Difficulties in feedback 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 I get nothing. I tried so:

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

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

This way does not turn and still gives error: Internal Server(500).

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

My code jQuery:

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);
        }

That’s the mistake you’re making:

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 that code:

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

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

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

Debugging my application, came this error:

I’ve been away for a while and now I’ve come back to finish what I started. Still giving error. It does not enter the ajax success, on the contrary, it enters the ajax Error function.

So it’s all: I call dbclick and within this function, I call the function that will fill 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 run the lambda in mine controller via data(JSON.stringify), where I get the result then on jquery and ajax?

That’s the mistake you’re making:

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 jquery-2.1.0.min.js:3

Internal Server(500) Tell us you have an error on the server side, use your browser inspector to see what is being sent by jQuery and the server response. Debug your server-side code step by step to see where it is failing...

Only Alert(2) is being called.

The shape must also be wrong, try so:

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

I also put the stringify out and sometimes without 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');
    }
});
