For example, the personal account query of China Guangfa Bank: the address is https://ebanks.cgbchina.com.c..., I think the do file behind this is a bit strange. If you Google it, it is a website made using the struts framework. .
And this website can disable the f12 developer tool. Pressing f12 will flash the self-developed developer tool developed by China Guangfa Bank and then disappear.
And this query seems to support browsers with IE core. Is this very embarrassing?
How to disable f12 and improve security?

Disable F12, use JS to bind keyboard events, and execute some events when the code is F12. Isn’t it OK? ? ?
