how to use jquery file upload angular version?

问题

here is how I use angular jquery file upload

var album = angular.module('album', ['restangular', 'blueimp.fileupload']),

.controller('somecontroller',function($scope,){
    $scope.options = {
        something
    }

 })

all I did was set the scope.options, change the controller ,and everything just magically works

setup the jquery file upload seems quite easy, but there are something really confuse me

how can I call the jquery file upload's callback function. for example, if the files uploaded successfully,I want to update the ui by calling fileuploaddone function ,it confuse me because there is no added file in my controller.

I'm new to angularJS, please help me to understand the workflow of angular jquery file upload

the blueimp.fileupload uses events that are fired via $emit to notify parent scopes:

             on([
                'fileuploadadd',
                'fileuploadsubmit',
                'fileuploadsend',
                'fileuploaddone',
                'fileuploadfail',
                'fileuploadalways',
                'fileuploadprogress',
                'fileuploadprogressall',
                'fileuploadstart',
                'fileuploadstop',
                'fileuploadchange',
                'fileuploadpaste',
                'fileuploaddrop',
                'fileuploaddragover',
                'fileuploadchunksend',
                'fileuploadchunkdone',
                'fileuploadchunkfail',
                'fileuploadchunkalways',
                'fileuploadprocessstart',
                'fileuploadprocess',
                'fileuploadprocessdone',
                'fileuploadprocessfail',
                'fileuploadprocessalways',
                'fileuploadprocessstop'
            ].join(' '), function (e, data) {
                if ($scope.$emit(e.type, data).defaultPrevented) {
                    e.preventDefault();
                }
            })

That means that you can simply add an event listener in one of the parent scope controllers, e.g.:

$scope.$on('fileuploadprocessdone', function(event, files){ 
    $.each(files, function (index, file) {
        //do what you want
    });
});

You can also override the default handleResponse function in your config phase, e.g.:

angular.module('myApp', ['blueimp.fileupload']).
.config(['fileUploadProvider', function (fileUploadProvider){
    fileUploadProvider.defaults.handleResponse = function (e,data){
        var files = data.result && data.result.files;
        if (files) {
            data.scope().replace(data.files, files);
            // do what you want...
        } else if (data.errorThrown || data.textStatus === 'error') {
             data.files[0].error = data.errorThrown ||
             data.textStatus;
        }
     };     
}]);
