How do I get the selected datepicker below and populate a label?

@Html.JQueryUI().Datepicker("data1", null, new { id = "data1", @class = "form-control" })

From a textbox with the date of birth as return label in ages in weeks, months and years.

How can I make the DropDownList appear only item from a particular id = Med_Produto?

Thank you! excellent.

I need to return 2 places after the comma:

How do I return with 2 places after the comma?

Thank you! excellent.

Yes, when the select has only one item.

See It. The graph is right, the URL this right. The problem is the event when the select receives a graphic value must render. In fact I do not know if the path is with the post code. Lack knowledge in JavaScript...

I changed the code because I did not find the error ... The "onchange" sends the value and renders the chart. The URL is correct, it is the place of animals I put 1 for example, the chart is rendered.

In the code below I need to select an item in the "select" the graphic is rendered, how could implement this?

@using (Html.BeginForm()){    @Html.AntiForgeryToken()    @Html.ValidationSummary(true)<select id="animais" name="cod_animal" class="form-control"></select><script type="text/javascript">        //google.load('visualization', '1.1', { 'packages': ['corechart'] });     //google.setOnLoadCallback(drawChart);    function drawChart() {              var frm = document.getElementById('#animais');        var animais = frm.options[frm.selectedIndex].value;                var url = '/Programa_Nutricao/Avaliacao/EvolucaoPeso/' + animais;        $.get(url, {},              function (data) {                  var tdata = new google.visualization.DataTable();                  tdata.addColumn('date', 'data_semanal');                  tdata.addColumn('number', 'peso_kg');                  for (var i = 0; i < data.length; i++) {                      if (data[i].data_semanal != null)                          tdata.addRow([ToJavaScriptDate(data[i].data_semanal), parseFloat(data[i].peso_kg)]);                  }                  var options = {                      title: 'Evolução do peso corporal',                      width: 700,                      height: 500,                      vAxis: { title: "PESO (kg)", minValue: 1, maxValue: 6 },                      hAxis: { title: "DATA", textStyle: { fontSize: 10 } },                      legend: { position: "none" }                  };                  var chart = new google.visualization.LineChart(document.getElementById('EvolucaoPeso'));                  chart.draw(tdata, options);              });    }</script> <div id="EvolucaoPeso" style="width: 900px; height: 500px;"></div>

No, how can I check?

rsrs.

This is correct?

How could pass the value of a selected item in a select in the url below to replace the 1:

var url = '/ Programa_Nutricao / Evaluation / EvolucaoPeso /' + 1;

Sorted out:

The error is on the line "var PrincipioID = $ (" # Formula_Existente ") val ();.." I select the item in the DropDownList id = "cod_Prod_Med_Formula" and return to "descricao" in the DropDownList id = "cod_Principio_Ativo". What should I change this code? What should I implement so that the words "'+ val [" id "] +'" returns with "cod_Principio_Ativo"?

Following classes:

 public partial class Prod_Med_Produto    {        public Prod_Med_Produto()                    public int id { get; set; }        public Nullable<int> cod_Prod_Med_Formula { get; set; }        public string nome_comercial { get; set; }               public Nullable<int> cod_Principio_Ativo { get; set; }                   public virtual Prod_Med_Principio_Ativo Prod_Med_Principio_Ativo { get; set; }        public virtual Prod_Med_Produto_Formula Prod_Med_Produto_Formula { get; set; }          } public partial class Prod_Med_Produto_Formula    {        public Prod_Med_Produto_Formula()        {                       this.Prod_Med_Produto = new HashSet<Prod_Med_Produto>();        }            public int id { get; set; }        public string formula { get; set; }        public Nullable<int> cod_Principio_Ativo { get; set; }                  public virtual Prod_Med_Principio_Ativo Prod_Med_Principio_Ativo { get; set; }        public virtual ICollection<Prod_Med_Produto> Prod_Med_Produto { get; set; }           }

Would anyone guide something for the error below?

"The required anti-forgery form field "__RequestVerificationToken" is not present."

The error occurs when trying to delete a row in the table on the button below:
