<SCRIPT>function copyCode(o){o.select();var js=o.createTextRange();js.execCommand("Copy");alert("复制成功！");}document.write("<table align=center cellpadding=1 cellspacing=0><tr>");document.write("<td width=10% nowrap>本文地址(双击可复制):</td>");document.write("<td><textarea onfocus=this.select() style='width:99%;overflow-y:visible;' ondblclick=copyCode(this) rows=1>");document.write(self.location+"</textarea></td></tr></table>");</SCRIPT>

效果二：纯按键

  <Input onclick=copyToClipBoard() type=button value=【立即推荐您的好友阅读】>
<SCRIPT language=javascript>
   function copyToClipBoard(){
    var clipBoardContent="";
    clipBoardContent+=document.title;
    clipBoardContent+="\n";
    clipBoardContent+=this.location.href;
    window.clipboardData.setData("Text",clipBoardContent);
    alert("复制成功");
  }
  </SCRIPT>
 </INPUT>

上面为两种效果，可以根据需要修改！
