Is it possible to customize / change the description content of a fb-share button?

问题

This is my code, it's from Facebook, it's quite simple:

<div class="fb-share-button" data-href="http://www.mysite.com/" data-type="button_count"></div>

But when I click on the share button, I found that I can't control the description content of the website. Some other sites did but I don't know how they did it.

Is it possible to change it?

Thanks

Facebook Has complete instruction and the available properties you can add on The Open Graph protocol site

The basic meta tags are

<meta property="og:title" content="{My Title}" />
<meta property="og:type" content="{Site Type}" />
<meta property="og:url" content="http://example.com" />
<meta property="og:image" content="http://example.com/images/og_image.jpg" />

And there's more options if you want to add them

no you can't. You control the content with og metatags. If you want to provide a different description, you need to post via app, with the share dialogue: https://www.facebook.com/dialogue/feed?app_id=APP_ID&link=YOUR_LINK&description=YOUR DESCRIPTION&picture=A_PICTURE_URL&name=SITE TITLE&caption=BEST THINGS EVER etc etc
