如何将HTML表导出为.xlsx文件

更新时间:2023-01-31 18:56:09

如果不返回服务器,将无法将其导出为XLSX. XLSX文件是压缩在一起的XML文件的集合.这意味着您确实需要创建多个文件.使用客户端JS不可能做到这一点.

相反,您应该创建一个函数来从HTML表中检索数据并将其发送到服务器.然后,服务器可以为您创建XLSX文件(有大量可用的库!),然后将其发送回客户端进行下载.

如果您希望拥有庞大的数据集,则应在服务器上创建XLSX作为一个异步过程,在异步过程中,您将在完成时通知用户(而不是让用户等待文件的创建). /p>

让我们知道您在服务器上使用哪种语言,我们将向您推荐一些优质的库.

I have a question about exporting an HTML table as an xlsx file. I did some work and now I can export it as an xls, but I need to export it as an xlsx.

Here is my jsFiddle: https://jsfiddle.net/272406sv/1/

Here is my HTML:

<table id="toExcel" class="uitable">
  <thead>
    <tr>
      <th>Kampanya Basligi</th>
      <th>Kampanya Türü</th>
      <th>Kampanya Baslangiç</th>
      <th>Kampanya Bitis</th>
      <th style="text-align: center">Aksiyonlar</th>
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="Item in campaign.campaignList">
      <td> Item.CampaignTitle </td>
      <td> Item.CampaignHotelType </td>
      <td> Item.CampaignHotelCheckInDate) </td>
      <td>Item.CampaignHotelCheckOutDate</td>
      <td style="text-align: center">
        <button> Some Action </button>
      </td>
    </tr>
  </tbody>
</table>

<button onclick="exceller()">EXCEL</button>

Here is my JavaScript code:

<script>
  function exceller() {
    var uri = 'data:application/vnd.ms-excel;base64,',
      template = '<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"><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><body><table>{table}</table></body></html>',
      base64 = function(s) {
        return window.btoa(unescape(encodeURIComponent(s)))
      },
      format = function(s, c) {
        return s.replace(/{(\w+)}/g, function(m, p) {
          return c[p];
        })
      }
    var toExcel = document.getElementById("toExcel").innerHTML;
    var ctx = {
      worksheet: name || '',
      table: toExcel
    };
    var link = document.createElement("a");
    link.download = "export.xls";
    link.href = uri + base64(format(template, ctx))
    link.click();
  }
</script>

You won't be able to export it as XLSX without going back to the server. A XLSX file is a collection of XML files, zipped together. This means you do need to create multiple files. This is impossible to do with JS, client-side.

Instead, you should create a function retrieving the data from your HTML table and send that to you server. The server can then create the XLSX file for you (there are a bunch of libs available for that!) and send it back to the client for download.

If you expect to have a huge dataset, the XLSX creation on the server should be done as an async process, where you notify the user when it's done (instead of having the user waiting for the file to be created).

Let us know which language you use on your server, and we'll be able to recommend you some good libraries.
