Validating Your Data (06/01/2007)
(...) • The Web client is considered insecure, so the server could receive invalid data if clientside validation is the only validation. Client-side validation saves processing power on the server side by doing the validation and using the resources of the client. The downside is that in an HTML application, the client is considered insecure, and hackers can always bypass the security efforts of aWeb developer. (...)

Creating Dynamic Layouts (06/01/2007)

Manipulating Dynamic Content Blocks (06/01/2007)

Implementing Dialog Boxes (06/01/2007)

Dealing with Formatted Data and Forms (06/01/2007)
(...) The advantage of doing a one-to-one mapping is that it simplifies the work for you. It’s easier for you to write a database statement such as “Search for this city” rather than “Search for this thing, which could be a city, address, or country.” Yet, the seemingly vague input is the better approach from the perspective of the user.

Implementing an SOA Architecture (06/01/2007)
(...) HTML is a user interface technology that is not universally understood across all devices. An Atom end device could probably guesstimate the format structure, but you probably know the sweat and pain associated with writing HTML code that can display on all devices. With aWeb service based on the Atom format, you have a clear understanding of what the data is and represents. (...)

Implementing the Synchronous Class in Ajax (06/01/2007)
(...) You still provide a settings code block, and you still call the get function. The reason this approach works is due to the way that Asynchronous and Synchronous are wired together, as illustrated by the following code: function Asynchronous(userSettings) { this.xmlhttp = new FactoryXMLHttpRequest(); this.

Handling Errors in AJAX (06/01/2007)

For developers, it is easy to figure out the source of the error, but users are often bewildered. The generalized approach is effective because of the way the error is routed. (...)

Identifying the Resource and Representation using Ajax (06/01/2007)
(...) Separating the resource from the representation means that a single URL will have separate representations. The representation that is sent depends on the value of the HTTP Accept-* header, but doesn’t need to be the only one. Let’s focus on the Accept HTTP header and consider the following HTTP conversation that returns some content. (...)

Ajax Closed Access Web Services (06/01/2007)
(...) That lack of documentation is the decision maker of whether you use REST to store data, or whether you use background processes. The database vendors aren’t going to allow you to add data to their database using C file operations, because you would corrupt the database. Whenever you execute a SQL insert statement, a whole host of things happen (such as indexing and optimization) that wouldn’t occur if you accessed the database directly. (...)

Efficiency is one of the requirements of this solution, but remember that efficiency is relative, and the solution will be as efficient as possible for the context. As you know, in any search engine, you enter a term or phrase in a text box, click the Search button, and the relevant HTML pages are returned for the term or phrase you typed in. (...)
