stopSubmitOnEnter (e) {
  var eve = e || window.event;
  var keycode = eve.keyCode || eve.which || eve.charCode;

  if (keycode == 13) {
    eve.cancelBubble = true;
    eve.returnValue = false;

    if (eve.stopPropagation) {   
      eve.stopPropagation();
      eve.preventDefault();
    }

    return false;
  }
}

然后在表格上:

<form id="foo" onkeypress="stopSubmitOnEnter(e);">

不过，如果不使用突兀的JavaScript会更好。

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.

将这个标签添加到你的表单- onsubmit="return false;" 然后只能使用JavaScript函数提交表单。

在我的案例中，这个jQuery JavaScript解决了这个问题

jQuery(function() {
            jQuery("form.myform").submit(function(event) {
               event.preventDefault();
               return false;
            });
}

请查看这篇文章如何防止按ENTER键提交web表单?

$(“.pc_prevent_submit”)时函数(){ 美元(窗口).keydown(函数(事件){ 如果事件。keyCode == 13) { event.preventDefault (); 返回错误; ｝ })； })； < script src = " https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js " > < /脚本> <form class= " pc_prevent_submit " action= " " method= " post " > <input type= " text " name= " username " > <input type= " password " name= " userpassword " > <input type= " submit " value= " submit " > > < /形式

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;
 });
});
