Downloadable Web 2.0 and AJAX Widgets
It seems as though every other day a new web 2.0 or AJAX widget comes to the attention of del.icio.us or Google. Many user interface elements lend themselves to being "ajaxified". Calendars, image galleries, contact forms and auto-complete search functions are currently very popular. The problem is how to find working and downloadable examples. This post is an attempt to provide a list of the current best of the best web 2.0 and AJAX widgets that can be downloaded and integrated into your website.
I've been looking at AJAX widgets for about six months now through my own site
mHub so these are ones 've downloaded and installed so I've made sure they are understandable by the average designer or developer.
Before you use the following widgets, it would be a good idea to read the following articles. These articles will guide you on what to do and what not to do with AJAX. Have fun. : )
Jeffrey Veen posts: Designing for the subtlety of AjaxIncreasing the Strength of AjaxAlex Bosworth posts Ajax MistakesAJAX: Image GalleriesZen PhotoOne of the nicest and most complete image gallery with AJAX functions. Features include uploading, comments, AJAX-powered edit-while-you-browse, and a theme engine.
AJAX Image Gallery Example - Alpha ReleaseBoth of these are extreme alpha developer releases. These two examples are really mash-ups of existing code to show what is possible.
AJAX CalendarsMonket CalendarAn Ajax enabled online calendar. Drag and drop events to change dates, drag the start/end of an event to create multi-day events, create and edit events without refreshing the page, all with an iCal style interface.The current release works in all major browsers (Firefox, Opera, Safari, and Internet Explorer). IE support still has a few bugs, namely the previous/next month links not working, and the need to click on a multi-day event before you can resize it.
AJAX Contact FormsDustin's Ajax Contact FormAt this point this is probably the most used AJAX contact form on the web. I first found it right after he first made one for himself and announced it but had no download or documentation. Now he has a nice page devoted to his easy to use AJAX contact form with a download and documentation.
AJAX and PHP Form ProcessingThis is a nice tutorial, with example file that shows you how to make a php contact form with some easy to understand AJAX effects from Scriptaculous.
The Zapatec AJAX Forms Very nicely executed forms with a stripped down free download. These forms, "perform validation, provide feedback, and display error messages that enrich the user's experience while reducing the communications with the server behind the scenes." The paid versions have some amazing functionality.
Ajax Keyword SuggestAjax Keyword Suggest DemoWant to add Keyword Suggest functionality into your site without installing new software? No Problem. Simply Login to ajaxed.com and create and customize your own Keyword Suggest List. All you have to do is copy and paste a small piece of code into your html page and you'll have the feature running instantly.
Ajax Suggest box for HTML FormsTutorial explaining how to use Ajax (Asynchronous Javascript and XML) to create a drop-down 'suggest' box for form fields which updates as you type by querying the server in the background. Similar to the 'Google Suggest' application. Full tutorial, code snippets and further reources.
AJAX Login SystemsCreating a secure login system using XMLHttpRequestThis is an example of a login system that does not require page refreshes, but is still very secure.
AJAX SlideshowsAJAX SlideshowIt resizes, it transitions, it fades in and out and it's not flash! The new AJAX slideshow on the homepage of my site comes to you courtesy of Scott Upton at Uptonic.
AJAX SurveysAsynchronous PollingThis example shows how you can use AJAX to do server-side polling without to update page data without a page refresh.
Tabbed AJAX WebsitesMake an AJAX Website in Less than 10 MinutesI've been toying around with AJAX apps and XMLHttpRequest but have wanted to put up a site that loads all of its content asynchronously. If you're like me and you learn best from working with examples you're only 10 minutes away from your first AJAX website.
Ajax Project - Tabbed Page InterfaceThere are quite a few Javascript implementations of tabbed interfaces out there on the web. How much better, though, to be able to change from pagetab to pagetab without a page refresh? Here's an example of a tabbed interface using Ajax to load the new pages.
實戰(zhàn)Acegi：使用Acegi作為基于Spring框架的WEB應(yīng)用的安全框架
最近項目使用Acegi作為安全框架的實現(xiàn),效果不錯,就寫了這篇文章作為總結(jié).
對于任何一個完整的應(yīng)用系統(tǒng)，完善的認(rèn)證和授權(quán)機(jī)制是必不可少的。在基于SpringFramework的WEB應(yīng)用中，
我們可以使用Acegi作為安全架構(gòu)的實現(xiàn)。本文將介紹如何在基于Spring構(gòu)架的Web應(yīng)用中使用Acegi，并且詳細(xì)介
紹如何配置和擴(kuò)展Acegi框架以適應(yīng)實際需要。
文章和代碼下載:

注意：許多朋友在部署上遇到一些麻煩，所以我將可以部署的完整的war文件傳上來，注意：java代碼在acegi-sample.war\WEB-INF 目錄下，例子需要Mysql，建庫腳本在acegi-sample.war\db目錄下。
acegi-sample.part1.rar
acegi-sample.part2.rar
acegi-sample.part3.rar
acegi-sample.part4.rar
附注：
有些朋友詢問我如何部署文中的例子，在此再次說明一下（文章中已經(jīng)有提到）：
Mysql的建表腳本在db目錄下
為了減小體積，已經(jīng)將WEB-INF\lib下的依賴包刪除，請自行下載以下包，并拷貝至WEB-INF\lib下：
spring-1.2.4.jar
acegi-security-0.8.3.jar
aopalliance-1.0.jar
c3p0-0.9.0.jar
commons-logging-1.0.4.jar
