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.

我花了一些时间制作这款跨浏览器，适用于IE8、9、10、Opera 9+、Firefox 23、Safari(PC)和Safari(MAC)

示例:http://jsfiddle.net/greatbigmassive/ZyeHe/

基本代码-通过“onkeypress”附加到您的窗体和传递窗口调用此函数。事件”。

function stopEnterSubmitting(e) {
    if (e.keyCode == 13) {
        var src = e.srcElement || e.target;
        if (src.tagName.toLowerCase() != "textarea") {
            if (e.preventDefault) {
                e.preventDefault();
            } else {
                e.returnValue = false;
            }
        }
    }
}

简而言之，纯Javascript的答案是:

<script type="text/javascript">
    window.addEventListener('keydown', function(e) {
        if (e.keyIdentifier == 'U+000A' || e.keyIdentifier == 'Enter' || e.keyCode == 13) {
            if (e.target.nodeName == 'INPUT' && e.target.type == 'text') {
                e.preventDefault();
                return false;
            }
        }
    }, true);
</script>

这只会禁用input type='text'的"Enter"键动作。访问者仍然可以在整个网站上使用“Enter”键。

如果你想在其他操作中禁用“Enter”，你可以添加console.log(e);为了你的测试目的，在chrome中按F12，进入“控制台”选项卡，点击页面上的“backspace”，看看里面返回了什么值，然后你可以针对所有这些参数来进一步增强上面的代码，以满足你对“e.t target”的需求。节点名”、“e。target。键入”和更多…

在这里可以看到我对类似问题的详细回答

如何:

<script>
function isok(e) {
  var name = e.explicitOriginalTarget.name;
  if (name == "button") {
    return true
  }
  return false;
}
</script>
<form onsubmit="return isok(event);">
<input type="text" name="serial"/>
<input type="submit" name="button" value="Create Thing"/>
</form>

只要给你的按钮命名，它仍然会提交，但文本字段，即显式originaltarget，当你在其中点击返回时，将没有正确的名称。

我在这里或其他帖子中找到的所有关于这个主题的答案都有一个缺点，那就是它阻止了表单元素上的实际更改触发器。所以如果你运行这些解决方案，onchange事件也不会被触发。为了克服这个问题，我修改了这些代码，并为自己开发了以下代码。我希望这对其他人有用。 我给了一个类我的表单“prevent_auto_submit”，并添加以下JavaScript:

$(document).ready(function() 
{
    $('form.prevent_auto_submit input,form.prevent_auto_submit select').keypress(function(event) 
    { 
        if (event.keyCode == 13)
        {
            event.preventDefault();
            $(this).trigger("change");
        }
    });
});
