jquery - capturing document level keypress events with javascript - Stack Overflow

i've been trying to capture document level key press events in a webpage but

$(document).bind('keydown', 'a', keyevent_cb);

fails to respond consistently in firefox. works great in IE (which is kind of a trip). any remendations? i've attempted other solutions without jquery and they also fail for firefox.

so i'm open to any result that works consistently (jquery or not). thanks in advance.

• What does keyevent_cb do? Is there the suggestion of any errors therein? – David Thomas Commented Dec 14, 2011 at 19:29
• it's just a call back function. prints an alert box. – ct_ Commented Dec 14, 2011 at 19:32
• Do you want to fire the callback on all keypress events or only under certain conditions? – Phil Klein Commented Dec 14, 2011 at 19:39
• all key presses and subsequent. – ct_ Commented Dec 14, 2011 at 20:06

The following attaches a keypress event listener to the body element:

$("body").on("keypress", function (e) {
    // logic for key event here
});

With your keyevent_cb callback, you could simply do:

$("body").on("keypress", keyevent_cb);

$(document).keypress(function(e)
{
    switch(e.which)
    {
        // user presses the "a"
        case 97: doSomething(); break;
    }
});
