Re: [T5] Basic Ajax

[Borut Bolčina]

I am making some progress. I my AjaxBasic.tml file I have a <script> section
which has

var url = "ajaxbasic/" + encodeURIComponent(idField.value);

This idField gets from
<input type="text" id="userid" name="id" onkeyup="validate();"/>

In my AjaxBasic.java I have
public class AjaxBasic {

    private HttpServletRequest request;
    private HttpServletResponse response;

    @Inject
    private RequestGlobals _requestGlobals;

    private HashMap<String, String> users = new HashMap<String, String>();

    void pageLoaded() {
        System.out.println("AjaxBasic PageLoaded");
        users.put("greg", "account data");
        users.put("duke", "account data");
    }

    void onActivate(String id) throws IOException {
        request = _requestGlobals.getHTTPServletRequest();
        response = _requestGlobals.getHTTPServletResponse();
        System.out.println("AjaxBasic onActivate");
        System.out.println("id: " + id);
        if ((id != null) && users.containsKey(id.trim())) {
            response.setContentType("text/xml");
            response.setHeader("Cache-Control", "no-cache");
            response.getWriter().write("<message>valid</message>");
        } else {
            response.setContentType("text/xml");
            response.setHeader("Cache-Control", "no-cache");
            response.getWriter().write("<message>invalid</message>");
        }
    }
}

The problem is, that the response is not only the <message>valid</message>
or <message>invalid</message>

but the whole page's html is appended. How to prevent that?

Thanks,
Borut
