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(); }
    });
});

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(); }
    });

$(document).on("keydown","form", function(event)
{
   node = event.target.nodeName.toLowerCase();
   type = $(event.target).prop('type').toLowerCase();

   if(node!='textarea' && type!='submit' && (event.keyCode == 13 || event.keyCode == 169))
   {
        event.preventDefault();
        return false;
    }
});

它工作得很完美!

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;
    });

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。

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>
