如何获取文件流中的图片路径？

[嗜血狂魔]

如题，我用文件流的方式上传一张照片，现在我想把文件路径获取出来，却不知道该怎么做，求助。
这是js：

$("#userImg").change(function () {
            if (FileReader) {
                var reader = new FileReader(), file = this.files[0];
                reader.onload = function (e) {
                    $("#userImage").attr("src", e.target.result);
                    $("#smallImg").attr("src", e.target.result);
                };
                reader.readAsDataURL(file);
                $("#imgUrl").val();
            }

            var jcrop_api, boundx, boundy;
            $("#userImage").Jcrop({
                onChange: updatePreview,
                onSelect: updatePreview,
                aspectRatio: 1,
                maxSize: [300, 300],
                minSize: [50, 50],
                setSelect: [0, 0, 100, 100]
            }, function () {
                var bounds = this.getBounds();
                boundx = bounds[0];
                boundy = bounds[1];

                jcrop_api = this;
            });

            function updatePreview(c) {
                if (parseInt(c.w) > 0) {
                    var rx = 120 / c.w;
                    var ry = 120 / c.h;

                    $("#smallImg").css({
                        width: Math.round(rx * boundx) + "px",
                        height: Math.round(ry * boundy) + "px",
                        marginLeft: "-" + Math.round(rx * c.x) + "px",
                        marginTop: "-" + Math.round(ry * c.y) + "px"
                    });
                }

                $("#point").val(c.x + "," + c.y + "," + c.x2 + "," + c.y2 + "," + c.w + "," + c.h);
            }
        });

这是html：

<div id="tab_3-4" class="tab-pane">
                    <form id="UserInfoForm" class="form-horizontal form-bordered form-row-stripped" method="post">
                        <div class="form-body">
                            <div class="alert alert-success display-hide">
                                <button class="close" data-close="alert"></button>
                                <span id="danger"></span>
                            </div>
                            <div class="alert alert-success display-hide">
                                <button class="close" data-close="alert"></button>
                                <span id="success"></span>
                            </div>
                            <div>
                                <div style="display: none;"></div>
                            </div>
                            <div class="form-group">
                                <label class="control-label col-md-3">头像</label>
                                <div class="col-md-4">
                                    <div class="input-group">
                                        @*<span class="input-group-addon"><i class="fa fa-lock"></i></span>*@
                                        <input type="file" id="userImg" name="userImg" value="" />
                                    </div>
                                    <div class="col-md-4">
                                        <span>原始图片</span>
                                        <img id="userImage" style="max-width: 300px; max-height:300px; height: 300px; width: 300px;" alt="" />
                                        <div style="width: 100px; height: 100px; overflow: hidden;">
                                            <span>最终显示效果</span>
                                            <div style="width: 120px; height: 120px; overflow: hidden;">
                                                <img id="smallImg" alt="" />
                                                <input type="hidden" id="point" name="point" value="" />
                                                <input type="hidden" id="imgUrl" name="imgUrl" value="" />
                                            </div>
                                        </div>
                                    </div>
                                </div>
                            </div>
                        </div>
                        <div class="form-actions fluid">
                            <div class="row">
                                <div class="col-md-12">
                                    <div class="col-md-offset-3 col-md-9">
                                        <a id="Save" class="btn btn-primary">保存</a>
                                        <a href="#" class="btn default" id="Cancel">返回</a>
                                    </div>
                                </div>
                            </div>
                        </div>
                    </form>
                </div>

直接取value和src的就不用说了，如果有用的话我不会用这么麻烦的方式。还有我用的视图框架是Razor，所以服务器控件也不用说了，求高手指教，谢谢。

我记忆中多年之前好像尝试过.outerHTML属性，不过好像最后也没成功的话
