使用event对象的keyCode属性判断输入的键值155
eg：if(event.keyCode==13)alert(“enter!”);156
键值对应表157
A 0X65 U 0X85158
B 0X66 V 0X86159
C 0X67 W 0X87160
D 0X68 X 0X88161

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
例如：用回车模拟Tab:
<input type="text" name="textfield" onkeydown="if(event.keyCode==13)event.keyCode='9'">
<input type="text" name="textfield2">
