The error means detectNetwork(cardNumberToCheck) evaluates to undefined.

This is because there is no return in case there is absolutely no match for re[card].test(cardNumber)

It looks like you are trying to directly modify a context object inside a consumer. This isn't going to work. You need to modify the context value at the point that it is Provided to the React application.

As a rule, context consumers shall not mutate or modify a context value.

Now, I am unfamiliar with react-sanctum, but after briefly reviewing the documentation, it does not apepar that you are given access to the context provider.

You will need to find a different way to pass propertyObject down to your child component. Either pass by props, or create a new context and render a Context.Provider above your child component.

Value of j in your code ranges between 17 and 19. While length of your string i.e. var cardNum is 13 characters + 3 characters of var prefix. So basically length of your resulting cardNum variable is 16. Syntax of slice function is str_name.slice(startPointPosition, endPointPosition); And in the code above endPointPosition i.e. value of var j is always greater than total length of cardNum. If you change value of j to less than 16 you can see the change.

Isn't this a security risk?

Only if the server-side code believes the costs submitted from the client without checking them.

I can't see you've included your JQuery library.

Put this somewhere in your code (e.g at the bottom, above your

Or you can download the whole library locally to your computer and refer to it that way instead.

You are passing wrong value inside chart.selectAll function

Replace the function:

As stated in this documentation: bot-builder-dotnet-request-payment In order to use the Bot Builder Payments library, you must first:

Create and activate a Stripe account if you don't have one already.

Sign in to Seller Center with your Microsoft account.

Within Seller Center, connect your account with Stripe.

Within Seller Center, navigate to the Dashboard and copy the value of MerchantID.

Update your bot's Web.config file to set MerchantId to the value that you copied from the Seller Center Dashboard.

At this time, the Bot Framework SDK supports only Stripe payments directly. If you are using some other provider, you will need to add support for it manually.

Also note: as of 2.25.2019, Bot Builder V4 sdk does not have payments support built in. The Bot Builder V3 sdk does: https://github.com/Microsoft/BotBuilder-Samples/tree/v3-sdk-samples/CSharp/sample-payments (Also, the Bot Framework Emulator V4 does not yet support payments: https://github.com/Microsoft/BotFramework-Emulator/issues/1324 The V3 emulator can be downloaded from here: https://github.com/Microsoft/BotFramework-Emulator/releases/tag/v3.5.37 )

there is a gem that helps us do this called activerecord-import.

Long story short: you don't.

Payment Request API is not a replacement for payment processors. The browser itself has no means to process the funds transfer to your account - it can't even validate whether the provided payment method is valid (though Android Pay can do this).

Per Introducing the Payment Request API doc (emphasis mine):

...

The browser then presents the payments UI to the user, who selects a payment method and authorizes the transaction. A payment method can be as straightforward as a credit card that is already stored by the browser, or as esoteric as third-party application written specifically to deliver payments to the site (this functionality is coming soon). After the user authorizes the transaction, all the necessary payment details are sent directly back to the site. For example, for a credit card payment, the site will get back a card number, a cardholder name, an expiration date, and a CVC.

...

In other words, the Payment Request API is just an easier, safer way for you to collect the user's card number and other info necessary to process a payment. Once you receive this information, it's pretty much the same as if the user submitted it via a normal form. You still need a payment processor (or something similar) to actually create a transaction.
