What could be the reason my ng-if is not functioning properly? The div is not being hidden as expected

How can I make a div in my Angular app appear if a variable is true and disappear if it is false?

I've tried implementing the functionality, but it doesn't seem to be working correctly. You can view my code on JSFiddle.

Could someone help me understand what the issue might be?

HTML

<div ng-controller="MyCtrl">
    <div id="newProjectButton" class="project" ng-click="newProjectActive()" ng-if="!creatingNew">
            <h1> + </h1>
            <h3> New Project </h3>
    </div>
    <div id="newProjectActive" class="project" ng-if="creatingNew">
        <form>
            <input name="name" ng-model="newProjectName" type="text"></input>
            <button ng-click="newProject()" type="submit" class='btn btn-primary'>Save</button>
        </form>
    </div>
</div>

JS

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

function MyCtrl($scope) {
    $scope.name = 'Superhero';

    $scope.creatingNew = false;

    $scope.newProjectActive = function () {
        $scope.creatingNew = true;
    }

    $scope.newProject = function () {
        alert($scope.newProjectName);
    }

}

Answer №1

It seems that your Angular version is 1.0.1, which does not support the directive ng-if. This directive was introduced in angular 1.1.5. For more information, you can refer to this article and also check it in the Angular under the Directives topic in the change log

AngularJS first added the ngIf directive in 1.1.5

Please consider updating your Angular version.

Here is a Demo

Your controller should be like

myApp.controller("MyCtrl" , function($scope) {

as global controllers are not supported by default in Angular 1.3... check this one

Answer №2

Initially, upon reviewing your fiddle, I noticed an outdated version of your example present.

Furthermore, a possible reason for the issue is that you were using Angular in version 1.0.1 in that particular example, and it seems like that version did not support ng-if. Upgrading to the latest version should resolve the issue.
