<script>
!function (d, id, did, st) {
  var js = d.createElement("script");
  js.src = "//connect.ok.ru/connect.js";
  js.onload = js.onreadystatechange = function () {
  if (!this.readyState || this.readyState == "loaded" || this.readyState == "complete") {
    if (!this.executed) {
      this.executed = true;
      setTimeout(function () {
        OK.CONNECT.insertShareWidget(id,did,st);
      }, 0);
    }
