jQuery 事件按键:按下了哪个键? [英] jQuery Event Keypress: Which key was pressed?

问题描述

使用 jQuery，如何在绑定到 keypress 事件时找出按下了哪个键?

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

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

我想在按下 ENTER 时触发提交.

I want to trigger a submit when ENTER is pressed.

[更新]

即使我自己找到了(或更好的:一个)答案，似乎仍有一些变化的空间;)

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

keyCode 和 which 之间有区别吗 - 特别是如果我只是在寻找 ENTER，它永远不会是一个 unicode 键?

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

某些浏览器是否提供一种属性而其他浏览器提供另一种属性?

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

推荐答案

其实这样更好:

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