java代码导出数据到Excel、js导出数据到Excel(三)

jsp内容忽略，仅写个出发按钮：

         <button style="width: 100px" onclick="expertExcel()" >JS导出Excel</button>   
        <button style="width: 100px" onclick="expertWord()" >JS导出Word</button>   
        <button style="width: 100px" onclick="getDataToExcel2()" >代码导出</button>

      <div class ='main' id='main'></div>
      <div class ='bottom' id='buttom12'>
      </div>

    </div>
</body>
</html>
<script type="text/javascript">

//后台弹出框式导出数据到Excel
  function getDataToExcel2(){
   var sssj = document.getElementById("time_ctrol").value;
   var xtmc = document.getElementById("st").value;

   xtmc = encodeURI(encodeURI(xtmc));
   var requestURL = "./DataToExcel.jsp?type=getDataToExcel&sssj=" + sssj + "&xtmc=" + xtmc;
   window.open(requestURL);
  }

  function createXMLHttpRequest(){
     if (window.ActiveXObject) {
    XMLhttpObject = new ActiveXObject("Microsoft.XMLHTTP");
   } else {
    XMLhttpObject = new XMLHttpRequest();
   }
     return XMLhttpObject;
  }

</script>

//js导出EXCEL
<script type="text/javascript">
   function expertExcel(){
    var oXL = new ActiveXObject("Excel.Application");
      var oWB = oXL.Workbooks.Add();
      var oSheet = oWB.ActiveSheet;
      var sel=document.body.createTextRange();
      sel.moveToElementText(main);
      sel.select();
      sel.execCommand("Copy");
      oSheet.Paste();
      oXL.Visible = true;
   }

代码导出页面，抄袭来自csdn：

    //response.setHeader("Content-Disposition", "attachment;filename= aa.xls");
