I'm having a problem similar to http://stackoverflow.com/questions/2721970/jquery-ajax-not-working-in-ie8-but-it-works-on-firefox-chrome, but with a different use case.
I'm using the jQuery Form plug-in to handle a file upload to an ASP.NET MVC controller, which sends the file off for parsing and processing. If an Exception is thrown, it should alert the user to the issue.
//client side code
//make an ajax call, sending the contents of the file
$("#ajaxUploadForm").ajaxSubmit({
dataType: 'json',
url: '/plan/Something/ExcelImport',
iframe: true,
beforeSend: function () {
$(".ui-dialog-buttonpane").find("#my_progress").fadeIn();
},
success: function (data, textStatus) {
output = "<center><span class='flash'>" + data.message + "</span></center>";
$("#flash_message").html(output).fadeIn('slow');
setTimeout(function () { $("#flash_message").fadeOut() }, 5000);
cleanup();
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("XMLHttpRequest is " + XMLHttpRequest);
var contents = "";
for (prop in XMLHttpRequest) {
contents += "\na property is " + prop + " it's value is " + XMLHttpRequest[prop];
}
alert("the contents are " + contents);
alert("textStatus is " + textStatus);
alert("errorThrown is " + errorThrown);
//comes back in an HTML envelope. This should be parsed with regex, but I can't get it to work. Dirty hack
response = XMLHttpRequest.responseText.substring(XMLHttpRequest.responseText.indexOf("<body>"));
response = response.replace("<body>", "");
response = response.replace("</body>", "");
alert("There was a problem with the upload.\r\n" + response);
},
complete: function (XMLHttpRequest, textStatus) {
$(".ui-dialog-buttonpane").find("#my_progress").remove();
something_import.dialog('close');
something_import.dialog('destroy');
}
});
//server side code
public FileUploadJsonResult ExcelImport()
{
FileUploadJsonResult result = new FileUploadJsonResult();
HttpPostedFileBase hpf = Request.Files[0] as HttpPostedFileBase;
if (hpf.ContentLength == 0)
return new FileUploadJsonResult { Data = new { message = "File contained no data" } };
String fileName = Path.GetFileName(hpf.FileName);
String timeStampedFile = fileName.Insert(fileName.IndexOf('.'),"_"+DateTime.Now.ToFileTimeUtc());
string savedFileName = Path.Combine(AppDomain.CurrentDomain.BaseDirectory + "tempo", timeStampedFile);
hpf.SaveAs(savedFileName);
try
{
result = ProcessFile(savedFileName, Request["Id"]) as FileUploadJsonResult;
}
catch (ArgumentException e)
{
this.Response.StatusCode = 500;
this.Response.StatusDescription = System.Net.HttpStatusCode.BadRequest.ToString();
Response.Write(e.Message);
result = Json(new { message = e.Message, stackTrace = e.StackTrace }) as FileUploadJsonResult;
}
return result;
}
This works perfectly in Chrome and Firefox. In IE, the XMLHttpRequest object coming back is different:
FF:
IE:
I've been Googling around for differences between the browser implementations of XMLHttpRequest, but haven't found anything that deals specifically with this case. Stymied.
