To define the URL to share you do it in one of three ways. First, you set it in the toolbox div:
<div class="addthis_toolbox addthis_default_style " addthis:url="THE URL">
or you can set it using the addthis_share variable:
<script type="text/javascript">
var addthis_share = {
url: "THE URL"
}
</script>
or you can set it using the addthis_share variable:
<script type="text/javascript">
var addthis_share = {
url: "THE URL"
}
</script>
If you're using Facebook Like you set the fb:like:href
<a class="addthis_button_facebook_like" fb:like:href="THE URL"></a>
Finally, for Twitter, you set it using tw:url
<a class="addthis_button_tweet" tw:url="THE URL"></a>
Our CMS plugins (Wordpress and Joomla) will do this automatically.
