Question

With jQuery, how do I find out which key was pressed when I bind to the keypress event?

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？)

 var code = e.keyCode || e.which;
 if(code == 13) { //Enter keycode
   //Do something
 }
