下面是我的代码，它显示来自JSON变量的电影数据，并根据所选城市将其显示在下拉列表中。我需要显示节目时间以及JSON内容中的其他详细信息。
以下是我的代码：
$(document).ready(function() {
var cityData = [
{
cityName: 'Bengaluru',
value: 'Bengaluru',

movieName: 'ABC',
theaterName: 'Tulsi Theatre',

你的意思是这样吗？
我刚编辑了您的代码段。
$(document).ready(function() {
var cityData = [
{
cityName: 'Bengaluru',
value: 'Bengaluru',

$.each(locations, function(i, item) {

locationString2 +='<option value="' +item.movieName +'">' +item.movieName +'</option>';
$('#showTimings').html('');
$.each(locations[i].showTImings,function(i,v){
var button = $('<button />').html(v);

}
}

</div>
Movie: <span id="selectedMovie"></span>
</div>
</fieldset>
</div>
但是可以通过不重复相同的代码并将其移动到函数并调用它们来使其更简单。
答案 1 :(得分：0)
这是编辑过的代码
<div class="UserData">
...
<fieldset class="Container">
<legend class="selection">Your Selection</legend>
<div class="TmName">
Theater: <span id="selectedTheater"></span>
<div style="width: 30%;margin: 0 auto;" class="movieTimings">

<button class="btn1" id="movieTimeings"></button>

<button class="btn1" id="movieTimeings"></button>
</div>
Movie: <span id="selectedMovie"></span>
