Detect multiple keys on single keypress event in jQuery
javascript, jquery, jquery-events, keypress
Solution
If you want to detect that the d, e, and v keys were all down at the same time, you have to watch both `keydown` and `keyup` and keep a map of the ones that are down. When they're all down, fire your event.
For example: Live copy | source
var map = {68: false, 69: false, 86: false};
$(document).keydown(function(e) {
if (e.keyCode in map) {
map[e.keyCode] = true;
if (map[68] && map[69] && map[86]) {
// FIRE EVENT
}
}
}).keyup(function(e) {
if (e.keyCode in map) {
map[e.keyCode] = false;
}
});
I assume you don't care what order they're pressed down in (as that would be a pain to reliably press) as long as they're all down at the same time at some point.
Problem
Is it at all possible to combine a mixture of keypress' to fire a single event? ``` $(document).keyup(function(e){ if (e.keyCode == 68 && e.keyCode == 69 && e.keyCode == 86) { alert('oh hai'); } }); ``` I've tried it in Chrome but the event doesn't fire. Call me crazy but I am writing a Chrome extension and want to push D+E+V keys together to force it into a hidden developer mode.
