Javascript: function and its argument -


I have a problem with my function and its arguments ... this code is: < / P> 

  function alab () {var up = arguments [0]; Var id = logic [1]; Lane = arguments Long-3; For (var an = 1; a & lt; = 10; a ++) {arg = (logic [2] + a); // id tag html: [nome] [num] document.getElementById (arg) .style.display = "block"; } (Var i = 3; i & lt; len; i ++) {warning ('test1'); Document.getElementById (argument [i]). Style.display = "none"; Warning ('test2'); } Change_price (above, id); }   
 The script is hanging in another cycle: It prints  'test1' , but does not print  'test2'  . Where's the error? Thx all;)   
 
 
 Note that this advice should be used for all things:   (var i = 3; i & lt; len; i ++) {var node = document.getElementById (argument [i]); If (node) {node.style.display = "none"; In other words, if any element can be found if you are not 100% sure to be even more pedantic:   i

    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...
