键盘按钮keyCode大全

<script type="text/javascript" language=JavaScript charset="UTF-8">
      document.onkeydown=function(event){
            var e = event || window.event || arguments.callee.caller.arguments[0];
            if(e && e.keyCode==27){ // 按 Esc 
                //要做的事情
              }
            if(e && e.keyCode==113){ // 按 F2 
                 //要做的事情
               }            
             if(e && e.keyCode==13){ // enter 键
                 //要做的事情
            }
        }; 
</script>
只要你定义了这些键的动作，你在浏览器里按下这些键就会响应，兼容目前所有浏览器。

eg：if(event.keyCode==13)alert(“enter!”);
键值对应表
A　　0X65 　U 　　0X85
B　　0X66　 V　　 0X86
C　　0X67　 W　　 0X87
D　　0X68　 X 　　0X88
E　　0X69　 Y　　 0X89
F　　0X70　 Z　　 0X90
G　　0X71　 0　　 0X48
H　　0X72　 1　　 0X49
I　　0X73　 2　　 0X50
J　　0X74　 3 　　0X51
K　　0X75　 4 　　0X52
L　　0X76　 5 　　0X53
M　　0X77　 6　　 0X54

Q　　0X81　ESC　　0X1B
R　　0X82　CTRL 　0X11
S　　0X83　SHIFT　0X10
T　　0X84　ENTER　0XD
如果要使用组合键，则可以判断是否同时按下了这几个键，比如ctrl键、shift键以及alt键的组合使用就可以判断是否多按下了ctrl键、shift键以及alt键
