javascript - jQuery submit form AFTER validating it with ajax -


I have a difficult field for which verification must be passed on the server side. So I need to send a Ajax request with this field, to get the results to capture, if the result is valid for submission of form, other intelligent closure and showing the message.

How do I do this?

I've lost a bit of "big picture" with events and callbacks.

Even so far I have. 

  $ ("form"). Submit (function (event) {event.preventDefault (); return check ();}); Function check () {var field = $ ('# myFiled'). Val (); If (! Field) {show.error ('Please enter the VIN number and retry'.); return false; } $ .getJSON ('MyURL', function) {if (! Data.valid) show. Panic ('invalid entry, please try again.');})}   
  Update  Please read the question. In case of successful verification, I will have to submit the  routine  form. Not by AJX   
 
 
  $ ("form"). Submit (function (event) {Event.preventDefault (); check and submits ();}); Function checks and submits () {var field = $ ('# myFiled'). Val (); If (! Field) {show.error ('Please enter the VIN number and retry'.); } Else {$ .getJSON ('MyURL', function (data) {if (! Data.valid) {show.error ('invalid entry, please try again.');} Else {$ .post ('yourFromPostURL ', $ (' Form '). Serialize (), function (data) {// show some of success or failure.}}}}}}}}

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. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. 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...
