jquery ajax post options to node.js request options

I use jQuery's ajax method in my node.js code. I would like to convert my jQuery ajax function's passed options to node's http module's request method options since now I want to use the request method instead. Is there a better way to do that than this ?

    function checkSetOption(param){
    if(param === undefined){
        return false;
    }else{
        return true;    
    }

} // End checkSetOption
//
var ajax = function(params,callBack){

    request_options = {};

    // Parse for http request params
    params = new Array('dataType','url','method','success');
    params.forEach(function(option,index,array){
        if(checkSetOption(option)){

            request_options.option = params.option;
        }
    }); // End 'forEach' method



    http.request(param);
};
