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。

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(); }
    });
});

一个漂亮的简单的jQuery解决方案:

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

Use:

// Validate your form using the jQuery onsubmit function... It'll really work...

$(document).ready(function(){
   $(#form).submit(e){
       e.preventDefault();
       if(validation())
          document.form1.submit();
   });
});

function validation()
{
   // Your form checking goes here.
}

<form id='form1' method='POST' action=''>
    // Your form data
</form>

使用Javascript(不检查任何输入字段):

<script>
window.addEventListener('keydown', function(e) {
    if (e.keyIdentifier == 'U+000A' || e.keyIdentifier == 'Enter' || e.keyCode == 13) {
        e.preventDefault();
        return false;
    }
}, true);
</script>

如果有人想将此应用于特定的字段，例如输入类型text:

<script>
window.addEventListener('keydown', function(e) {
    if (e.keyIdentifier == 'U+000A' || e.keyIdentifier == 'Enter' || e.keyCode == 13) {
        if (e.target.nodeName == 'INPUT' && e.target.type == 'text') {
            e.preventDefault();
            return false;
        }
    }
}, true);
</script>

这对我来说很有效。

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>
