jQuery Event Keypress:按下了哪个键?

jQuery Event Keypress: Which key was pressed?(jQuery Event Keypress:按下了哪个键?)

问题描述

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

$('#searchbox input').bind('keypress', function(e) {});

I want to trigger a submit when ENTER is pressed.

[Update]

Even though I found the (or better: one) answer myself, there seems to be some room for variation ;)

Is there a difference between keyCode and which - especially if I'm just looking for ENTER, which will never be a unicode key?

Do some browsers provide one property and others provide the other one?

Actually this is better:

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