Google Sheets Calendar

Question

I would like some help in pulling certain data from a google form linked to a spreadsheet and set a certain value in the date of a certain employee. For example if he/she marked as Vacation Leave then the letter V will be marked under the Date. I have attached the link to my calendar to give an example, I have tried searching the net and this is my second time posting here.

I started the Code but I am stuck in actually finding the Cell for a certain date and inserting the letter.

function setData(){
  //Spreadsheets
  var ss = SpreadsheetApp;  
  var data = ss.getActiveSpreadsheet().getSheetByName("Data");
  var calendar = ss.getActiveSpreadsheet().getSheetByName("Calendar");

  //Get last row / Individual Cells from Form
  var lRow = data.getLastRow();
  var lRowData = data.getRange(lRow,1,1,17).getValues();
  var approval = data.getRange(lRow,17,1,1).getValue();  
  var leave = data.getRange(lRow,9,1,1).getValue(); 
  var agentName = data.getRange(lRow, 5,1,1).getValue();
  var dateBefore = data.getRange(lRow, 10,1,1).getValue();
  var dateAfter = data.getRange(lRow, 11,1,1).getValue();

  //Calander Variable Arrays
  var allDates = calendar.getRange("LA1:NJ1").getValues();
  var allNames = calendar.getRange("A4:A160").getValues();

  for(var i = 0; i<allNames.length; i++){
    if (approval === "Approved" && allNames[i][0] === agentName){

   //Here I need it to insert the dates under the correct name and date with a value of V   H   S   M   U   T.


    };

  };
};

You are building a spreadsheet-based Leave Calendar based on information from a form response. Based on your existing Calendar, you are having problems identifying the relevant leave dates, and then filling calendar cells to indicate proposed leave.

The problem is there are no fields in rows 1,2 or 3 of Calendar that have the same date format as the Start Date and End Date fields on Form. As a result, there's no easy way to search for a match of the form data fields.

The solution, in my view, is to change the format of the date fields in rows 2 and 3 and enable a search to be match.

Row 2

• the existing format is "d" - day of the month (Numeric)
• change the format to match the Form Start/End dates: "d-MMM-yyyy".
• the font colour for this field can be used to "hide" these dates, and the column width reduced also.

Row 3

• the existing format is "E" - day of the week (Name)
• change the format to combine the existing formats of rows #2 and #3 - "Ed"

Aspects of the script

• the form data is retrieved as getDisplayValues() . The purpose of this is to get the date as a string to facilitate the search.
• Two sets of Calendar data are obtained
  1) the dates row (Row#2)
  2) the names column (Col #1). The Javascript map method is used to convert names from a 2D array to a 1D array. This creates an array that can be easily searched.
• the Javascript indexOf method is used to find the Column match for the start and end dates, and to match the name in the Calendar Column (which yields the Row)
• the script loops through the number of days leave to create a temporary array of "V" values.
• using the row number and the start and end column numbers, a range can be defined on calendar and then updated from the values in the temporary array.

Presumably your function would be triggered by onFormSubmit(e).
