我正在测试 bootstrap 和 jQuery 是否可以正常工作，但 jQuery 对话框的 X 按钮没有显示。
我认为这与标签顺序有关。
这是我的代码:
$(function () {
$("#dialog").dialog();
});<!DOCTYPE html>

要实现此对话框，您需要在代码中添加jQueryUI CSS
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Document</title>
<link href="https://fonts.googleapis.com/css?family=Roboto&display=swap" rel="stylesheet">
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
<link rel="stylesheet" href="https://code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
</head>
<body>
<div id="dialog" title="Basic dialog">
<p>This is the default dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.</p>
</div>

<script>
$( function() {
$( "#dialog" ).dialog();
} );
</script>
