[AngularJS] AngularJS系列(5) 中级篇之动画

目录

 

ng动画实际帮我们在状态切换的时候 添加特定的样式 从而实现动画效果.

一般我们会通过C3来实现具体的动画.

 

CSS定义

ng-if

<body ng-app="myApp">
    <button ng-click="show=!show">Toggle</button>
    <div ng-if="show" class="fade">Look Me</div>
 
    <script type="text/javascript">
        angular.module('myApp', ['ngAnimate'])
    </script>
</body>

.fade {
    transition: 1s linear all;
}
    .fade.ng-enter {
        opacity: 0;
    }
        .fade.ng-enter.ng-enter-active {
            opacity: 1;
        }
    .fade.ng-leave {
        opacity: 1;
    }
        .fade.ng-leave.ng-leave-active {
            opacity: 0;
        }

 

enter和leave的执行过程:

在元素创建的时候,会依次加上.ng-enter、.ng-enter-active的class,然后恢复为默认的class

同样在销毁的时候,会依次加上.ng-leave、.ng-leave-active的class,然后恢复为默认。

 

ngClass

<button ng-click="onOff=!onOff">Toggle</button>
<div ng-class="{on:onOff}" class="highlight">
    Highlight this box
</div>

.highlight {
       transition: 1s linear all;
   }
       .highlight.on-add {
           background: red;
       }
       .highlight.on {
           background: yellow;
       }
       .highlight.on-remove {
           background: blue;
       }

angular.module('myApp', ['ngAnimate'])
    .animation('.slide', [
        function () {
            return {
                enter: function (element, doneFn) {
                    jQuery(element).fadeIn(1000, doneFn);
                },
 
                move: function (element, doneFn) {
                    jQuery(element).fadeIn(1000, doneFn);
                },
 
                leave: function (element, doneFn) {
                    jQuery(element).fadeOut(1000, doneFn);
                }
            }
        }
    ]);

其中的enter move leave 对应状态变化的事件,详情建议参考源码中的$$AnimateJsProvider.
