Hi
You need to change the target attrubute of the form tag. Give it an id
if it doesn't have one:
form_tag({:action =>"update"}, {:id => "the_form"}) do
...
Then if using prototype, $('the_form').target += '&varname='+var;
Mind you URL encode the params value. You can use the escapeHTML
string class to encode it properly if using prototype. I think there
is also an escape function ;)
