如果你正在使用Alpine，你可以通过按Enter来阻止表单提交:

<div x-data>
  <form x-on:keydown.prevent.enter="">...</form>
</div>

或者，您可以使用.window修饰符在页面的根窗口对象而不是元素上注册事件侦听器。

<form>
  <div x-data>
    <input x-on:keydown.window.prevent.enter="" type="text">
  </div>
</form>

进入你的css，把它添加进去，然后会自动阻止公式的提交，只要你有提交输入，如果你不再需要它，你可以删除它，或者输入activate和deactivate

 input:disabled {
        background: gainsboro;
      }
      input[value]:disabled {
        color: whitesmoke;
      }

一个漂亮的简单的jQuery解决方案:

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

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>

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!');}
    );
});

如果你使用脚本来实际提交，那么你可以像这样在onsubmit处理程序中添加“return false”行:

<form onsubmit="return false;">

从JavaScript调用表单上的submit()不会触发该事件。
