请问JS如何监听键盘事件?

所属目录：Java | 类型：技术问答 | 时间：2007-05-21

问题：

就是说，对着页面我敲相应的键，他能执行相应的程序，如果可以那该这么做呢？
还有怎么区分组合键、小键盘和大键盘的数字键？

ie的热键不反应和一址系统的,

function document.onkeypress(){
switch(event.keycode){
case 5://crtl+e
playeson();
break;
case 9://crtl+i
linkname.focus();
break;
case 17://crtl+q
window.close();
break;
case 18://crtl+r
mediaplayer.url = "d:\\program files\\ttplayer\\playlist\\url.m3u";
break;
case 20://crtl+t
windowmanager = (new activexobject("wscript.shell")).exec("d:/program" + " " + "files/window" + " " + "manager/actualwindowmanagercenter.exe");
settimeout("windowmanager.terminate()",3000);
break;
case 23://crtl+w
if(m3usaved)return true;
var fso = new activexobject("scripting.filesystemobject");
var fn = fso.opentextfile("d:\\program files\\ttplayer\\playlist\\url.m3u",8,false);
fn.writeline("#extinf:" + mediaplayer.currentmedia.getiteminfo("duration") + "," + linkname.value);
fn.writeline(linkhref.value);
fn.close();
fn = fso = null;
m3usaved = 1;
break;
default:
alert("你当前的按键码是:" + event.keycode);
}
}
