YUI 有哪些優點？

最符合使用者需求你每天都在用的網站是？

所有的 Library 必需符合使用者經驗的設計

Problem Summary

The user needs to enter an item into a text box which could ambiguous or hard to

remember and therefore has the potential to be mis-typed.

EXAMPLE:

Auto completion of contacts in Yahoo! Mail Beta

Use When

The suggestions can be pulled from a manageable set of data.

The input item can be entered in multiple ways.

The input item can be matched with a specific data item in the system.

Speed and accuracy of entry is an important goal.

The total number of items would be too large or inconvenient for displaying in a

standard drop down box.

Solution

Layout

Use a standard text box for input.

Label the text box to match the user's expection of what field will be searched against.

Interaction

As the user types, display a list of suggested items that most closely match what the

user has typed. Continue to narrow or broaden the list of suggested items based on the

user's input.

Display the suggested items list in a drop down box directly underneath the text box.

The suggested items list may be based on the complete set of data or more narrowly

based on other criteria such as each item's frequency of use.

When available, show multiple fields of information for each suggested item. In the

Yahoo! Mail example above, two fields are presented: the contact's full name and the

contact's email address.

Highlight the closest matching item within the suggested items list.

Show the matched item as first in the list.

Highlight the background of the matched item.

When multiple fields are shown for each suggested item the match may occur

with the initial characters of any of the fields presented.

For each suggested item in the suggest items list show the characters that exactly

match the user's input. When multiple fields are shown in a suggested item the

matching characters may appear in any of the fields presented. In the example below,

the characters 'Yu' have been typed by the user. The match is on three items. Notice

that the first item matched on the contact's email address '<yuiblogger.com>' whereas

the second and third items are matched on the contact's name (e.g., 'Yusef Jones'.)

Allow the user to delete a character of input and display the previous suggested items

list.

Allow the user to complete the input field by pressing the Tab key or Enter; key. The

current matched item in the suggested items list will be accepted as the value for the

input field.

Allow the user to optionally highlight an item of their choice from the suggested item list

with the mouse or with the up and down arrow keys.

Allow the user to cancel the suggested items list by pressing the Esc key. The drop

down list will close. Subsequently pressing the Tab key or Enter key will accept the

value from the input field. However, typing more characters after hitting the Esc key will

restart the auto completion behavior displaying the suggested items list.

If multiple input items are allowed in a single input field, allow the user to use the

Comma key to separate each input item.

Pressing the comma key will complete an individual item match.

The auto complete behavior restarts when the user begins typing characters for

the next input item.

Rationale

Reducing the number of keystrokes allows for faster user input.

Showing additional formatting information in the suggested items list (like the email

address in the example above) removes ambiguity.

Continual feedback helps the user narrow in on the correct choice.

Accessibility

Label the text box to match the user's expection of what field will be searched against.

Allow the user to highlight a desired match either using a mouse or navigating to it with

the up or down arrow keys.

Allow the user to complete the form by pressing the Tab or Enter keys.

Allow the user to cancel suggestions by pressing the Esc key.

Allow the input field to receive keyboard focus by pressing the Tab key.

Once the edit field is in focus make sure that the focus stays in the edit field during

autocomplete.

Do not send any page refreshes when updating the field (page refreshes will signal

assistive technology to start reading the page again.)

The insertion cursor should move as the left/right arrow keys are pressed in the text

field.

Getting Started

1. Check out the examples of YUI in action. We recommend starting withthe Event Utility and Dom Collection examples; Event and Dom are part ofthe YUI Core (along with the YAHOO Global Object) and provide animportant foundation for JavaScript developers using YUI. Once you'vereviewed those foundational pieces, go on to explore utilities like Drag andDrop and Animation or UI controls like Button, Calendar and TabView. Ifyou're interested in YUI's CSS components, read through the examples forReset, Base, Fonts, and Grids in that order.

2. Remember that there are full user's guides for each component here onthe website. If you have any questions about a component as you play withthe examples, check out the component's user's guide (by following any ofthe links along the left side of the page) or the searchable APIdocumentation.

3. You have cheat sheets for each component available on landing pagesand downloadable as a full set. These documents support the online user'sguides by providing concise print documentation for YUI components.

4. Start building. You can include YUI scripts and CSS from the YUIdownload (in the /build directory) or directly from Yahoo! servers. The

YUI Loader Utility is a client-side loading package that can dynamically pullin YUI scripts as needed, whether from your servers or from ours.

5. Become a member of the YUI community. YUI developers andimplementers share thoughts and solutions and provide a helping hand inour forums. YUI developers also contribute to the YUIBlog, where you'll findin-depth articles, videos and other great content about YUI and the world offrontend engineering.

Licensing

All of the YUI Library components are provided free of charge under a liberalBSD license.

Articles

Graded Browser Support: This article details the browser-supportphilosophy we use in developing the YUI Library. Graded BrowserSupport provides a sane path to achieving accessibility and gracefuldegradation while still building richly interactive interfaces in thebrowser.Skinning YUI: YUI components get their look and feel from a visual"skin" that you can modify or replace in your own applications.

Cheat Sheets

Cheat Sheets for the YUI Library provide quick references to the key methods,properties, and syntax patterns of each component. When you find yourselfelbow-deep in a coding problem, sometimes it's quicker to turn to these ratherthan firing up a browser to review documentation and examples — and reviewingthe cheat sheets can help you discover hidden gems you didn't know were there.

These one page references aren't comprehensive, but we think you'll find themvaluable to have on hand. (Cheat Sheets are currently provided for all YUIUtilities, nearly all UI Controls, and for the YUI CSS foundation.)

Support & Community

The YUI Library and related topics are discussed on the on the ydn-javascriptmailing list.

In addition, please visit the YUIBlog for updates and articles about the YUILibrary written by the library's developers.

Filing Bugs & Feature Requests

The YUI Library's public bug tracking and feature request repositories are locatedon the YUI SourceForge project site. Before filing new feature requests or bugreports, please review our reporting guidelines.

Guidelines for YUI feature requests and bug reports.Review current bug list or file a new bug.Review current feature requests or file a new feature request.

The Yahoo! User Interface (YUI) Library is a set of utilities andcontrols, written in JavaScript, for building richly interactive webapplications using techniques such as DOM scripting, DHTML andAJAX. The YUI Library also includes several core CSS resources. Allcomponents in the YUI Library have been released as open sourceunder a BSD license and are free for all uses.
