Streaming XML With AJAX
Dec 6, 2006
Is it possible to stream XML data from a file using AJAX?
The xml file is constantly being updated by a backend program, I currently have a javascript that has a timer, every second it just runs a loadXML() function to return the XML data however having a few problems with the javascript tripping over itself.
Wondering if AJAX has streaming abilities?
Also, can someone please clarify for me, is the xml dom javascript, or ajax? As I have just read a ajax book that tells you to use xmldom to read xml data but im already doing that, with javascript, what is the difference?

I have a streaming audio feature set up using a M3u file and a bunch of
MP3's: http://www.motorcityrock.com/mcr_radio/mcr_radio.html. When then
visitor clicks on the link the M3u kicks in and the songs play in the
pre-determined order. That works great, but everytime a visitor clicks the
link the songs start from the beginning. Is there a simple way (using
Javascript or?) to keep the M3u "running" in the background all the time so
that all visitors will hear the same song at the same time...just like a
traditional radio station?

I am playing with the XMLHTTPRequest method to perform client/server
transactions. I have it set up right now so that when readyState is 4,
it takes the XML and processes it. This works great until there is alot
of data. In that case, the user will have to wait for the data to come
back which may take a minute or so.
I don't want the user to have to wait. Is it possible for javascript to
periodically (while still receiving more data) stop and display what it
has received thus far? I guess this would be considered a type of
streaming.
In mozilla/firefox, I have read that I can use readyState 3 to run my
callback function every 4096 bytes. I can then take those 4K, parse
them, and then continue on. However I have also read that IE cannot do
this. Since I need this to work in IE, is there a workaround?

I wanna play streaming audio (an asx.file) trough javascript. I allready found a tutorial on the net. Till so far it works (I can push play, pause and stop), but I want to change the volume to. An example: Code:
Do you know where the problem is? One thing that I must say is that the tutorial (where I took it from) worked with a wav-file, as you can see I work with a streaming file (asx-file).

I am going to use the server push
for streaming the data by keeping the connection open. At client side,
i am having the XMhttprequest object (i.e ActiveX object of IE). When
the data comes, onreadystatechange method get callback on state 3 but
it doesn't allow me to read the data from the object. It says 'The data
necessary to complete this operation is not yet available'. Is it
possible to read the streaming data from the XMLHttprequest object in
IE?
I know Mozilla supports to read the data, when the ready state is 3. In
Internet Explorer, how we can use the XMLhttp Active object to read the
streaming data.

I need to allow user to download mp3 files when they click on the link rather than streaming the audio in the browser. Need to use only Javascript to download the file.

I'm looking to duplicate the video-embedding technique shown on revision5.com, whereby they show the flash video to all platforms where flash is available, and only show the HTML5 player on mobile devices. Is there a browser-sniffing framework, or some other method available to accomplish this?

I'm creating an AJAX page that is built using a PHP Class, ie the php looks a bit like this: PHP Code:
$wp_page->addjs('../var/savepolicies.js')
$wp_parser->page = "userpolicywindow.php";
$wp_parser->addlink("Home","../index.php","");
$wp_parser->addlink("Logout","javascript:logout();","");
$wp_parser->getpageid("501");
[Code]...
within this page that has been created, there is an AJAX tree folder which calls another page to be loaded into a DIV by AJAX again. Code:
[Code]...
I don't know why it doesn't work because the page has been loaded with the JS file, but as soon as the link is added afterwards it doesn't work. I take it this is because it doesn't know where to find the JS, but how can I overcome this?

jquery provides ajaxStart() and ajaxStop() events. Those two events do not seem to be triggered if the ajax requests are made by Microsoft Ajax tool Kit (from ASP.Net code). Is there any way to bridge those two event models? If not currently possible, is there any future initiative or plan out there to make this happen?

i have a series of <select> fields. The first one, via ajax(), generates a 2nd one, based on the first ones' data with the .change() method. there is then a 3rd <select> - who's data will depend on choice of the second one although step 1 works, and i can generate the 2nd one, i still can't generate the 3rd one.
when i test the script on its own, both the 2nd and 3rd <select> fields are fine - but not via the ajax, which leads me to believe that the .change() from the 2nd one, isnt triggering the ajax call - its not being picked up (even the 'hello' alert isnt working).

Am trying to set up a very simple AJAX script for my website. The
javascript i have in an external file which reads as below.
This works perfectly in firefox but IE doesn't display anything at all.
No error messages, just a blank IE window. If you look at the IE source
this html is all there it just won't show it! Code:

I was playing a little bit with a lot of ajax frameworks. I have even
wrote one small by myself. But one thing still drives me crazy: Whenever
I'm doing an ajax call I need to specify handler to handle data coming
from a server script. That means that almost for every action I need two
functions.
Since I'm still new to all of this I'd like to ask how can i achieve
something like this:
function function_name(el) {
var i_need_this = get_what_i_need(el.id);
return _i_need_this;
}
where get_what_i_need function is returning some information using ajax
from a server.

I've noticed a strange behavior with Ajax in internet explorer. In my page I've four links, that call four different pages by using XMLHttpMethod. By entering for the first time in the page and selecting the various links, all work correctly (the 4 pages are called and displayed into the page), but if I click again on a link previously clicked, trying to repeat the call, the responseText won't to appear!

In particular, there is a pretty nifty little box effect that seems to be popping up all over the place these days. It would work perfectly for a project I am working on, but I have no idea how to go about doing it.
I found a joomla template over here that has just what I want. I don't use Joomla, I'm a wordpress boy, and I also don't really want to dig in there and rip it out. Could someone look at the template and possibly point me in a direction on finding something similar to that? Possibly something easy? Code:

I'm currently engaged on a dissertation which is
investigating AJAX technologies and I was
wondering if anyone had any references that might
shed light on the subject?
I will of course carry out a literature review but
in the mean-time has anyone any (preferably print
based) sources of data on AJAX?
