TimeStamp Updates to Adjacent Columns - google-apps-script

Question

I've was wondering if what to do is possible and how to go about it. This is For Google Sheets. Here is the script I'm using (Found this script and edited it for my use):
function onEdit(e) {
var s = e.source.getActiveSheet().getName();
var cols = [5];
if (s !== 'Michele' && s !== 'Janet' && s !== 'Stephanie' || cols.indexOf(e.range.columnStart) ==-1 || !e.value) return;
e.range.offset(0,1).setValue(Utilities.formatDate(new Date(), "CST", "MM/dd/yyyy HH:mm:ss"));
}
Column 5 (E) has the option to choose different statuses. So far, I have it putting the TimeStamp of Column 5's change in its adjacent column, 6 (F). What I'm trying to figure out is if the status is changed again (Pending -> Confirmed-> Installed-> ect) , instead of updating Column 6, which would already be TimeStamped, it will instead move on to Column 7, then 8, then 9, ect.
Let me know if more detail is needed.
Thanks a Bunch!

Answer 1

I've tested this code and it works. It finds the number of cells to the right of column E that already have values in them, and then calculates what the next empty column is, and writes the new date to the next empty column.
function onEdit(e) {
var sh = e.source.getActiveSheet();
var s = sh.getName();
var lastCol = sh.getLastColumn();
var cols = [5];
var startCol = SpreadsheetApp.getActiveSpreadsheet().getRangeByName('ColumnE').getColumn();
//In the spreadsheet, name a range that is in the column you want to start at
if (s !== 'Michele' && s !== 'Janet' && s !== 'Stephanie' || cols.indexOf(e.range.columnStart) ==-1 || !e.value) return;
var rowEdited = e.range.getRow(); //Get the row that was edited
//Start in row edited and column 6, get 1 row and X columns
var datesInCells = sh.getRange(rowEdited,startCol,1,lastCol - 5).getValues();
Logger.log('datesInCells: ' + datesInCells);
Logger.log('datesInCells.length: ' + datesInCells[0].length);
var numberOfDates = 0;
for (var i=0;i<datesInCells[0].length;i+=1) {
if (datesInCells[0][i] !== "") {
numberOfDates +=1;
};
};
Logger.log('numberOfDates: ' + numberOfDates);
var colToWriteTo = startCol + numberOfDates;
var newDate = Utilities.formatDate(new Date(), "CST", "MM/dd/yyyy HH:mm:ss");
//var theStatus = sh.getRange(rowEdited, 5).getValue();
var theStatus = e.value;
var bothStatusAndDate = newDate + " : " + theStatus;
sh.getRange(rowEdited,colToWriteTo).setValue(bothStatusAndDate);
};
Version two:
function onEdit(e) {
var sh = e.source.getActiveSheet();
var s = sh.getName();
var lastCol = sh.getLastColumn();
var cols = [5];
if (s !== 'Michele' && s !== 'Janet' && s !== 'Stephanie' || cols.indexOf(e.range.columnStart) ==-1 || !e.value) return;
var rowEdited = e.range.getRow(); //Get the row that was edited
//Start in row edited and column 6, get 1 row and X columns
var datesInCells = sh.getRange(rowEdited,6,1,lastCol - 5).getValues();
Logger.log('datesInCells: ' + datesInCells);
Logger.log('datesInCells.length: ' + datesInCells[0].length);
var numberOfDates = 0;
for (var i=0;i<datesInCells[0].length;i+=1) {
if (datesInCells[0][i] !== "") {
numberOfDates +=1;
};
};
Logger.log('numberOfDates: ' + numberOfDates);
var newDate = Utilities.formatDate(new Date(), "CST", "MM/dd/yyyy HH:mm:ss");
if (numberOfDates > 4) {
var existingValues = sh.getRange(rowEdited,7,1,4).getValues();
sh.getRange(rowEdited,6,1,4).setValues(existingValues);
sh.getRange(rowEdited,10).setValue(newDate);
return;
};
var colToWriteTo = 6 + numberOfDates;
sh.getRange(rowEdited,colToWriteTo).setValue(newDate);
};
