屏蔽鼠标右键:
function document.oncontextmenu(){event.returnValue=false;}

屏蔽F1帮助:
function window.onhelp(){return false}

屏蔽其他键
function document.onkeydown()
{
   if ((window.event.altKey)&&
   ((window.event.keyCode==37)|| //屏蔽 Alt+ 方向键 ←
   (window.event.keyCode==39))) //屏蔽 Alt+ 方向键 →
   {
    alert("不准你使用ALT+方向键前进或后退网页!");
    event.returnValue=false;
   }
   
   if ((event.keyCode==8)   ||                 //屏蔽退格删除键
   (event.keyCode==116)||                 //屏蔽 F5 刷新键
   (event.ctrlKey && event.keyCode==82)){ //Ctrl + R
    event.keyCode=0;
    event.returnValue=false;
    }
   if (event.keyCode==122){event.keyCode=0;event.returnValue=false;}   //屏蔽F11
   if (event.ctrlKey && event.keyCode==78) event.returnValue=false; //屏蔽 Ctrl+n
   if (event.shiftKey && event.keyCode==121)event.returnValue=false;   //屏蔽 shift+F10
   if (window.event.srcElement.tagName == "A" && window.event.shiftKey)  
   window.event.returnValue = false;          //屏蔽 shift 加鼠标左键新开一网页
   if ((window.event.altKey)&&(window.event.keyCode==115))          //屏蔽Alt+F4
   {
   window.showModelessDialog("about:blank","","dialogWidth:1px;dialogheight:1px");
   return false;
   }
}

屏蔽打印:
<style>
@media print{
* {display:none}
}
</style>
