Google Script adding cell name on a formula - google-apps-script

Question

I'm new to google script, and learn a lot by searching through this site, but now I'm trying to figure out how can I add a cell name (A1, A2, .....) to a formula using google script.
Please see my sample here: https://docs.google.com/spreadsheets/d/1mttb7dD4RvfXmNt3xGe7cAR6SAXB7Tom97vNOK-YQB0/edit?usp=sharing
On column C you will see "=A16+1" but it should be like "=A2+1" since I'm on row 2
here is the google script code
function myFunction() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("test1");
var range = sheet.getActiveCell();
var valueToWatch = "y";
var searchRange = sheet.getRange("A1:A" + sheet.getLastRow()); // Modified
// get the values in an array
var values = searchRange.getValues();
// examine the values in the array
var i = [];
for (var y = 0; y < values.length; y++) {
if (values[y][0] == valueToWatch) {
i.push("C" + (y + 1)); // Modified
}
}
//sheet.getRangeList(i).setValue("this is a test");
var data = [];
for (var x = 0; x < values.length; x++) {
data = ['=A' + (x + 1).toString() + '&"1"'];
}
sheet.getRangeList(i).setFormula(data);
}

Answer 1

Upon reviewing your code, it looks like you want to add formula to column C if the same row in column A has y.
Try this code below:
function myFunction() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("test1");
var valueToWatch = "y";
var searchRange = sheet.getRange("A1:A" + sheet.getLastRow()); // Modified
var values = searchRange.getValues();
var i = [];
for (var y = 0; y < values.length; y++) {
if(values[y][0] == valueToWatch){
i.push("C" + (y + 1));
}else{
i.push('');
}
}
var data = [];
for (var x=0; x < i.length; x++){
if(i[x] != ''){
var rowNum = i[x].replace( /^\D+/g, '');
data.push(['=A' + rowNum + '&"1"' ])
}else{
data.push(['']);
}
}
sheet.getRange("C1:C" + sheet.getLastRow()).setFormulas(data);
}
