If dynamic values exist somewhere else then format those values - google-apps-script

Question

I am looking to find if non-consecutive dynamic values are found in another sheet B. If so, I want to format those values in Sheet A.
The problem with my code is that it is going through a range while the values I am looking for are not consecutive. So I'm not sure if a for loop is what should be used in this case.
function homeBoxlianTasks() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var todolistsheet = ss.getSheetByName("To-Do List")
var todolistliantaskvalues = todolistsheet.getRange("B6:B").getValues();
var todolistlianbackground = todolistsheet.getRange("B6:B").getBackgrounds()
var homeboxsheet = ss.getSheetByName("HomeBox");
var homeboxtaskvalues = homeboxsheet.getRange("homeboxtodotasks").getValues();
var backgrounds = [];
var fontLines = [];
//for each row that data is present
for(var i = 0; i < homeboxtaskvalues.length; i++) {
var ltValue = todolistliantaskvalues[i][0];
var hValue = homeboxtaskvalues[i][0];
var lbValue = todolistlianbackground[i][0];
if((hValue === ltValue) && lbValue === '#d9ead3') {
backgrounds.push(["#d9ead3"]);
fontLines.push(['line-through']);
}
else {
backgrounds.push([null]);
fontLines.push([null]);
}
}
homeboxsheet.getRange("homeboxtodotask1").setFontLines(fontLines).setBackgrounds(backgrounds);
}

Answer 1

Based on your reply:
I have 2 employees with a to-do list one under the other. Every time a task is done, there is a checkbox which will highlight and scratch the task in SheetA. I want that task to be also highlighted and scratched in Sheet B.
Try using an onEdit() trigger. Try the following code:
function onEdit(e) {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getActiveSheet();
var summarySheet = ss.getSheetByName("Sheet1");
var range = e.range
var row = range.getRow()
var col = range.getColumn()
if (sheet.getName() == "Sheet0" && col == 1) {
var taskCell = sheet.getRange(row, col + 1)
var taskName = taskCell.getValue();
if (range.isChecked()) {
taskCell.setFontLine("line-through");
} else {
taskCell.setFontLine(null);
}
var checker = range.isChecked();
while (checker != null) {
row = row - 1
checker = sheet.getRange(row, col).isChecked();
}
var name = sheet.getRange(row - 1, col + 1).getValue();
var sumSheetRow = summarySheet.createTextFinder(name).findNext().getRow();
var sumSheetLastCol = summarySheet.getLastColumn();
var sumSheetCol = summarySheet.getRange(sumSheetRow,2,1,sumSheetLastCol-1).createTextFinder(taskName).findNext().getColumn();
var sumSheetTaskCell = summarySheet.getRange(sumSheetRow, sumSheetCol);
if (range.isChecked()) {
sumSheetTaskCell.setFontLine("line-through");
} else {
sumSheetTaskCell.setFontLine(null);
}
}
}
Result:
This also removes the strikethrough if unchecked:
Hope this helps!
EDIT:
Try:
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sh0 = ss.getSheetByName("Sheet0");
var sh1 = ss.getSheetByName("Sheet1");
function test() {
loopThroughTasks("Gaelle")
loopThroughTasks("Lian")
}
function loopThroughTasks(name) {
//ADD THE NAME AND RANGE IF NEEDED
if (name == "Gaelle") {
//Fixed Range and Start Row for Gaelle
var tasks = sh0.getRange("A6:B21").getValues();
var row = 6
} else if (name == "Lian") {
//Fixed Range and Start Row for Lian
var tasks = sh0.getRange("A24:B33").getValues();
var row = 24
}
for (var i = 0; i < tasks.length; i++) {
if (tasks[i][0] === 'Y') {
var sh1Cell = sh1.createTextFinder(tasks[i][1]).findNext().getCell(1, 1).getA1Notation()
sh0.getRange(row, 2).setBackground('#d9ead3')
.setFontLine('line-through');
sh1.getRange(sh1Cell).setBackground('#d9ead3')
.setFontLine('line-through');
} else if (tasks[i][0] === 'N' && tasks[i][1] != "") {
var sh1Cell = sh1.createTextFinder(tasks[i][1]).findNext().getCell(1, 1).getA1Notation()
sh0.getRange(row, 2).setBackground('#fff2cc')
.setFontLine(null);
sh1.getRange(sh1Cell).setBackground('#fff2cc')
.setFontLine(null);
};
row++
}
}

Answer 2

This is essentially your code:
function myfunk() {
var ss = SpreadsheetApp.getActive();
var sh1 = ss.getSheetByName("Sheet0")
var vs1 = sh1.getRange("B6:B" + sh1.getLastRow()).getValues();
var bg1 = sh1.getRange("B6:B" + sh1.getLastRow()).getBackgrounds()
var sh2 = ss.getSheetByName("Sheet1");
var vs2 = sh2.getRange("B6:B" + sh2.getLastRow()).getValues();
var backgrounds = [];
var fontLines = [];
for (var i = 0; i < vs2.length; i++) {
if ((vs2[i][0] === vs1[i][0]) && bg1[i][0] === '#ffffff') {
backgrounds.push(["#ffff00"]);
fontLines.push(['line-through']);
} else {
backgrounds.push([null]);
fontLines.push([null]);
}
}
sh2.getRange(6,2,fontLines.length,1).setFontLines(fontLines).setBackgrounds(backgrounds);
sh1.getRange(6,2,fontLines.length,1).setFontLines(fontLines).setBackgrounds(backgrounds);
}
Both sheet contain the same data

Image of highlight output:
Non consecutive values can be found it's simply a line by line search. If it finds to elements in column B that are identical it highlight and strikes through.
