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;
