var t = 1;
dhx.ajax.get("server.php", function(){
    t = 2;
});
console.log(t); // still 1

header("Content-Type: text/xml");
<!-- assuming that the response is the following -->
<items>
    <item name="first" value="a"/>
    <item name="second" value="b"/>
</items>
dhx.ajax.get("server.php", function(r){
    var items = [];
    var xml = r.xmlDoc.responseXML;
    var nodes = xml.getElementsByTagName("items");
    for (var q=0; q<nodes.lengt; q++) {
        items.push({
            name:   nodes[q].getAttribute("name"),
            value:  nodes[q].getAttribute("value")
        });
    }
});
  • getting json from response
// assuming that the response is the following
{status: "ok", data: "value", data2: "value2"}
dhx.ajax.get("server.php", function(r){
    var t = window.dhx.s2j(r.xmlDoc.responseText); // convert response to json object
    if (t != null && t.status == "ok") {
        // response is ok
    }
});
