With the development of learning, the increase of content, the emergence of various languages, and the emergence of various scripting languages, there are also growing relationships between them, it can be said that many new technologies are developed on the basis of old technologies. Therefore, it is important to understand the relationship between them and their development. If we do not understand them, we will gradually confuse them, I would like to summarize some of the things I have learned. What are they? And what is the relationship between them? Let's take a look at the familiar and unfamiliar terms below, hoping to help you.
Currently, the following technologies are frequently used in BS development. Some of them have not been written due to incomplete learning.
HTML, Dom, DHTML, W3C, XHTML, XML, JavaScript, jquery, Ajax, CSS
First, let's take a look at JavaScript and jquery. Their relationships are the easiest to understand and have relatively independent functions. For JavaScript, read this blog (). For jquery, read this blog.
Secondly, Dom and W3C are both web programming standards. However, W3C is not a set of standards. It includes three aspects: structure) behavior and presentation correspond to their respective languages.
Structure: HTML, XML, DHTML, XHTML
Presentation: CSS
Behavior: Dom, ecmascript (JavaScript)
Ajax is a new idea rather than a new technology that integrates the above three aspects to improve user experience.
We can use the figure below to deepen our understanding:
Ajax is a browser technology independent of web server software. Ajax is based on the following web standards: Javascript
XML html
The web standards used by CSS in Ajax have been well defined and supported by all mainstream browsers. Ajax applications are independent of browsers and platforms. Web applications have many advantages over desktop applications. They can involve a wide range of users, which are easier to install, maintain, and develop. However, Internet applications are not as comprehensive and user-friendly as traditional desktop applications. Through Ajax, Internet applications can be improved and more friendly.
