I have a ZF form with 2 select boxes. Both should fill from 2 DB tables. First select box will be filled when the form get rendered at first. (So this is done and working fine)
Then I want to fill the second select box by taking the value of the first select box when a value is selected by the user and pass it to the select SQL to get the second set of data.

And I don't want the page to be refreshed. (So ajax/javascript/jquery)

I have following in my view (.phtml)

```
<script type="text/javascript">

$(document).ready(function(){
$('#make').change(function($e){
    $e.preventDefault();
     var href= "index/load";
     var data = 'make_id='+$('#make').val();
     $.ajax({ type: "POST",
           url: href,
          data: data,
          success: function(response){
            location.href = 'index/load';
         }
     });
});
});

</script>

```

but I cannot access the value passed from the ajax post using following in my controller action

```
$this->getRequest()->getParams('make_id');

```
