How do I extract data from the view and utilize it in the controller within an AngularJS application?

I'm currently developing an AngularJS 1.6 app that integrates with the Giphy.com API.

One of the key features is displaying an "import date" that comes directly from the API as import_datetime, which is unique to each item.

In my attempt to make the date more user-friendly, I used the following code snippet:

<p class="m-0 meta">{{giphy.import_datetime | date : "dd.MM.y" }}</p>

However, this approach did not yield the desired result.

The controller in question contains the following code:

app.controller("giphyCtrl", ["$scope", "$http", "$filter", "$timeout", function($scope, $http, $filter, $timeout) {
    var url = "https://api.giphy.com/v1/gifs/trending?api_key=PTZrBlrq8h2KUsRMeBuExZ5nHyn7dzS0&limit=240&rating=G";
    $scope.giphyList = [];
    $scope.search = "";
    // More controller logic here
}]);

It seems like a better approach would be to fetch import_datetime from the view, convert it into a JavaScript Date object, and then utilize it within the view.

Queries:

  1. How can I achieve this conversion effectively?
  2. Are there any alternative methods you would recommend?

Answer №1

One way to transform a date from giphy format into a JavaScript Date object is by creating a custom filter and using the AngularJS built-in date filter:

var myApp = angular.module('myApp', []);

myApp.filter('customDateParse', function() {
  return function(date) {
    return Date.parse(date);
  };
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
<div ng-app="myApp">
  <p>{{'2019-07-10 14:12:59' | customDateParse | date : "dd.MM.y"}}</p>
</div>
