AJAX-Let yourself see the real web page, ajax-web page

I didn't feel any new about ajax at first, because I learned javaScript, XML, and DOM in B/S, so it is ajax knowledge to combine with ajax. This is what ajax says on the Internet.

1. Asynchronous javascript and XML, a Web Development Technology for creating interactive web applications.

2. A technology used to create a fast dynamic web page. By performing a small amount of data exchange with the server in the background, AJAX can implement asynchronous updates on webpages. This means that you can update a part of a webpage without reloading the entire webpage.

For case 2, we often encounter some items in our daily life. For example, when ajax is used, Baidu webpages are not updated, but only partially updated. Is it very convenient for users.

The learning knowledge must be associated with the learned knowledge. I have summarized some points.

1. ajax uses XMLHttpRequest for asynchronous data retrieval.

2. ajax uses XML and XSLT for data exchange and processing

3. ajax uses DOM for Dynamic Display and Interaction

4. ajax uses the standard-based Representation Technology of HTML and CSS.

5. Finally, all javascript technologies are integrated.

Technologies are old technologies. I feel that the biggest feature of ajax is that it achieves partial refresh innovation.

Next, we will understand synchronous web and asynchronous web as follows.

Comparison between traditional and ajax:

AJAX: The returned result is text data instead of a new html page. The returned result is returned to the user through the callback method registered in the ajax engine.

Traditionally, requests and responses are both completed through a browser and a new page is returned.

In the B/S stage, we can contact the B/S knowledge we have learned and compare the knowledge to have a deeper understanding of the new knowledge. Ajax is just getting started. Challenges Continue.
