使用  
<script language="javascript">  
     function keyevent()\{  
     if(event.keyCode==13)  
     alert("\#$%\#%\#^^%");  
     \}  
     document.onkeydown = keyevent;  
< /script>  
event.keyCode值為37﹐38﹐39﹐40對應按下的方向鍵分別是 左﹐上﹐右﹐下  
  
  
  
"javascript:if (event.keyCode < 45 || event.keyCode > 57) event.returnValue = false;");  
  
  
  
if(event.keycode==13)就代表按下的是回车键盘  
  
  
"javascript:if (event.keyCode > 45 && event.keyCode < 57) event.returnValue = false;");

使用javascript在WEB页面中截获键盘输入  
使用event对象的keyCode属性判断输入的键值  
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  
N　　0X78 　7 　　0X55  
O　　0X79 　8 　　0X56  
P　　0X80 　9 　　0X57  
Q　　0X81　ESC　　0X1B  
R　　0X82　CTRL 　0X11  
S　　0X83　SHIFT　0X10  
T　　0X84　ENTER　0XD  
  
如果要使用组合键，则可以利用event.ctrlKey，event.shiftKey，event .altKey判断是否按下了ctrl键、shift键以及alt键
