Record a piece of code that prevents web page saving - Midnight Guest
Today, while visiting a chat room login window, I found its graphic design to be very impressive and wanted to save it as an MHT file.
However, saving was disabled. So, Midnight Guest localized its source files and re-opened them locally to save. The following code was used to disable the "Save As" feature for the webpage:
```html
```
Note: The code uses a hidden iframe to interfere with the saving functionality, but this method is not foolproof and can still be bypassed by accessing the source files directly.
