Ruby on Rails

Hello all,

I'm trying to write a jquery function where I am posting some data from a form. I am wondering is there a way to select the particular param that I want to use when I submit the data to $.ajax(). I don't believe it makes sense to create a hidden field just to use with $.ajax() but I can't seem to figure out how to get to the params key/value using jquery.

The code that I am attempting to use is:

$.ajax({

url: "/app/controller/action",

type: "POST",

data: {code : 'param[:value]' or ??}

});

Can this be done at all? if so, what would be a good approach?

Thanks,

-

 var form = $('#new_form');
   $.ajax({
     url: form.attr("action"), 
     type: "POST",    
     data: form.serialize(), 
     cache: false,
     beforeSend: function(){
        //something here
     },
     complete: function(){
        // something here
     },
     success: function (result) {

         //here comes whatever you want      

     }
