IE 8中jquery file upload 上传图片没反应

jquery file upload对IE的支持不是很好，所以很多方法不支持，例如progressall
什么的，所以你得JS可能不正确，之前我写了一个文件上传的，可参考

define(function(require, exports, module) {
    var $ = require("$");
    require("jquery.validate");
    require("bootstrap_commonrequire");
    require("jquery-form");

    var bootbox = require('bootbox');
    var Widget = require("widget");
    var template = require("./ImgUpload.tpl");
    var fileKey = null;
    
    $(document).ready(function() {
        // 图片删除事件
        $('.del_pic').off().live("dblclick",function(){
            var ele = $(this);
            var key = $(this).attr("val");
            bootbox.confirm('确定删除？',function(YesOrNo){
                if(YesOrNo){
                    var url = "/base/product/filedel/"+key+".do";
                    $.ajax({
                        type : "GET",
                        url : url,
                        async:false,
                        data:{},
                        success : function(d) {
                            bootbox.alertTimeout('删除成功！');
                            ele.parent().remove();
                        },
                        error : function(data) {
                            bootbox.alertTimeout('删除出错！');
                        }
                    });
                }
            });
        });
    });
    
    // 初始化老照片
    function initOldImgList(){
        
        $('#oldFileDiv').empty().append('');
        $.getJSON("/base/product/filelist/"+fileKey+".do",function(data) {
            $.each(data,function(index, fileKey) {
  
              $('#oldlist').append('

            });

            return "Firefox";  
       }  
       if(navigator.userAgent.indexOf("Chrome")>0) {  
            return "Chrome";  
       }   
       if(navigator.userAgent.indexOf("Camino")>0){  
            return "Camino";  
       }

       }  
    }  
    
    // 文件类型
    function checkFileType(fileName){
        if(typeof(fileName) == "undefined" || fileName == null || fileName == ""){ 
             bootbox.alertTimeout("请选择图片！");
             return false;
        } 
        if(!/\.(gif|jpg|jpeg|png|GIF|JPG|PNG)$/.test(fileName))
        {
            bootbox.alertTimeout("图片类型必须是.gif,jpeg,jpg,png中的一种！");
            return false;
        }

    var FileUpLoadComponent = Widget.extend({
        template : template,
        setFileKey : function(fileKeyValue){
            fileKey = fileKeyValue;
        },
        afterRender : function() {
            // 输入项初始化
            var attrs = this.get("attrs");
            
            if(attrs.optType == "create"){

                // 旧图片清空
                $('#oldFileDiv').empty();
            } else if(attrs.optType == "update"){
                // 初始化fileKey
                fileKey = attrs.fileKey;

                initOldImgList();
            }

                    var bruserType = getBrowserType();
                    if(bruserType == "Firefox" || bruserType == "Chrome"){
                        var selectedFiles = slectFileElem.files;
                        if(selectedFiles == null || selectedFiles.length == 0)
                            return;

                    } 
                    
                    if(!checkFileType(fileName)){
                        return;
                    }
                    
                    $("#file-info-table").show();
                    $('.file-name').text(fileName);
                } catch(ex){
                    bootbox.alertTimeout('获取文件信息出错！');
                }
            };
            
            // 图片上传
            $('#imgUploadForm').ajaxForm({
                url : "/base/product/fileupload2.do",
                type : "POST",
                data : {
                    fileSetKey : fileKey
                },
                beforeSubmit : function(a, f, o) {
                    $('#uploadstatus').html('上传中...');
                    $('#file-upload-btn').attr("disabled", true); 
                },
                success : function(data) {
                    try {
                        data = JSON.parse(data); // 将JSON字符串解析为JSON对象
                        if (typeof (data) == 'string')

                }
            });
        }
    });

    module.exports = FileUpLoadComponent;
});

后台的

    @RequestMapping(value = "/fileupload2", method = RequestMethod.POST)
    public void upload2(HttpServletRequest request, HttpServletResponse response, @RequestParam(value = "fileSetKey", required = true) String fileSetKey) throws IOException {
        MultipartHttpServletRequest multiHttpServletRequest = (MultipartHttpServletRequest) request;
        
        HBaseFileInfo hBaseInfo = new BaseFileOper("prodpic").filesUpload(multiHttpServletRequest, fileSetKey, new String[] { "B", "M", "S" }); // 固定值：
        
        response.setCharacterEncoding("UTF-8");  
        response.setContentType("text/html");  
        try {
            JSONObject object = JSONObject.fromObject(hBaseInfo);
            response.getWriter().write(object.toString());
        } catch (IOException e) {
            response.getWriter().write("'msg'" + ":" + "'" + e.getLocalizedMessage() + "'");
        } catch (Exception e) {
            response.getWriter().write("'msg'" + ":" + "'" + "图片上传发生错误，请重试！" + "'");
        }
    }

formData: {fileSetKey:$("#pickey").val()},---这句有点奇怪，你把data alert出来呢

还有启动F11，启动ie8的调试平台，ie8确实恶心。
