document.getElementById('demo').value = selectText;

Remove the ID attribute from the aui:input tag

You need the portlet namespace. From the aui:input you will get a simple input field the ID of that input field will be the portletnamespace+yourAuiInputName

I think this script is on the jsp so this can work.

document.getElementById('<portlet:namespace />demo').value = selectText;

If this js is not on the jsp but in a separate js file. You have to pass the namespace in a parameter.

function js_alert(selected, namespace){

var selectText=selected.options[selected.selectedIndex].text;
alert(selectText);
document.getElementById(namespace+'demo').value = selectText;

}

<script>
   js_alert(selected, <portlet:namespace />);
</script>

Edit: Remove the ID field from the aui:input. That will be generated by the aui tag. In liferay 6.2 I had a lot of problem when I used the short endings. It would be better if you use the the aui tags like this:

<aui:input name="yourname" label="yourlLabel">
</aui:input>
