语法错误意外标识符javascript [关闭]

So, I have this small javascript code.

<script type="text/javascript">
function showModalCS() {
  if (window.location.href == "http://domainname.com/check/") {
      document.writeln('<link rel="stylesheet" href="http://domainname.com/style.min.css" />');
      document.writeln('<div id="popup"><span class="button b-close"><span>X</span></span><img src="http://domainname.com/image.png" alt="" /></div>');
      document.writeln('<script src="http://cdnjs.cloudflare.com/ajax/libs/jquery-easing/1.3/jquery.easing.min.js" /><script src="http://domainname.com/script.min.js" />');
      $("#popup").bPopup();
  } else {
      //
  }
}

showModalCS();

</script>

It works fine when I put it inside an html file and upload it using cpanel file manager.

But, when I use joomla's template manager to add this script to the bottom of the index.php it doesn't work. Instead I get an Unexpected Identifier error in chrome's dev tools...

Any ideas on how to fix this?

change you last script tag to

</script>

Script tag can never be self closing try this instead

  document.writeln('
<script src="http://cdnjs.cloudflare.com/ajax/libs/jquery-easing/1.3/jquery.easing.min.js">
</script><script src="http://domainname.com/script.min.js"></script>');
