Getting started with Ajax-accumulated experience

Getting started with Ajax-accumulated experience

After each course, I will always write a few words to summarize the course content. This is not just a review of the core Ajax technology mentioned by Mr. Wang xingkui. There is not much content in this set of videos. I briefly explained the XMLHttpRequest technology, Dom and its knowledge of HTML, XML, and some JavaScript operations, and finally completed it through two comprehensive examples.

XMLHTTPRequest object

For more information about the specific meaning of this object, see my previous blog-Ajax getting started-attributes and methods of XMLHttpRequest object and Ajax getting started-use XMLHTTPRequest object in five steps. These two blogs provide a detailed introduction to the XMLHTTPRequest object.

Dom basics and operations of HTML and XML

About the basic knowledge of Dom, Dom operation HTML has been briefly described in the previous blog "ajax entry-dom operation html.

Dom-based XML operations are the same as HTML operations. You can use Dom APIs to retrieve and modify XML operations (the exercise source code will be attached later ). Note that the document special object only corresponds to the HTML root node. The XML root node must be obtained after the xml dom object in a certain way.

In this part of the video, we solved the blank information problem caused by browser differences, and learned how to serialize DOM objects into strings that represent XML, learn about and use XPath Technology (insert, search, and expression writing in different browsers ).

Advanced javascript technology

This section describes how to encapsulate arrays in Javascript, object creation, JSON data format, JavaScript object-oriented objects, and XMLHttpRequest objects. Class, Public Private attributes and methods, prototype objects, parent-child inheritance, interfaces, reflection, and namespaces. If you have a lot of design knowledge, you need to learn it yourself.

The use of JSON data format was mentioned in the previous blog ASP. NET --- general processing program. The link to this blog post contains the relevant source code for download. You can refer to it for details.

Postscript

watching this video is not the end of Ajax learning. It is the beginning of learning. If the video capacity is limited, you need to look at other relevant materials. At the same time, no matter what you learn, the ultimate goal is to use the relevant knowledge in the project as soon as possible.
