javascript - Why console.log in this code return undefined? -

- 

  var el = $ ('कंटेनर'); Var एंकर = नए अर्रे ('नौकरियां', 'पोर्टफोलियो', 'डॉक्स', 'इंटरएर', 'कीमत'); के लिए (var i = 0; i & lt; anchors.length; i ++) {एल.ऑन ('क्लिक', 'एक [href $ = "#' + एंकर [i] + '"]', फ़ंक्शन (e) { E.preventDefault (); console.log (एंकर [i]); $ .scrollTo ('a [name =' '+ anchors [i] +' "] ');}); };    
 
 
 जब आप उस तत्व पर क्लिक करते हैं,  i  होता  anchors.length  के मान में वृद्धि हुई।  
 आपके क्लिक हैंडलर का  i  का संदर्भ है।  
 एक अनसुलझे प्रॉपर्टी देखने का जावास्क्रिप्ट में रिटर्न  अपरिभाषित ।  
  यह  तत्व के संदर्भ के रूप में उपयोग करना आसान होगा अन्यथा, मान के द्वारा  i  के मूल्य को पारित करने का एक तरीका ढूंढें, इसका प्रत्यक्ष संदर्भ नहीं।

-

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
