Introduction - A set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, DHTML and AJAX. - The library was developed by Yahoo!’s client-side platform engineering team.

Introduction The library is divided into two logical sections: The library is divided into two logical sections: –Utilities  Reusable infrastructure libraries that handle things like events, AJAX calls, animation and drag & drop –Controls  Reusable interactive components, like sliders, menus, and calendars, that are built using the utility libraries

Example: animation/motion_plus.html Example: animation/motion_plus.html animation/motion_plus.html animation/motion_plus.html

UTILITIES: Drag & drop Create draggable objects that can be picked up and dropped elsewhere on the page. Create draggable objects that can be picked up and dropped elsewhere on the page. The utility keeps things working smoothly in all supported browsers. The utility keeps things working smoothly in all supported browsers. Example: dragdrop/list.html?mode=dist Example: dragdrop/list.html?mode=dist dragdrop/list.html?mode=dist dragdrop/list.html?mode=dist

UTILITIES: Dom Collection The Dom Collection comprises a family of convenience methods that simplify common DOM-scripting tasks, including element positioning and CSS style management, while normalizing for cross- browser inconsistencies.

CONTROL: Autocomplete The AutoComplete Control allows you to streamline user interactions involving text-entry. The AutoComplete Control allows you to streamline user interactions involving text-entry. The control provides suggestion lists and type- ahead functionality based on a variety of data- source formats and supports server-side data- sources via XMLHttpRequest.

Example: omplete/ysearch_xml.html Example: omplete/ysearch_xml.html omplete/ysearch_xml.html omplete/ysearch_xml.html

CONTROL: Slider The Slider component is a UI control that enables the user to adjust values in a finite range along one or two axes. The Slider component is a UI control that enables the user to adjust values in a finite range along one or two axes. Typically, the Slider control is used in a web application as a rich, visual replacement for an input box that takes a number as input. Typically, the Slider control is used in a web application as a rich, visual replacement for an input box that takes a number as input. Example: rgb.html?mode=dist Example: rgb.html?mode=dist rgb.html?mode=dist rgb.html?mode=dist

CONTROL: Button The Button Control provides checkbox, radio button, submit and menu-button UI elements that are more impact visually and more powerful programmatically than the browser's built-in form widgets. The Button Control provides checkbox, radio button, submit and menu-button UI elements that are more impact visually and more powerful programmatically than the browser's built-in form widgets.

CONTROL: Menu Application-style fly-out menus require just a few lines of code with the Menu Control. Menus can be generated entirely in JavaScript or can be layered on top of semantic unordered lists. Application-style fly-out menus require just a few lines of code with the Menu Control. Menus can be generated entirely in JavaScript or can be layered on top of semantic unordered lists. The Menu family of components features a collection of controls that make it easy to add menus to your website or web application.

Example: /programsmenu.html Example: /programsmenu.html /programsmenu.html /programsmenu.html

CONTROL: TreeView The TreeView control produces a content tree whose nodes can be expanded and contracted by user interaction (and by script, where necessary). The TreeView control produces a content tree whose nodes can be expanded and contracted by user interaction (and by script, where necessary). The nodes can contain links or custom properties and can be loaded dynamically. The nodes can contain links or custom properties and can be loaded dynamically. The display of the node elements can be customized with CSS to create a folder view, to- do task list, or other visual treatment. The display of the node elements can be customized with CSS to create a folder view, to- do task list, or other visual treatment.
