javascript - Issue in rewriting scripts to be vanilla js (not jQuery) -

-

I'm rewriting my Chrome extension in the vanilla code instead of jQuery, and for the most part it's been easy is. How ever have I come in a part that does not work for purpose.

Basic jQuery-based code: 

  $ (".file.flayer"). (Work () {// relevant code using "this"}});   
 New vanilla-only code:  
  var flairs = document.querySelectorAll (".flare" content); For (var i = 0; i & lt; flairs.length; i ++) {flairs [i] .addEventListener ("click", function (event) {// indispensable code using flairs [i] }); }   
 This issue with vanilla code is that each click on  .content .flair  element is always  flairs  (i.e.  Flares [flairs.length - 1]  instead of  flairs [i] . .  
 I can not squash this bug!  
 Thank you for your time.   
 
 
 The problem was with the closure.  < See more with thanks for P> @ Arun-P-Johnny
