[Ajax in Java] v IE6 dela, v Firefoxu ne

Torej, delam eno formo v jsp-ju in pač bi rad naredil en enostaven autocomplete. V IE dela super, v FF pa se ne zgodi nič. kakšna ideja?

Aja, valda mam kreiranje request objekta ločeno za FF in IE posebej (XmlHttpRequest in ActiveObject...).

to ti je pa microsoftova tehnologija...

Servlet pa po logiki takle:

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class AjaxResponseServlet extends HttpServlet {

private static final long serialVersionUID = 1L;

public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {

String key = req.getParameter("key");
if (key != null && key.equalsIgnoreCase("L") ) {
// extract the first character from key
// setup the response
key = "LJU";
}
res.setContentType("text/xml");
res.setHeader("Cache-Control", "no-cache");
// write out the response string
res.getWriter().write(key);

}
}

Ne, v RAD-u (IBM Rational Application Developer, java server je torej Websphere, ampak to najbrž nima veze).

Nisem opazu nobene napake, ne v js, ne v java kodi. A lahko ugotoviš če se v firefoxu sploh sproži request?

Poizkusi namesto req.send(null); uporabiti req.send(''); - se mi zdi, da sem imel isti problem s Firefoxom (med tem, ko je v Operi delalo).

Poskusi z Firebugom postaviti breakpointe v js. Boš hitro ugotovil kje je napaka.

To kar si ti napisal, bi vsekakor moralo delovat. A imaš še kak JS na isti strani?

var busy = false;
function submitSearch(form)
{
//set the result catEntryType, which is checked on CatalogSearchResultDisplay.jsp:
// 1 = list items, packages, and bundles
// 2 = list products, packages, and bundles

if (!busy)
{
busy = true;

form.searchTerm.value = form.searchTerm.value.replace(/^\s+/g, '').replace(/\s+$/g, '');

form.minPrice.value = form.minPrice.value.replace(/^\s+/g, '').replace(/\s+$/g, '');
form.maxPrice.value = form.maxPrice.value.replace(/^\s+/g, '').replace(/\s+$/g, '');


if ((form.minPrice.value == "") && (form.maxPrice.value == ""))
{
form.resultCatEntryType.value = "2";
form.currency.value="";
}
else
{
form.resultCatEntryType.value = "1";
}

form.submit();
}
}

OK, po malo daljšem trejsanju sem ugotovil, da je problem vsaj tule, če ne še kje:

document.getElementById("textfield")

namre, to ne vrne ničesar, zato je "key" polje prazno. Kdo ve, zakaj? V IE se polje lepo napolni...

Ja, itak.

No, polje je v glavnem "undefined". A mogoče v FF ta metoda (getElementByID) ne dela?

MATER! Bemo! Jebenti! Pismo, no!!!

Pozabu sem en klinčev narekovaj v id atributu (html). IE to očitno tolerira, FF pa ne. AAARRGGGH!!!

Vseeno vsem najlepša hvala! Sej v bistvu breu vas niti najdu ne bi, ker sem bil zihr, da je ok, pa sem vseeno na nagovarjanje obeh še enkrat pogledal.

Aja, pri trejsanju sem opazil, da se včasih zgodi, da readystate vrne 1 namesto 4. Zakaj?
