<aui:form action="" method="post" onsubmit="" name="fm1">

Hi Sofia,

If you have something like below:
<aui:form action="" method="post" onSubmit="" name="fm1">
.......
<aui:select inlineField="true" inlineLabel="right" label="" name="portletType" id="portlet-type">
<aui:option value="Other" selected="true">Other</aui:option>
<aui:option value="Highlights" >Highlights</aui:option>
</aui:select/>
.. ....
</aui:form>

You can fetch its value in class like below after form submit:

String portletType = ParamUtil.getString(aActionRequest, "portletType");

Is that what you require or something else?

HTH!

Hi , thank you for replying so soon.

I need to get the value of the select chosen every time it's changed ..
the Id of the select can I change it or i should use the same as u said

thanks

Hi ,

You can go with above approach as I mentioned. Id should not be changed. You get selected value in your java class as above.

HTH!

Ok I use exactly what you posted :

  <aui:form action="" method="post" onsubmit="" name="fm1">
   <aui:select inlinefield="true" inlinelabel="left" label="Test" name="portletType" id="portlet-type">
    <aui:option label="-- Choice  --" value="0" selected="true" />
    <aui:option label="1" value="1" />
    <aui:option label="2" value="2" />
    </aui:select>
  </aui:form>
  <span>&lt;%=ParamUtil.getString(request, "portletType")%&gt;</span>

and It returns nothing the span is empty !

thank you..

Hi,

You want this value in java class or jsp where you are creating this aui:select ?
After form submit you shall get selected option value in your processAction of Java class.

thank you

Hi,

On server side as I mentioned, you can do : String portletType = ParamUtil.getString(aActionRequest, "portletType");

On client side for onchange event, you can get via javascript:

A.one("#<portlet:namespace/>portlet-type").on("change", function(){
alert(this.val();
)};

HTH!
