Utilizing the power of moment.js within an Angular component

Question

Utilizing the power of moment.js within an Angular component

My goal is to utilize the moment() function within double curly braces {{}} in order to present a date:

{{ moment().date(timeslot.start.value.month)
           .month(timeslot.start.value.dayOfMonth - 1)
           .format("MMMM Do")
}}

Unfortunately, I am facing an issue where no HTML is being rendered. Both month and dayOfMonth are properly defined, and I have ensured that moment.js is included correctly by testing with console.log(), which outputs the correct result for a specific date like

moment().date(6).month(6).format("MMMM Do")

, which returns "July 6th".

I'm unsure if there's a simple oversight on my part. Any suggestions would be greatly appreciated.

If you haven't already, consider using an angular wrapper like angular-moment. Using a wrapper can help avoid potential headaches with jQuery and Javascript libraries.

For a demonstration based on your code, check out this plunker example.

<body ng-controller="MainCtrl">
  <p>Hello {{name}}!</p>
  <span>{{myDate| amUtc | amLocal | amDateFormat:'MMMM Do'}}</span>
</body>

In the application, I set myDate to the current date:

var app = angular.module('plunker', ['angularMoment']);

app.controller('MainCtrl', function($scope) {
  $scope.name = 'World';
  $scope.myDate = new Date();
});

One solution is to assign the value to a $scope variable in your controller, then display it using curly brackets.

In your controller:

$scope.time = moment().date(timeslot.start.value.month)
       .month(timeslot.start.value.dayOfMonth - 1)
       .format("MMMM Do")

In your html:

{{time}}

Only variables attached to "this" or "$scope" can be accessed in the view through double curly brackets or ng-bind. Make sure to assign it to the appropriate scope for the view.

Trying to directly use the moment operation within the curly brackets may not work well because Angular might have trouble interpolating an external library and its methods like that. Simpler options are usually more successful in this case.

Connect moment to the rootScope within the app's initialization script (app.run.js):

$rootScope.moment = $window.moment;
