我有三个带有选择小部件的标签；选择一个项目会填充下面 div 的内容。在这三种情况中的两种情况下，一切都很好；但是，在第三个中，下拉菜单消失了。内容布局的不同之处在于，在第三种情况下（“坏”一种，下拉菜单消失），内容没有那么宽。
这是一个好的样子：
这是失败的样子（你应该看到在下拉列表中选择了“乡村音乐奖”）：
它们的代码都是相同的：动态创建 HTML，然后将其分配给内容区域：
$('#MoviesContent').html(htmlBuilder);
. . .
$('#MusicContent').html(htmlBuilder);
那么，为什么其他人会认为选择小部件的踩踏场地是不可侵犯的，而音乐部分则用土鸡踩踏花坛呢？
更新
应大众需求，以下是相关代码：
jQuery
$('#musicDropDown').change(function () {
var sel = this.value;
. . .
else if ((sel == "CMA") && (currentMusicSelection != "CMA")) {
currentMusicSelection = "CMA";
getCMA();
}
. . .
}); //musicDropDown
function getCMA() {
var htmlBuilder = '';
$.getJSON('Content/cma.json', function (data) {
$.each(data, function (i, dataPoint) {
if (IsYear(dataPoint.category)) {
htmlBuilder += '<div class=\"yearBanner\">' + dataPoint.category + '</div>';
} else {
htmlBuilder += '<section class=\"wrapper\" ><a id=\"mainImage\" class=\"floatLeft\" href=\"' +
dataPoint.imghref +
'<div id=\"prizeCategory\" class=\"category\">' +
dataPoint.category +
'</div><br/><cite id=\"prizeTitle\" >' +
dataPoint.title +
'</cite><br/><div id=\"prizeArtist\" class=\"artist\">' + dataPoint.artist + '</div><br/>';
if (dataPoint.mp3.trim().length > 2) {
htmlBuilder += '<button><a href=\"' + Urlify(dataPoint.mp3) + '\"' +
' target=\"_blank\" >mp3</a></button>';
}
if (dataPoint.cd.trim().length > 2) {
htmlBuilder += '<button><a href=\"' + Urlify(dataPoint.cd) + '\"' +
' target=\"_blank\" >CD</a></button>';
}
if (dataPoint.vinyl.trim().length > 2) {
htmlBuilder += '<button><a href=\"' + Urlify(dataPoint.vinyl) + '\"' +
' target=\"_blank\" >Vinyl</a></button>';
}
htmlBuilder += '</section>';
}
}); //each
$('#MusicContent').html(htmlBuilder).
find('img, button').click(function (evt) {
$(this).css('border', '1px solid gold')
});
$('#MusicContent').css('background-color', 'black');
$('button').button();
}); //getCMA
$largest = 0;
$(".wrapper").each(function () {
if ($(this).height() > $largest) {
$largest = $(this).height();
}
});
$(".wrapper").css("height", $largest);
}
