jQuery's index method doesn't count right? -


उदाहरण 

  & lt; ul & gt; & Lt; li & gt; 0 & lt; / li & gt; & Lt; li & gt; 1 & lt; / li & gt; & Lt; li & gt; 2 & lt; / li & gt; & Lt; li & gt; 3 & lt; / li & gt; & Lt; / ul & gt; & LT; ul & gt; & Lt; li वर्ग = "चार" & gt; 0 & lt; / li & gt; # फिर से 0 & lt; li & gt; 1 & lt; / li & gt; # फिर 1 & lt; / ul & gt; $ ("Li")। क्लिक करें (फ़ंक्शन () {console.log ($ (this) .index ());});   
 जब मैं "चार" वर्ग के साथ ली पर क्लिक करता हूं, तो मैं "4" कैसे प्राप्त कर सकता हूं? डिफ़ॉल्ट रूप से यह 0 से शुरू होता है, यदि नए मूल तत्व में।   
 
 
 आपका HTML मार्कअप अमान्य है  li  को  & lt; / li & gt;  नहीं  का उपयोग करके & lt; li & gt;  बंद करने की आवश्यकता है। इसके बाद, आपको  0  अपेक्षित रूप से मिलेगा:  
    
 यदि आप वर्तमान क्लिक के सूचक को प्राप्त करना चाहते हैं < कोड> ली  तत्व DOM के अंदर, आप उपयोग कर सकते हैं:  
  $ ("li")। क्लिक करें (फ़ंक्शन () {console.log ($ (this) .index ( 'ली'));});   
 यह आपको  4  देगा यदि आप  li  पर वर्ग  चार  पर क्लिक करते हैं।  >

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...
