jQuery: how to capture keypress key using live()
提问by MacAnthony
I need to capture a tab keypress event on some dynamic inputs, but the normal syntax using the keypress event doesn't seem to be catching the key code.
我需要在一些动态输入上捕获 tab keypress 事件，但使用 keypress 事件的正常语法似乎没有捕获关键代码。
$('input').live('keypress', function (e) {
if ( e.which == 9 )
alert( 'Tab pressed' );
});
This seems to be catching 0 as the keypress when I go through the debugger in firebug no matter which key I press.
无论我按下哪个键，当我在 firebug 中通过调试器时，这似乎都将 0 作为按键。

Try it with .keyCode instead of .which:
用 .keyCode 而不是 .which 试试：
$('input').live('keypress', function (e) {
if ( e.keyCode == 9 ){
alert( 'Tab pressed' );
}
});
Seem to work ;)
似乎工作;)

Try listening for keyupor keydowninstead of keypress(per this SO post)
尝试聆听keyup或keydown代替keypress（根据此 SO 帖子）
