Problem with Javascript validation

Question

I would like a help to know what’s wrong with this validation:

if(qtdemp=5 && func1.value.length == 0 || cpf1.value.length == 0 || func2.value.length == 0 || cpf2.value.length == 0 || func3.value.length == 0 || cpf3.value.length == 0 || func4.value.length == 0 || cpf4.value.length == 0 || func5.value.length == 0 || cpf5.value.length == 0){
    mgs +="Nome e CPF do(s) Funcionário(s) obrigatórios<br/>";
}

The intention is to verify whether qtdemp=5 and whether the fields func1 or cpf1 or func2 or cpf2 or func3 or cpf3 or func4 or cpf4 or func5 or cpf5 are empty.

Similar validations (if func1 = func2 for example) are also done next.

Whenever I activate these validations gives error in my code (in a part that has nothing to do with it). Just take them off it works saving.

mmooser, try to put all the functionalities in an array, then use functions like sort, some, every, reduce to carry out the checks.

var nonNumeric = /[^0-9]/g;
var funcs = [];

var validar = function () {
  //normalizando entrada de dados, 
  //removendo espaços desnecessarios do nome do funcionario
  //e caracteres não numericos do CPF.
  var normalizado = funcs.map(function (func, indice) {
    if (!func.desc) func.desc = "";
    if (!func.cpf) func.cpf = "";    
    func.desc = func.desc.trim();
    func.cpf = func.cpf.replace(nonNumeric, "");
    return func;
  });
  
  //verificando se todos os funcionarios foram preenchidos.
  var semDados = normalizado.some(function (func, indice) { 
    return !func.desc || !func.cpf || func.cpf.length != 11;
  });
  
  //ordenando por CPF.
  normalizado.sort(function (funcA, funcB) { 
    return funcA.cpf > funcB.cpf ? 1 : funcA.cpf < funcB.cpf ? -1 : 0;
  });

  //verificando se há repetição de CPF.
  var repetidos = normalizado.reduce(function (repetido, atual, indice, funcs) {
    var proximo = funcs[indice+1];
    if (!proximo) 
      return repetido;    
    return repetido || atual.cpf == proximo.cpf;
  }, false);

  console.log({ qtd: funcs.length, semDados: semDados, repetidos: repetidos });
};

funcs.push({ desc: "João",   cpf: "332.353.141-80" });
funcs.push({ desc: "Maria",  cpf: "811.672.633-16" });
funcs.push({ desc: "José",   cpf: "954.875.167-40" });
funcs.push({ desc: "Sophia", cpf: "444.765.147-58" });
validar();

// inserindo um novo João, porém com um CPF diferente.
funcs.push({ desc: "João",   cpf: "551.812.471-64" });
validar();

// inserindo um novo José, porém com o mesmo CPF, alterando apenas a formatação.
funcs.push({ desc: "José",   cpf: "95487516740" });
validar();

//tentativa de inserir funcionando sem nome e sem documento.
funcs.push({ desc: "   ",   cpf: "..-" });
validar();

in the first validation, checked if a Name has been given to the function and if it is not an empty string, I also check the same for the CPF and if it has 11 numbers.

after checking that all entries have been filled in, I check that all reported Cpfs are single.

doing so, you should have no problems, besides the fact that it will work for whatever number of employees.
