javascript - Web MIDI API not implemented in Chrome Canary? -


Support for

has been added to Chrome Canary

Why, when I requestMIDIAccess in the Javascript console and I hit the hit, so do I "Referrer: request MIDIAccess not defined"?

, it should be a defining function.

What gives?

The Web MIDI API is only available in Chrome version 43 and new by default.

In previous versions it is not enabled by default, but can be enabled in the form of experimental feature flag in Chrome, load special URL chrome: // flag And search the page for "Enable Web MIDI API".

The options on the Flags page require the browser to restart before it becomes effective. The hidden features behind these flags are in an experimental position and are subject to change at any time, so the APIs in older versions Can be different, which is available in Chrome 43

Also keep in mind that the request is a method of the MIDIAccess function window.navigator , not directly window . So you should call it navigator.requestmidiixx . Need to call as

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up.

Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
