在没有提交按钮的情况下，按下回车键即可提交表单

问题描述：

我有一个没有提交按钮的表单，如果在用户按下Enter键时仍然提交表单，那就太好了.我尝试添加一个隐藏的提交按钮，这使我在Safari，Firefox和Chrome浏览器中具有所需的行为，但是该表单仍未在IE中提交.有标准的方法吗?

I've got a form that has no submit button and it would be great if the form is still submitted when the user hits the enter key. I've tried adding a hidden submit button, which gives me the desired behavior in Safari, Firefox and Chrome, but the form is still not submitted in IE. Is there a standard way of doing this?

答

经过测试/跨浏览器:

function submitOnEnter(e) {
    var theEvent = e || window.event;
    if(theEvent.keyCode == 13) {
        this.submit;
    }
    return true;
}
document.getElementById("myForm").onkeypress = function(e) { return submitOnEnter(e); }

<form id="myForm">
<input type="text"/>
...
</form>

如果没有提交"按钮，则在无法使用javascript的情况下，表单将严重恶化！

If there is no submit button, the form will degrade miserably if javascript is not available!
