script :

 $scope.$watch('file', function (file) {     if (file&&!file.$error) {         $scope.upload($scope.file);     } }); $scope.upload = function (file) {     upload.upload({         url: getbaseurl() + 'home/processrequest',         file: file     }).progress(function(evt) {         $scope.progresspercentage = parseint(100.0 * evt.loaded / evt.total);         console.log('progress: ' + $scope.progresspercentage + '% ' + evt.config.file.name);     }).success(function (data, status, headers, config) {         console.log('file ' + config.file.name + 'uploaded. response: ' + data);     }).error(function (data, status, headers, config) {         console.log('error status: ' + status);     }); }; 

error :

edit :

i'm using code :

   public class homecontroller : controller     {         [httppost]         [allowuploadspecialfilesonly(".pdf,.doc,.docx,ppt,pptx,.mp3")]         public jsonresult resume(httppostedfilebase file)         {             bool result;             try             {                 if (file != null && file.contentlength > 0 && file.filename != null)                 {                     string namefile = guid.newguid().tostring("n") + path.getextension(file.filename);                     var path = path.combine(server.mappath(url.content("~/temp/")), namefile);                     file.saveas(path);                 }                 result = true;             }             catch (exception exception)             {                 result = false;             }             return json(new             {                 result = result             }, jsonrequestbehavior.allowget);         }      } 

html :

<form class="form-horizontal text-center" role="form" name="upload_form" >     <div class="form-group">         <div class="btn btn-primary" ngf-pattern="'.pdf,.doc,.docx,ppt,pptx,.mp3,.apk'" ngf-select ng-model="file">send</div>     </div>     <span class="progress" ng-show="file.progress >= 0">         <div class="ng-binding" style="width:{{file.progress}}%" ng-bind="file.progress + '%'"></div>     </span> </form> 

scropt :

  $scope.upload = function (file) {                 upload.upload({                     url: getbaseurl() + 'home/resume',                     file: file                 }).progress(function(evt) {                     $scope.progresspercentage = parseint(100.0 * evt.loaded / evt.total);                     console.log('progress: ' + $scope.progresspercentage + '% ' + evt.config.file.name);                 }).success(function (data, status, headers, config) {                     console.log('file ' + config.file.name + 'uploaded. response: ' + data);                 }).error(function (data, status, headers, config) {                     console.log('error status: ' + status);                 });             }; 

this fine. progresspercentage 100% file being uploaded
