How to Stay on the Current Page When Switching Languages?

[yanglbme]

I have a website https://doocs.github.io/leetcode that provides both Chinese and English versions. I want to achieve the effect of staying on the current page when switching languages, instead of redirecting to the root directory of the selected language. How can I implement this?

I developed a simple custom hook plugin, stay_on_page.py, to implement this functionality and would like to share the approach with you all:

Here is the source code: https://github.com/doocs/leetcode/blob/docs/hooks/stay_on_page.py
