javascript - Angular.js formatter not being fired on modelValue change -


http://plnkr.co/edit/hn1pbgrsk6xqt9pwxcky?p=preview should quite self explaining

ctrl.$formatters runs when set model value, don't after update it.

according have $formatters called when view first populated? should fire everytime model value changed, what's wrong? thanks.

use natural model setter, scope[attrs.ngmodel] instead of setviewvalue.

app.directive('format', function($filter) {   return {     require: 'ngmodel',     link: function(scope, element, attrs, ctrl) {     element.unbind('input').unbind('keydown').unbind('change');         element.bind('blur', function() {             if (element.val()) {                 scope.$apply(function() {                     scope[attrs.ngmodel] = element.val();                 });                      }         });          ctrl.$formatters.unshift(function(modelvalue) {             if (modelvalue) {                 var formatted = $filter('currency')(modelvalue);                 return formatted;             }         });     } } });

you need parser work correctly.

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
