell.setFormula('=IF(ISBLANK(A2:A),"",COUNTIF(D:D,D2:D))');

  // H - Full Name
  var cell = sheet_SLAAssignedIdsResponses.getRange("H" + lastRow_SLAAssignedIdsResponses); 
  // IF(ISBLANK(E2:E)=FALSE,TEXT(E2:E,"00"),"")
  //=B2:B&" "&C2:C
  cell.setFormula('=B2:B&" "&C2:C');

  /*********************************************************/
  // Get the incoming SLAIdValue trying to be assigned.
  SLAIdValue = sheet_SLAAssignedIdsResponses.getRange("D" + lastRow_SLAAssignedIdsResponses).getValue(); 
  //SLAIdValue = sheet_SLAAssignedIdsResponses.getRange(lastRow_SLAAssignedIdsResponses, 3).getValue();
  Logger.log("The value of SLA ID " + SLAIdValue);

  // Get the COUNT for SLAId
  //SLAIdCount = sheet_SLAAssignedIdsResponses.getRange(lastRow_SLAAssignedIdsResponses, 6).getValue();
  SLAIdCount = sheet_SLAAssignedIdsResponses.getRange("G" + lastRow_SLAAssignedIdsResponses).getValue(); 
  Logger.log("The value of SLA ID COUNT " + SLAIdCount);

  // Get the current student assigned
  //SLAIdCount = sheet_SLAAssignedIdsResponses.getRange(lastRow_SLAAssignedIdsResponses, 6).getValue();
  SLAStudentName = sheet_SLAAssignedIdsResponses.getRange("H" + lastRow_SLAAssignedIdsResponses).getValue(); 
  Logger.log("The value of SLA Student Name " + SLAStudentName);

  /*********************************************************/
    // 1 - Look to see if the count for the current row is > 1 - If so, this SLA account is already assigned.
    // 2 - Find the SLAId already assigned for this student that is not equal to this one.

   **if (SLAIdCount >= 2 ){    
     Logger.log("Pop up response ");
   //  var ss = SpreadsheetApp.getActiveSpreadsheet();  /* sheet for data to goto */
    // var sheet_SLAAssignedIdsResponses = ss.getSheetByName("SLAAssignedIdsRESPONSES");

     var sh=SpreadsheetApp.getUi();
     var response=sh.alert("Duplicate SLA ID Assignemnt", "Please select a different Google Id for the Non-District Student.", sh.ButtonSet.OK);

     // Proceed with deleting the LastRow, as we cannot allow this entry. 


   }**

  } // OnFormSubmit END

我希望我可以返回一个对话框，让表单提交者知道他们尝试分配的信息已分配给其他人。

现在，我无法让对话框返回。 我需要有关 Google 应用程序表单脚本的帮助。

您确实知道 Google 表单设置有一个内置选项来限制每个用户提交一次。
