问题描述：

答

https://ckeditor.com/docs/ckeditor5/latest/api/module_image_imageupload_imageuploadediting-ImageUploadEditing.html

这个api说可以加自定义属性，但是测试了无效。。。

用js处理下就可以了~用api内容太多就不研究了，getData还处理掉了xss一些非白名单属性，需要获取内容后再处理，不能直接处理ckeditor容器中的内容

<html lang="en">
<head>
	<meta charset="utf-8">
	<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0" />
	<link type="text/css" href="sample/css/sample.css" rel="stylesheet" media="screen" />
	<title>CKEditor 5 – classic editor build sample</title>
</head>
<body>
	<main>
			<div class="centered">
				<div id="editor" name="editor">
				
				<figure class="image">
				<img src="sample/img/umbrellas.jpg" alt="Three Monks walking on ancient temple.">

				<figcaption>Leaving your comfort zone might lead you to such beautiful sceneries like this one.</figcaption>
				</figure>

				<h3>Confidence</h3>

				<p>Going to a new place can be quite terrifying. While change and uncertainty makes us scared, traveling teaches us how ridiculous it is to be afraid of something before it happens. The moment you face your fear and see there was nothing to be afraid of, is the moment you discover bliss.</p>

			</div>
			<div style="text-align:center"><input type="submit" onclick="return addMoreAttr()" /></div>
		
	</main>


	<script src="ckeditor.js"></script>
	<script src="translations/zh-cn.js"></script>
	<script src="https://g.csdnimg.cn/??lib/jquery/1.12.4/jquery.min.js"></script>
	<script>
		function addMoreAttr() {
			var s = editor.getData();
			console.log(s)
			s = $('<div>' + s + '</div>').find('figure.image img').each(function () {
				$(this).addClass('progressive__img progressive--not-loaded').parent().addClass('progressive')
			}).end().html();
			console.log(s)
		}
		ClassicEditor
			.create(document.querySelector('#editor'), {
				language: 'zh-cn',
				ckfinder: {
					uploadUrl: '/home/upload'
				}
			})
			.then(editor => {
				window.editor = editor;

			})
			.catch(err => {
				console.error(err.stack);
			});
