我尝试删除和添加内容，但下拉菜单仍然不会下降。我不确定问题是什么。我添加了较少的文件，其中包括下拉列表，但仍然没有任何改变。不过文本框正在工作。代码如下所示
<html>
<head><link rel="stylesheet" type="text/css" media="screen"
href="css/datepicker3.css">
<link rel="stylesheet" href="css/bootstrap.min.css">
<link rel="stylesheet/less" href="less/dropdowns.less">
<link rel="stylesheet/less" href="less/sprites.less">
</head>
<body>
<div class="input-group date" data-date-format="dd-mm-yyyy">
<input type="text" class="form-control" name="date"><span class="input-group-addon"><i class="glyphicon glyphicon-th"></i></span>
</div>
<script type="text/javascript">
$('.input-group.date').datepicker({
changeMonth: true;
changeYear: true;
});
</script>
<script type="text/javascript"
src="js/jquery-1.11.2.min.js">
</script>
</script>
<script type="text/javascript"
src="js/bootstrap.js">
</script>
<script type="text/javascript"
src="js/bootstrap.min.js">
</script>
<script type="text/javascript"
src="js/bootstrap-datepicker.js">
</script>
<script type="text/javascript"
src="js/bootstrap-datepicker.en-GB.js">
</script>
</body>
</html>
最佳答案
您自定义的 javascript 方法将在 jquery 和 bootstrap.js 加载之前执行。仅当其库类在您的方法执行之前加载时，您的自定义方法才会起作用。因此，您的代码必须如下所示:
<html>
<head><link rel="stylesheet" type="text/css" media="screen"
href="css/datepicker3.css">
<link rel="stylesheet" href="css/bootstrap.min.css">
<link rel="stylesheet/less" href="less/dropdowns.less">
<link rel="stylesheet/less" href="less/sprites.less">
</head>
<body>
<div class="input-group date" data-date-format="dd-mm-yyyy">
<input type="text" class="form-control" name="date"><span class="input-group-addon"><i class="glyphicon glyphicon-th"></i></span>
</div>
<script type="text/javascript"
src="js/jquery-1.11.2.min.js">
</script>
</script>
<script type="text/javascript"
src="js/bootstrap.min.js">
</script>
<script type="text/javascript"
src="js/bootstrap-datepicker.js">
</script>
<script type="text/javascript"
src="js/bootstrap-datepicker.en-GB.js">
</script>
<script type="text/javascript">
$('document').ready(function(){
$('.input-group.date').datepicker({
changeMonth: true,
changeYear: true,
});
});
</script>
</body>
</html>
$('.input-group.date').datepicker({changeMonth: true,
changeYear: true});<!DOCTYPE html>

</html>也没有“;”但是日期选择器选项中的“，”，
正如 @Sachi Tekina 所说，无需加载 Bootstrap 两次。
关于javascript - Bootstrap 日期选择器下拉菜单不下降，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/28623041/
