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>

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

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>

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>

一个漂亮的简单的jQuery解决方案:

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

我需要防止只提交特定的输入，所以我使用了一个类选择器，让它成为我需要的“全局”特性。

<input id="txtEmail" name="txtEmail" class="idNoEnter" .... />

jQuery代码:

$('.idNoEnter').keydown(function (e) {
  if (e.keyCode == 13) {
    e.preventDefault();
  }
});

或者，如果keydown不够用:

$('.idNoEnter').on('keypress keydown keyup', function (e) {
   if (e.keyCode == 13) {
     e.preventDefault();
   }
});

一些注意事项:

在这里修改各种不错的答案，Enter键似乎适用于所有浏览器的keydown。对于替代方法，我将bind()更新为on()方法。

我是类选择器的忠实粉丝，权衡所有的利弊和性能讨论。我的命名约定是'idSomething'，表示jQuery将其用作id，以将其与CSS样式分开。
