Summary of advantages and characteristics of Flex

◆ does not require browser compatibility testing

One of the features of AJAX is that it is much more complex than ordinary XHTML and some CSS. Browser compatibility testing has since become a terrible nightmare. Because the Flex application is compiled into a Flash SWF file, no matter what operating system and browser you use, it is also downloaded as pixels.

◆ E4X

Anyone who has parsed XML knows the pain of parsing. Actionscrip in Flex 2 contains Ecmascript or E4X for XML. It makes it easy to manipulate a XML object by treating XML as a primitive variable. Take a look at these simple examples.

◆ no longer has the pain of layout interface

We've all been through this pain before. Anyone who is keen on using CSS layouts knows the pain of trying to lay out those DIV tags properly. It's really painful. The advantage of Flex is that it is very easy to transform fixed and liquid layout designs into desired layout results by using container-based Flex markup language (MXML).

◆ simple domain authentication

Anyone who has created a business program or e-commerce application has handled form field validation. Postal Code. Credit card number. These are built-in in Flex and are easy to use.

◆ 's rich media support

The Flash platform completely loses the advantage of the previously dominant Web Media player (Real,Windows Media). The Flash platform is lightweight and does not require anything to be installed at work. Flex makes it easy to embed audio or video content in the right place in your program.

◆ realizes the real separation of presentation layer and content.

For years, developers have been talking about the advantages of separating data from the presentation layer. Of course, in the Web world, it's easier said than done. The vast majority of web applications are templates associated with some form of dynamic content. The advantage of Flex also lies in the use of Flex, which can cleverly pull data from anywhere (simple XML,SOAP, etc.) and help it to elements in the interface. Doing so can promote stricter separation. Your server only transmits data now. When you do this, you not only have an application, you also have an API.

◆ Flex development environment

All Javascript developers know the pain of developing AJAX/JS applications. Debugging is a tiresome task and there is no visual development environment for AJAX/Javascript. Flex Builder 2 is a visual programming environment for Flex, which is an industrial IDE like Visual Studio and Jbuilder. It is based on the Eclipse IDE platform.

◆ CSS support

We have got some serious CSS geniuses at Arc90, and we are pleased to see that many styles of Flex are also controlled by CSS. Color. Font. Inclination. The advantage of Flex is that those CSS techniques can still be applied to skins and custom Flex applications. You can see that Flex Style Explorer has a simple understanding of Flex's CSS.

Deployment of ◆ Web archive files

Package and deploy the Flex application into a standard WAR file on a J2EE server or in a servlet container.
