Useful JavaScript Classes and Functions

  • Crossbrowser image reflections enabler JavaScript class.
  • JavaScript Mapper Class for RESTFul Methods – Recently I had to work with a bunch of RESTFul API methods, so instead of defining manually separate calls/methods for each API request, I decided to do it viceversa – to force JavaScript to create these methods automatically for me out of the RESTFul API by providing the URLS and other required data.
  • XML to JSON JavaScript Objectifier Class – Simple XML to JSON objectifier. It can be used with custom or public XML, REST APIs such as Last.FM, RSS and ATOM feeds, sitemaps, etc by converting the XML server responses to native JSON objects in the browser which are then instantly accessible by its simple to use JavaScript methods.
  • URI to JSON Serializer Class – Tiny JavaScript class, using the HTMLAnchorElement interface to convert URI string into a JSON object.  The object returned by the function contains hash, host, hostname, parameters key-value map, pathname, port and protocol. Works with all major browsers (Firefox, Chrome, Safari, Opera, IE6-10).
  • IMDB Fetcher – Experimental IMDB JavaScript and PHP API – Makes possible the execution of cross-domain AJAX queries to IMDB and returns a JSON data object for the requested movie. What is currently supported – movie title, poster, release date, description, actor(s), director(s), IMDB and MPAA rating, running time, etc.
  • Quick and Dirty Localization With JavaScript – A quick and dirty JavaScript localization routine that provides basic localization (no support for plurals, etc), operates on the DOM of the page and uses data-lang attribute for language keys storage. Lokalizr works with all major browsers, beginning with IE8.
  • JavaScript Instance Name Finder – Small JavaScript function that checks for instances of an object within a defined scope and returns an array of instances’ variable names that can be used for different purposes.
  • HTML5 Placeholder Enabler – The solution presented in this post checks for the availability of the placeholder attribute in textboxes, and if it is not available applies its content as value to the elements that contain it.
  • HTML 5 Details Element Enabler – According to WhatWG, the “<details /> element represents a disclosure widget from which the user can obtain additional information or controls“. In brief, you can use it to create panelbar elements without JavaScript, as the expand / collapse functionality is native to it. Currently (October, 2011), the only browser which supports <details /> is Google Chrome, so if you are eager to start using this element on your pages, you can do so with the help of a few lines of JavaScript to make sure it works on all browsers.
