how to display javascript window again when refreshing the page

I have a link on page click here.. when user click it , it open a javascript window, and he is doing some stuff there.. ( clicking on button , searching etc. all these happen in a window created by javascript )

But when i refresh the page , everything shuts down. All windows close. user have to click the link to open the window .

Is there a way to avoid this ?

Thanks

 

You can either make this a pop-up window

OR

Save whatever the person does in a cookie, and when the page refreshes, the server-side script reads the cookie and writes an onload function.

There are probably other solutions as well.
