jquery - .animate callback in other .animate load 2 times -


i want this:

  1. scroll 440 top
  2. open #detail animation
  3. load id.html inside #detail
  4. made css animation on html content

i want step step:

step 2/ executed after step 1/

step 3/ executed after step 2/

step 4/ executed after step 3/

but have 1 problem : .load function executed twice. don't understand why. 

$('html,body').animate({scrolltop:(440)}, 1300,'easeinsine', function() {     $('#detail').animate({height: detail_height}, 800, function() {         $('#detail').load('pages/web/' + id + '.html', function() {             //do     });     }); });

when animate n elements, callback happen n times. that's intended behavior.

if wish single callback animating multiple elements, use promise object.

$('html,body').animate({scrolltop:(440)}, 1300,'easeinsine').promise().done(function() {     $('#detail').animate({height: detail_height}, 800, function() {         $('#detail').load('pages/web/' + id + '.html', function() {             //do         });     }); });

the alternative select html or body, not both.

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
