How can I make the Facebook Like button's width automatically resize?

阅读更多关于 How can I make the Facebook Like button's width automatically resize?

问题 I'm implementing the Facebook Like Button, but I'm running into some trouble with the width. I'm using the JavaScript SDK implementation, not the direct iframe. According to the documentation, the default width is 450 . That's fine, and I understand that the width can be changed by way of the width attribute on the <fb:like> tag. However, my problem is that I really cannot specify a fixed width. Due to the nature of the button, the width is not constant in all states. For example, if no one

Playing back an embedded mp4 video in a Facebook like or share using Flash

阅读更多关于 Playing back an embedded mp4 video in a Facebook like or share using Flash

问题 I have an H.264-encoded mp4 file that I'm trying to get embedded into a Facebook post when the page that's serving it is Liked or Shared. My understanding is that I simply need to have the right Open Graph <meta> tags in place on the URL that's being liked/shared. However, I've tried several different sets of <meta> tags and the video is still not embedding when I paste the URL into my Status Update and Post it. It does embed the image from the og:image property, but clicking on the image

How do I test the Facebook “Like” button on localhost?

阅读更多关于 How do I test the Facebook “Like” button on localhost?

It is possible to test " Like " button on localhost? M.G.Palmer Dave's answer is correct, however, I just discovered a workaround: You can make your local machine accessible by using http://localtunnel.me . You'll need to (temporarily) change some URLs used in your app code / html so links point to the temporary domain, but at least facebook can reach your machine. Not really; facebook has to crawl your site to pull in the title, description, and thumbnail. It can't get to your site if it's on localhost. It is possible to perform limited testing on the facebook like button on localhost. It

阅读更多关于 How to programmatically “press” a 'Like' button through a Facebook Application?

问题 I'm developing this Facebook Application and I was wondering if it's possible (and how) to programmatically, through the Facebook PHP Graph API, press some 'Like' button on some page? Of course, this is optional on my application... I'm still not ready to really explain what application I'm doing, but it would be interesting to code such a feature. Is it possible somehow? 回答1: You cannot do this. Facebok wont let you do a POST to /POST_ID/likes, you can only do a get request to retrieve their

Possible Duplicate: Retrieve Facebook Fan Names I wanna get a list of facebook users who like a page or interest. FQL like ' SELECT user_id FROM like WHERE object_id=113970468613229 ' does not work. Is there a way to do this? I am Partner Engineer at Facebook so I thought I'd chime in here. The Facebook APIs will not give you the user ID of users who have liked a page or interest, this is to guard the privacy of those users. There is no way to get a list of people that like your page via their API, which is why this question never got answered. You can get charts and aggregate information

问题 With Facebook we have the Open Graph tags that allow webmasters to specify how the story is displayed on Facebook. Is there something similar for the Google +1 button, that allows webmasters to specify the thumbnail image, description and title? Google+ seems to be ignoring the og-meta tags . 回答1: From Google+ help docs, we now have an official answer . Google uses schema.org microdata to generate rich snippets in search (and in Google+).
