代碼如下:
//禁用右鍵、文本選擇功能、復制按鍵
$(document).bind("contextmenu",function(){return false;});
$(document).bind("selectstart",function(){return false;});
$(document).keydown(function(){return key(arguments[0])});
//按鍵時提示警告
function key(e){
var keynum;
if(window.event){
keynum = e.keyCode; // IE
}else if(e.which){
keynum = e.which; // Netscape/Firefox/Opera
}
if(keynum == 17){
alert("禁止復制內容!");
return false;
}
}
//禁用右鍵、文本選擇功能、復制按鍵
$(document).bind("contextmenu",function(){return false;});
$(document).bind("selectstart",function(){return false;});
$(document).keydown(function(){return key(arguments[0])});
//按鍵時提示警告
function key(e){
var keynum;
if(window.event) // IE
{
keynum = e.keyCode;
}
else if(e.which) // Netscape/Firefox/Opera
{
keynum = e.which;
}
if(keynum == 17){ alert("禁止復制內容!");return false;}
}
//屏蔽鼠標右鍵、Ctrl+N、Shift+F10、F11、F5刷新、退格鍵

event.returnValue=false;
} if((event.keyCode==8)|| //屏蔽退格刪除鍵

}
