dope
dope is cross-browser JavaScript module for working with HTML attributes. It includes an HTML5 dataset API abstraction that adheres to the specification. It works standalone or can integrate into jQuery-compatible hosts. It runs screamin-fast and gzips < 2k. Got data? =)
API (2.2)
In standalone usage, methods are available on the dope namespace. The docs below use $ to denote dope or a host library like jQuery or ender.
dope.dataset(document.body, 'foo', 'bar'); // standalone
$.dataset(document.body, 'foo', 'bar'); // integratedChain methods
$.fn.attr()
$(elem).attr(key) // get attribute on elem (or 1st elem in collection)
$(elem).attr(key, value) // set attribute on elem (or on collection)
$(elem).attr(object) // set multiple attributes via key/value pairs$.fn.removeAttr()
$(elem).removeAttr(keys) // remove 1 or more SSV attributes from elem or collection$.fn.dataset()
$(elem).dataset() // get all data-* attributes on elem (or 1st elem in collection)
$(elem).dataset(key) // get data-* attribute on elem (or 1st elem in collection)
$(elem).dataset(key, value) // set data-* attribute on elem (or on collection)
$(elem).dataset(object) // set multiple data-* attributes via key/value pairs
$(elem).dataset([key]) // get [exact] data-* attribute (primitives render to correct type)$(document.body).dataset('movieName', Pulp Fiction) // set <body data-movie-name="Pulp Fiction">
$(document.body).dataset('movieName') // returns "Pulp Fiction"
$('div').dataset('stars', 5) // set <div data-stars="5"> on all matched divs
$('div').dataset('stars') // returns "5"
$('div').dataset(['stars']) // returns 5$.fn.deletes()
$(elem).deletes(keys) // remove 1 or more SSV data-* attributes from elem or collection$(document.body).deletes('movieName') // remove [data-movie-name] from the <body> elementStatic methods

$.trim(str) // Trim surrounding whitespace.$.parse()
$.parse(str) // Convert stringified primitives to correct value. Non-strings are unchanged.
$.parseJSON(str) // Parse JSON. Safely wraps `JSON.parse` so that it won't throw an error.$.parse and $.parseJSON trim "string" inputs before parsing them.
$.parse('yo') // 'yo'
