Alguem sabe como eu pego o valor do <h:selectonemenu> com javascript?
Eu tentei com os codigos abaixo e nao obtive sucesso:
document.getElementbyId('idcombo').value
e tbm tentei:
document.nomeform.idcombo.value
Eu procurei em mtos lugares e nada.
Se alguem puder me ajudar.
Grato
como está o id do select?
Para "pegar " algum valor atraves de java script voce deve setar um id, exe.:
<input type="text" id="input">
e para pegar os dados:
document.getElementById("nomeIput").value;
em select voce tem que chamar o uma função javascript em onChange passando o valor this, e na função sim pegar o o valor que foi passado atraves do documente.getElementeBy… ex.:
<select id="nomeSelect" onChange="funcao(this)"></select>
Abraços!
Opa!
Obrigado por responder!

lembrando que os ids em JSF são setados sempre como o nome do form:id do componente
então se o form se chamar formulario e o componente chamar combo o valor deverá ser recuperado da seguinte maneira
document.getElementById('formulario:combo').value;
[]s
Sim mas olha só, você esta chamdno a função atraves de um botão, você terá de chama a funçatravés de um onChange ou algo parecido, jstl não me recordo exatamente o comando
Abraço!
Opa!
Funcionou!
Veja a função:
function verificaHorario(){
var valor = document.getElementById("alocaform:horainicio").value;
alert(valor);
}
Obrigado pela ajuda!
