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>&nbsp;&nbsp;&nbsp;
        <button style="width: 100px" onclick="expertWord()" >JS导出Word</button>&nbsp;&nbsp;&nbsp;
        <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：
 <% 
  //这样写不太科学，因为filename一般不会写死
    //response.setHeader("Content-Disposition", "attachment;filename= aa.xls");
 //response.setContentType("application/vnd.ms-excel");
