不太好做啊....下面的代码效果不太好:
<div oncontextmenu="return false" onselectstart ="return false" onselect="document.selection.empty()" oncopy="document.selection.empty()" onbeforecopy="return false" >
这些文字被保护了
</div>
<div>
这些文字可以COPY
</div>
<div oncontextmenu="return false" onselectstart ="return false" onselect="document.selection.empty()" oncopy="document.selection.empty()" onbeforecopy="return false" >
这些文字被保护了
</div>
<div>
这些文字可以COPY
</div>
