javascript - Calculating how many times 'ng-repeat' has looped, then export as a string/value in Angular.js? -


i trying build 'like' function in angular.js app. have basic 'like' section, following code:

$scope.likeclicked = function () {        if (!hasliked) {           hasliked = true;           $scope.liked = 'unlike';           $scope.likecount += 1;       } else {           hasliked = false;           $scope.liked = 'like';           $scope.likecount -= 1;                 }    };

what want achieve, , because 'likes provided json file loops 'ng-repeat', function calculates how many likes there in json file. note, json file being provided doesn't explicitly state 'likes' numerically, know them having 'name' object in file.

please help, have never used json before!

thanks.

don't try answer out of ng-repeat. that's sorta backwards - why dom lookup piece of information that's available on scope? want this:

$http.get('likes.json').success(function(data) {    $scope.likes = data;  });  $scope.addlike = function(item) {     // add item $scope.likes }

then in html can like:

<p>you have liked {{likes.length}} items.</p> <ul>     <li ng-repeat="item in items">         {{item}}         <button ng-click="addlike(item)"></button>     </li> </ul>

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 ...
