这是一个jQuery处理程序，可以用来停止输入提交，也停止退格键->返回。"keyStop"对象中的(keyCode: selectorString)对用于匹配不应该触发默认动作的节点。

记住，网络应该是一个可访问的地方，这打破了键盘用户的期望。也就是说，在我的情况下，我正在工作的web应用程序不喜欢后退按钮，所以禁用它的快捷键是可以的。“应该输入->提交”的讨论很重要，但与实际提出的问题无关。

以下是代码，由您自行考虑可访问性以及为什么要这样做!

$(function(){
 var keyStop = {
   8: ":not(input:text, textarea, input:file, input:password)", // stop backspace = back
   13: "input:text, input:password", // stop enter = submit 

   end: null
 };
 $(document).bind("keydown", function(event){
  var selector = keyStop[event.which];

  if(selector !== undefined && $(event.target).is(selector)) {
      event.preventDefault(); //stop event
  }
  return true;
 });
});

我认为，你可以在javascript的表单中捕获键下，防止冒泡。网页上的ENTER基本上只是提交当前所选控件所在的表单。

放入javascript外部文件

   (function ($) {
 $(window).keydown(function (event) {  

    if (event.keyCode == 13) {

        return false;
    }
});

 })(jQuery);

或者在body tag里面

<script>


$(document).ready(function() {
    $(window).keydown(function(event) {
        alert(1);

        if(event.keyCode == 13) {

            return false;
        }
    });
});

</script>

[2012修订版，没有内联处理程序，保留textarea进入处理]

function checkEnter(e){
 e = e || event;
 var txtArea = /textarea/i.test((e.target || e.srcElement).tagName);
 return txtArea || (e.keyCode || e.which || e.charCode || 0) !== 13;
}

现在你可以在表单上定义一个按键处理程序: <形式[…onkeypress="return checkEnter(event)">

document.querySelector('form').onkeypress = checkEnter;

I Have come across this myself because I have multiple submit buttons with different 'name' values, so that when submitted they do different things on the same php file. The enter / return button breaks this as those values aren't submitted. So I was thinking, does the enter / return button activate the first submit button in the form? That way you could have a 'vanilla' submit button that is either hidden or has a 'name' value that returns the executing php file back to the page with the form in it. Or else a default (hidden) 'name' value that the keypress activates, and the submit buttons overwrite with their own 'name' values. Just a thought.

只需从onsubmit处理程序返回false

<form onsubmit="return false;">

或者如果你想要一个中间的处理程序

<script>
var submitHandler = function() {
  // do stuff
  return false;
}
</script>
<form onsubmit="return submitHandler()">
