javascript - jplayer 绑定(bind)似乎不起作用

Question

我继承了一个使用 jPlayer 的网络播放器。它对于播放音频文件效果很好，但我试图在用户播放轨道时设置一些隐藏字段，但我似乎无法在 jPlayer 中获得绑定(bind)到任何事件的内容。我已经使用类似的代码绑定(bind)到 h1 标签上的单击事件，它工作正常，但 jplayer 却不行。也没有错误。我从 jPlayer 的文档中获取了绑定(bind)示例。 这是我正在尝试做的事情的片段:

 $(document).ready(function () {

    //listener for playing the file
    $("#jquery_jplayer_1").bind($.jPlayer.event.play, function (event) {

        alert('play');
    });
 });

这是我的 html:

 <div id="jquery_jplayer_1" class="jp-jplayer"></div>

    <div id="jp_container_1" class="jp-audio" >
        <div class="jp-type-single">
            <div id="htmlPlayer" style="display: none">
                <audio id="audioPlayer" controls style="width:100%;">
                    <source id="mp3Source" type="audio/mp3" />
                </audio>
            </div>
            <div class="htmlHidePoint" style="display: none">
                <div class="jp-gui jp-interface">
                    <ul class="jp-controls">
                        <li><a href="javascript:;" onclick="javascript:alert('test');" class="jp-play" tabindex="1">play</a></li>
                        <li><a href="javascript:;" class="jp-pause" tabindex="1">pause</a></li>

                    </ul>
                    <div class="jp-progress">
                        <div class="jp-seek-bar">
                            <div class="jp-play-bar"></div>
                        </div>
                    </div>
                    <div class="jp-volume-bar">
                        <div class="jp-volume-bar-value"></div>
                    </div>
                    <div class="jp-time-holder">
                        <div class="jp-current-time"></div>
                        <div class="jp-duration"></div>

                        <ul class="jp-toggles">
                            <li><a href="javascript:;" class="jp-repeat" tabindex="1" title="repeat">repeat</a></li>
                            <li><a href="javascript:;" class="jp-repeat-off" tabindex="1" title="repeat off">repeat off</a></li>
                        </ul>
                    </div>
                </div>
            </div>
            <div class="jp-title">
                <ul>
                    <li><span id="songname">No Song Selected</span></li>
                </ul>
                <div class="under">
                    <ul>
                        <li><a href="#" onclick="ViewTranscript();return false;" onkeypress="ViewTranscript();return false;" tabindex="2">Transcript</a></li>
                        <li><a href="#" onclick="ViewDowloadOptions();return false;" onkeypress="ViewDowloadOptions();return false;" tabindex="2">Download</a></li>
                    </ul>
                </div>
            </div>
            <div class="htmlHidePoint" style="display: none">
                <div class="jp-no-solution">
                    <span>Update Required</span>
                    To play the media you will need to either update your browser to a recent version or update your <a href="http://get.adobe.com/flashplayer/" target="_blank">Flash plugin</a>.
                </div>
            </div>
        </div>
    </div>&nbsp;

实际的源文件是通过 jPlayer 方法中的错误选项加载的:

               error: function (event) {
                if (event.jPlayer.error.type == 'e_url_not_set') {
                    $(this).jPlayer("setMedia", {
                        mp3: '<%=ResolveUrl("~/Handlers/Podcasts.ashx") %>?command=ZipPodcast&PodcastID=' + selectedPodcast.ItemID + '&options=audio'
                    });

                    $(this).jPlayer("play");
                }
            },

Answer 1

显示 jPlayer 的 html。确保 ID 正确。

尝试在选项上指定它:

$("#jquery_jplayer_1").jPlayer({
  play: function() {
    alert('hi');
  }
});

您是在 jPlayer 使用您的选项初始化之前还是之后进行绑定(bind)？

绑定(bind)时jPlayer是否在页面上？
