適用於表單的Google Apps腳本：想要通過電子郵件向用戶發送特定號碼

Question

可以要求用戶在FORM中寫下他們的電子郵件地址，之後他們會收到具有唯一號碼的電子郵件地址？

我找出如何發送自動發送郵件，在這裏提交 - http://www.labnol.org/internet/auto-confirmation-emails/28386/

但不知道如何發送給他唯一的號碼每！

Answer 1

您可以嘗試上面的代碼來檢索窗體響應的唯一ID。但它不是排序數字（1,2，...）。這是由表單生成的唯一隨機數。我的建議並不是嘗試構建從1開始並繼續前進的內容，因爲它是異步的，您沒有安全性來擁有分類的項目列表。詳情請參閱here。

/** 
* for a form with 2 question named "question 1" and "question 2" 
* this function need to be associated directly to the form 
* and it need to be associated to a trigger "on form submit" 
* the "e" given as argument is generated by the form submit trigger 
*/ 
function submitFormFunc(e) { 
    var items = e.response.getItemResponses(); 
    var responses={}; 
    for(var i = 0; i< items.length; i++) { 
    responses[items[i].getItem().getTitle()]=items[i].getResponse(); 
    } 

    var responseTable = []; 
    var responseIndex = ["Timestamp","ID","question 1","question 2"]; 
    responseTable.push(e.response.getTimestamp().toString()); 
    responseTable.push(e.response.getId()); 
    responseTable.push(responses["question 1"]); // my form have 2 questions named "question 1" and "question 2" 
    responseTable.push(responses["question 2"]); 
    responseTable.push(FormApp.getActiveForm().getResponse(e.response.getId()).getEditResponseUrl()); 
    SpreadsheetApp.openById("YOUR_SPREADSHEET_ID").appendRow(responseTable); 
} 

- 編輯 -

，如果你想要的東西更短，您可以使用時間戳：

改變（或增加）responseTable.push(e.response.getTimestamp().toString());爲

responseTable.push(e.response.getTimestamp().getTime().toString()); 

，甚至更短，但效率稍差：

您可以添加一行：

responseTable.push(generateUnique()); 

，並添加功能：

function generateUnique(){ 
    var vals = SpreadsheetApp.openById("YOUR_SPREADSHEET_ID").getRange("A:A").getValues(); 
    var ids=[]; 
    for(var i in vals){ 
    ids.push(vals[0]); 
    } 
    var newId = Math.floor(Math.random()*100); // change 100 for something bigger if needed 
    while(ids.indexOf(newId)>-1){ 
    newId = Math.floor(Math.random()*100); 
    } 
    Logger.log(newId); 
    return(newId); 
}
