javascript implements the method that the client side is compatible with each browser to create csv and download

The example in this article shows how to implement javascript to create and download csv compatible with all browsers. Share with you for your reference. The specific implementation method is as follows:

$("#radarDLBut").click(function(){
var data = [displayData["radar_chart"]["r_label"],displayData["radar_chart"]["r_default"]]; 
var csvContent = "data:text/csv;charset=utf-8,\ufeff";
if (window.navigator.msSaveOrOpenBlob) {
  csvContent = "\ufeff";
}
data.forEach(function(infoArray, index){
  dataString = infoArray.join(",");
  csvContent += index < data.length ? dataString+ "\n" : dataString;
});
if (window.navigator.msSaveOrOpenBlob) {
  // if browser is IE
  var blob = new Blob([decodeURIComponent(encodeURI(csvContent))],{
 type: "text/csv;charset=utf-8;"
  });
  navigator.msSaveBlob(blob, 'subject.csv');
}else{
  var encodedUri = encodeURI(csvContent);
  var link = document.createElement("a");
  link.setAttribute("href", encodedUri);
  link.setAttribute("download", "subject.csv");
  document.body.appendChild(link);
  link.click();
}
});
