I need a table with selectable rows (there is a check box in every
row). All selected rows should be displayed with different style than
rows which are not selected.
I implemented this behavior by assigning the css-defined class to <tr>
tag
<tr id=<%="msgrow_#{m.id}"%>
class="unchecked_msg">
and toggling the class whenever checkbox is clicked.
<%= check_box_tag("checked_messages[]", object.id,
false, :class=>"selectable_msg", :align=>"top",
:onchange => "$
(''msgrow_#{object.id}'').toggleClassName(''checked_msg'',
''unchecked_msg'');") %>
It works fine until user refreshes page. After the refresh checkbox is
still checked, but the class of the row is reset to "unchecked_msg".
Anyone has an idea how to survive page refresh?
thanks,
Adam

only way: make an ajax call, whenever the checkbox is clicked. in the backend store the new value in the session or database and use this information to rebuild the whole page for a refresh --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
