Is it possible to request data from the server after a webpage is done loading?
What I am curious about is if web pages can request data from the server
after a web page is done loading.
What I noticed is that for example on twitter there are tweets displayed as if
they come in in real time, is the webpage actually getting this data from the server at real time?
I knowit’s possible if the user has a java client or something installed,
but s it possible using only javascript or default languages without the user downloading anything?
where can I found more information on this?
Thanx in advance!
Yes it is called AJAX – Asynchronous Javascript and XML. A web page has a piece of Javascript that requests updates. This side of things on the client side uses plain and simple javascript, the user doesn’t need any special requirements for it to work. Server side your web page needs to be built with an AJAX implementation, either by using an AJAX module in Apache if you run the server yourself or by using a hosting provider that supports AJAX. The only requirements here are on the server side for you the designer to worry about – the user themselves only needs a web browser that supports plain old javascript.
