Difficulties in feeding a TextBox and a ComboBox with jQuery

I have no difficulty in passing any value from my View to my controller via jquery. Now the opposite can do nothing. I tried this way:

$('#meutextbox).val() = data.minha_result_da_controller.meu_campo; So nothing.

$('#meutextbox).text() = data.minha_result_da_controller.meu_campo; So nothing.

In this way, you will not see and still give Internal Server (500) error.

How do I feed my fields into the View, via jQuery with values coming from controller .

My jQuery code:

function CarregaDados(ajaxParameter) {

    var str = "";

    $.ajax({

        url: '/CadastroAcesso/CarregaDadosPagina',
        datatype: 'json',
        contentType: 'application/json;charset=utf-8',
        type: 'POST',
        data: JSON.stringify({ _nivel: ajaxParameter }),
        success: function (data) {

        },
        error: function (error) {
        }
    })
}

and my controller :

public JsonResult CarregaDadosPagina(int _nivel)
        {
            RupturaEntities db = new RupturaEntities();

            var result_carrega_pagina = db.Usuario
                .Where(n => n.IDUsuario == _nivel)
                .Select(s => new { s.NM_Usuario, s.Usuario1, s.Nivel_Acesso, s.Email }).ToList();

            return Json(new { result_carrega_pagina }, JsonRequestBehavior.AllowGet);
        }

This is the error you are giving:

POST http://localhost:53130/CadastroAcesso/CarregaDadosPagina 500 (Internal Server Error) jquery-2.1.0.js:8556send jquery-2.1.0.js:8556jQuery.extend.ajax jquery-2.1.0.js:8084CarregaDados CadastroAcesso.js:178(anonymous function) CadastroAcesso.js:171o.event.dispatch jquery-2.1.0.min.js:3r.handle

In this code:

.......
success: function (data) {

            $('#txtNome').val(data.result_carrega_pagina.NM_Usuario);

        },
        error: function (error) {
        }
........

Debugging my application, came this error:

I've been gone for a while now and came back to finish what I started. Still giving an error. It does not go into ajax success, on the contrary, it goes into the ajax Error function.

So that's it: I call dbclick and within that function, I call the function that will populate the textbox and combobox.

$('#nmUsuario').on("dblclick", '.clique', function () {
    CarregaDados($(this).parent().find(".idusuario").text());    
})

function CarregaDados(ajaxParameter) {

    var str = "";

    $.ajax({

        url: '/CadastroAcesso/CarregaDadosPagina',
        datatype: 'json',
        contentType: 'application/json;charset=utf-8',
        type: 'POST',
        data: JSON.stringify({ _nivel: ajaxParameter }),
        success: function (data) {

            alert(1);

            $('#txtNome').val(data.result_carrega_pagina.NM_Usuario);

        },
        error: function (error) {

            alert(2);
        }
    })
}

A question: If I send the parameter to execute lambda in my controller via data(JSON.stringify) , where do I get the result in jquery and ajax ?

This is the error you are giving:

The form must also be wrong, try this:

data: { _nivel: JSON.stringify(ajaxParameter) }

I also put the stringify off and sometimes no keys, thus leaving:

var jsonlist = JSON.stringify(json);

$.ajax({
    url: '/caminho/salvar',
    type: 'POST',
    cache: false,
    dataType: "json",
    data: {
        list: jsonlist
    },
    success: function (data) {
        alert('ok');
    },
    error: function (xhr, statusText, errorThrown) {
        alert('erro');
    }
});
