[转] js对键盘输入事件绑定到特定按钮。

<script type="text/javascript" language="javascript">
        document.onkeyup = function (event) {
            var e = event || window.event;
            var keyCode = e.keyCode || e.which;
            switch (keyCode) {
                case :
                    $("#btnPrint").click();
                    break;
                case :
                    $("#btnUpload").click();
                    break;
                default:
                    break;
            }
        }
</script>

在Web开发中，有时候我们可能会把页面中的某些按钮绑定到键盘的输入事件中。以上代码能方便实现我们需要的功能。

以下为键盘的所有keyCode  :

使用event对象的keyCode属性判断输入的键值
 eg：if(event.keyCode==)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　 　　 0X48
H　　0X72　 　　 0X49
I 　　0X73　 　　 0X50
J 　　0X74　  　　0X51
K　　0X75　  　　0X52
L　　0X76　  　　0X53
M　　0X77　 　　 0X54
N　　0X78 　 　　0X55
O　　0X79 　 　　0X56
P　　0X80 　 　　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
