How do I automatically set a Google Sheets cell to the current date on editing its row?

问题

I have a Google Spreadsheet that I want to automatically set the value of a "Date" cell whenever I edit a row where the date has not already been set. As far as I know the Google Sheets API and how GoogleScript works, I figure this should work, but it never even sets the debug cell! What am I doing wrong here?

/**
 * Automatically puts the current date in the first column of the edited row
 */
function onEdit(event){
  var sheet = event.source.getActiveSheet();
  var debugCell = sheet.getCell(10,10);
  debugCell.setValue("DEBUG CELL"); // if anything works, this should show up... but it doesn't :C

  var editedCell = sheet.getActiveCell();
  var dateCol = 0;
  var dateCell = sheet.getCell(editedCell.getRow(), dateCol);

  debugCell.setValue(editedCell.getColumn());

  if(!dateCell.getValue() && editedCell.getColumn() != dateCol){   
    dateCell.setValue(new Date());
  }
}

I suppose you did not set the triggers. In the Script editor, go to Resources -> Current project's triggers Select your function name (in this case onEdit) and set the Event as From Spreadsheet -> onEdit

Save it and you are done.

Okay there is problem in your code too. I missed that earlier.

getCell is a function of class range and NOT class sheet. You should use getRange instead. Here is a code that should work. You can edit it as per your requirements.

function onEdit(event){
  var sheet = event.source.getActiveSheet();
  var debugCell = sheet.getRange(10,10);
  debugCell.setValue("DEBUG CELL"); // if anything works, this should show up... but it doesn't :C

  var editedCell = sheet.getActiveCell();
  var dateCol = 1;
  var dateCell = sheet.getRange(editedCell.getRow(), dateCol);

  debugCell.setValue(editedCell.getColumn());

  if(!dateCell.getValue() && editedCell.getColumn() != dateCol){   
    dateCell.setValue(new Date());
  }
}
