For Facebook and for Google i found this solution..
<script type="text/javascript">
$(document).ajaxComplete(function(){
try{
FB.XFBML.parse();
gapi.plusone.go();
}catch(ex){}
});
</script>
but not for tumblr. Does anybody know if there is any solution? Tubmlr-post-button is implemented like this:
<a class="tumblr-share-button" data-href="http://www.xy.ch/news_entries/<? php echo "{$row['title']}.html" ?>" data-content="http://www.xy.ch/news_entries/<?php echo "{$row['title']}.html" ?>" data-color="blue" data-notes="right" href="https://embed.tumblr.com/share"></a>
Thanks M
