如何导出到xls文件正在流星？

Question

我有一个对象。单击按钮时，对象存储在变量中。在同样的点击功能，我需要将该对象导出到Meteor中的xls（excel）文件。有帮助吗？

   html page
  <button class="export-data btn btn-success" type="submit" >Export Data</button>

 JavaScript file, client side
Template.ExportActivationCodes.events({
"click .export-data": function (event, template) {
    var advertiserdatas = template.find("#exportId").value;
    var nameFile = 'fileDownloaded.csv';
    Meteor.call('download',advertiserdatas, function(err, fileContent)    {
        if (fileContent) {
            var blob = new Blob([fileContent], {type: "text/plain;charset=utf-8"});
            saveAs(blob, nameFile);
        }
    });
   }
  });


 Meteor methods server side

 download: function(advertiserdatas) {
    var collection = ActivationCodes.find({advertiserId:parseInt(advertiserdatas)}).fetch();
    var heading = true; // Optional, defaults to true
    var delimiter = ";" // Optional, defaults to ",";

    return exportcsv.exportToCSV(collection, heading, delimiter);
}
