Is AJAX Server-side Independent Concept??
Oct 31, 2006
AJAX is a rich client-side technology that makes the web pages more
interactive. In practice, the same AJAX client-side code should be
unchanged, regardless of what server-side web technologies we use. I
guess this is same concept as traditional front-end plain html code
that can work with different server-side web technologies for back-end
processing.
Similarly, AJAX should be server-side independent concept,
is that correct? But if this is the case, why there are different AJAX
frameworks available for different server-side web technologies such as
Java, PHP? We should simply just use generic AJAX server-side
independent framework for our AJAX-enabled web applications.
I wonder what server-side technologies that google maps/gmail use for
their AJAX front-end?? I guess google maps/gmail can be good AJAX
models to follow?? What do you think?

I'd been looking for some way to get server date/time without using any server side script (such as ASP, PHP, etc).
I found this and it worked just excellent for me! I just want to share it because it wasn't easy to find.
I created a js document with code:
Code:
Now, I can use this js within a html like this:
HTML Code:
You may change your machine date/time and check both dates.

I want to load some pages generated with the server (ASP) and assign
their html results to JavaScript, so users could click the links and
the content of any selected page would show up immediately, making no
requests.
So, I have one main page called mainpage.asp which, I think, should
get all subpages with content, names are subpage1.asp, subpage2.asp,
etc. I tried ASP's XMLHttpRequest to get content of all sub pages and
assign html result to JavaScript variables. But I realized that MS
XMLHttpRequest does not get session protected pages. I mean that if my
subpage will generate output with session only, then even if the
session exists, MS XMLHttpRequest does not see it.
Anyway, this trick did not work. If I include these subpages in
mainpage.asp under a hidden field, this may be a solution but I do not
see it good enough yet.
What would you recommend? How would you assign subpage's html code to
JavaScript variables or array of variables?

My login to the site is being processed using ajax, which does a redirect to the members page upon succesfull loggin in.The login feature however can in fact take a while because we need to initialise quite some data when a user logs in (his details, but also his privileges are loaded, his personal menu based on these privileges are being loaded, we are loading shopping cart info, we are initialising personalisation settings, and a whole lot more.It sounds like a big thing, but it isn't, and once logged in, the application is going great. the only thing is that the login proceure can take 3 - 4 seconds, and I would like to be able to show the client the progress of the serverside script:
"Searching your account..."
"Validating your privileges"
"Initialising your personal menu"
blablabla...
To do this, I might just call an ajax call that starts the login procedure, and then issue another ajax call every 1 second or so to update the status based on some session variables I set in the login procedure and that I can serve to the client when th next ajax calls come in, but I would love for this to work a little nicer as in just needing to initialise ONE ajax call which can send back statusupdates from the server...

I am trying to write a string variable containing XML in the form of text into an iframe such that it shows up as formatted XML with the expand(+) and collapse (-) options that default in IE when opening an XML file.
The first thing I tried is writing the string to a file with .xml extension and setting the iFrame src to that file. This works well normally, however in this case, the file does not get created where I want to due to some security restrictions in IE which I cannot edit as I dont have admin rights.
Secondly I tried appending the string as innerHTML to that iframe but only the content within the XML tags without any formatting shows up which is not intended.
Thirdly I cannot use any server side scripting as this is a very controlled environment and I am not allowed to host servers or edit server scripts at will. This is totally out of question, so I guess Ajax or calling a costom defined web service wont help.
At best I can say, I am limited to HTML, Javascript and vbScript.
I am receiving the string as a responseText from an ajax request which is consuming a web service. If I use responseXML, it doesn't work.
The solution I am looking at is to either display it as formatted XML in an iFrame or to just throw it into a textarea which I am already doing and simultaneously write it to an XML file or do both. If not automatically, atleast have the user press a button and do it.

I want to send three text box values to server using jquery ajax. problem is that, i dont know the exact syntax to send three data. When i try sending one data(also change no.of parameters to one at server side method), its going good but when i try to send three text box values, its giving jquery error:"Internal server error". I think I am not sending data in correct way. Example below contains only two sending data, because i was trying to send 2 data first.
Below is the code:
function testCAll() {
$.ajax({
type: "POST",
url: "dbTest1.aspx/SendMessage",

I am building a client-side and server-side solution and want to use JSON through Ajax in both directions. I have ASP or JavaScript server-side, though Microsoft's support of server side JavaScript seems nil, so I am reluctantly conceeding to use ASP. I'd appreciate suggestions on available solutions to encode/decode JSON on the server-side (ASP or JavaScript). I don't plan to load jQuery server-side so that rules out plug-ins. I'd also like to know what is the latest client-side encode/decode for JSON. Is it built in jQuery or a plug-in? In both server and client, decoding JSON securely is key, so using eval () to decode is out.

I am developing a web form using python cgi which has two list boxes. On selecting a value from the listbox1, the list box 2 should get auto populated with appropriate values (which are taken from the DB). I have written a javascript function to get the selected value from the list box1. But I am struck with passing the values from the javascript to the python function written in server side in which I have written the DB related stuffs.

I have a Hyperlink within a String like below:
sSql = "SELECT DISTINCT " + "'Action' = '<center><a
href='+char(34)+'ChangeRequest.aspx?ID='+cast(Chan geRequest.ChangeRequest_ID
as nvarchar) +CHAR(34)+'>Open</a></center>',"
I want to invoke a Client side javascript function and pass the value
of the ID. How can I accomplish this such when a user clicks "Open" he
goes to a new window with the same ID.
I tried this but it does not work:
On Server side:
sSql = "SELECT DISTINCT " + "'Action' = '<center><a href= 'javascript:
NewWindow('+cast(ChangeRequest.ChangeRequest_ID as nvarchar)+
CHAR(34)+)'>Open</a></center>',"
On Client side:
function NewWindow(myID)
{
window.open("ChangeRequest.aspx?ID="+myID,"WindowName","width=500,height=600");
}
</script>

I have the following PHP code, which uses server-side validation, which works fine. It the user leaves the text field empty it stores an error in a session array which is outputted on the page where the $_GET['id'] variable came from. I also implemented a snippet of javascript code that just checks to see if the cell is empty and throws up alert box. The problem is that both the javascript code and php error validation are both running when I click submit. The PHP code should be a backup to the javascript code in case the user has javascript turned off. The client-side validation should be the default. Not sure if this change should be made in my PHP Code or Javascript Code.
PHP CODE:
session_start();
require_once("../Modules/Connection_Functions.php");[code].....

I have a web form that has a checkbox on it and a textbox associated
with it. I want the textbox to be displayed when the checkbox is checked
and I want this to happen on the client-side instead of posting back to
the server. The checkbox is a server control (asp:checkbox...). I can
write some codebehind that will display an alert message upon checking
the box that looks something like this...
Page_Load...
Dim s As String
Dim scriptString As New System.Text.StringBuilder
chkExpDate.Attributes.Add("onclick", "alertmsg()")
scriptString.Append("<script language=JavaScript> function alertmsg()
{")
scriptString.Append("alert('hi'); }<")
scriptstring.Append("/" + "script>"
s = scriptstring.ToString()
Page.RegisterStartupScript("startup", s)
End Sub
I used this as a test to make sure the server control was running the
script. But, when I change the script to assess the value of the server
control checkbox such as checked = true, I get errors and if I just try
to display the asp:textbox, it doesn't work either.

However, this piece of Javascript uses some other script which is large.
<script src = "./js/tmp.js".....>
This will work if the file "tmp.js" is local. However this reduces the
portability of my *utility* Javascript
as users have to have that "tmp.js" for every webpage they have (if they
want to use it :D)
I thought of uploading "tmp.js" it to somewhere and change my code to
<script src = http://www.somewhere.com/js/tmp.js ....>
The all the users have to do is copy the piece of code that I wrote
BUT THIS DOES NOT WORK. I TRIED IT.
My questions are:
1. Is there something wrong with server-side Javascript? Or am I missing
something?
2. Is there another way to make my code portable?

I might be turning a corner today and seeing the light. I might still
be confused :)
If JavaScript is the language for the browser then why do servers use
Ruby/Rails, Perl/Catalyst, Python/Turbogears or PHP/Cake? Is it because
the prototype-based language is too different to be chosen except when
necessary. Is it because browser bugs make people think JavaScript is
bad? Is JavaScript not suitable for the server-side for any reason?
I imagine that if server-side programmers started to learn JavaScript
then the client-side code in the world might start to improve.
Translation layer libraries like Prototype.js or Mochikit wouldn't need
to exist. The more I learn about JavaScript the more I like it. It is
difficult to learn however for multiple reasons.

Does Javascript work "out of the box with IIS" as an
Active server page? ie. does it have the ability to open files
ect.?
I tried this command and it does not seem to work.
var fileSys;
var txtFile;
fileSys = new ActiveXObject("Scripting.FileSystemObject");
txtFile = fileSys.OpenTextFile("./junk.txt",1,false);
I can't find examples on the web. What would I search for to find out
about objects the Scripting.FileSystemObject?
Background:
I work at a large company with a corperate IT group.
I need to write some server side scripts. The servers they
have are Windows 2000 with IIS installed. If additional
software needs to be installed I will be forced to use VBscript.

I'd like to adapt some Greasemonkey scripts that I've written and have
them applied to html files on the server side before the files are sent
to users. I'm only looking at adapting scripts that make static
changes to pages. For instance, consider a script that removes from
the DOM any img that has "ad" in its src.
I'm sure there are better ways to do this and I'm not even necessarily
looking for an extremely efficient solution. Mostly, I just want to
know if there's an existing product that could do this or with
reasonable effort could be made to do this.

I want control a hardware device using a Web browser.
I created a page which has a form containing all necessary INPUTs.
By clicking a button, all current settings are sent to the server side
(using POST or GET) so that the server can interact with the hardware,
which is under the server's control.
Now, in some cases, I want to update the INPUT (w/ readonly) with the
data from the hardware, such as a status value.
Most primitive approach is creating a new page with new value to the
INPUT, where I want to show the value.
But that is not quite efficient as the page appearance won't change
except the contents of the INPUT.
As Javascript can make any change to the HTML page (at client's side)
that is currently being displayed, it is more straight forward if the
server can send a set of Javascript commands to the web server so that
it can just update the display contents rather than refreshing
everything.
I thought such scheme was already available, but so far, I don't see
anything usable.
The Web server is not a commercial one but a custom Web server
(written in Python) so that I want to keep the scheme as simple as
possible. I checked AJAX but I'm not sure I can use AJAX in my
application.

I have a form field that needs to be validated in a hidden Iframe which is driven by Coldfusion. Which is working fine. But the same form field also need do some client side validation as well if Server side (iframe) validation passes.I thought I could create a javascript function, in it call a server side validate and then client side, but without any success. It does not process in the order as expected. Javascript always go first, then the server side validation.I tried to delay the client side with time delay, then server side did process first, but client function could not recognize the parameter passed.here is the function:
Function doValidation(param1,param2,param3,param4)

Now here's the problem, I've been trying to write a function where can define a folder "gallery est", and then get all image files in that folder and repopulate the slideshow array. So, is there a way to scan folders? I've searched around and found some solutions where PHP is used, but i really want to keep this pure js, if possible (?)

I have a TreeView populated from a SQL Server database (via an XML doc). The TreeView includes checkboxes on each branch and leaf. Each entry on the TreeView may or may not inherit access permission from its parent. That is, if you're granted access to branch "A", you automatically get permission to leaves "A1", "A2", and "A4", but not to "A3", as its inheritance flag is set to false.I have created an array of struct's on the server-side.
Struct format is:
public struct TreeInheritData
{
public Int32 namespaceID; // this identifies the node
[code]...
The array is populated with these structs.The TreeView I'm using (from Infragistics) has a client-side event when the CheckBox status changes.So, what I need help on is getting this array of structs from the server to the JavaScript, and then being able to access the structs so that I can determine whether to change the status of the child nodes' checkboxes.
