In this way, a prompt will pop up when running in IE, whether to allow this kind of interaction. The mac address can only be obtained after confirmation.
In "Tools-->Internet Options--> Security -->Custom Level" " Initialize and script ActiveX controls that are not marked as executable safe scripts " is enabled, and there will be no prompts, but this is another There are security concerns. I don't know what better way to do it.
This method can only be used in IE, I don't know how to get it in other browsers.
