determine from function when an event stops with javascript -


simplified scenario:

  • i have click event on button
  • inside event call function x
  • function x returns value
  • click event changes dom using received data (actually renders jquery template)

sample code:

$("button").click(function() {     var response = functionx();      dotemplaterendering(response); //(*) });  function functionx() {     //some code      return some_value;      //the click event has finished, make little adjust generated dom (*) }

the questions are:

  • do have way determine when click stops form functionx()?
  • or there way dotemplaterendering() triggers can capture functionx() doesn't matter if return value, because @ point i'm going able execute code need

the reason behind this part of framework , can't change click event.

you can't return value function , further processing within same function. can schedule code run later using settimeout():

function functionx() {     //some code          settimeout(function() {         //the click event has finished, make little adjust generated dom (*)     }, 5);      return some_value; }

js single-threaded (if ignore web-workers), function pass timeout won't executed until after click event finishes.

alternatively, can bind second click handler same button , processing there - jquery guarantees event handlers (for same event , element) run in order they're bound.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
