javascript 实现禁止右键，复制，选取文本 (兼容firefox，IE，chrome等主流浏览器)

1. JS 禁止右键

<script type="text/javascript">document.oncontextmenu=function(e){return false;}</script>

<body onselectstart="return false">

......

2. CSS 禁止复制和选取

如果让整个页面都禁止选择　　

<style type="text/css">

body {

    -webkit-touch-callout: none;

    -webkit-user-select: none;

    -khtml-user-select: none;

    -moz-user-select: none;

    -ms-user-select: none;

    user-select: none;　　

}

</style>

如果是局部

Html代码

<style type="text/css">

.unselectable {

   -moz-user-select: -moz-none;

   -khtml-user-select: none;

   -webkit-user-select: none;

   /*

     Introduced in IE 10.

     See http://ie.microsoft.com/testdrive/HTML5/msUserSelect/

   */

   -ms-user-select: none;

   user-select: none;

}

</style>

3. 完整实例：

<style type="text/css">

body {

    -webkit-touch-callout: none;

    -webkit-user-select: none;

    -khtml-user-select: none;

    -moz-user-select: none;

    -ms-user-select: none;

    user-select: none;

}

</style>

<script langauge="javascript">

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

</script>

</head>  

<body onselectstart="return false">

... ...
