I am not sure where I should post this since this seems to be an  
“interdisciplinary” problem

I am having trouble communicating between my javascript and my Rails  
app.

Here’s the snipped of code from my controller

* * *

def poll  
p params  
puts “Got here:”  
# debugger  
@some\_object = 12345  
respond\_to do |format|  
format.json { render :layout =\> false, :json =\> @some\_object }  
end  
end

* * *

I see

* * *

{“comment”=\>“ch”, “_method"=\>“PUT”, “action”=\>“poll”,  
“controller”=\>“reviews”, "_”=\>“1275680223825”}  
Got here:

* * *

in the Webrick console log

Here’s the relevant javascript:

* * *

pollWithAjax = function() {  
$.ajax(  
{  
// Define AJAX properties.  
type: “GET”,  
url: “/poll”,  
dataType: “script”,  
data: { \_method: ‘PUT’, “comment”: ‘ch’ },  
timeout: (10 \* 1000),  
beforeSend: function(xhr) {xhr.setRequestHeader(“Accept”,  
“application/json”)},

```
  // Define the succss method.
  success: function(){
    alert('pollWithAjax Success')
  },

  // Define the error method.
  error: function( objAJAXRequest, strError, errorThrown ){
    alert("pollWithAjax Error! Type: " + strError);
  }
}

```

);  
};

* * *

The “error:” function returns with the value of strError being “error”.

This is what FireBug says my headers look like

* * *

* * *

When I click on the response tab in Firebug, I see nothing.

Am I setting up the headers incorrectly?

## Now that you’ve shown us your code, please explain how the actual behavior of your app differs from what you want it to do. Best,

I would like a success return and the data returned.

The return is now taking the error return.
