W1-My understanding of AJAX
I began to learn something about AJAX because we are going to use AJAX to do a project. I know very little of it before, Is it a simple technology or a complicated one?? Well, as I search the internet, a lot of information about AJAX, AJAX is not a sigle technolgy, it is a combination of many technologies (difficult to me). Why people like to use AJAX is that it will make the respond of website more quickly, User will save some time of waiting for the reply from the server. By using AJAX, the whole page does not need to be retrieved, instead, part of the page will change. I have tried many website and known many of today's web site are using such technology, as for the users, it is really good not to wait for too long for the whole page retrieved but the certain parts of the page. It shall be faster than befroe.
The Ajax technique uses a combination of:
1.XHTML (or HTML) and CSS, for marking up and styling information.
2.The DOM accessed with a client-side scripting language, especially ECMAS c r i p t implementations such as JavaS c r i p t and JS c r i p t, to dynamically display and interact with the information presented.
3.The XMLHttpRequest object is used to exchange data asynchronously with the web server. In some Ajax frameworks and in certain situations, an IFrame object is used instead of the XMLHttpRequest object to exchange data with the web server, and in other implementations, dynamically added script tags may be used.
4.XML is sometimes used as the format for transferring data between the server and client, although any format will work, including preformatted HTML, plain text, JSON and even EBML. These files may be created dynamically by some form of server-side scripting.
it is really a hard task to master AJAX, hoping I can get to know more about it in CS5281
