/* * Embedly JQuery * ============== * This library allows you to easily embed objects on any page. * * Requirements: * ------------- * jquery-1.3 or higher * * Usage: * ------ * There are two ways to interact with this lib. One exposes a simple method to call embedly directly * * >>> $.embedly('http://www.youtube.com/watch?v=LfamTmY5REw', {}, function(oembed){ alert(oembed.title);}); * * The oembed is either a json object or null * * You can also reference it this way, which will try and replace every link on the page with an embed * * $('a').embedly(); * * The Options Are as Follows * * {maxWidth : null, * maxHeight: null, * urlRe : null, * method : 'replace', * wrapElement : 'div', * className : 'embed', * addImageStyles : true} //after * * http://api.embed.ly/tools/generator - generate your own regex for only sources you want * */ (function ($) { $.embedly = function (url, options, callback) { options = extendOptions(options); if (url != null && urlValid(url, options)) embed(url, options,
