禁止页面内容被拷贝的又一法

在你的body里加入下面的代码，再加上去掉工具栏，菜单，别人就很难拷贝你页面上的文字了！！
<body
onmousemove="document.selection.empty();"
onmouseup="document.selection.empty();"
oncopy="document.selection.empty();"
onselect="document.selection.empty();"
oncontextmenu="return false;">
onmousemove="document.selection.empty();"
onmouseup="document.selection.empty();"
oncopy="document.selection.empty();"
onselect="document.selection.empty();"
oncontextmenu="return false;">
