Добрый день. Не так давно на своем сайте wordpress в исходном коде на всех страницах сайта увидел скрипт, которого ранее вроде не было, подскажите, что это?
Вредоносно, или нет?Спасибо.
<script type="text/javascript">
'use strict';
(function (w) {
var darx = {};
darx.addEvent = function (elem, event, fn) {
if (elem.addEventListener) {
elem.addEventListener(event, fn, false);
} else {
elem.attachEvent('on' + event, function () {
return (fn.call(elem, window.event));
});
}
};
darx.fireEvent = function (elem, event) {
var evt = elem.createEvent('Event');
evt.initEvent(event, true, true);
elem.dispatchEvent(evt);
};
darx.get = function (url, data, callback) {
sendRequest('GET', url, data, callback);
};
darx.post = function (url, data, callback) {
sendRequest('POST', url, data, callback);
};
darx.getJSON = function (url, data, callback) {
var callbackName = 'darx_jsonp_' + Math.round(1000000000 * Math.random());
window[callbackName] = function(data) {
delete window[callbackName];
document.body.removeChild(script);
callback(data);
};
var script = document.createElement('script');
script.type = "text/javascript";
script.async = true;
data.callback = callbackName;
script.src = url + '?' + http_build_query(data);
document.body.appendChild(script);
};
var http_build_query = function (data) {
var params = [];
var type;
for (var key in data){
if (data.hasOwnProperty(key)) {
type = Object.prototype.toString.call(data[key]);
if (type === '[object Array]' || type === '[object Object]') {
for (var i in data[key]) {
if (data[key].hasOwnProperty(i)) {
params.push(encodeURIComponent(key) + '[]=' + encodeURIComponent(data[key][i]));
}
}
} else {
params.push(encodeURIComponent(key) + '=' + encodeURIComponent(data[key]));
}
}
}
return params.join('&');
};
var sendRequest = function (method, url, data, callback) {
var xhr = false;
var XMLHttpFactories = [
function () {return new XMLHttpRequest()},
function () {return new ActiveXObject("Msxml2.XMLHTTP")},
function () {return new ActiveXObject("Msxml3.XMLHTTP")},
function () {return new ActiveXObject("Microsoft.XMLHTTP")}
];
for (var i=0; i<XMLHttpFactories.length; ++i) {
try { xhr = XMLHttpFactories[i]() } catch (e) { continue; }
break;
}
if (!xhr) return;
if (method === 'GET') {
data.r = Math.random();
url += '?' + http_build_query(data);
}
xhr.open(method, url, true);
xhr.setRequestHeader("X-Requested-With", "XMLHttpRequest");
xhr.timeout = 5000;
if (callback) {
xhr.loaded = xhr.onreadystatechange = function () {
if (xhr.readyState !== 4) return;
callback(xhr.responseText, xhr);
}
}
if (method !== 'GET') {
xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhr.send(http_build_query(data));
} else {
xhr.send(null);
}
};
w.darx = darx;
}(window));
</script>
