littledom is a really tiny (experimental) jQuery work-alike for modern browsers. Think of it as a curated jQuery subset, optimized for readability and file size.
littledom is not a drop-in replacement for jQuery, but it does implement many of its most commonly used methods. In many cases, not all method signatures are supported either. This keeps the code lean and pretty simple to read. The following parts of jQuery are intentionally omitted- if you need them you might consider a best-of-breed standalone library instead:
* ajax() and friends * promises * any polyfills (a standards-compliant browser is assumed) * utilities intended for objects and arrays ($.each, $.map, etc) * anything else that falls outside out DOM querying and manipulation
Check out the source code, it's concise and should be easy to read and understand.
$dom.ready(callback) -> equivalent to $(document).ready(callback) $dom.browserSupported -> boolean indicating whether the browser is supported by the library. $dom.create(htmlString) -> create a set of elements from an html string (like $(htmlString))
// Manipulation:html() -> return the innerHTML of the first matched elementhtml(contents) -> sets innerHTML for all matched elements to the given stringfind(selector)remove() -> remove all matched elements from the document (doesn't take any arguments)data(attrName) -> return the value of the given data-* attribute (for the first matched element where it's set)data(attrName, val) -> set data-attrName to the given value for all matched elementsappend(content, ...) -> Append content ($dom instances, DOM nodes, or html strings) to each elementprepend(content, ...) -> Same as append(), but inserts at the front of the selection// Traversal:parent() -> Returns all unique parents of the selected elementsunique() -> Returns a unique set of the selected elementsfirst() -> Returns the first selected element (wrapped)last() -> Returns the last selected element (wrapped)closest(selector) -> Returns the closest ancestor that matches the given selector(NOTE! only supports simple tag name selectors for now)// Classes and attributes:addClass(className)removeClass(className)hasClass(className) -> returns true if any matched element has the given classattr(name) -> return the attribute of the first matched elementattr(name, value) -> for all matched elements, set the attribute with the given name to the given value.attr(hash) -> for each matched element, el[attrName] = attrValue for each key, val pair in the objectremoveAttr(<string>)// Styling:css(name)css(name, value)css(hash)show()hide() -> Set "display: none" on all matched elements.// Events:on(eventName, handler)on(eventName, delegationSelector, handler)off(eventName, handler)off(eventName, delegationSelector, handler)trigger(eventName) -> trigger an event on each matched elementbind(), unbind(), delegate(), undelegate() (legacy)// ES5 Array methodseach()map()some()every()filter() -> NOTE: works like the ES5 array method, not jquery's method// MisctoArray() -> Return the matching DOM nodes in an array
* Add support for: .one() .children() * form serialization: to string, and to Object
