Question

Hi I’m trying to do a foreach using a observableArray and I’m getting:

Uncaught Error: Unable to parse bindings.
Message: ReferenceError: Nome is not defined;
Bindings value: text: Nome 

Here’s my HTML:

<table data-bind="foreach: funcionarios">
    <tr>
        <p>Nome: <span data-bind="text: Nome"></span></p>
        <p>Apelido: <span data-bind="text: Apelido"></span></p>
        <p>Hobby: <span data-bind="text: Hobby"></span></p>
        <p>Função: <span data-bind="text: Funcao"></span></p>
        <p>Ramal: <span data-bind="text: Ramal"></span></p>
        <p>Email: <span data-bind="text: Email"></span></p>
        <p>Celular: <span data-bind="text: Celular"></span></p>
        <p>Aniversário: <span data-bind="text: Aniversario"></span></p>
    </tr>
</table>

Here’s my Js:

var FuncionarioViewModel = function () {
    var me = this;

    function Funcionario(base, id, nome, apelido, hobby, funcao, ramal, email, celular, aniversario) {
        var me = this;

        me.Id = id;
        me.Nome = ko.observable(nome);
        me.Apelido = ko.observable(apelido);
        me.Hobby = ko.observable(hobby);
        me.Funcao = ko.observable(funcao);
        me.Ramal = ko.observable(ramal);
        me.Email = ko.observable(email);
        me.Celular = ko.observable(celular);
        me.Aniversario = ko.observable(aniversario);
    };

    me.funcionarios = ko.observableArray([]);

    me.add = function (id, nome, apelido, hobby, funcao, ramal, email, celular, aniversario) {
       me.funcionarios.push(new Funcionario(me, id, nome, apelido, hobby, funcao, ramal, email, celular, aniversario));
    };
}

var viewModel = new FuncionarioViewModel();
ko.applyBindings(viewModel);

And here’s the Fiddle link: http://jsfiddle.net/Lrqeb/8/

I’m not want to load page with default data in that array.

EDIT:

Ok, just checked your jsfiddle. I updated to use the if binding to check if the array contains any elements before trying the foreach which will stop the binding error:

I wrapped your foreach with the following:

<div data-bind="if: funcionarios().length > 0">

EDIT2:

Also, you’ve applied the foreach to the table tag which won’t work. I changed it to use the tbody tag instead and that works fine here: http://jsfiddle.net/Lrqeb/10/

The changes look like this:

<div data-bind="text: funcionarios().length"></div>
<div data-bind="if: funcionarios().length > 0">
<table>
    <tbody data-bind="foreach: funcionarios">
    <tr>
        <td>Nome: <span data-bind="text: Nome"></span></td>
        <td>Nome: <span data-bind="text: Apelido"></span></td>
        <!-- and so on... -->
    </tr>
   </tbody>
