자바스크립트 단축키 사용 [Key Binding]
Scripter/JAVASCRIPT 2008/08/19 10:20가끔씩 Ajax 웹어플리케이션을 만들다 보면 단축키를 요구하는 고객들이 많다.
그러한 이유로 단축키 관련 스크립트를 찾아보던중에 prototype el.observe() (extjs에서는 el.on())를 이용한 keycode를 바인딩해주는
스크립트를 찾았다.
얼마전에 ajaxian post에 올라왔던 글이였는데 잊고 있었던거.. ㅡ.,ㅡ;
잠시 꼬불쳐 두다... 키값 참조할때도 좋겠다.

**************************************
F5키를 막는 방법은 아래와 같습니다.
마우스 오른쪽 클릭으로 새로고침하는 것을 방지
* 메뉴와 도구모음에서 새로고침하는 것은 원천적으로는 막을 수 없습니다. (물론 없애버릴 수는 있다지만...)
