I’m doing a school project (an automatic bingo), and I’m on the last step, compare the raffled value with the values added by users, I’m around a week trying to do this, if anyone can help me solve my problem, I really appreciate it!

Last topic: Every 4 seconds a number is drawn, and as soon as it is drawn I have to compare it with all users, so that if any possess I can mark it (with a div, or some syllable)then I can check which of the players has all the numbers marked and so power a winner alert.

Here follows the functions I used to expose the values (both those chosen by the user, and what will be drawn);

<script type="text/javascript">

      function novoUsuario(idTabela) {
        var tabela = document.getElementById(idTabela);
        var numeroLinhas = tabela.rows.length;
        var linha = tabela.insertRow(numeroLinhas);
        var nome = linha.insertCell(0);
        var nu = linha.insertCell(1);   
        var nd = linha.insertCell(2); 
        var nt = linha.insertCell(3);
        var nq = linha.insertCell(4);
        var nc = linha.insertCell(5);
        var botao = linha.insertCell(6);

        nome.innerHTML = document.getElementById('nome').value;
        nome.setAttribute("class","font-weight-bold");

        n1 = parseInt( document.getElementById('numero').value);
        n2 = parseInt( document.getElementById('numer').value);
        n3 = parseInt( document.getElementById('nume').value);
        n4 = parseInt( document.getElementById('num').value);
        n5 = parseInt( document.getElementById('nu').value);

        nu.innerHTML = n1;
        nd.innerHTML = n2;
        nt.innerHTML = n3;
        nq.innerHTML = n4;
        nc.innerHTML = n5;

        botao.innerHTML =  "<button onclick='removeLinha(this)' class='btn-outline-danger btn-sm btn'>Remover</button>"; 

        if (n1<1 || n1>75) {
          alert("Valores inadequados, por favor, exclua o usuário e adicione novamente, escolhendo números entre 1 e 75");
        }
      }

      var tempo = setInterval(sortear, 4000);


      function parar() {
        clearInterval(tempo);
      }

      function sortear() {
        var sorte = Math.floor(Math.random() * 75 + 1);
        document.getElementById('mostrar').innerHTML = sorte;
      }    

      function removeLinha(linha) {
        var i=linha.parentNode.parentNode.rowIndex;
        document.getElementById('tabela').deleteRow(i);
      }      

      

      function somenteNumeros(num) {
        var er = /[^0-9.]/;
        er.lastIndex = 0;
        var campo = num;
        if (er.test(campo.value)) {
          campo.value = "";
          alert("digite um número");
        }
    }

    </script>

<style type="text/css">
      td{ text-align: center }
      th{ text-align: center }
      body{background: url("fundo2.jpg")}
      #m{background: url("fundo5.gif")}
      .cor{background-color: black}

I’m not sure I understand, but I believe you want to identify in the table which names with the drawn number.

A loop in the table elements should help.

  function sortear() {
    var sorte = Math.floor(Math.random() * 75 + 1);
    document.getElementById('mostrar').innerHTML = sorte;
    ganhadores(sorte, "tabela");
  }

  // Recebe como paramentro o numero sorteado e o id da tabela
  function ganhadores(num, tabelaID) {
    var tabela = document.getElementById(tabelaID), // obter a tabela pelo id
      cell;
    // Loop em cada linha da tabela
    for (var row = 0; row < tabela.rows.length; row++) {
      var contador = 0; // Contador para verificar vencedor
      cell = tabela.rows[row].getElementsByTagName("td"); // obter todas as colunas da tabela
      // Loop em cada coluna
      for (var i = 1; i < cell.length; i++) {
        // Verifica se o numero ja foi sorteado
        if (!cell[i].getAttribute("sorteado")) {
          // Verificar se o numero do usuário é igual ao sorteado
          if (parseInt(cell[i].innerHTML) === num) {
            // definir tag para lembrar que o numero já foi sorteador
            cell[i].setAttribute("sorteado", true);
            // colorir o numero de verde
            cell[i].setAttribute("style", "color: green");
            contador++;
          }
        } else {
          // Incrementar contador
          contador++;
        }

        // Verificar se o contador é igual a 5
        if (contador >= 5) {
          // Definir nome do vencedor de verde
          cell[0].setAttribute("style", "color: green");
          alert("Vencedor: " + cell[0].innerHTML);
          parar();
        }

      }
    } 
  }
