我已经使用此代码禁用输入类型[文本]和输入类型[密码]上的“ENTER”键，您可以添加其他太像输入类型[电子邮件]或也可以应用于您所需的输入类型。

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

一个漂亮的简单的jQuery解决方案:

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

为了阻止表单被提交，我必须捕获所有与按下键相关的三个事件:

    var preventSubmit = function(event) {
        if(event.keyCode == 13) {
            console.log("caught ya!");
            event.preventDefault();
            //event.stopPropagation();
            return false;
        }
    }
    $("#search").keypress(preventSubmit);
    $("#search").keydown(preventSubmit);
    $("#search").keyup(preventSubmit);

你可以把上面所有的组合成一个漂亮的紧凑版本:

    $('#search').bind('keypress keydown keyup', function(e){
       if(e.keyCode == 13) { e.preventDefault(); }
    });

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

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>
