问题
I have followed the following tutorial in order to integrate the notorious bluimp jQuery file uploader in my AngularJS project.
After some research I found that in the options array, witihn the jquery.fileuploader.js file, there is an option called autoUpload, which when set to true upload the file automatically. I tried to disable it(false, undefined), but quickly I learned out that this causes the upload not to function at all, not even on the form submit.
I need to trigger the upload manually, say within another callback, or by a click event. can that be done?.
code:
app.directive("fileupload", function() {
return {
restrict: "A",
scope: {
done: "&",
progress: "&",
fail: "&",
uploadurl: "=",
customdata: "&"
},
link: function(scope, elem, attrs) {
var uploadOptions;
uploadOptions = {
url: scope.uploadurl,
dataType: "json"
};
if (scope.done) {
uploadOptions.done = function(e, data) {
return scope.$apply(function() {
return scope.done({
e: e,
data: data
});
});
};
}
if (scope.fail) {
uploadOptions.fail = function(e, data) {
return scope.$apply(function() {
return scope.fail({
e: e,
data: data
});
});
};
}
if (scope.progress) {
uploadOptions.progress = function(e, data) {
return scope.$apply(function() {
return scope.progress({
e: e,
data: data
});
});
};
}
return elem.fileupload(uploadOptions).bind("fileuploadsubmit", function(e, data) {
return data.formData = {
JSON.stringify(scope.customdata())
};
});
}
};
});
app.service('uploadService', function(authService) {
var initializeFn, processFn;
initializeFn = function(e, data, process) {
var upload;
return upload = {
message: '',
uploadurl: authService.getBaseUrl() + '/applications/',
status: false
};
};
processFn = function(e, data, process) {
var file, upload;
upload = {};
upload.successData = [];
upload.status = true;
upload.error = false;
if (process === 'done') {
upload.message = data.result.result;
console.log(data);
file = data.result.resume;
upload.successData = {
// name: file.name,
// fullUrl: file.url,
// thumbUrl: file.thumbnail_url
};
} else if (process === 'progress') {
upload.message = 'Uploading....!!!';
} else {
upload.error = true;
upload.message = 'Please try again';
console.log(e, data);
}
return upload;
};
return {
process: processFn,
initialize: initializeFn
};
});
app.controller('applyCtrl', function($scope, $routeParams, uploadService){
$scope.model.formData = {};
$scope.model.formData.job = $routeParams.jobId;
$scope.uploadLayer = function(e, data, process) {
return $scope.uploadReturn = uploadService.process(e, data, process);
};
$scope.customData = function() {
return $scope.model.formData;
};
return $scope.uploadReturn = uploadService.initialize();
});
view:
<form class="applyForm" ng-submit="uploadLayer(e, data, 'progress')">
<fieldset>
<div class="formLine">
<div class="wideFieldContainer">
<input id="testUpload" type="file" fileupload customdata="customData()" name="resume" uploadurl="uploadReturn.uploadurl" done="uploadLayer(e, data, 'done')" fail="uploadLayer(e, data, 'fail')" progress="uploadLayer(e, data, 'progress')" />
</div>
</div>
</fieldset>
</form>

Blueimp has an AngularJS version of jQuery File Upload available.
It includes a fileUpload directive and a FileUploadController with a submit() method that you can call manually.
You can see a working version at http://blueimp.github.io/jQuery-File-Upload/angularjs.html.
One thing you should pay attention to: make sure you load all .js files from the example in the correct order to avoid problems (cf. source of the example page).
Hope that helps!
UPDATE AFTER YOUR COMMENT:
When using the AngularJS version of jQuery File Upload, you create a form tag with the file-upload attribute like this:
<!-- Create a file upload form with options passed in from your scope -->
<form data-file-upload="options" data-ng-controller="YourController">
<!-- This button will trigger a file selection dialog -->
<span class="btn btn-success fileinput-button" ng-class="{disabled: disabled}">
<span>Add files...</span>
<input type="file" name="files[]" multiple="" ng-disabled="disabled">
</span>
<!-- This button will start the upload -->
<button type="button" class="btn btn-primary start" data-ng-click="submit()">
<span>Start upload</span>
</button>
<form>
Then in your controller you can assign the options for the jQuery File Upload like this:
angular.module('yourModule')
.controller('YourController', [$scope, function($scope){
// Options you want to pass to jQuery File Upload e.g.:
$scope.options = {
maxFileSize: 5000000,
acceptFileTypes: /(\.|\/)(gif|jpe?g|png)$/i
};
}]);
You can assign the submit() handler to any ng-click attribute as long as it is inside the form (and thus can access the method).
Let me know if you need further help...
EXTRA SAMPLE CODE FOR SUCCESS CALLBACK:
If you need to run a callback function after all uploads have been completed, you can listen to the fileuploadstop event that is broadcasted by Blueimp:
// Listen to fileuploadstop event
$scope.$on('fileuploadstop', function(){
// Your code here
console.log('All uploads have finished');
});
Hope that helps!
