我正在尝试向我的 html 页面添加模态，但关闭按钮似乎有问题

>我在网页中制作了一个模式，当我单击时它会显示，但是当我单击关闭时，没有任何反应(它没有关闭(任何想法？

function voice() {
$("#myModal").modal('show');
$('.try').css("opacity", "0.3");
}
function closeModal() {
$("#myModal").modal('hide');
$('.try').css("opacity", "1");
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
<a class="boxed-btn3 " onclick="voice()">----- Try -----</a>
<div id="myModal" class="modal fade" tabindex="-1" style="opacity:1;">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h3 class="modal-title">Try saying something...</h3>
<button type="button" class="close" data-dismiss="modal" onclick="closeModal()">&times;</button>
</div>
<div class="modal-body">
<i class="fas fa-microphone"></i>
<button class="button button5"></button>
</div>
</div>
</div>
</div>

我通过更改它解决了它

<div id="myModal" class="modal fade" tabindex="-1" style="opacity:1;">

对此

<div id="myModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" data-backdrop="false">
