Call external function from AngularJS

I admit that I'm new to AngularJS and still don't know it well. However, my problem is that I need to call a function in an external .js file from a controller.

This is my code:

menuapp.controller("barcodeController", function($scope, $cordovaBarcodeScanner) {

$scope.scanBarcode = function() {
    $cordovaBarcodeScanner.scan().then(function(imageData) {
        var code = 36;//imageData.text.split('=')[1];
        if(code) {
            //external function
        }
        console.log("Barcode Format -> " + imageData.format);
        console.log("Cancelled -> " + imageData.cancelled);
    }, function(error) {
        console.log("An error happened -> " + error);
    });
};
});

I'm using this to scan a barcode, extract what's after the "=" and send it to an external function. However I can't simply call those function and I can't figure a simple way to do that.

Any help?

You need to create a global instance of the function.

Add a line:

var abc= new funcName();

at the end of the File and you can use this line (var abc= new funcName();) in your controller to invoke any methods from this file by using abc.methodName.

If you reference the external Javascript file from your html, you will have access to the function from within your controller.

Html:

<script src="URL"></script>

Controller:

if(code) {
     openrestaurant(code);
}
