Unlocking the potential of input values in Angular.jsDiscovering the secret to

I'm currently experimenting with the angular date picker directive. My goal is to retrieve the entered date value from the date picker and log it to the console. However, all of my attempts so far have been unsuccessful.

Here's a snippet of my code:

HTML:

 <input class="form-control"
       ng-model="ctrl.input"
       ng-model-options="{ updateOn: 'blur' }"
       placeholder="Select a date..."
       moment-picker="ctrl.input" id='date'>

    <button ng-model='ctrl.input' ng-click="onclick()">submit</button>

JS

angular
  .module('Demo', ['moment-picker'])
  .controller('DemoCtrl', ['$scope', function ($scope) {
    $scope.onclick = function(){
      console.log(angular.element(document).find('#date').val());
    }



  }]);

Answer №1

  1. Make sure to use the controller-as syntax in your HTML and define your controller accordingly. Avoid using the older $scope-as-controller syntax.

  2. Remove the ng-model pointing to ctrl.input on your submit button, as it may cause interference.

  3. Avoid accessing elements via angular.element in view controllers; use controller properties instead. Reserve angular.element for directives and special cases only.

To improve your code, switch to controller-as in your HTML and update your controller like this:

angular
.module('Demo', ['moment-picker'])
.controller('DemoCtrl', ['$scope', function ($scope) {
   var ctrl = this 
   ctrl.onclick = function(){
      console.log(ctrl.input);
   }
}]);

Answer №2

In contrast to jQuery, where you have to select the value from the DOM, AngularJS automatically sets up two-way data binding when using ng-model.

Configuration

  ng-model="ctrl.input"

This code snippet establishes the two-way data binding for you.

To achieve your desired outcome, modify the JavaScript as shown below:

angular
  .module('Demo', ['moment-picker'])
  .controller('DemoCtrl', ['$scope', function ($scope) {
    var ctrl = this;
    $scope.onclick = function(){
      console.log(ctrl.input);
    }

  }]);

Answer №3

This code snippet will log the user input to the console.

    <html ng-app="Demo">
