每次我在Google Chrome中加载MHT时，都会出现以下错误：

已阻止“”中的脚本执行file:///C:/...'因为文档的框架是沙盒，并且未设置'allow-scripts'权限

我知道
allow scripts
是
iframe
的
sandbox
属性的值，因此我无法将其值设置为
allow scripts
，因为顶部框架似乎是内部框架。当使用
file://
加载文件时，此内部框架仅添加
sandbox
属性是否有一种方法允许脚本在不使用http://的情况下运行？

我还试图在开发工具的设置中取消选中禁用JavaScript，但此复选框已变灰。

这似乎是一个已知的错误：

在具有此结构的mhtml文件的基础中：

MIME-Version: 1.0
Content-Type: multipart/related; boundary="----=_NextPart_EXSTREAMHTML"; type="text/html"

This is a multi-part message in MIME format.

------=_NextPart_EXSTREAMHTML
