如何修剪页面？
我有一个正在运行的 React 应用程序，我从外部 ASP.NET 应用程序获取页面。我只想获取页面的一部分而不是完整的页面。我不知道是否可以这样做。我的目标是只删除页面的主体。我的页面如下
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Privacy Policy - DotnetApp</title>
<link rel="stylesheet" href="/lib/bootstrap/dist/css/bootstrap.min.css" />
<link rel="stylesheet" href="/css/site.css" />
</head>
<body>
<header>
<nav class="navbar navbar-expand-sm navbar-toggleable-sm navbar-light bg-white border-bottom box-shadow mb-3">
<div class="container">
<a class="navbar-brand" href="/">DotnetApp</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target=".navbar-collapse" aria-controls="navbarSupportedContent"
aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="navbar-collapse collapse d-sm-inline-flex flex-sm-row-reverse">
<ul class="navbar-nav flex-grow-1">
<li class="nav-item">
<a class="nav-link text-dark" href="/">Home</a>
</li>
<li class="nav-item">
<a class="nav-link text-dark" href="/Home/Privacy">Privacy</a>
</li>
</ul>
</div>
</div>
</nav>
</header>
<div class="container">
<main role="main" class="pb-3">
<h1>Privacy Policy</h1>
<p>Use this page to detail your site's privacy policy.</p>
</main>
</div>
<footer class="border-top footer text-muted">
<div class="container">
© 2020 - DotnetApp - <a href="/Home/Privacy">Privacy</a>
</div>
</footer>
</body>
</html>

您可以使用 DOMParser 接口将 html 解析为 DOM 树。例如：let html = '<!DOCTYPE html><html><!-- some html --></html>' let doc = new DOMParser().parseFromString(html, 'text/html'); let bodyHtml = doc.body.innerHTML;
