in firefox and ie11 worked fine but in chrome given some flashes of page load for set the scroll position of previous any solution for avoid these flashes

I am just kicking tyres and noticed the following on Chrome (latest Mac)

What happens
I'm on Page A and 500px down the page.
It's this position on Page A to which I wish to return.
However, when I click into Page B from Page A, I end up 500px down the page by default.

So far this thing does nothing?

Thanks for the nice utility! With my appreciation, here are possible improvement ideas, FYI:

• Use of window.addEventListener('pagehide', ... ) instead of window.onbeforeunload =
  Use of beforeunload event "prevents browsers from using in-memory page navigation caches", whreas pagehide doesn't and its timing works fine for the purpose.
  Also, usage of window.addEventListener() is safer than directly assigning the handler.
• By using '[' (no leading space) instead of ' [' in Line 10, and change Line 14 to if(window.name.indexOf('[') >= 0) you can get rid of the use of $.trim() in Line 17, which makes the code a bit simpler.
• By using window.pageXOffset, window.pageYOffset in Line 10 together with the above, I think it is ready for un-jquery-fication.

Hope this helps!
