BrainTree.js与AngularJS和customVariables

Question

I am using the BrainTree.js for PCI compliance, and the tutorial I am using here:

https://www.braintreepayments.com/docs/javascript

There recommendation is to call the form by the ID like so:

var braintree = Braintree.create("YourClientSideEncryptionKey");
braintree.onSubmitEncryptForm('braintree-payment-form');

I'm using AngularJS with the form being inside a controller. So inputs such as name, card, etc are tied to a scope using ng-model:

<div class="form-group">
  <label>Card Number</label>
  <input type="text" class="form-control" name="number" ng-model="card.number" />
</div>

My question is how can I submit a form using AngularJS and BrainTree.js in a manner that uses the data collected using ng-model?

Example:

braintree.onSubmitEncryptForm({name: $scope.card.name, card: $scope.card.number});

Answer 1

In Braintree, the braintree.onSubmitEncryptForm function wraps a small amount of functionality. Basically it just grabs the jQuery form representing the input data, transforms the form fields, and then scrubs them from the DOM, before allowing the request to be submitted to the server.

Since angular includes jQuery, you could call the braintree.encryptForm($('#braintree-payment-form')); which would return the encrypted data in the DOM. You should be able to access the 'ccv' and 'number' input elements like normal (the expire doesn't need to be encrypted).

And then POST to your create_transaction method (if you're running from the tutorial).
