// Open a form by ID and log the responses to each question.
const form = FormApp.openById('1234567890abcdefghijklmnopqrstuvwxyz');
const formResponses = form.getResponses();
for (let i = 0; i < formResponses.length; i++) {
const formResponse = formResponses[i];
const itemResponses = formResponse.getItemResponses();
for (let j = 0; j < itemResponses.length; j++) {
const itemResponse = itemResponses[j];
Logger.log(
'Response #%s to the question "%s" was "%s"',
(i + 1).toString(),
itemResponse.getItem().getTitle(),
itemResponse.getResponse(),
);

getResponse()
取得受訪者提交的答案。對於大多數類型的題目項目,這會傳回 String
。
對於 CheckboxItem
問題,這會傳回包含回應者選擇的 String[]
陣列。陣列中字串的順序可能不同。
對於 GridItem
問題,這會傳回 String[]
陣列,其中索引 n
的答案會對應至格狀檢視畫面中第 n + 1
列的問題。如果受訪者未回答格狀檢視中的某個問題,系統會將該答案傳回為 ''
。
對於 CheckboxGridItem
問題,這會傳回 String[][]
陣列,其中資料列索引 n
的答案會對應至核取方塊格線中資料列 n + 1
的問題。如果受訪者未回答格狀檢視中的某個問題,系統會將該答案傳回為 ''
。
