**lulluana** · 2010-01-18, 13:00

I just made simple widget
It load a local xml using AJAX XMLHttpRequest
working on FF server with WRT

working on SDK s60 5th as well
anyway I don't know how I can see Korean character on SDK..
As you See , All Korean character are broken
Doesn't it support Korean?

and...Doesn't work on my phone 5800
I have no idea what's going on this
I get a 0 status just only on my phone!
Isn't there any expert? need help~

Code:

var xmlhttp;
function loadXMLDoc(){
    xmlhttp = null;
    if (window.XMLHttpRequest) {// code for IE7, Firefox, Mozilla, etc.
        xmlhttp = new XMLHttpRequest();
    }
    else 
        if (window.ActiveXObject) {// code for IE5, IE6
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        }
    if (xmlhttp != null) {
        url = "main.xml";
        xmlhttp.onreadystatechange = onResponse;
        xmlhttp.open("GET", url, true);
        xmlhttp.send(null);
    }
    else {
        alert("Your browser does not support XMLHTTP.");
    }
}

function onResponse(){
	//alert("xmlhttp.readyState = " + xmlhttp.readyState);
	//alert("xmlhttp.status = " + xmlhttp.status);
    if (xmlhttp.readyState != 4) 
        return;
    if (xmlhttp.status != 200) {
        alert("Problem retrieving XML data");
        return;
    }
    var oObj = xmlhttp.responseXML;
    
    var Wek = oObj.getElementsByTagName('CATALOG');
    We1 = Wek[0].childNodes;
    
    for (y = 0; y < We1.length; y++) {
        Wy = We1[y].childNodes;
        for (i = 0; i < Wy.length; i++) {
            Wn = Wy[i].nodeName;
            Wk = Wy[i].childNodes.length;
            for (z = 0; z < Wk; z++) {
                Wa = Wy[i].childNodes[z].firstChild.nodeValue + "<br>";
                document.getElementById(Wn).innerHTML += Wa;
            }
        }
    }
}

Hi,

a suggestion about a possible workaround: if you need to read and use local widget's data, you could give a look at JSON. It allows you to specify data in a format that is natively interpreted by JavaScript, so avoiding you the need to load and parse XML (or similar) data files.
