如何从html表单获取值到javascript

<form id="myForm">
  <label for="name">姓名：</label>
  <input type="text" id="name" name="name"><br><br>
  <label for="email">邮箱：</label>
  <input type="email" id="email" name="email"><br><br>
  <input type="submit" value="提交">
</form>

var form = document.getElementById("myForm");
var nameInput = document.getElementById("name");
var emailInput = document.getElementById("email");

var form = document.forms["myForm"];
var nameInput = form.elements["name"];
var emailInput = form.elements["email"];

form.addEventListener("submit", function(event) {
  event.preventDefault(); // 阻止表单提交
  // 在这里处理表单数据
});

form.addEventListener("submit", function(event) {
  event.preventDefault();
  
  var name = nameInput.value;
  var email = emailInput.value;
  
  // 在这里处理表单数据
});
