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"]);
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>As mentioned in the AngularJS documentation:
Overriding .ng-hide
By default, the .ng-hide class will style the element with display: none !important. If you wish to change the hide behavior with ngShow/ngHide, you can simply overwrite the styles for the .ng-hide CSS class. Note that the selector that needs to be used is actually .ng-hide:not(.ng-hide-animate) to cope with extra animation classes that can be added.
Add the following class class="animate-show animate-hide"
<div id='conversion-image' class="animate-show animate-hide" ng-
hide="model.transaction.selectedDocument.pages.length > 0">
generating pages...
<br />
<img src='Images/ajax-loader-blue.gif' />
</div>
Add the styles below
<style>
.animate-show,.animate-hide {
-webkit-transition:all linear 1s;
-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,
.animate-show.ng-hide-remove.ng-hide-remove-active {
opacity: 1;
display: block !important;
</style>
Here is a plunker example http://plnkr.co/edit/VoWwmHK57wtuyGl6npr0?p=preview
Simply use the fade class in your div and add a button to toggle your condition to see the animation on hide. You can use your own condition in 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>
