` instead.
Now you need to display uploaded files, all you need to do is to loop files array.
Files array is attached to flow object named `$flow`.
````html
| {{$index+1}} |
{{file.name}} |
````
file is instance of [FlowFile](https://github.com/flowjs/flow.js#flowfile).
### Quick setup
````html
```
Need more examples?
============
Clone this repository and go to "ng-flow/samples/basic/index.html".
Single image upload "ng-flow/samples/image/index.html".
How can I drop files?
============
Use `flow-drop` directive:
````html
Drag And Drop your file here
````
Note: in most cases `flow-drop` must be used together with `flow-prevent-drop` directive on `body`
element, because it prevents file from being loaded in the browser.
### Prevent dropping files on a document
Use `flow-prevent-drop` directive on `body` element:
````html
````
### How to add some styles while dropping a file?
Use `flow-drag-enter` directive:
````html
````
Note: `flow-drag-leave` attribute can't be used alone, it is a part of `flow-drag-enter` directive.
### How to dynamically disable drop area?
````html
Drag And Drop your file here
````
See example at `samples/dataurl/`.
How can I preview uploaded image?
============
Use flow-img directive:
````html
![]()
````
Image will be automatically updated once file is added. No need to start upload.
How can I set options for flow.js?
============
Use config:
````javascript
var app = angular.module('app', ['flow'])
.config(['flowFactoryProvider', function (flowFactoryProvider) {
flowFactoryProvider.defaults = {
target: '/upload',
permanentErrors:[404, 500, 501]
};
// You can also set default events:
flowFactoryProvider.on('catchAll', function (event) {
...
});
// Can be used with different implementations of Flow.js
// flowFactoryProvider.factory = fustyFlowFactory;
}]);
````
also can be configured on "flow-init" directive:
````html
````
How can I catch events?
============
Events are listed inside `flow-init` directive:
````html
````
### How can I catch an event in a controller?
If controller is on the same scope as `flow-init` directive or in a child scope,
then we can catch events with `$on`. Events are prefixed with `flow::`.
````javascript
$scope.$on('flow::fileAdded', function (event, $flow, flowFile) {
event.preventDefault();//prevent file from uploading
});
````
second argument is always a `flow` instance and then follows event specific arguments.
How can I assign flow to a parent scope?
============
Use `flow-name` attribute and set it to any variable in the scope.
````html
... Flow is set to obj.flow ...
I have uploaded files: #{{obj.flow.files.length}}
````
````javascript
$scope.obj = {}; // variable "obj" must be initialized on the scope
````
How can I initialize flow with an existing flow object ?
============
Use `flow-object` attribute and set it with the existing flow object on scope.
````html
... Flow is initialized with existingFlowObject, no new Flow object is created ...
There are already {{ existingFLowObject.files.length }} files uploaded,
which is equal to {{ $flow.files.length }}.
````
How can I support older browsers?
============
Go to https://github.com/flowjs/fusty-flow.js
and add to your config:
````javascript
var app = angular.module('app', ['flow'])
.config(['flowFactoryProvider', function (flowFactoryProvider) {
flowFactoryProvider.factory = fustyFlowFactory;
}]);
````

============
To ensure consistency throughout the source code, keep these rules in mind as you are working:
* All features or bug fixes must be tested by one or more specs.
* With the exceptions listed below, we follow the rules contained in [Google's JavaScript Style Guide](http://google-styleguide.googlecode.com/svn/trunk/javascriptguide.xml):
* Wrap all code at 100 characters.
* Instead of complex inheritance hierarchies, we prefer simple objects. We use prototypical
inheritance only when absolutely necessary.
