Use range instead of array of indivdual cells - google-apps-script

Question

I have this code which works for cells A2-A4:
//The function onEdit ensures that checkboxes deleted (by mistake) in the sheet are immediately re-created.
function onEdit(e) {
var spreadsheet = SpreadsheetApp.getActive();
if(spreadsheet.getSheetName()=='MySheet') { //to avoid executing for another sheet
var checkboxCells = [
'A2','A3','A4'];
var range = e.range;
var value = range.getValue();
var a1Notation = range.getA1Notation();
if (checkboxCells.indexOf(a1Notation) != -1 && value != 'TRUE' && value != 'FALSE') {
range.insertCheckboxes();
}
}
};
However I need to work with a 1D range (since there are many cells) and hence I am trying to use this:
//The function onEdit ensures that checkboxes deleted (by mistake) in the sheet are immediately re-created.
function onEdit(e) {
var spreadsheet = SpreadsheetApp.getActive();
if(spreadsheet.getSheetName()=='MySheet') { //to avoid executing for another sheet
var checkboxCells = spreadsheet.getSheetByName('MySheet')
.getRange('MyRange').getA1Notation();
var range = e.range;
var value = range.getValue();
var a1Notation = range.getA1Notation();
if (checkboxCells.indexOf(a1Notation) != -1 && value != 'TRUE' && value != 'FALSE') {
range.insertCheckboxes();
}
}
};
I think this second version should work, but it does not.
Why does it not work?

Modification points:
In order to check whether the edited cell is included in the specific range you expect, the following sample script can be used. (var { range } = e;)
var checkboxCells = sheet.getRange('MyRange');
var startRow = checkboxCells.getRow();
var endRow = startRow + checkboxCells.getNumRows() - 1;
var startCol = checkboxCells.getColumn();
var endCol = startCol + checkboxCells.getNumColumns() - 1;
var check = range.rowStart >= startRow && range.rowEnd <= endRow && range.columnStart >= startCol && range.columnEnd <= endCol;
In order to check whether the edited cell is the checkbox, isChecked() can be used. In this case, when the cell is the checkbox, true or false are returned. When the cell is not the checkbox, null is returned. I thought that this might be able to be used.
When these points are reflected in your script, how about the following modification?
Modified script:
Please set your sheet name and your range.
function onEdit(e) {
var { range } = e;
var sheet = range.getSheet();
if (sheet.getSheetName() == 'MySheet') {
var checkboxCells = sheet.getRange('MyRange');
var startRow = checkboxCells.getRow();
var endRow = startRow + checkboxCells.getNumRows() - 1;
var startCol = checkboxCells.getColumn();
var endCol = startCol + checkboxCells.getNumColumns() - 1;
var check = range.rowStart >= startRow && range.rowEnd <= endRow && range.columnStart >= startCol && range.columnEnd <= endCol;
if (check && range.isChecked() === null) {
range.insertCheckboxes();
}
}
}
In this modified script, when a cell is edited, when the edited cell is included in MyRange, it checks whether the edited cell is a checkbox when the edited cell is not a checkbox, the checkboxes are inserted into the edited cell.

isChecked()
