html value of select option to jdo object
I'm doing an query and getting a list of albums names from my JDO, they are then displayed in a selection menu in html like this
List<NomeAlbum> results = (List<NomeAlbum>) query.execute(utilizador);
if (!results.isEmpty())
{
for (NomeAlbum e : results)
{
resultados = resultados + "<option value='"+results.get(i).nome+"'>"+results.get(i).nome+"</option>";
then printed in a selection option made in html
"</tr><tr><td>Escolha o album<select nam开发者_JS百科e='listaAlbums' id='listaAlbums'>" +
resultados +
"</select></td>"+
My problem is that I'm not getting the value of the selected option. For other fields I just do a iterator like this, but this doesn't work in here, i suspect its because it doesnt have any data printed, just a value:
if (item.getFieldName().equals("titulo")) {
byte[] buffer = new byte[8192];
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
int len = stream.read(buffer, 0, buffer.length);
outputStream.write(buffer, 0, len);
tituloparam = outputStream.toString();
Can someone help me how to save the value of the option selected? Thanks for your time
I didn't get what I was looking for, then I decided to do a workaround. I will try to explain the best I can cause maybe someone may have this doubt in the future.
Trough javascript I changed the value of an textarea whenever the select list it's changed.
<script type="text/javascript">
function album(selectValue,targetTextArea)
{
var txtNode=document.createTextNode(selectValue);
var textArea=document.getElementById(targetTextArea);
textArea.value = selectValue;
}
</script>
Then I just get the value of the textarea like i do for all other textareas like this
if (item.getFieldName().equals("textarea")) {
byte[] buffer = new byte[8192];
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
int len = stream.read(buffer, 0, buffer.length);
outputStream.write(buffer, 0, len);
tituloparam = outputStream.toString();
And there you go, I can get the value for my java class from the html select form. Probably there are better ways, but this was what i could arrange.
