This is an interface component for websites and Facebook applications which allows your users to make a selection of one or more of their friends. The friends are returned as an array of Facebook IDs. It is similar to the fb:multi-friend-selector component by Facebook, except it can be used to select friends for anything, not just application requests.

You can view the example at These Days Labs, or you can check out this repository and run it yourself. You'll need to put the files on a web server - Facebook apps won't run off the local file system.

Just edit example.js and set your Facebook appId.

• Copy the div element with the ID TDFriendSelector (and all of its children) from index.html.
• There is some text in the HTML. This is where you can localise the plugin to the desired language.

• Include the tdfriendselector.css stylesheet in your document.
• Ensure tdfriendselector.png is located in the same directory as tdfriendselector.css
• We wrote the stylesheet with Sass and have included the SCSS source.

• Include jQuery in your document. We are considering making this plugin library independent, but currently jQuery is required.
• Include the Facebook JavaScript SDK. (Technically, this step is optional. We have provided a setFriends function if you have loaded the friends on the serverside and want to avoid the JavaScript SDK.)
• Include tdfriendselector.js.
• Optional: We are using an HTML5 placeholder attribute on the search field. If you want the placeholder to work in older browsers, include a placeholder polyfill.
• Note: we haven't minified the script for you but you might like to minify it and concatenate it into a single file with your other plugins.

1 - Make sure your user has authenticated your Facebook app.

2 - Initialise the plugin. Here you can set options like toggling debug messages, your preferred classnames, etc.

TDFriendSelector.init({debug: true});

3 - Create an instance of the plugin. We allow multiple instances per page because sometimes you will need users to select friends for more than one thing. You can pass in options here which will only effect this instance, for example a callback to deal with the friends that are selected.

selector1 = TDFriendSelector.newInstance({
	callbackSubmit: function(selectedFriendIds) {
		console.log("The following friends were selected: " + selectedFriendIds.join(", "));
	}
});

4 - Display the plugin instance when you need it. The plugin will automatically load the Facebook friends of the logged in user (and they will be cached and reused across all instances on the page).

$("#btnSelect1").click(function (e) {
	e.preventDefault();
	selector1.showFriendSelector();
});
