[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

图(实际上,图并不能展现出什么):

 

 

HTML

<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>

 

CSS

        .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

这里只截取关键代码

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

CSS

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

效果图:

 

 

1.5.8支持的指令与动画样式:

DirectiveSupported Animations
{@link ng.directive:ngRepeat#animations ngRepeat} enter, leave and move
{@link ngRoute.directive:ngView#animations ngView} enter and leave
{@link ng.directive:ngInclude#animations ngInclude} enter and leave
{@link ng.directive:ngSwitch#animations ngSwitch} enter and leave
{@link ng.directive:ngIf#animations ngIf} enter and leave
{@link ng.directive:ngClass#animations ngClass} add and remove (the CSS class(es) present)
{@link ng.directive:ngShow#animations ngShow} & {@link ng.directive:ngHide#animations ngHide} add and remove (the ng-hide class value)
{@link ng.directive:form#animation-hooks form} & {@link ng.directive:ngModel#animation-hooks ngModel} add and remove (dirty, pristine, valid, invalid & all other validations)
{@link module:ngMessages#animations ngMessages} add and remove (ng-active & ng-inactive)
{@link module:ngMessages#animations ngMessage} enter and leave

 

 

JS定义

HTML

<body ng-app="myApp" ng-init="items=[1,2,3,4,5,6]">
    <button ng-click="show=!show">Toggle</button>
    <div ng-if="show" ng-repeat="item in items" class="slide">
        {{ item }}
    </div>
</body>

js操作

        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.
