jQuery Ajax JSON错误解析

I have a JSON object that I was trying to send to a node server. I use this:

Generic function to make a request:

function makeTheRequest(method, url, data, dataType, onSuccess, onError, onComplete)
        method: method,//metodo|verbo con el que procesamos la peticion
        url: server + '/' + url,//url a la que hacemos la petición
        data: data,//datos del formulario
        dataType: dataType,
        success: onSuccess,
        error: onError,
        complete: onComplete

Concrete function where I call the generic:

jQuery('#sign_log_button').on('click', function()

    var user = {};
    var fields = true;
        else fields = false;
        makeTheRequest('POST', 'users', "user=" + user , 'json', onSuccessSignLog, onErrorSignLog);
    else alert("Please, check all fields.");

The problem I am finding is the same that many people has (I could read this problem on this forum, but no one answer is fixing me the problem... maybe I am not understanding well them).

Finally, I find a solution... and I think is great (becouse can support json and text request dataType on the server), but I would know how to do the json ajax request with jquery.

My Solution

(maybe is not the best... but it is mine, and I like it ;) ) Change the line where make the calling to the generic function for this other line:

makeTheRequest('POST', 'users', "user=" + JSON.stringify(user) , 'text', onSuccessSignLog, onErrorSignLog);

And on the server side this:

router.post('/', function(req, res)
    user = req.body.user;
    if(typeof user === "string") user = JSON.parse(user);

How I said, I think it is not bad becouse the server is more flexible, but I had been a long time trying to make a json ajax request... and I want to find the solution.

PS: My english is not the best... excuse me!!
