在Facebook上分享链接，如何重新初始化FB OBJ

我正在做一个项目，该项目需要在弹出窗口中显示Facebook，Twitter，google+图标以共享链接的功能。

Twitter和Google+对我来说很好用。但是在 facebook 的情况下，当我第一次加载弹出窗口时会显示共享图标，但在我再次加载弹出窗口后它不会显示，直到刷新主页。

我认为这是因为，fb obj 在第一次加载弹出窗口时已经初始化，以防止在弹出窗口重新加载时重新初始化。

任何人都可以建议，我该如何解决这个问题。

我使用了以下代码：

谷歌+

<a href="https://plus.google.com/share?url=<?php echo 'dynamically_created_link_with_querystring';?>" onclick="javascript:window.open(this.href,'', 'menubar=no,toolbar=no,resizable=yes,scrollbars=yes,height=600,width=600');return false;">
<img src="https://www.gstatic.com/images/icons/gplus-16.png" alt="Share on Google+"/></a>

<script>
window.twttr = (function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0],
    t = window.twttr || {};
  if (d.getElementById(id)) return;
  js = d.createElement(s);
  js.id = id;
  js.src = "https://platform.twitter.com/widgets.js";
  fjs.parentNode.insertBefore(js, fjs);
  t._e = [];
  t.ready = function(f) {
    t._e.push(f);
  };
  return t;
}(document, "script", "twitter-wjs"));
</script>
<a href="http://www.twitter.com/intent/tweet?url=<?php echo 'dynamically_created_link_with_querystring';?>" >
