[SOLVED] Angular validation on submit

Angular validation on submit

I am trying to create a form that, if you do not fill out any of the fields, will show an alert message if you hit submit. I am trying to work with angular validation to make this happen; however, it is not working at all. Here is the code I currently have:

(1) HTML Event Form file

  function mainController($scope, $http) {
      $scope.formData = {};

      $http.get('/api/events')
        .success(function(data) {
          $scope.events = data;
          initMap(data);
          for(i = 0; i < data.length; i++){
            console.log(data[i].eventLocation);
            //placeMarker(data[i]);
            //test(data);
          }
          //placeMarker(data);
        })
        .error(function(data) {
          console.log('Error: ' + data);
        });

      // when submitting the add form, send the text to the node API
      $scope.createEvent = function() {
        $http.post('/api/events', $scope.formData)
          .success(function(data) {
            $scope.formData = {}; // clear the form so our user is ready to enter another
            $scope.events = data;
            console.log(data);
          })
          .error(function(data) {
            console.log('Error: ' + data);
          });
        }

      // ATTEMPT AT FORM VALIDATION
      $scope.validateForm = function() {
        if (document.getElementById("inputName").value == "" || document.getElementById("inputType").value == "" || document.getElementById("inputLocation").value == "" || document.getElementById("inputDetails").value == "") {
          alert("Please fill in all required fields!");
          return false;
        }
      }
    };

<div class="col-lg-6">
                  <!-- Validate form -->
                  <form name="myForm" onsubmit="return validateForm()">
                   <div class="form-group">
                      
                      <label>Event Name</label>
                      <input type="text" name="inputName" class="form-control" ng-model="formData.eventName" placeholder="Event name">
                    </div>

                     <div class="form-group">
                       <label>Type</label>
                       <select class="form-control" id="inputType" ng-model="formData.eventType">
                         <option>Option 1</option>
                         <option>Option 2</option>
                         <option>Option 3</option>
                         <option>Option 4</option>
                       </select>
                     </div>

                     <div class="form-group">
                       <label>Location</label>
                       <select class="form-control" id="inputLocation" ng-model="formData.eventLocation">
                         <option>Location 1</option>
                         <option>Location 2</option>
                         <option>Location 3</option>
                       </select>
                     </div>

                     <div class="form-group">
                       <label>Event Details</label>
                       <textarea class="form-control" name="inputDetails" ng-model="formData.eventDetails" rows="2" placeholder="Add details about your event"></textarea>
                     </div>
                    <div class="text-center">
                      <button id="add-event"type="submit" class="btn btn-primary"  ng-click="createEvent()">Submit</button>
                    </div>
                  </form>

Solution

you can do this using ng-submit for form validation

<form name="myForm" ng-submit="validateForm()">

and for the validation use ng-model variable to validate the form

$scope.validateForm = function() { 
    if (!$scope.formData.eventName || !$scope.formData.eventType  ) {
      alert("Please fill in all required fields!");
      return false;

  }
