How could pass the selected item in a select the URL

[wrb]

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

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

This is correct?

<script type="text/javascript">

google.load('visualization', '1.1', { 'packages': ['corechart'] });

google.setOnLoadCallback(drawChart);

function drawChart() {

var e = documento.getElementById("#animais");

var animais = e.opções[e.selectedIndex].valor;

var url = '/Programa_Nutricao/Avaliacao/EvolucaoPeso/' + animais;

That's not correct, object and property names are in English, not Portuguese.

var e = document.getElementById("#animais");

var animais = e.options[e.selectedIndex].value;
