如何将HTML表导出为.xlsx文件 [英] How to export an HTML table as a .xlsx file
问题描述
我对将 HTML表导出为 xlsx 文件有疑问.我做了一些工作，现在可以将其导出为 xls ，但是我需要将其导出为 xlsx .
这是我的jsFiddle:: https://jsfiddle.net/272406sv/1/
这是我的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>
这是我的JavaScript代码:
<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>
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>

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 Baslangiç</th>
<th>Kampanya Bitis</th>
<th style="text-align: center">Aksiyonlar</th>

<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,',

base64 = function(s) {
return window.btoa(unescape(encodeURIComponent(s)))

format = function(s, c) {

}
var toExcel = document.getElementById("toExcel").innerHTML;
var ctx = {

var link = document.createElement("a");
link.download = "export.xls";

</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.
