Administrators vB_AJAX_Handler (fresh look)

[محروم.كوم]

Recently rewrote my js script and noticed that the class vB_AJAX_Handler not changed with version 3.7. I offer my version.
Code:
function vB_AJAX_Handler() {
this.handler = null;
this.conn = null;
};
vB_AJAX_Handler.prototype = {
init: function(){
return AJAX_Compatible;
},
is_compatible: function(){
return AJAX_Compatible;
},
onreadystatechange: function(callback, scope){
this.callback = callback;
this.scope = scope;
},
fetch_data: function(xml){
var el = (typeof(xml) == "string") ? [xml] : xml, data = {};
for(var i = 0; i < el.length; i++)
{
data[el[i]] = this.handler.responseXML.getElementsByTagName(el[i])[0].firstChild.nodeValue;

}
return (i < 2) ? data[xml] : data;
},
send: function(uri, postData) {
this.conn = YAHOO.util.Connect.asyncRequest("POST", uri, {
success: this.callback,
failure: vBulletin_AJAX_Error_Handler,
timeout: vB_Default_Timeout,
scope: this.scope
}, postData + "&securitytoken=" + SECURITYTOKEN + "&s=" + fetch_sessionhash());
this.handler = this.conn.conn;
}
};
Updated methods: fetch_data and send.
Usage:

First variant
Code:
var xml = new vB_AJAX_Handler();
xml.onreadystatechange(function(o){
if (o.responseXML)
{
this.cont = document.createElement("div");
this.cont.id = "lsa_cont";
this.cont.style.position = "absolute";
this.cont.style.display = "none";
this.cont.innerHTML = xml.fetch_data("lsagetwin");
document.body.appendChild(this.cont);
this.textobj.value = '';
this.resobj = D.get("lsa_results");
this.init();
new Y.DD(this.cont.id).setHandleElId("lsadd");
this.winop();
init_collapsers();
}
}, this /* able to use inside your object */);
xml.send("ajaxlivesearch.php?do=lsawin","&do=lsawi n");
Second variant Code:
var xml = new vB_AJAX_Handler();
xml.scope = this;
xml.callback = function(o){
if (o.responseXML)
{
this.cont = document.createElement("div");
this.cont.id = "lsa_cont";
this.cont.style.position = "absolute";
this.cont.style.display = "none";
this.cont.innerHTML = xml.fetch_data("lsagetwin");
document.body.appendChild(this.cont);
this.textobj.value = '';
this.resobj = D.get("lsa_results");
this.init();
new Y.DD(this.cont.id).setHandleElId("lsadd");
this.winop();
init_collapsers();
}
};
xml.send("ajaxlivesearch.php?do=lsawin","&do=lsawi n");
Example with quick_edit Code:
var xml = new vB_AJAX_Handler();
xml.onreadystatechange(function(ajax)
{
if (ajax.responseXML)
{
if (YAHOO.util.Dom.get("progress_" + vB_QuickEditor.postid))
{
YAHOO.util.Dom.get("editimg_" + this.postid).setAttribute("src", vB_QuickEditor.editimgsrc);
}

document.body.style.cursor = 'auto';

// collect items from response object
var data = xml.fetch_data(["contenttypeid", "userid", "attachlimit", "max_file_size", "auth_type", "posthash", "poststarttime", "values", "phrases"]);

if (fetch_tag_count(ajax.responseXML, 'disabled'))
{
// this will fire if quick edit has been disabled after the showthread page is loaded
window.location = 'editpost.php?' + SESSIONURL + 'do=editpost&postid=' + this.postid;
}
else if (fetch_tag_count(ajax.responseXML, 'error'))
{
// do nothing
}
else
{
if (ajax.responseXML.getElementsByTagName("contenttyp eid").length > 0)
{
vBulletin.attachinfo = {
contenttypeid : data.contenttypeid,
userid : data.userid,
attachlimit : data.attachlimit,
max_file_size : data.max_file_size,
auth_type : data.auth_type,
posthash : data.posthash,
poststarttime : data.poststarttime
};

var values = data.values;
if (values.length > 0 && values[0].childNodes.length)
{
vBulletin.attachinfo.values = {};
for (var i = 0; i < values[0].childNodes.length; i++)
{
if (values[0].childNodes[i].nodeName != "#text" && typeof(values[0].childNodes[i].childNodes[0]) != "undefined")
{
vBulletin.attachinfo.values[values[0].childNodes[i].nodeName] = values[0].childNodes[i].childNodes[0].nodeValue;
}
}
}

var phrases = data.phrases;
if (phrases.length > 0 && phrases[0].childNodes.length)
{
for (var i = 0; i < phrases[0].childNodes.length; i++)
{
if (phrases[0].childNodes[i].nodeName != "#text" && typeof(phrases[0].childNodes[i].childNodes[0]) != "undefined")
{
vbphrase[phrases[0].childNodes[i].nodeName] = phrases[0].childNodes[i].childNodes[0].nodeValue;
}
}
}
}

var editor = fetch_tags(ajax.responseXML, 'editor')[0];
if (typeof editor == 'undefined')
{

if (fetch_object(this.editorid + '_edit_reason'))
{
this.unchanged_reason = PHP.unhtmlspecialchars(reason);
fetch_object(this.editorid + '_edit_reason').value = this.unchanged_reason;
fetch_object(this.editorid + '_edit_reason').onkeypress = vB_AJAX_QuickEditor_Events.prototype.reason_key_tr ap;
}

// initialize the editor
vB_Editor[this.editorid] = new vB_Text_Editor(
this.editorid,
editor.getAttribute('mode'),
editor.getAttribute('parsetype'),
editor.getAttribute('parsesmilies'),
undefined,
undefined,
editor.getAttribute('content')
);

if (fetch_object(this.editorid + '_editor') && fetch_object(this.editorid + '_editor').scrollIntoView)
{
fetch_object(this.editorid + '_editor').scrollIntoView(true);
}

vB_Editor[this.editorid].set_editor_width('100%', true);
vB_Editor[this.editorid].check_focus();
