Excel Javascript API - 在相邻单元格上记录日期

Question

I am new to Excel JavaScript. I'm trying to record the date a cell changed in column 4 and update column 7 with the date & time the change occurred. I'm encountering parameter out of range whit the.getColumn statement. Hope someone gives me some guidance.

function main(workbook: ExcelScript.Workbook) {
 var s= workbook.getActiveWorksheet();
  if(s.getName() =="Records"){
  var r = workbook.getActiveCell();
  if(r.getColumn(4)) {
      var nextCell = r.getOffsetRange(0, 3);
      nextCell.setValue(new Date());
  }
 }
}

This is because getColumn is to get a column contained in the range.

You would need to use range.columnIndex == 4 , please note columnIndex is Zero-indexed.

function main(workbook: ExcelScript.Workbook) {
 var s= workbook.getActiveWorksheet();
  if(s.getName() =="Records"){
  var r = workbook.getActiveCell();
  r.load('columnIndex');
  await context.sync();

  if(r.columnIndex == 4) {
      var nextCell = r.getOffsetRange(0, 3);
      nextCell.setValue(new Date());

  }
