I have a form with the fields below. I need to compare the year of the field select
with year of the date entered via JavaScript, and the year of the entered date must be identical to the year chosen, but not yet successful.
<label for="ano_licenca"><strong>ANO DA LICENCA</strong></label>
<select name="ano_licenca" id="ano_licenca" class="form-control">
<option value="">SELECIONE</option>
<option value="2017">2017</option>
<option value="2018">2018</option>
</select> <br><br>
<label for="data_emissao"><strong>DATA EMISSAO *</strong></label>
<input type="date" name="data_emissao" id="data_emissao" class="form-control" onblur="comparadataano()" autofocus/><br><br/>
<script type="text/javascript">
function comparadataano()
{
var ano_licenca = document.getElementById("ano_licenca");
var data_emissao = document.getElementById("data_emissao");
if (data_emissao.value > ano_licenca.value || data_emissao.value < ano_licenca.value) {
alert("ERRO! O ANO INFORMADO, NAO ESTAR COM O MESMO ANO DA DATA DE EMISSAO");
ano_licenca = document.getElementById('ano_licenca').value = '';
data_emissao = document.getElementById('data_emissao').value = '';
}
}
</script>
