How do I go to the thank you page after a successful submission?

• 0
  There is such a code in pure JS.
  Tell me what needs to be removed here or what should be added so that after a successful submission I will be redirected to the thank you page?
  

  form.addEventListener("submit", (e) => {
    e.preventDefault();
  
    const phoneInput = document.getElementById("quiz-phone");
    const emailInput = document.getElementById("quiz-email");
  
    answersObj.step4.phone = phoneInput.value;
    answersObj.step4.email = emailInput.value;
  
    if (phoneInput.value === "" || emailInput.value === "") {
      alert("Введите данные формы");
    } else if(emailInput.classList.contains('error')) {
      alert("Введите верный email");
    } else if(phoneInput.classList.contains('error')) {
      alert("Введите верный номер телефона");
    } else {
      postData(answersObj)
        .then((res) => res.json())
        .then((res) => {
          if (res.result === "success") {
            window.location = "/thanks.html";
            form.reset();
          } else {
            alert(res.status);
          }
        });
    }
  });
  
  const postData = (body) => {
    return fetch("./quiz-send.php", {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify(body),
    });
  };

  
  
  The send.php file contains header ('Location: thanks.html');
  
  At the moment, the form is being sent, but as already understood, it does not translate to the thanks page :(

  Most likely, the page does not go to the page because the fetch request ends with an error.
  
  Catch the error using catch
  
  

  postData(answersObj)
  
        .then((res) => res.json())
  
        .then((res) => {
  
          if (res.result === "success") {
  
            window.location = "/thanks.html";
  
            form.reset();
  
          } else {
  
            alert(res.status);
  
          }
  
        })
  
        .catch(err=>alert(err.message)); // ошибка отправки формы
