刷新后返回

Question

I have a page with checking of a serial number (it doesn't matter). After checking number this page refreshes. I have a back button on the page and I need via this button go back to previous open page, not on page where I was when I tryed to check this number but the page which was before. When I use history.back() browser showes me error. How it can be written with jquery to work?

Answer 1

If I understood well, you want to go back two times in window history with that button in the refreshed page...
right?

If so.. then you need: window.history.go(-2)

History:

---------   ---------   ---------
|   1   |   |   2   |   |    3    |
| start |-->| check |-->|   page  |
|       |   |  snº  |   |refreshed|
|       |   |   &   |   |         |
|       |   |  page |   | button------
|       |   |refresh|   |         |  |
---------   ---------   -----------  |
