Array displayed inside Html table

by

I got this code for an array an infinite array in javascript and I can add more to it delete from it update elements inside of it.
I need to show that array as a table in html page the design does not matter I can work on that.

I am only allowed to use JavaScript not jQuery, I’m really not sure what to do here.

let students = [];
let x = 0;
document.getElementById("submit").addEventListener("click", (e) => {
  e.preventDefault();
  let nameInputEl = document.getElementById("name");
  let idInputEl = document.getElementById("idNumber");
  let gdpaInputEl = document.getElementById("gdpa");

  // Validation for input
  inputValidation(nameInputEl.value, idInputEl.value, gdpaInputEl.value);

  // insert student
  if (x == 1) {
    insertStudent(nameInputEl.value, idInputEl.value, gdpaInputEl.value);
  }

  // Show success message
});

function inputValidation(name, id, gdpa) {
  // check for the value of each element

  if (name == "") {
    document.getElementById("Error101").style.display = "block";
  } else if (id == "") {
    document.getElementById("Error101").style.display = "block";
  } else if (gdpa == "") {
    document.getElementById("Error101").style.display = "block";
  } else {
    document.getElementById("Succes101").style.display = "block";
    x = 1;
  }
  setTimeout(function() {
    document.getElementById("Error101").style.display = "none";
    document.getElementById("Succes101").style.display = "none";
  }, 3000);
}

function insertStudent(name, id, gdpa) {
  let student = {
    name: name,
    id: id,
    gdpa: gdpa,
  };
  students.push(student);
  console.log("students array: ", students);
  x = 0;
}

function showList() {
  students.forEach(element => {
    document.getElementById("showLi").innerHTML = (students);
  });
}

  2. You mean this

    document.getElementById("showLi").innerHTML = students
 .map(({name,id,gdpa}) => `<li>name: ${name}, id: ${id}, gdpa: ${gdpa}</li>`)
 .join("");

    ALSO change

    <button id="submit" type="submit">Add</button>

    to

    <button id="add" type="button">Add</button>

    and change

    document.getElementById("submit").addEventListener("click", (e) => {

    to

    document.getElementById("add").addEventListener("click", (e) => {

    let students = [];
let x = 0;
document.getElementById("add").addEventListener("click", (e) => {
  e.preventDefault();
  let nameInputEl = document.getElementById("name");
  let idInputEl = document.getElementById("idNumber");
  let gdpaInputEl = document.getElementById("gdpa");

  // Validation for input
  inputValidation(nameInputEl.value, idInputEl.value, gdpaInputEl.value);

  // insert student
  if (x == 1) {
    insertStudent(nameInputEl.value, idInputEl.value, gdpaInputEl.value);
  }

  // showList(); // uncomment to make you push the show
});

function inputValidation(name, id, gdpa) {
  // check for the value of each element

  if (name == "") {
    document.getElementById("Error101").style.display = "block";
  } else if (id == "") {
    document.getElementById("Error101").style.display = "block";
  } else if (gdpa == "") {
    document.getElementById("Error101").style.display = "block";
  } else {
    document.getElementById("Succes101").style.display = "block";
    x = 1;
  }
  setTimeout(function() {
    document.getElementById("Error101").style.display = "none";
    document.getElementById("Succes101").style.display = "none";
  }, 3000);
}

function insertStudent(name, id, gdpa) {
  let student = {
    name: name,
    id: id,
    gdpa: gdpa,
  };
  students.push(student);
  console.log("students array: ", students);
  x = 0;
}

function showList() {
  document.getElementById("showLi").innerHTML = students
    .map(({
      name,
      id,
      gdpa
    }) => `<li>name: ${name}, id: ${id}, gdpa: ${gdpa}</li>`)
    .join("");

    Here is YOUR code with ONLY my change and <ol id="ShowLi"></ol>

    let students = [];
let x = 0;
document.getElementById("submit").addEventListener("click", (e) => {
  e.preventDefault();
  let nameInputEl = document.getElementById("name");
  let idInputEl = document.getElementById("idNumber");
  let gdpaInputEl = document.getElementById("gdpa");

  // Validation for input
  inputValidation(nameInputEl.value, idInputEl.value, gdpaInputEl.value);

  // insert student
  if (x == 1) {
    insertStudent(nameInputEl.value, idInputEl.value, gdpaInputEl.value);
  }

  // Show success message
});

function inputValidation(name, id, gdpa) {
  // check for the value of each element

  if (name == "") {
    document.getElementById("Error101").style.display = "block";
  } else if (id == "") {
    document.getElementById("Error101").style.display = "block";
  } else if (gdpa == "") {
    document.getElementById("Error101").style.display = "block";
  } else {
    document.getElementById("Succes101").style.display = "block";
    x = 1;
  }
  setTimeout(function() {
    document.getElementById("Error101").style.display = "none";
    document.getElementById("Succes101").style.display = "none";
  }, 3000);
}

function insertStudent(name, id, gdpa) {
  let student = {
    name: name,
    id: id,
    gdpa: gdpa,
  };
  students.push(student);
  console.log("students array: ", students);
  x = 0;
}

function showList() {
  document.getElementById("ShowLi").innerHTML = students
    .map(({name,id,gdpa}) => `<li>name: ${name}, id: ${id}, gdpa: ${gdpa}</li>`)
    .join("");
