Rails - Aug 2006 - Updating a database record using Javascript variables

I need to update a record in a table based on a event that occurs in the 
View. I believe the update action should occur in the controller.  I 
think I need to call the controller action from the View and pass data 
that is stored in a Javascript variables as a parameter, but I am not 
sure how to do it.  Can someone show me how I should be doing this?

Below is a simplified version of the code I am trying to produce:


View:
<script type="text/javascript">
<!--
function my_Func()
{
    varx  = dd.obj.x;
  // Not sure how to call the controller in the next line
    <%= render_component :action => ''updatex'', :xvalue
=> varx %>
}
-->
</script>

Controller:
Def updatex
    Person.update(10, {:xvalue => params[:xvalue]})
end
