问题：
With jQuery, how do I find out which key was pressed when I bind to the keypress event? 使用jQuery，如何确定绑定到keypress事件时按下了哪个键？
$('#searchbox input').bind('keypress', function(e) {});
I want to trigger a submit when ENTER is pressed. 我想在按ENTER键时触发提交。

Even though I found the (or better: one) answer myself, there seems to be some room for variation ;) 即使我找到了（或者更好：一个）自己回答，似乎还有一些变化的空间;）
Is there a difference between keyCode and which - especially if I'm just looking for ENTER , which will never be a unicode key? 有没有之间的差异keyCode和which -尤其是如果我只是在寻找ENTER，这将永远是一个unicode关键？
Do some browsers provide one property and others provide the other one? 有些浏览器提供一种属性，而其他浏览器提供另一种属性吗？
