The Development of Flex and Web Application

Contact Flex technology

As a sharp tool to develop Web applications, Flex technology has been paid more and more attention in recent years. In this paper, we will explain the role of Web technology from the perspective of Flex application development. At the same time, some important concepts in Flex technology are explained.

The Development of 1.Flex and Web Application

The popularity of the Internet is only a little more than ten years, and it has developed rapidly from the initial browsing of static information to dynamic search and multimedia applications. With the progress of network software and hardware technology, most of the digital information applications can be realized through network mode.

All kinds of network applications running on the network can be called Web applications. The following describes the development direction of Web applications from the point of view of users (users) and developers.

1.1 users' expectations for Web applications

At present, the main purpose of most netizens to get online is to obtain information through the Internet. With the progress of network technology, access to information is no longer a problem, we begin to pay attention to the network "experience", to make the process of surfing the Internet a kind of enjoyment, especially in terms of vision and operation.

How to provide more attractive visual effects of Web applications and how to make the operation more user-friendly and interesting are all areas that need to be improved.

Users are full of expectations for online life, we can boldly imagine: with the progress of science and technology, the future Web applications can provide people with most of the content they need in daily life. Moreover, we can get a full range of sensory experiences such as sight, hearing, taste, smell and so on from Web applications.

1.2 developers' expectations for development technology

PHP, ASP, JSP and so on are commonly used client (browser) technologies for developing Web applications. They are all scripting languages and need to rely on the browser's dynamic interpretation to display and execute normally. The non-WYSIWYG development approach makes code debugging difficult. In the development process of Web application, the debugging of interface appearance is very time-consuming, and the same code often has different appearance and different action effects in different browsers and different versions of the same browser. Developers are looking forward to the emergence of solutions to the above problems.

The interface written by scripting language has limited expressive power, and most of them are static effects, which is where Web applications need to be improved.

New atmosphere brought by 1.3Flex

What improvements can Flex technology bring to Web applications?

As far as the current development stage of Web application is concerned, what network technology can do is still limited, and it is impossible to develop like a great leap forward. Looking at the present, we consider improving Web applications from two aspects: enriching the content of Web applications and improving user experience.

Enriching the content of Web applications is an eternal topic and is not included in this book. We mainly talk about how to improve the user experience through technical means.

If you have come into contact with Flash, you know that it has a strong visual expression, and the dynamic effect is very good. Flex is the sister of Flash, and it also has very powerful functions. As a sharp tool for developing Web applications, it is worth looking forward to.

For developers, using Flex to develop Web applications can thoroughly realize the architecture idea of MVC and completely separate the logic of user operation from the server-side code. This can greatly simplify the complexity of the system architecture and have an essential impact on the design of future Web applications.

The objects developed by Flex are files with the extension swf, which are interpreted and executed by the browser's plug-in FlashPlayer (runtime environment). Because the swf file is compiled intermediate code, the source code is not visible, and security is improved another level.

All kinds of advantages of Flex technology make it come into the vision of developers. It is also seen more and more in practical Web applications.

Thank you for reading! This is the end of this article on "how is the development of Flex and Web applications?". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, you can share it for more people to see!
