html中table导出Excel

有时候我们需要把网页中的数据导出excel格式来，那么我们用下面两种方法可以完成。

第一种.自写代码

<html>
<head>
<meta http-equiv="content-Type" content="text/html;charset=utf-8"/>
<script type="text/javascript">
    function base64 (content) {
       return window.btoa(unescape(encodeURIComponent(content)));         
    }
    /*
    *@tableId: table的Id
    *@fileName: 要生成excel文件的名字（不包括后缀，可随意填写）
    */
    function tableToExcel(tableID,fileName){
        var table = document.getElementById(tableID);
      var excelContent = table.innerHTML;
      var excelFile = "<html xmlns:o='urn:schemas-microsoft-com:office:office' xmlns:x='urn:schemas-microsoft-com:office:excel' xmlns='http://www.w3.org/TR/REC-html40'>";
      excelFile += "<head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head>";
      excelFile += "<body><table>";
      excelFile += excelContent;
      excelFile += "</table></body>";
      excelFile += "</html>";
      var link = "data:application/vnd.ms-excel;base64," + base64(excelFile);
      var a = document.createElement("a");
      a.download = fileName+".xlsx";
      a.href = link;
      a.click();
    }
</script>
</head>
<body>
<button type="button" onclick="tableToExcel('item','data')">导出</button>
<table id="item">
  <tr>
    <th>编号</th>
    <th>姓名</th>
    <th>年龄</th>
  </tr>
  <tr>
    <td>1</td>
    <td>小明</td>
    <td>19</td>
  </tr>
  <tr>
    <td>2</td>
    <td>小芳</td>
    <td>20</td>
  </tr>
  <tr>
    <td>3</td>
    <td>大军</td>
    <td>22</td>
  </tr>
</table>
</body>
</html>

第二种.jquery插件

首先要先下载一个jquery.table2excel.js插件(网上搜搜)，然后使用。
