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>

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>

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>

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。

这将禁用页面上所有表单的输入键，并且不阻止在文本区域输入。

    // disable form submit with enter

    $('form input:not([type="submit"])').keydown((e) => {
        if (e.keyCode === 13) {
            e.preventDefault();
            return false;
        }
        return true;
    });

在我对其他解决方案感到沮丧之后，这在所有浏览器中都有效。name_space外层函数只是为了避免声明全局变量，这也是我推荐的。

$(function() {window.name_space = new name_space();}); //jquery doc ready
function name_space() {
    this.is_ie = (navigator.userAgent.indexOf("MSIE") !== -1);

    this.stifle = function(event) {
        event.cancelBubble;
        event.returnValue = false;
        if(this.is_ie === false) {
            event.preventDefault();
        }
        return false;
    }

    this.on_enter = function(func) {
        function catch_key(e) {
            var enter = 13;
            if(!e) {
                var e = event;
            }
            keynum = GetKeyNum(e);
            if (keynum === enter) {
                if(func !== undefined && func !== null) {
                    func();
                }
                return name_space.stifle(e);
            }
            return true; // submit
        }

        if (window.Event) {
            window.captureEvents(Event.KEYDOWN);
            window.onkeydown = catch_key;
        }
        else {
            document.onkeydown = catch_key;
        }

        if(name_space.is_ie === false) {
            document.onkeypress = catch_key;    
        }
    }
}

示例使用:

$(function() {
    name_space.on_enter(
        function () {alert('hola!');}
    );
});
