A step-by-step guide on how to smoothly hide an element using ng-hide in AngularJS

Currently, I am able to toggle an element's visibility based on a boolean condition in my controller. However, I am looking for a way to smoothly fade out the element if the condition is true instead of instantly hiding it. Any suggestions on how to achieve this?

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

I have already included the ngAnimate dependency in my code.

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

Answer №1

If you want to achieve this effect using CSS and the ng-animate, you can follow these steps:

.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>

In the official AngularJS guidelines, it discusses:

How to Customize .ng-hide

The default behavior of the .ng-hide class is to apply display: none !important styling. If you want to modify the hiding functionality using ngShow/ngHide, you can easily override the styles for the .ng-hide CSS class. It's important to note that the appropriate selector to use is actually .ng-hide:not(.ng-hide-animate) in order to accommodate any additional animation classes that may be included.

<style>
    .animate-show,.animate-hide {

       -moz-transition:all linear 1s;
       -ms-transition:all linear 1s;
       -o-transition:all linear 1s;
       transition:all linear 1s;
  }

   .animate-show.ng-hide-remove,
    .animate-hide.ng-hide-add.ng-hide-add-active {
        opacity: 0;
        display: block !important;
    }

    .animate-hide.ng-hide-add,

Answer №4

To create a fading effect on your div, simply apply the fade class and include a button to toggle the visibility of the content. You can customize the condition for hiding using ng-hide = "your_own_condition"

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

<button ng-click="condition=!condition">Toggle</button>

<style>
.fade.ng-hide {
  transition:0.5s linear all;
  opacity:0;
}
</style>
