There is a problem in some browsers, for example, Firefox.
Code:
$(document).ready(function(){
$(this).keydown(function(e){ // Or keyup or keypress
alert(***look at output***);
}
}
when typing non-latin characters as "<"-"б"-"Б" (russian) shows:
keydown keyCode=0 which=0 charCode=0
keypress keyCode=0 which=1073 charCode=1073 char=б
keyup keyCode=0 which=0 charCode=0
the same character in Chrome shows:
keydown keyCode=188 which=188 charCode=0
keypress keyCode=1073 which=1073 charCode=1073 char=б
keyup keyCode=188 which=188 charCode=0
Problem: Identify keydown handler in all browsers, without using keypress (because of different charCodes on different keyboards layouts).
Solved, but with keypress. By listening keypress handle special for firefox bug, when with cyrillic keyboard layout doesn't work "<",">".
Solution: on pressing keyboard button we listen keydown and keypress handels at the same time. If the cyrillic character pressed firefox keyCode output is 0 and keydown ignore it. On the other hand, keypress takes keyCode == 0 and makes an output "<" or ">".
