删除或更新一定范围的单元格时，Google表格时间戳记脚本未更新

Question

This is my first time posting so I hope I've done everything right :)

I've implemented a script in a google sheets that creates a timestamp in column B, when a cell is edited on that row.

It works perfectly, except:

1. when I select a range of cells and press "delete", only one of the timestamps updates (the timestamp of the active cell), even though I've modified multiple cells
2. If I drag downwards to auto-fill values from one cell down into multiple cells (eg, if I drag from A1 down to A5, to fill A2-A5 with the value that was in A1), then only the first timestamp (eg, A2) updates, and the rest stay as they were.

Any ideas how to fix these issues?

Here's my code

 function onEdit(e) { var s = SpreadsheetApp.getActiveSheet(); var r = s.getActiveCell(); if( r.getColumn() != 2 && e.source.getActiveSheet().getName() === "MySheet") { //checks the column & checks the sheet is the correct one var row = r.getRow(); var time = new Date(); time = Utilities.formatDate(time, "GMT+10:00", "dd/MM/yyyy HH:mm:ss"); SpreadsheetApp.getActiveSheet().getRange('B' + row.toString()).setValue(time); }; }; 

And here's an example spreadsheet that has the code:

It's generally good practice to use the event object for everything related to that action.

Handling multiple rows can be handled by using the range of the event a bit further to get the extent of it.

function onEdit(e) {
  var r = e.range;

  if(r.getColumn() !== 2 && r.getSheet().getName() === "MySheet") {
    var row = r.getRow();
    var lastRow = r.getLastRow();
    var time = new Date();
    time = Utilities.formatDate(time, "GMT+10:00", "dd/MM/yyyy HH:mm:ss");

    r.getSheet().getRange(row, 2, lastRow - row + 1, 1).setValue(time);
  };
 };
