Rails - Jul 2009 - Problem with RJS

Hi,

I am trying to do a rails application that uses google map to allow
users to specify longitude and latitude and then the google map should
be updated to show that location which was specified.

I am using observe_field on the text field like this:

        <%= observe_field ''geo_loc_cords'',
        :url => {:action => :update_map, :form_authenticity_token =>
form_authenticity_token},
        :update => :map,
        :with => ''"cords="+element.value'',
        :loading => "Element.show(''spinner'')",
        :complete => "Element.hide(''spinner'')"
%>

and my map div looks like this:

<%= @map.div(:width => 400, :height => 300) %>

and in the update_map action I have this (hardcoded the coordinates for
now):

  def update_map()
    latitude = 43.023849
    longitude = -77.682053
    @map = Variable.new("map")

    point = GLatLng.new([latitude, longitude])
    @marker = GMarker.new(point, {:title => "Site:", :info_window
=>
"Site:",
                        :draggable => true})
    respond_to do |format|
      format.html
      format.js
    end
  end

And my rjs template simply looks like this:

page << @map.clear_overlays
page << @map.add_overlay(@marker)

Yet the result is simply outputted on the page as:

try { map.clearOverlays(); map.addOverlay(addInfoWindowToMarker(new
GMarker(new GLatLng(43.023849,-77.682053),{title : "Site:",draggable :
true}),"Site:",{})); } catch (e) { alert(''RJS
error:\n\n'' +
e.toString());
alert(''map.clearOverlays();\nmap.addOverlay(addInfoWindowToMarker(new
GMarker(new GLatLng(43.023849,-77.682053),{title : \"Site:\",draggable
:
true}),\"Site:\",{}));''); throw e }

What am I doing wrong to make the resulting javascript outputted on the
page rather than interpreted as javascript?

Solved it, just needed to remove the :update => :map in observe field.
