connect

Puts Facebook Connect button. If Facebook Javascript SDK initialization code wasn't added into current page, then calling of this tag will call :init automatically.

Optional attributes:

• type - 'server' or 'client', type of authentication to use. By default it uses server-side authentication (if such authentication type is enabled)

Optional attributes for server button (server-side authentication):

• img - url to image for connect button (for server-side authentication only)
• img-* - a attribute for <img> tag, like img-id or img-style
• startUrl - a local url that will prepare valid redirect to Facebook API, instead of default one provided by the plugin. At most cases you don't need to specify this, do it only if you know what you're doing and default implementation is not enough for your case.

Optional attributes for client button (client-side authentication):

• permission - list of Facebook Permission as a String or List
• text - text to display on button, Login with Facebook by default
• skipInit - force to skip Facebook Javascript SDK initialization. By default this tag calls <facebook:init />, if it's not executed yet.
• lang - locale, for Facebook all.js (like 'en_US', 'ru_RU', etc)
