当分别单击左/右按钮时，我真的很难将 AngularJS 中的内容滑动到左/右。

我知道它可以用 ng-animate 来完成，但我不确定如何在我的 AngularJS 代码中做到这一点。

下面是我的代码。如果您能帮助我，我将不胜感激。

HTML

<div class="page">
    <div class="content">
        <div class="previous-btn" ng-click="goToPrevSlide(currSlide)">
            <a href="#" ng-click="goToPrevSlide(currSlide)" class="left-arrow"></a>
        </div>
        <div class="slide">
            <img src="{{getCurrentSlide().img}}" width="800" height="500" />
        </div>
        <div class="video">
            <div id="myvideo" width="140" height="220"></div>
            <div class="speaker-info">
                <p class="speaker-name">{{getCurrentSlide().speaker}}</p>
                <p class="speaker-title">{{getCurrentSlide().title}}</p>
            </div>
        </div>
        <div class="next-btn" ng-click="goToNextSlide(currSlide)">
            <a href="#" ng-click="goToNextSlide(currSlide)" class="right-arrow"></a>
        </div>
    </div>
</div>

JS

function getPresentationData(){

    var data = {};

    data.title = 'Site's Title';

    data.pages = [];

    data.pages[0] = {};
    data.pages[0].menuTitle = 'Introduction';
    data.pages[0].slides = [];
    data.pages[0].slides[0] = {heading:'Heading 1: profile', speaker: 'Speaker's Name', title:'Expert in something', img:'content/pg-3.jpg', video:'content/videos/3.flv'};

     ...

    return data;
}

您可以侦听$routeChangeSuccess由http://docs.angularjs.org/api/ngRoute.$route调度的事件。这样在您的presentationController中您可以拥有$scope.$on('presentationController', function(angularEvent, next) {});

并根据下一个和当前位置调用goToXPage()。

您还可以查看这篇文章，该文章解释了如何使用 ng-view 实现类似的视图滑动。
