ruby on rails return json to ajax

[fang]

how i  define my controller :
       def show
         @user=User.find(params[:id])
        respond_to do |format|
          format.json { render json: @user.to_json, :only => [:name, :email]}
        end
       end
how i define my ajax function:
  function FunAjax()
        {
            $.ajax({
                type: "POST",
                url: "http://ip:3000/users/1.json",
                data: "begin=1&end=9",
                dataType: "json",
                timeout : '50000',
                error : function(){
                    alert ('server error');
                },
                beforeSend: function(){
                    $("#span_content").text("processing...");
                },
                success:function(data){
                    if(data === null){
                        alert('no data');
                    }else{
                        var div_cont ="";
                        $.each(data,function(idx,arr_item){
                            div_cont = div_cont +"<br/>key："+idx+"value："+ arr_item;
                        }),
                        $("#span_content").html(div_cont);          
                    }
                     
                }
            });
        };
    $(document).ready(function () {
        alert('start');
    });

then i browse the url:http://ip:3000/users/1.json
it will return a string like this:
{"name":"fang","email":"fa...@fang.com"}
but the ajax function won`t work.
please tell me how can i exchange data between the server and the browser?

SMH. What does that mean? What's in your log? in your JavaScript 

console?

And why are you POSTing a request to a method that typically would

be accessed via GET, as in your browser (which apparently works)?
