$(document).on("keydown","form", function(event)
{
   node = event.target.nodeName.toLowerCase();
   type = $(event.target).prop('type').toLowerCase();

   if(node!='textarea' && type!='submit' && (event.keyCode == 13 || event.keyCode == 169))
   {
        event.preventDefault();
        return false;
    }
});

它工作得很完美!

我还不能评论，所以我会发布一个新的答案

接受的答案是ok-ish，但它不是停止提交在numpad进入。至少在当前版本的Chrome中是这样。我不得不改变这个键码条件，然后它工作。

if(event.keyCode == 13 || event.keyCode == 169) {...}

您可以创建一个JavaScript方法来检查是否按下了Enter键，如果按下了，就停止提交。

<script type="text/javascript">
  function noenter() {
  return !(window.event && window.event.keyCode == 13); }
</script>

只需在submit方法上调用它。

我在这里没有看到答案:当您通过页面上的元素时，当您到达提交按钮时按Enter将触发表单上的onsubmit处理程序，但它将记录事件为MouseEvent。以下是我的简单解决方案:

这不是一个与jquery相关的答案

HTML

<form onsubmit="return false;" method=post>
  <input type="text" /><br />
  <input type="button" onclick="this.form.submit()" value="submit via mouse or keyboard" />
  <input type="button" onclick="submitMouseOnly(event)" value="submit via mouse only" />
</form>

JavaScript

window.submitMouseOnly=function(evt){
    let allow=(evt instanceof MouseEvent) && evt.x>0 && evt.y>0 && evt.screenX > 0 && evt.screenY > 0;
    if(allow)(evt.tagName=='FORM'?evt.target:evt.target.form).submit();
}

要找到一个工作示例:https://jsfiddle.net/nemesarial/6rhogva2/

只有块提交，而不是其他，重要的功能输入键，如创建一个新的段落在<textarea>:

window.addEventListener('keydown', function(event) { //set default value for variable that will hold the status of keypress pressedEnter = false; //if user pressed enter, set the variable to true if (event.keyCode == 13) pressedEnter = true; //we want forms to disable submit for a tenth of a second only setTimeout(function() { pressedEnter = false; }, 100) }) //find all forms var forms = document.getElementsByTagName('form') //loop through forms for (i = 0; i < forms.length; i++) { //listen to submit event forms[i].addEventListener('submit', function(e) { //if user just pressed enter, stop the submit event if (pressedEnter == true) { updateLog('Form prevented from submit.') e.preventDefault(); return false; } updateLog('Form submitted.') }) } var log = document.getElementById('log') updateLog = function(msg) { log.innerText = msg } input, textarea { display: inline-block; margin-bottom: 1em; border: 1px solid #6f6f6f; padding: 5px; border-radius: 2px; width: 90%; font-size: 14px; } input[type=submit] { background: lightblue; color: #fff; } <form> <p>Sample textarea (try enter key):</p> <textarea rows="4">Hit enter, a new line will be added. But the form won't submit</textarea><br/> <p>Sample textfield (try enter key):</p> <input type="text" placeholder="" /> <br/> <input type="submit" value="Save" /> <h3 id="log"></h3> </form>

你也可以使用javascript:void(0)来阻止表单提交。

<form action="javascript:void(0)" method="post">
    <label for="">Search</label>
    <input type="text">
    <button type="sybmit">Submit</button>
</form>

<form action="javascript:void(0)" method="post"> <标签= " " > < / >标签搜索 < input type = " text " > <按钮类型=“sybmit”> > < /按钮提交 > < /形式
