动画引导轮播标题

Question

我想为 Twitters Bootstrap 轮播的标题设置动画。在标题中，我得到了一个 h1-Tag 和四个 h4-Tag。

我希望 h1 先淡入，然后再淡入 h4-Tags。在滑动到下一张图片之前，我想先淡出 h4-Tag，然后再淡出 h1-Tag。

我的 slider.js：

$('#carousel-example-generic').on('slide.bs.carousel', function () {
    $("h1").fadeIn(2000);
});

$('#carousel-example-generic').on('slid.bs.carousel', function () {
    $("h1").fadeOut(2000);
});

我的 HTML：

    <div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
    <!-- Indicators -->
    <ol class="carousel-indicators">
        <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
        <li data-target="#carousel-example-generic" data-slide-to="1"></li>
        <li data-target="#carousel-example-generic" data-slide-to="2"></li>
    </ol>

    <!-- Wrapper for slides -->
    <div class="carousel-inner" role="listbox">
        <div class="item active">
            <img src="http://www.werkart-hannover.de/tl_files/images/projekte/neubau-einfamilienhaus-2.jpg" alt="...">
            <div class="carousel-caption">
                <h1>Here is a test title</h1>
                <h4>Test</h4>
                <h4>Test</h4>
                <h4>Test</h4>
                <h4>Test</h4>
            </div>
        </div>
        <div class="item">
            <img src="http://www.loth-haus.de/galerie/neubau_5232.jpg" alt="...">
            <div class="carousel-caption">
                <h1>Here is a test title</h1>
                <h4>Test</h4>
                <h4>Test</h4>
                <h4>Test</h4>
                <h4>Test</h4>
            </div>
        </div>
        <div class="item">
            <img src="http://www.loth-haus.de/galerie/neubau_5232.jpg" alt="...">
            <div class="carousel-caption">
                <h1>Here is a test title</h1>
                <h4>Test</h4>
                <h4>Test</h4>
                <h4>Test</h4>
                <h4>Test</h4>
            </div>
        </div>
    </div>

    <!-- Controls -->
    <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
        <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
        <span class="sr-only">Previous</span>
    </a>
    <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
        <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
        <span class="sr-only">Next</span>
    </a>
</div>

另一个问题是我的动画只适用于第二张幻灯片。 如何像我描述的那样为标题内的元素设置动画？ 这是我的小提琴：http://jsfiddle.net/7fh3o32y/

我遇到了同样的问题，终于找到了解决方案！

我只是 Jquery 的初学者，所以我相信你可以清理一下。此外，最好使用您自己的 Carousal Structure，只需将 2 个类用于您想要动画的字幕。

诀窍是使用 Animate.css 但您必须在动画字幕上禁用 Firefox 的 Ease 功能，否则会导致问题。

        function toggleH(){
