我已经使用 jQuery 用 XML 数据填充了一个选择元素，这并不难。我现在正试图找到一种方法，在其自己的单独 div 区域中显示分配给该选择元素中特定元素的信息。到目前为止，这是我的代码示例：

    $('.selectspeak').live('change', function() {

                $("#mainOutput").empty();

                $(g_playDOM).find("SPEECH").each(function(){

                    var speaker = $(".selectspeak").val();
                    var line = $(this).find("LINE").text();

                $("#mainOutput").append("<div class='speakerClass'>" + "Speaker: " + speaker + "<br />" + " <div class='speakerClassLine'>" + "<br />" + "Line: " + line + "</div>");

            });

});

上面的代码本质上是用说话者数据填充选择标签，没问题。但是在选择扬声器时，它只显示正常的数据，而不是分配给扬声器的数据。如何确保在选择扬声器时仅显示指定的信息？

我已经尝试破解这个坚果几个小时了，进展甚微，所以朝着正确的方向轻推会很棒！:-)

谢谢！

更新：我添加了一个指向实时项目的链接。只需在左侧选择一个播放，然后您将能够在右侧看到我正在谈论的选择元素。谢谢。

我认为您必须过滤选定的“语音”项目。

$('.selectspeak').live('change', function() {

                $("#mainOutput").empty();

                $(g_playDOM).find("SPEECH").each(function(){

                    var speaker = $(".selectspeak").val();
                    //I'm checking if this 'SPEECH' is by "SPEAKER"
                    if($(this).find("SPEAKER").text()==speaker){


                    var line = $(this).find("LINE").text();
                    $("#mainOutput").append("<div class='speakerClass'>" + "Speaker: " + speaker + "<br />" + " <div class='speakerClassLine'>" + "<br />" + "Line: " + line + "</div>");
                    }



            });

});​

在这里，我检查了所选的“SPEECH”项目是否属于“Speaker”。
