Can AJAX be used to achieve this effect?

Exist in cookie

GET these values in the background (whether GET or POST), then assign the assign to smarty, and finally obtain the next echo in the smarty template. Where are your doubts?
In addition, such data is not recommended for personal cookie or session

After passing parameters through the url, the backend obtains the parameters and the front-end determines the echo. We do not recommend storing cookies.
