HTML代码：

  <form enctype="multipart/form-data">
                    <div class="row" style="height: 500px">
                        <input id="file-1" type="file" multiple class="file" data-overwrite-initial="false" data-min-file-count="1">
                    </div>
                </form>

//上传    
   $("#file-1").fileinput({
            uploadUrl: '/Handler/upload.ashx', // 图片上传URL
            allowedFileExtensions: ['jpg', 'png', 'gif'],
            overwriteInitial: false,
            maxFileSize: 1000,
            maxFilesNum: 10,
            allowedFileTypes: ['image', 'video', 'flash'],
            slugCallback: function (filename) {
                return filename.replace('(', '_').replace(']', '_');
            }
        });

   //回调函数 当上次成功之后 返回
   $("#file-1").on("fileuploaded", function(event, data, previewId, index) {
       
            alert(data.response.JsMessage)

 })

upload.ashx 一般处理程序，返回json 格式：

context.Response.Write(JsonConvert.SerializeObject(new { success = true, JsCode = 1, JsMessage = "返回的信息" }));
