javascript event when you hit 'back' onto the page? [duplicate]

This question already has answers here: 开发者_JAVA百科 Is there a cross-browser onload event when clicking the back button? (15 answers) Closed 9 years ago.

What event can i use to run code when a user visits another page then hits back to load my page again?

I wrote window.onload = function() { ... and it works when i hit refresh but not forward then back.
