jQuery run only once, even on back button press

Question

I have a page that loads an runs some jQuery. If I refresh the page, it's fine because it only runs the one time on a specific action. However, if the jQuery runs, then I go forward a page, and then back a page. The jQuery will run again because it is still loaded from last time. Is there something I can do that make jQuery only run once, even on a back button press?

Answer 1

您可以使用通过cookie / sessionStorage存储的状态，并基于cookie来确定是否再次运行它

Answer 2

Do you use jQuery Ajax? give it property -> cache: false
