Question

关于此页面上的音频：http://ebonytay.com/site/composer.php?clip=getOutOfTown#mediaplayer

音频控件显示在Chrome和Safari（以及本地的Firefox中。我遇到了特定的实时服务器工作的问题，但这无关紧要）。但是，在IE9中，音频控件是不可见的。音乐仍然在播放，如果你右键点击它所假设的位置，你可以播放/暂停它，它只是没有出现。

我试过搞乱z-index。我试过把它放在所有的div之外。我尝试过使用src =而不是source。我尝试使用控件而不是controls =“controls”。我已经尝试使用音频标签直接获取文件，没有任何PHP / Javascripting。我对编程很新，所以我确信一些代码可以写得更简单，但它不应该破坏任何东西。任何帮助将不胜感激。

以下是页面上音频播放器（不包括css）的所有代码：

<?php 
  $song = "overtureRedRockRise"; // set to starting song
  $autoplay = ""; // disable autoplay on page load
  $totalSlides = 1; //default amount of slides
  $initialSlide = 1; //default starting slide

  // Change song to URL parameter defined by links in #clip_nav div
  if (isset($_GET["clip"])) // if URL parameter is ?clip=foo
  { 
    $song = $_GET["clip"]; // $song is foo
    $autoplay = "autoplay='autoplay'"; // enable autoplay when changing song
  } 

  // Check how many slideshow images exist for current song
  while (file_exists("../audio/filmClip_" . $song . "_" . $totalSlides . ".jpg"))
  {
    $totalSlides++;
  }
  $totalSlides--; // subtract 1 to get total number of slides for current song
  ?>

  <script>
  $(document).ready(function() {

        var currentSlide = 1; //default starting slide
        var totalSlides; //number of slides for current song
        var song; //current song
        var slideSpeed; //current slideshow speed

        // Get variables from PHP
        totalSlides = <?php echo $totalSlides ?>;
        song = "<?php echo $song ?>";

        // Setup slideshow speeds in milliseconds using JSON
        var songSpeed = 
        [
            ['overtureRedRockRise',12000],
            ['getOutOfTown',7000],
            ['canyonBaby', 5000],
            ['celestialGuides', 10000],
            ['springback', 11000],
            ['hallelujas', 10000],
            ['myOnly', 8000],
            ['selfDefense', 10000],
            ['orchestral', 10000]
        ]

        //go through each song in array
        for (i = 0; i < 9; i++)
        {
            //find the current song
            if (song == songSpeed[i][0])
            {
                //set current slideshow speed
                slideSpeed = songSpeed[i][1] + 1000; //add 1 second for loading time
            }
        }

        // Setup slideshow
        function changeSlide()
        {
            // change current slide number
            currentSlide++;

            // Loop slideshow
            if (currentSlide > totalSlides) { currentSlide = 1; }

            // Display current slide
            $('.song_image').attr('src', '../audio/filmClip_' + song + '_' + currentSlide + '.jpg');
        }   

        // If song has more than 1 image
        if (totalSlides > 1)
        {
            // Play slideshow
            setInterval(changeSlide, slideSpeed);       
        }

        // Indicate current song
        $('div.filmClip_list.'+song).addClass('currentSong');
    });
    </script>

Answer 1

这是style_2011.css中的规则：

body.composer audio {
    height: 32px;
    width: 100%;
}

具体来说，如果您将高度设置为45px或更高，则会出现控件。

Answer 2

只需移除音频标签的高度即可。
