Passing custom text to new Facebook Sharer button

Question

I need to pass some AngularJS variables from my application to the new Facebook sharer button, I'm using:

<div id="fb-root"></div>
<script>(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/es_LA/all.js#xfbml=1&appId=1438439249728371";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>

And this:

 <div class="fb-share-button" data-href="http://mySite" data-type="button">     </div>

Where can I place my custom text to share in the dialog?

Thank you!

Answer 1

Sharer wont allow that. It'll fetch the og tags from the link and fill the contents in the dialog.

If you want to add cutomized description/picture/caption you should instead use Feed Dialog .

You can use the direct URL to invoke feed dialog:

https://www.facebook.com/dialog/feed?
 app_id=1438439249728371
 &display=popup
 &caption={caption}
 &link={link-to-share}
 &description={description}
 &redirect_uri={redirect-url-to-your-site}

You can check all available parameters here

If you use the Facebook SDK for JavaScript you have to use the parameter quote

  FB.ui({
    method: 'share',
    display: 'popup',
    href: window.location.href,
    quote: "Your Custom Text"
  }, function(response){});
