jquery jplayer cookie首选项

Question

好的，所以我有这个非常酷的Mario主题媒体播放器，由极其强大的jQuery插件jplayer的定制创建。

所以，我想给用户选择他或她是否想在网站的后台自动启动音乐播放。

我有它默认关闭的，因为这应该是一个企业，甚至是定期的，非盈利的网站，在背景音乐可以非常刺激性，尤其是如果它不清楚如何启动和停止音频。

无论如何，我试图设置一个cookie来做到这一点，使用直观的jQuery cookie plugin。

下面是代码我设置被点击的模式对话框的按钮时：

buttons: { 
    'Without Music': function() { 
    $(this).dialog('close'); 
    $.cookie('autoPlay', 'no', { expires: 365 * 10 }); 
    }, 
    'With Music': function() { 
    $(this).dialog('close'); 
    $.cookie('autoPlay', 'yes', { expires: 365 * 10 }); 
    } 
} 

现在，我正在一个蒂莫，这是检查每毫秒（是的，这很容易被调整，但我只是想即时结果），用于将autoPlay cookie的值，无论是yes或no！

setInterval(function() { 
    if ($.cookie('autoPlay') == no) { 
    displayPlayList(); 
    playListInit(false); // Parameter is a boolean for autoplay. 
    } 
}, 1); // checks every millisecond (i.e. 1/1000 of a second) 
    // need to do speed tests, and see if fast checking results in bogged down pages, difference between 1 millisecond and even 100-300 are nearly negligible 
setInterval(function() { 
    if ($.cookie('autoPlay') == yes) { 
    displayPlayList(); 
    playListInit(false); // Parameter is a boolean for autoplay. 
    } 

所以，出于某种原因，当我刷新页面，之后选择没错。播放器不会自动播放。现在，我认为这个问题可能是我的条件陈述的原因。但我不知道..

UPDATE：

这里是我的整个新jplayer.js文件，其中包括我们需要对这个问题的工作代码：

$(document).ready(function(){ 

    $("#jpId").jPlayer({ 
     swfPath: "/js" 
    }); 

    var playItem = 0; 

    var myPlayList = [ 
     {name:"SMB Overworld",mp3:"/audio/MushroomKingdomSMB.mp3"}, 
     {name:"SMB Underworld",mp3:"/audio/UnderworldSMB.mp3"}, 
     {name:"SMB Underwater",mp3:"/audio/UnderwaterSMB.mp3"}, 
     {name:"SMW Castle",mp3:"/audio/CastleSMW.mp3"} 
    ]; 

    // Local copy of jQuery selectors, for performance. 
    var jpPlayTime = $("#jplayer_play_time"); 
    var jpTotalTime = $("#jplayer_total_time"); 

    $("#jquery_jplayer").jPlayer({ 
     ready: function() { 
      displayPlayList(); 
      playListInit(false); // Parameter is a boolean for autoplay. 
     } 
    }) 
    .jPlayer("onProgressChange", function(loadPercent, playedPercentRelative, playedPercentAbsolute, playedTime, totalTime) { 
     jpPlayTime.text($.jPlayer.convertTime(playedTime)); 
     jpTotalTime.text($.jPlayer.convertTime(totalTime)); 
    }) 
    .jPlayer("onSoundComplete", function() { 
     playListNext(); 
    }); 

    $("#jplayer_previous").click(function() { 
     playListPrev(); 
     $(this).blur(); 
     return false; 
    }); 

    $("#jplayer_next").click(function() { 
     playListNext(); 
     $(this).blur(); 
     return false; 
    }); 

    function displayPlayList() { 
     $("#jplayer_playlist ul").empty(); 
     for (i=0; i < myPlayList.length; i++) { 
      var listItem = (i == myPlayList.length-1) ? "<li class='jplayer_playlist_item_last'>" : "<li>"; 
      listItem += "<a href='#' id='jplayer_playlist_item_"+i+"' tabindex='1'>"+ myPlayList[i].name +"</a></li>"; 
      $("#jplayer_playlist ul").append(listItem); 
      $("#jplayer_playlist_item_"+i).data("index", i).click(function() { 
       var index = $(this).data("index"); 
       if (playItem != index) { 
        playListChange(index); 
       } else { 
        $("#jquery_jplayer").jPlayer("play"); 
       } 
       $(this).blur(); 
       return false; 
      }); 
     } 
    } 

    function playListInit(autoplay) { 
     if(autoplay) { 
      playListChange(playItem); 
     } else { 
      playListConfig(playItem); 
     } 
    } 

    function playListConfig(index) { 
     $("#jplayer_playlist_item_"+playItem).removeClass("jplayer_playlist_current").parent().removeClass("jplayer_playlist_current"); 
     $("#jplayer_playlist_item_"+index).addClass("jplayer_playlist_current").parent().addClass("jplayer_playlist_current"); 
     playItem = index; 
     $("#jquery_jplayer").jPlayer("setFile", myPlayList[playItem].mp3, myPlayList[playItem].ogg); 
    } 

    function playListChange(index) { 
     playListConfig(index); 
     $("#jquery_jplayer").jPlayer("play"); 
    } 

    function playListNext() { 
     var index = (playItem+1 < myPlayList.length) ? playItem+1 : 0; 
     playListChange(index); 
    } 

    function playListPrev() { 
     var index = (playItem-1 >= 0) ? playItem-1 : myPlayList.length-1; 
     playListChange(index); 
    } 
    $('#text_music').click(function() { 
     $('#jplayer').slideToggle(500); 
    }); 

    $("#player").bind("clickoutside", function(event){ 
     if($('#jplayer').is(':visible')) { 
      $('#jplayer').slideToggle(500); 
     } 
    }); 

    setInterval(function() { 

     if($('a#jplayer_playlist_item_0').hasClass('jplayer_playlist_current')) {

它似乎仍然有同样的问题..我试图解决它，但如果您在我之前发现错误，请让我知道！ :)

Answer 1

，则需要比较到一个字符串，像这样：

if ($.cookie('autoPlay') == 'yes') { 

即使你检查yes，你仍然传递false另外，现在看来似乎应该是true。

我会了间隔50毫秒，至少，这样的整体：

setInterval(function() { 
    displayPlayList(); 
    playListInit($.cookie('autoPlay') === 'yes'); 
}, 1); 

虽然在一般，也不是检查在间隔一个cookie在所有，作出力所能及的执行效能的动作既设置cookie，然后执行操作...仅当使用 cookie时，首次在document.ready中设置播放器。
