[jQuery] Saving state of page wig Jquery

i spent about several days trying to figure out hot to save state of
open forms.

In my web page I have a jquery treeview tool, when I click form is
loaded into the #form div.

$(document).ready(function(){


  $('#treeview').click(function() {
    $('#form').load('../forms/inputdata.php');
  });


};

When i F5 - refresh page on browser div Form clears and treevew is set
to root.

I exepcteed treeview should stay open (on the node which i clicked)
and #form should have page loaded with inserted data ../forms/
inputdata.php

What should i do to treevew will stay open, page will stay in div and
data will be displayed on page?

thanks in advance
