解决方案

检查ctrl + a，ctrl + A，ctrl + c，ctrl + C，ctrl + u，ctrl + U下面的代码。 pre> < script type =text / javascript>
var isNS =（navigator.appName ==Netscape）？ 1：0;

if（navigator.appName ==Netscape）document.captureEvents（Event.MOUSEDOWN || Event.MOUSEUP）;

函数mischandler（）{
return false;
}

函数mousehandler（e）{
var myevent =（isNS）？ e：事件;
var eventbutton =（isNS）？ myevent.which：myevent.button;
if（（eventbutton == 2）||（eventbutton == 3））return false;
}
document.oncontextmenu = mischandler;
document.onmousedown = mousehandler;
document.onmouseup = mousehandler;
var isCtrl = false;
document.onkeyup = function（e）
{
if（e.which == 17）
isCtrl = false;


document.onkeydown = function（e）
{
if（e.which == 17）
isCtrl = true;如果（（（其中== 95）||（e.which == 117）||（e.which == 65）||（例如== 97）||（e。其中== 67）||（e.which == 99））&& isCtrl == true）
{
// alert（'Keyboard shortcuts are cool！'）;
返回false;
}
}

if(navigator.appName == "Netscape") document.captureEvents(Event.MOUSEDOWN||Event.MOUSEUP);

function mischandler(){
return false;
}

function mousehandler(e){
var myevent = (isNS) ? e : event;
var eventbutton = (isNS) ? myevent.which : myevent.button;
if((eventbutton==2)||(eventbutton==3)) return false;
}
document.oncontextmenu = mischandler;
document.onmousedown = mousehandler;
document.onmouseup = mousehandler;
var isCtrl = false;
document.onkeyup=function(e)
{
if(e.which == 17)
isCtrl=false;
}

document.onkeydown=function(e)
{
if(e.which == 17)
isCtrl=true;
if(((e.which == 85) || (e.which == 117) || (e.which == 65) || (e.which == 97) || (e.which == 67) || (e.which == 99)) && isCtrl == true)
