Use:

$(document).on('keyup keypress', 'form input[type="text"]', function(e) {
  if(e.keyCode == 13) {
    e.preventDefault();
    return false;
  }
});

这个解决方案适用于网站上的所有表单(也适用于使用Ajax插入的表单)，只防止输入文本中的enter。把它放在文档就绪函数中，然后永远忘记这个问题。

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>

在我的情况下，我有一对jQuery UI自动完成字段和文本区域的形式，所以我肯定希望他们接受进入。所以我从表单中删除了type="submit"输入，并添加了一个锚<a href="" id="btn">Ok</a>。然后我把它设置为一个按钮，并添加以下代码:

$( '#btn' ).click( function( event ){
    event.preventDefault();
    if ( validateData() ){
        $( 'form#frm' ).append( '<input type="submit" id="frm-submit" style="display:none;"></input>' );
        setTimeout( function(){ $( '#frm-submit' ).click(); }, 500 );
    }
    return false;
});

如果用户填写了所有必需的字段，validateData()将成功并提交表单。

一种完全不同的方法:

The first <button type="submit"> in the form will be activated on pressing Enter. This is true even if the button is hidden with style="display:none; The script for that button can return false, which aborts the submission process. You can still have another <button type=submit> to submit the form. Just return true to cascade the submission. Pressing Enter while the real submit button is focussed will activate the real submit button. Pressing Enter inside <textarea> or other form controls will behave as normal. Pressing Enter inside <input> form controls will trigger the first <button type=submit>, which returns false, and thus nothing happens.

因此:

<form action="...">
  <!-- insert this next line immediately after the <form> opening tag -->
  <button type=submit onclick="return false;" style="display:none;"></button>

  <!-- everything else follows as normal -->
  <!-- ... -->
  <button type=submit>Submit</button>
</form>

这对我很有用

jQuery.each($("#your_form_id").find('input'), function(){
    $(this).bind('keypress keydown keyup', function(e){
       if(e.keyCode == 13) { e.preventDefault(); }
    });
});

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>
