Valums文件上传器在Internet Explorer 9下不起作用

Valums file-uploader(现在称为Fine Uploader)在Internet Explorer 9下不起作用,但在Chrome下也不错。

因此,在IE下,它显示文件的名称和按钮CANCEL,并且没有上传的百分比。

有任何线索吗?

我知道这个问题是专门在asp.net下提出的,但是当我搜索“valums ajax upload IE9”时,它就出现了,所以我会在这里发布我的修复,以防它像我一样帮助任何人,无论语言如何: / p>

我从AJAX上传请求返回一个带有“application / json”内容标头的JSON响应。 IE9不知道如何处理“application / json”内容(但Chrome / FF /等)。

我通过确保从服务器返回我的json响应中的“ text / html ”MIME类型http标头来修复此问题。

现在IE不再尝试下载响应了!干杯

我无法重现此问题。这是一个完整的工作示例。

控制器:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Upload(HttpPostedFileBase qqfile)
    {
        var uploadPath = Server.MapPath("~/app_data");
        if (qqfile != null)
        {
            var filename = Path.Combine(uploadPath, Path.GetFileName(qqfile.FileName));
            qqfile.SaveAs(filename);
            return Json(new { success = true }, "text/html");
        }
        else 
        {
            var filename = Request["qqfile"];
            if (!string.IsNullOrEmpty(filename))
            {
                filename = Path.Combine(uploadPath, Path.GetFileName(filename));
                using (var output = System.IO.File.Create(filename))
                {
                    Request.InputStream.CopyTo(output);
                }
                return Json(new { success = true });
            }
        }
        return Json(new { success = false });
    }
}

Index.cshtml查看:

<script src="@Url.Content("~/Scripts/valums/fileuploader.js")" type="text/javascript"></script>

<div id="file-uploader">       
    <noscript>          
        <p>Please enable JavaScript to use file uploader.</p>
    </noscript>         
</div>

<script type="text/javascript">
    var uploader = new qq.FileUploader({
        element: document.getElementById('file-uploader'),
        action: '@Url.Action("upload")'
    });
</script>

您还可以在布局中包含CSS:

<link href="@Url.Content("~/Scripts/valums/fileuploader.css")" rel="stylesheet" type="text/css" />

似乎是IE缓存问题,如果你正在使用Ajax&amp; GET,在Ajax参数的get参数中添加时间戳值,这样就可以做到这一点:

$.ajax({
  url : "http:'//myexampleurl.php' + '?ts=' + new Date().getTime(),
  dataType: "json",
  contentType: "application/json; charset=utf-8", 
  .
  .
  //more stuff

如果您使用的是java spring

@RequestMapping(value = "/upload", method = RequestMethod.POST, produces = "application/json")
public @ResponseBody YourObject excelUplaod(@RequestHeader("X-File-Name") String filename, InputStream is) {
    // chrome or firefox
}

@RequestMapping(value = "/upload", method = RequestMethod.POST,headers="content-type=multipart/*", produces = "text/html")
public @ResponseBody  ResponseEntity<YourObject> uploadByMultipart(@RequestParam(value = "qqfile") MultipartFile file) {
    // IE
    try {
        String fileName = file.getOriginalFilename();
        InputStream is = file.getInputStream();

        // more stuff

    } catch (Exception e) {
        logger.error("error reading excel file", e);
    }   
}
