如何在禁用调整大小的情况下向弹出窗口提交HTML表单？

var myWindow = window.open("", "", "width=500, height=400, resizable=no");

<form id="myForm">
 <label for="name">Name:</label>
 <input type="text" id="name" name="name"><br>
 <label for="email">Email:</label>
 <input type="email" id="email" name="email"><br>
 <input type="submit" value="Submit">
</form>

document.getElementById("myForm").addEventListener("submit", function(event){
  event.preventDefault();
  var xhr = new XMLHttpRequest();
  xhr.open("POST", "your-server-url-here", true);
  xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
  xhr.onreadystatechange = function() {
    if (xhr.readyState === 4 && xhr.status === 200) {
      alert("Form submitted successfully!");
      myWindow.close();
    }
  };
  var formData = new FormData(event.target);
  xhr.send(formData);
});
