今天完成的事情：

静态页面的书写，js键盘事件

js中获取键盘事件

  <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。

151 键值对应表

152 A　　0X65 　U 　　0X85

153 B　　0X66　 V　　 0X86

154 C　　0X67　 W　　 0X87

155 D　　0X68　 X 　　0X88

156 E　　0X69　 Y　　 0X89

157 F　　0X70　 Z　　 0X90

158 G　　0X71　 0　　 0X48

159 H　　0X72　 1　　 0X49

160 I　　0X73　 2　　 0X50

161 J　　0X74　 3 　　0X51

172 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
