[SOLVED] How to fade out element using ng-hide with AngularJS?

How to fade out element using ng-hide with AngularJS?

I can currently show/hide an element according to a boolean condition in my controller. How can I fade the element out if the condition is true instead of just instantly hiding it?

<div id='conversion-image' ng-hide="pages.length > 0">
    generating pages...
    <br />
    <img src='Images/ajax-loader-blue.gif' />
</div>

I also already have the ngAnimate dependancy included as well.

var app = angular.module("app", ["ngAnimate"]);

Solution

You can do it with CSS and ng-animate as the following:

.fade-out.ng-hide {
  opacity: 0;
}

.fade-out.ng-hide-add, .fade-out.ng-hide-remove {
  transition: all linear 0.5s;
}

.check-element {
  border: 1px solid black;
  opacity: 1;
  padding: 10px;
}

<head>
  <meta charset="UTF-8">
  <link href="animations.css" rel="stylesheet" type="text/css">
  <script src="//code.angularjs.org/snapshot/angular.min.js"></script>
  <script src="//code.angularjs.org/snapshot/angular-animate.js"></script>      
</head>

<body ng-app="ngAnimate">
  Hide: <input type="checkbox" ng-model="checked" aria-label="Toggle ngHide"><br />
  <div class="check-element fade-out" ng-hide="checked">
    I fade out when your checkbox is checked.
  </div>
</body>
