二、检测同时按下的控制键用：
event.altKey true为按下了Alt键
event.ctrlKey true为按下了Ctrl键
event.shiftKey true为按下了Shift键
三、判断函数
//是否数字键
function isnumkey(nkey)
{
if(!event.altKey && !event.ctrlKey && !event.shiftKey &&
(nkey>=48 && nkey<=57 || nkey>=96 && nkey<=105))
return true;
else
return false;
}
//是否字母键
function isalphakey(nkey)
{
if(!event.altKey && !event.ctrlKey && nkey>=65 && nkey<=90)
return true;
else
return false;
}
//是否字符键
function ischarkey(nkey)
{
if(!event.altKey && !event.ctrlKey && (nkey>=65 && nkey<=90 ||
nkey>=48 && nkey<=57 || nkey>=96 && nkey<=105 || nkey==106 ||
nkey==107 || nkey==109 || nkey==110 || nkey==111 ||
nkey>=186 && nkey<=192 || nkey>=219 && nkey<=222))
return true;
else
return false;
}
