1、锁定右键

< body oncontextmenu = "return false" ondragstart = "return false" onselectstart = "return false" onselect = "document.selection.empty()" oncopy = "document.selection.empty()" onbeforecopy = "return false" onmouseup = "document.selection.empty()" >

2.拒绝另存

<noscript> <iframe src="/*>" ;</iframe> </noscript>

3.不准粘贴

οnpaste= "return false" 

4.防止复制

οncοpy= "return false;" oncut="return false;"

5.关闭输入法

< input style = "ime-mode:disabled" >

6.JS 屏蔽鼠标右键

/** 屏蔽鼠标右键 */  

document.oncontextmenu = function(){ return false ;} 

//或者 

document.onmousedown = function(event){ 

      event = window.event || event;

      if (document.all && event.button == 2 ) {

            event.returnvalue= false ; 

       } 

 }
