我正在尝试关注this因此我将以下代码(从子标题“步骤 2:将 JSX 添加到混合中”下方)直接复制到一个名为 index.html 的文件中，我在 chrome 中打开该文件:
<!DOCTYPE html>
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.14.6/react.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.14.6/react-dom.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.8.23/browser.js"></script>
</head>
<body>
<div id="app"></div>
<script type="text/babel">
// Code omitted to keep sample short
</script>
</body>
</html>
但是我在 chrome 控制台中收到此错误:
Uncaught DOMException: Failed to read the 'sessionStorage' property from 'Window': Access is denied for this document.

我不知道如何处理此错误或如何修复它。请注意，我没有对代码进行任何更改，我完全按照教程中的内容复制了它。感谢您的帮助。

您的浏览器似乎阻止了外部脚本对 sessionStorage 的访问。
