So sorry, everyone... hit submit by accident :(
continued....
<%= submit_tag %>
<% end %>
2. Create a jQuery script that loads the lat and lng values into the form
when the page loads. Something like:
jQuery(function(){
// JS code to get lat and lng from navigator object and set them into
hidden form field values
});
3. When the user submits the form, it will hit your controller with the
proper values and then redirect as you expect because it is a plain old
HTTP request, not an AJAX request.
Basically you are doing the same things as before, but with a regular HTTP
request
