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!');}
    );
});

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>

这是我达到目标的解决方案， 它干净有效。

$('form').submit(function () {
  if ($(document.activeElement).attr('type') == 'submit')
     return true;
  else return false;
});

您可以使用一种方法，例如

$(document).ready(function() {
  $(window).keydown(function(event){
    if(event.keyCode == 13) {
      event.preventDefault();
      return false;
    }
  });
});

在阅读原文的评论时，为了让它更有用，并允许人们在填写完所有字段后按Enter:

function validationFunction() {
  $('input').each(function() {
    ...

  }
  if(good) {
    return true;
  }
  return false;
}

$(document).ready(function() {
  $(window).keydown(function(event){
    if( (event.keyCode == 13) && (validationFunction() == false) ) {
      event.preventDefault();
      return false;
    }
  });
});

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>
