What is dateFilter and where can I find out more about it?

angularjs, angularjs-directive, datefilter

Solution

Date filter docs are here: http://code.angularjs.org/1.2.5/docs/api/ng.filter:date

Here's part of the docs that explain filter injection: http://code.angularjs.org/1.2.5/docs/guide/filter#using-filters-in-controllers-and-services

Filters are usually used in view expressions (`{{myDate | date:'short'}}`), but they can also be used in your JS code. Filters are injected by appending string `Filter` to the filter name (e.g. `date` -> `dateFilter`).

app.controller('MyCtrl', function($scope, dateFilter, lowercaseFilter){
  $scope.myDate = new Date();
  $scope.myDateFormatted = dateFilter($scope.myDate, 'shortDate');

  $scope.myString = 'Some String';
  $scope.myStringLowerCased = lowercaseFilter($scope.myString);
});

Problem

I am going through the Angular documentation on directives: http://docs.angularjs.org/guide/directive One of the examples on the page (full working example here http://jsbin.com/osOQOYag/3/edit?html,js,output ``` angular.module('docsTimeDirective', []) .controller('Ctrl2', function($scope) { $scope.format = 'M/d/yy h:mm:ss a'; }) .directive('myCurrentTime', function($interval, dateFilter) { function link(scope, element, attrs) { var format, timeoutId; function updateTime() { element.text(dateFilter(new Date(), format)); } scope.$watch(attrs.myCurrentTime, function(value) { format = value; updateTime(); }); element.on('$destroy', function() { $interval.cancel(timeoutId); }); // start the UI update process; save the timeoutId for canceling timeoutId = $interval(function() { updateTime(); // update DOM }, 1000); } return { link: link }; }); ``` On the line: ``` .directive('myCurrentTime', function($interval, dateFilter) { ``` I cannot for the life of me find any information on the .directive prototype and cannot find any documentation on dateFilter anywhere either. Also, I know that dateFilter is found in the un-minified version of AngularJS (although the name disappears in the minified version). Can anyone provide some guidance (and possibly a link) explaining more about dateFilter and similar functions?
