1、全局在body上设置属性:
<body on selectstart="return false" on paste="return false" on copy="return false" on cut="return false">
2、js控制页面无法复制：
<script type="text/ja vascript">
//Method one
//<![CDATA[
//document.on contextmenu=new Function('event.returnValue=false;');
document.on contextmenu = function (e) { e = e || window.event; e.returnValue = false; }
document.on selectstart = new Function('event.returnValue=false;');
//]]>
</script>
<!--Method two-->
<body on contextmenu="return false" on selectstart="return false"></body>
3、css 控制页面无法复制：
-moz-user-select: none; -webkit-user-select: none; -ms-user-select: none; -khtml-user-select: none; user-select: none;
