Question

我的Jplayer是一个音频播放器，我遇到了一些麻烦。我无法访问isPaused。我需要做的是当玩家正在玩时，div的背景图像需要改变。我有两个测试脚本，都没有正常工作。

我的播放器

var myCirclePlayer = new CirclePlayer("#jquery_jplayer_1",
    {
        mp3: "/media/audio/RelaxSeg.mp3",
    }, {
        supplied: "mp3",
        cssSelectorAncestor: "#cp_container_1",
        swfPath: "/jQuery.jPlayer.2.2.0/v11/js",
        wmode: "window"
});

我的包装。

  <div id="jquery_jplayer_1" class="cp-jplayer"></div>
  <div id="cp_container_1" class="cp-container" style="background:none;">
    <img id="bg_image" class="bg_image1"  src="/jQuery.jPlayer.2.2.0/v11/circle.skin/jplayer_bg_img.png" height="60"  />
        <div class="cp-progress-holder"> <!-- .cp-gt50 only needed when progress is > than 50% -->
            <div class="cp-progress-1"></div>
            <div class="cp-progress-2"></div>
        </div>

    <div class="cp-circle-control"></div>
         <ul class="cp-controls">
             <li><a id="play1"  class="cp-play" tabindex="1">play</a></li>
             <li><a id="pause1"  class="cp-pause" style="display:none;" tabindex="1">pause</a></li> <!-- Needs the inline style here, or jQuery.show() uses display:inline instead of display:block -->
         </ul>


  </div>

这应该有效，但出于某种原因不行。

if($("#jquery_jplayer_1").data("jPlayer").status.isPlaying) { 
    $(".bg_image1").attr("src", "/jQuery.jPlayer.2.2.0/v11/circle.skin/jplayer_bg_image_green.png"); 
    } 
    else { 
    $(".bg_image1").attr("src", "/jQuery.jPlayer.2.2.0/v11/circle.skin/jplayer_bg_img.png");
    }

我也有这个代码可以正常工作，当玩家没有玩，没有显示暂停按钮，玩家正在玩时，它的风格变成display = block。

if(document.getElementById("pause1").style.display = "block") { 
    $(".bg_image1").attr("src", "/jQuery.jPlayer.2.2.0/v11/circle.skin/jplayer_bg_image_green.png"); 
    } 

if(document.getElementById("pause1").style.display = "none") { 
    $(".bg_image1").attr("src", "/jQuery.jPlayer.2.2.0/v11/circle.skin/jplayer_bg_img.png");
    }

我为代码块道歉，但我不想遗漏任何东西。

您可以通过以下操作挂钩jPlayer中的play，pause和end事件：

var myCirclePlayer = new CirclePlayer("#jquery_jplayer_1",
{
    mp3: "/media/audio/RelaxSeg.mp3",
}, {
    supplied: "mp3",
    cssSelectorAncestor: "#cp_container_1",
    swfPath: "/jQuery.jPlayer.2.2.0/v11/js",
    wmode: "window",
    play: function () {
        $(".bg_image1").attr("src", "/jQuery.jPlayer.2.2.0/v11/circle.skin/jplayer_bg_img.png");
    },
    pause: function () {
        $(".bg_image1").attr("src", "/jQuery.jPlayer.2.2.0/v11/circle.skin/jplayer_bg_image_green.png");
    },
    ended: function () {
        $(".bg_image1").attr("src", "/jQuery.jPlayer.2.2.0/v11/circle.skin/jplayer_bg_image_green.png");
    }
   });

jplayer暂停时改变背景
