ajax in the dark age
By Weijun on May 25, 2005
ajax is hot these days, since the named was coined 3 months ago. but i really have done it several years ago, maybe around 2000, when i have no idea about what XMLHttpRequest is.
back them i am still on the dark side, writing applications for MS-Windows. i am working in a company writing softwares for stock market technical analysis tools. the other guys in the company uses Visual C++ to write MFC programs of windows and dialogs and drawing sophisticated graphs with CDC things. i am working on the server side, generating all kinds of data that the client can request. my codes end rather early and i also write the test. it is a very long html file, on which many links representing all kinds of data available from the server, including quote snapshot, all observed deals, price every minute, price every day, splits, dividends, and so on... clicking on each link will show a full page of data, in the comma seperated value format. it looks ugly, full of digits. anyway, it looks enough, and i pass it to the test guys and the client side coders.
i don't remember why it didn't finally change into a real application. maybe it needs more bandwidth than a fat client (which can use binary encoded or even compressed data). maybe the function is still far from complete. or maybe it can only be promoted as a free tool. or, maybe Internet Explorer is too reluctant to free memories allocated on a fixed page and will crash after 5 or more stocks.
