给表单一个'javascript:void(0);'的动作似乎可以做到这一点

<form action="javascript:void(0);">
<input type="text" />
</form>
<script>
$(document).ready(function() {
    $(window).keydown(function(event){
        if(event.keyCode == 13) {
    alert('Hello');
        }
    });
});
</script>

一个漂亮的简单的jQuery解决方案:

$("form").bind("keypress", function (e) {
    if (e.keyCode == 13) {
        return false;
    }
});

这是我达到目标的解决方案， 它干净有效。

$('form').submit(function () {
  if ($(document.activeElement).attr('type') == 'submit')
     return true;
  else return false;
});

您可以使用一种方法，例如

$(document).ready(function() {
  $(window).keydown(function(event){
    if(event.keyCode == 13) {
      event.preventDefault();
      return false;
    }
  });
});

在阅读原文的评论时，为了让它更有用，并允许人们在填写完所有字段后按Enter:

function validationFunction() {
  $('input').each(function() {
    ...

  }
  if(good) {
    return true;
  }
  return false;
}

$(document).ready(function() {
  $(window).keydown(function(event){
    if( (event.keyCode == 13) && (validationFunction() == false) ) {
      event.preventDefault();
      return false;
    }
  });
});

如果使用Vue，使用以下代码来阻止用户通过按Enter提交表单:

<form @submit.prevent>...</form>

第4.10.22.2节隐式提交的W3C HTML5规范说:

A form element's default button is the first submit button in tree order whose form owner is that form element. If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button. Note: Consequently, if the default button is disabled, the form is not submitted when such an implicit submission mechanism is used. (A button has no activation behavior when disabled.)

因此，一种符合标准的禁用表单隐式提交的方法是将禁用的提交按钮作为表单中的第一个提交按钮:

<form action="...">
  <!-- Prevent implicit submission of the form -->
  <button type="submit" disabled style="display: none" aria-hidden="true"></button>

  <!-- ... -->

  <button type="submit">Submit</button>
</form>

这种方法的一个很好的特性是它不需要JavaScript;无论是否启用JavaScript，都需要一个符合标准的web浏览器来防止隐式表单提交。
