$("#text").bind('keypress', function(e) {
var code = (e.KeyCode ? e.keyCode : e.which);
alert(code);
}
It works fine for everything except Alt, Ctrl, or Shift.
But in all tutorials that i found it should echos 17, 18, 19
Why?

Reset to default 4use .keydown() or .keyup()
see it in action
jQuery(function($){
var output = $('.output');
$("#text1").bind('keypress', function(e) {
var code = (e.KeyCode ? e.keyCode : e.which);
output.text(code);
});
$("#text2").bind('keydown', function(e) {
var code = (e.KeyCode ? e.keyCode : e.which);
output.text(code);
});
$("#text3").bind('keyup', function(e) {
var code = (e.KeyCode ? e.keyCode : e.which);
output.text(code);
});
})<script src="https://ajax.googleapis./ajax/libs/jquery/1.4.2/jquery.min.js"></script>
keypress <input type="text" id="text1"> <br>
keydown <input type="text" id="text2"> <br>
keyup <input type="text" id="text3">
<br><br>
Output: <span class="output"></span>Have you considered using the jquery.hotkeys extension that allows you to bind by specifying a string?
"C-A-q" would bind you to:
Control + Alt + q.
It would probably be better to use console.log to find them. You can also use just one textbox easily for this.
$("#textbox").keydown(function(e) {
console.log("keydown: "+e.keyCode);
});
And do the same for keyup and keypress to see better how it all works.
Side note: JavaScript sure is hard to write on a phone ;)
