I have this event handler that does downloading and that's working great on all browsers except IE, so I handled it with msSaveBlob
and it download file, but when I open it, it said format isn't good, so my guess is that I don't use valid data in blob.
$(document).on('click', '.register-file-uploader-download-file', function () {
let $fileResultsItem = $(this).closest('.form-fields__file-results-item');
const fileName = $fileResultsItem.find('.multiple-files-upload-item').data('filename');
const fileUrl = $fileResultsItem.find('.multiple-files-upload-item').val();
if (fileUrl.length > 0) {
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
if (this.readyState === 4 && this.status === 200) {
var url = window.URL || window.webkitURL;
let blobFileUrl = url.createObjectURL(this.response);
if (window.navigator && navigator.msSaveBlob) { // For IE
const blobObj = new Blob([this.response], { type: 'application/octet-stream' });
return navigator.msSaveBlob(blobObj, fileName);
}
const a = document.createElement('a');
a.style.display = 'none';
a.href = blobFileUrl;
a.download = `${fileName}`;
document.body.appendChild(a);
a.click();
url.revokeObjectURL(blobFileUrl);
}
};
xhr.open('GET', fileUrl);
xhr.responseType = 'blob';
xhr.send();
}
});
