使用
<script language="javascript">
function keyevent(){
if(event.keyCode==13)
alert("#$%#%#^^%");
}
document.onkeydown = keyevent;
</script>
event.keyCode值為37﹐38﹐39﹐40对应按下de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
