ng-Animate not working for a Hide and Show setting


I'm using AngularJS version 1.2.11. I've set a toolbar to slide in and out with a transition using ng-Animate (show and hide).

Here is the HTML:

 <div>
  <div class="full-height">
    <menu-main class="full-height pull-left"></menu-main>
    <menu-sub class="full-height pull-left" ng-show="data.active" ng-animate="'animate'">
    </menu-sub>
  </div>
</div>

And here is the CSS for the same toolbar element

.animate.fade-hide, .animate..fade-show {
    -webkit-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 3.5s;
    -moz-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 3.5s;
    -o-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 3.5s;
    transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 3.5s;
}
.animate.fade-hide, {
    position: fixed;
    top: 500px;
    opacity: 0.3;
}
.animate.fade-hide, .animate.fade-hide-active 
{
    position: fixed;
    top: 500px;
    opacity: 0.3;
}
.animate.fade-show {
    position: fixed;
    top: 100px;
        opacity: 1;
}
.animate.fade-show, .animate.fade-show-active {
    position: fixed;
    top: 100px;
        opacity: 1;
}

The animation does not work, and I'm not sure if I'm doing this correctly.


Solution

  • The ng-animate attribute is deprecated in 1.2 and no longer used. Instead, animations are now class based.

    Also make sure you are referencing angular-animate.js and adding ngAnimate as a dependent module:

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

    You then name your animations, for example 'fadein' and 'fadeout', and decorate them with some additional classes following a special naming convention that can be found in the Angular documentation.

    Another good source on the topic is Year of moo.

    Fadein example:

    /* After the transition this will be the only class remaining */
    .fadein {
      -webkit-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 1.5s;
      -moz-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 1.5s;
      -o-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 1.5s;
      transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 1.5s;
      opacity: 1; /* Default value but added for clarity */
    }
    
    /* Initial state when showing */
    .fadein.ng-hide-remove {
      opacity: 0;
      display: block !important;
    }
    
    /* Will transition towards this state */
    .fadein.ng-hide-remove.ng-hide-remove-active {
      opacity: 1;
    }
