如果模型对话框已打开，则无法下载文件

Question

We opened an popup by using jquery extension.Our requirement is to download a file on click of button present in popup. My code is like this:-

JS code:-
showModalData: function (obj) {
        var url = OC.MVC.util.getLink("Employee", "GetDetail");
        $.ajax({
            url: url,
            type: 'GET',
            success: function (result) {                         
                $.modal(result);//open the modal popup
            },
            error: function (err) {
                alert(err.responseText);
            }
        });
    }

Controller code:-
 public virtual ActionResult GetDetail(Employee model)
        {
            return PartialView(model);
        }

View:-
<div>
@Html.Raw(Html.Button("btnDownload", "Download").ToString())
<div>

Now on click of Download I have to download the file for this code is:-

  public ActionResult Download()
        {
            byte[] fileBytes = System.IO.File.ReadAllBytes(@"c:\New\note.txt");
            string fileName = "note.txt";
            return (File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, fileName));

        }

On click of download button it will call the Download action defined in controller.Now return (File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, fileName)); should opens the save dialog to select the path to save the document.But it is not opening the save dialog box.It is also not showing error and nothing is happening.Note: Download button present in Modal Popup.

您需要确保您的下载操作是通过来自浏览器的正常 HTTP 请求调用的，而不是通过 JavaScript 发起的 AJAX 调用调用的。
