### Scan barcode

window.plugins.zxingPlugin.scan(params, onSuccess, onFailure)

Arguments:

- **params**: All parameters are optional:

```javascript
    {
        'prompt_message':'Scan a barcode', // Change the info message. A blank message ('') will show a default message
        'orientation_locked':true, // Lock the orientation screen
        'camera_id':0, // Choose the camera source
        'beep_enabled':true, // Enables a beep after the scan
        'scan_type':'normal', // Types of scan mode: normal = default black with white background / inverted = white bars on dark background / mixed = normal and inverted modes
        'barcode_formats':[
            'QR_CODE',
            'CODE_39',
            'CODE_128'], // Put a list of formats that the scanner will find. A blank list ([]) will enable scan of all barcode types
        'extras':{} // Additional extra parameters. See [ZXing Journey Apps][1] IntentIntegrator and Intents for more details
    }
    ```

- **onSuccess**: function (s) {...} _Callback for successful scan._
- **onFailure**: function (s) {...} _Callback for cancelled scan or error._

Return:

- success('scanned bar code') _Successful scan with value of scanned code_
- error('cancelled') _If user cancelled the scan (with back button etc)_
- error('misc error message') _Misc failure_
