Generate a marksheet with some conditions

Question

I'm creating a mark-sheet for my PHP project where I have used JS to determine whether a student is 'pass' or 'fail'.

It checks the sum of 'pass' marks and the obtained marks. If a student gets 0 in one subject but the total is more than the required pass marks then it shows PASS in the result field which I don't want. I want JS to check if it's 0 in any subject and show fail.

Any help is much appreciated. I'm very new to JS. Please guide me.

$(function() {
  var TotalValue = 0;
  $("tr #data").each(function(index, value) {
    currentRow = parseFloat($(this).text());
    TotalValue += currentRow
  });

  document.getElementById('fulltotal').innerHTML = TotalValue;
  var TotalValue1 = 0;
  
  $("tr #data1").each(function(index, value) {
    currentRow = parseFloat($(this).text());
    TotalValue1 += currentRow
  });

  document.getElementById('passtotal').innerHTML = TotalValue1;
  var TotalValue2 = 0;
  $("tr #data2").each(function(index, value) {
    currentRow = parseFloat($(this).text());
    TotalValue2 += currentRow
  });

  document.getElementById('obtotal').innerHTML = TotalValue2;
});

var ptotal = $("#passtotal").val();
var ototal = $("#obtotal").val();
if (ptotal > ototal) {
  document.getElementById('results').innerHTML = "FAIL";
} else {
  document.getElementById('results').innerHTML = "PASS";
}

Here you go, consolidated a bit and normalized to all be jQuery. You seem to be familiar with most of this, but instead of parseFloat, I used the shorthand + which converts the string into a number (float or integer). Also code like this +$(this).find('td').eq(4).text() means find the td with index 3 under me, get its text value and convert into a number. Additionally, in your pass/fail if statement at the end, you were comparing strings, not numbers, so I updated that as well.

$(function() {
  let maxMarks = 0, passMarks = 0, marksAwarded = 0, hasFail = false;
  $("tr").each(function() {
    $(this).find('td').each(function(index) {
      let val = +$(this).text().trim();
      if (index === 2) maxMarks += val;
      else if (index === 3) passMarks += val;
      else if (index === 4) marksAwarded += val;
    });
    if (+$(this).find('td').eq(4).text() < +$(this).find('td').eq(3).text()) hasFail = true;
  });
  $('#fulltotal').html(maxMarks);
  $('#passtotal').html(passMarks);
  $('#obtotal').html(marksAwarded);
  if (marksAwarded < passMarks || hasFail) {
    $('#results').html("FAIL");
  } else {
    $('#results').html("PASS");
  }
});
