JS实现复制网页内容自动加入版权内容代码和原文链接

实现代码：在body内放入如下代码即可：

<script type="text/javascript">
var Sys = {};
var ua = navigator.userAgent.toLowerCase();
if( window.ActiveXObject ){
    document.body.oncopy = function(){
        event.returnValue = false;
        var t=document.selection.createRange().text;
        var s=" 原文链接："+location.href;
        clipboardData.setData('Text',t+'\r\n'+s);
    };
}else{
    function addLink(){
        var body_element = document.getElementsByTagName('body')[0];
        var selection;
        selection = window.getSelection();
        var pagelink = " 原文链接："+location.href;
        var copytext = selection + pagelink;
        var newdiv = document.createElement('div');
        newdiv.style.position='absolute';
        newdiv.style.left='-99999px';
        body_element.appendChild(newdiv);
        newdiv.innerHTML = copytext;
        selection.selectAllChildren(newdiv);
        window.setTimeout(function(){body_element.removeChild(newdiv);},0);
    }
    document.oncopy = addLink;
}
</script>
