Google Sheet 脚本疑难解答：在行中查找第一个空列

Question

我有一个 Google 脚本，可以根据 Google 表格中的数据创建一个 Google 表单。但是，代码没有正确检测每行中的最后一个空单元格。相反，即使它是空白的，它也会写入行中的每个单元格。所以表格总是有十五种可能选择的问题，因为那是工作表的范围。这是一个错误的form 示例。这是editable version of the sheet 的链接。谢谢你。

function onOpen() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var createForm = [ {name: "Create form", functionName: "CreateFormfromSheet"}];
  ss.addMenu("Generate Test", createForm);
}

function CreateFormfromSheet() {
 var ss = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet1');
 var range = ss.getDataRange(); 
 var data = range.getValues();
 var numberRows = range.getNumRows();
 var numberColumns = range.getNumColumns();
 var firstRow = 2;
 var form = FormApp.create(data[0][1]);

 form.setDescription(data[0][4]);

Answer 1

var getSheetRange =         SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Sheet1').getDataRange();

这一行是获取整个工作表的范围，那么你在下一行使用上面的范围：

var numberOfColumnsSheet = getSheetRange.getNumColumns();

将列数设为 19，因为它包括您的第二行。

试试：

var numberOfColumnSheet = someRowRange.getNumColumns();

Answer 2

使用CHOICE 的块，这就是我的处理方式：

else if (questionType=='CHOICE') {
  // we already have data, no need to retrieve it again
  var choicesForQuestion = [];
  for (var j=4; j < numberColumns; j++)
    if (data[i][j] != "") // only push if there's something to push
      choicesForQuestion.push(data[i][j]);
  form.addMultipleChoiceItem()
    .setTitle(data[i][1]) 
    .setHelpText(data[i][2])
    .setChoiceValues(choicesForQuestion)
    .setRequired(true); 
}
