<%= link_to 'Change #Rows per Page', {:action => 'set_row_per_page', :rowsperpage => <would like to pass here the content of "numrows" >, :method => :post, :class => "IsALink" %>
Note that "numrows" is a non-model field of the form.
How can i dynamically set the value of ":rowsperpage" so that clicking on the link will restart pagination with a differente number of rows per page. I need to know how to dynamically set up the value of the parameter using something link $('numrows').value
I can't think of any way to do this with link_to. Remember that link_to is a server-side helper method that's generating an html <a ...> tag to send to the client. There might be a way to use client-side javascript to modify the tag, but it doesn't feel like a Rails-ish approach to me.
If it were me, I'd ditch the link-based submission and just use observe_field on the text_field or drop-down (select) to trigger the repagination action.
