Building new technologies with old knowledge -- AJAX learning summary and new technology -- ajax

AJAX is a new technology that brings old knowledge into the container of new ideas: a technology that overwrites the design technology of traditional web pages and improves user experience.

At the beginning of learning AJAX, I wrote an article titled the first encounter with Ajax. Both of them are just some simple understandings. This time, we will summarize its important position in the history.

AJAX is called Asnychronous JavaScript And XML, And the so-called "old knowledge" is html, XML, JavaScript, And even the previous css.

AJAX includes the following technologies:

Use DOM for Dynamic Display and interaction,

Use XML and xslt for data exchange and processing,

Use XMLHttpRequest for asynchronous data retrieval to implement local update.

Use JavaScript or jQuery code library to integrate all the above technologies to achieve a new user experience.

◆ In terms of threads, AJAX changes the single thread of the traditional web, changes the notification method, and reduces the waiting time returned by the notification:

◆ In terms of the application mode, AJAX is added to the AJAX engine. XML reduces the coupling between servers and browsers, and XML serves as the data carrier for communication between clients and servers, host browser requests and store the information returned by the server.

◆ In terms of user experience and development thinking, AJAX not only improves the user experience, but also gradually tends to standard development and layout.

AJAX integrates old knowledge to make the best use of it and provides a better user experience.
