 //Disable right button, text selection function, copy button  
    $(document).bind("contextmenu",function(){return false;});  
    $(document).bind(" select start",function(){return false ;});  
    $(document).keydown(function(){return key(arguments[0])});       //Prompt warning when pressing key       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("No copying!");       return false ;       }       }       //Disable right button, text selection function, copy button           $(document).bind("contextmenu",function(){return false;});
