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.

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。

[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;

如何:

<asp:Button ID="button" UseSubmitBehavior="false"/>

这对我很管用。 onkeydown = "返回! (event.keyCode = = 13)”

    <form id="form1" runat="server" onkeydown="return !(event.keyCode==13)">

   </form>

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。
