Ajax Request

[eluser]Nutan Lade[/eluser]

Code:

function submitMovie(){
      alert("hi");
    var url = "<?=base_url()?>index.php/gadgets/addMovie";
        //alert(url);
        new Ajax.Request(url, {
        method:'post',
        parameters: {userId: 1},
        onSuccess: function(movieSubmit){
          var response = movieSubmit.responseText || "no response text";
          document.getElementById('movieSubmitMsg')[removed] = response;
         // alert("Success! \n\n" + response);
        },
        onFailure: function(){ alert('Something went wrong...') }
          });
  }

How can I get the parameters values on the server side.
