DIV Modernizr中的Drupal响应式HTML5视频背景

标签: css html5 video drupal modernizr

我正在尝试在Drupal网站主页中实施http://jsfiddle.net/mgmilcher/8R7Xx/sho/响应式HTML5视频背景,但未成功。通过本地复制所有html代码到我的页面 - front.tpl.php页面,视频和文本出现,但显然不是我想要的。一旦我将CSS添加到我的style.css表中,一切都会消失。我已将JS本地添加到网站,目前已将其添加到" theme.info"文件包含脚本[] =' name.js'。不幸的是,这似乎对结果没有任何影响。我的主题基于bootstrap,这个示例与创建的相同。

有没有人成功将此示例应用到他们的Drupal站点?我想要一个响应式背景视频,仅用于我可以添加其他内容的主要内容 - 文本,视频,并且需要能够具有滚动功能才能查看视口下方的内容。

<div class="homepage-hero-module">
    <div class="video-container">
        <div class="title-container">
            <div class="headline">
                    <h1>Welcome to our Company</h1>

            </div>
            <div class="description">
                <div class="inner">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s</div>
            </div>
        </div>
        <div class="filter"></div>
        <video autoplay loop class="fillWidth">
            <source src="http://dfcb.github.io/BigVideo.js/vids/dock.mp4" type="video/mp4" />Your browser does not support the video tag. I suggest you upgrade your browser.</video>
        <div class="poster hidden">

        </div>
    </div>

        $('.homepage-hero-module .video-container video').addClass('fadeIn animated');


    });
}

我已安装了现代化模块,并在我的sites / all / libraries / modernizr文件夹中包含了modernizr.min.js

我不确定,但您确保在sites/all/themes/THEME_NAME/js

内存储额外的js文件

因为Drupal不运行自定义js,除非它存储在那里需要的每个主题。

至少,你必须使用jquery命名空间包装javascript,如下所示:

(function ($) {
  Drupal.behaviors.myModuleBehavior = {
    attach: function (context, settings) {
      $('input.myCustomBehavior', context).once('myCustomBehavior', function () {
       // Apply the myCustomBehaviour effect to the elements only once.
      });
     }
  };
})(jQuery);

Drupal.behaviors.myModuleBehavior&#39;由于ajax的考虑,还有其他额外的代码。
