Can Server Side Include Commands Have Javascript Ids?
Nov 14, 2006
can you put an id into a server side include like you can other items using javascript?
I tried this putting the id name in the virtual address area but it doesn't work. I also tried replacing virtual with id instead still with no luck.
document.getElementById('dynstuff').src=content[newm]
<!--#include virtual="dynstuff"--><!--#include virtual id="dynstuff"-->
The error message says getElementById is null or not an object but it works fine with image ids and iframe ids. Can anyone tell me why this doesn't work?

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>

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.

I have a number of server-side Javascript applications running on an
old Netscape Enterprise server. I want to move them to Apache. Is
there a way to do this without extensive recoding ? My code contains
a lot of Oracle and SQL Server database interaction.

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.

How portable is server side javascript? Does server side javascript works the same across different browsers and operating system? What I should do to ensure it is more portable?

I'm writing a program on Zimki, which I think uses SpiderMonkey as a server side Javascript engine.
My idea is to have an html file that someone else created, and look inside for cells in a table that have special known names, like name, description, etc. Then I want to figure out the <tr<tr/pair that encloses all of those special tags, and use that as a template to generate a bigger table from another datasource.
So, I'm wondering how I actually open a file and then parse it as html so I can poke around the DOM, all from the server side without involving a browser client.

I work for a financial company. I am planning to give a presentation
to rest of the development team (15 people) here on moving server side
logic to client-side javascript for an internal intranet application
rewrite. This approach will definitely stir up hot debate from
hardcore server-side Java folks who wants to do UI stuff even on the
server!. Since I am pretty much known as the JS or UI Guy of the
group, my Boss wants to hear the broad spectrum of PROs/CONs from each
proponent.
Personally, I think Javascript/Ruby is a more productive language than
Java.
My idea is simple. It is to convert most business logic to client-
side javascript and have calls to server-side code restricted to user
roles with data validation. Thats as simple as it gets.
Here are my list of arguments
1. True separation of UI logic from server-side data processing code
(no more server code spitting out client-side code)
2. Better user experience with faster response
3. The whole web 2.0 thing (no page refresh) :)
4. Offload client processing from server therefore reducing network
traffic (not really a strong argument is this?)
Keep in mind this is an internal app. Even if someone figures out the
JS logic behind the page and try to hack the app by posting to
Servlets, they will be restricted by their login role, and data
validation will take care of any bogus data being submitted.

I'm displaying a loggin page.
If the user entered an invalid UserName/Password I display the page again.
When this happens I want to give the user a different message then the one displayed when the page was initially displayed.
I use the Response.Redirect method from the page checking the submition.
When I do that I call the page with a parameter like this Response.Redirect("Page.asp?FROM=1").
When I get the parameter in the page I know I need to show a different message.
The problem is that if the page is called without the parameter, I
cannot determine that the parameter is missing.
The codse is very simple:
from_flag = Request.QueryString("FROM")
Now is the problem -
if I use if(from_flag == 'undefined') - this condition return
false.
but if I display from_flag using Response.Write(from_flag) I get "undefined"
if I use if(typeof from_flag == "undefined") - this does not work since the typeof return "object" in both cases when I call the page with the parameter or without the parameter.
also I tried to comnpare with null does not work.
By the way if I use VBScript as the script lang - it works fine I just need to compare the from_flag with vbNullString and all is well....

I have a few values and variables that I want to post to a server
(without using a SUBMIT button). Is there a way to post data from
within javascript - do sockets or connections have to be open for this

I am developing an ASP.NET (C#) application and need some help. I wish
to call a server-side function (in the code-behind "file.aspx.cs") upon
a user clicking on the "X" to close the browser window. Is there a way
to postback and call a server-side function when this happens? I am
aware of the browser's native "onunload" event, but am not certain that
what I'm looking for is actually possible.

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?

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 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.

protected override void RenderContents(HtmlTextWriter output)

output.Write(@"<table><tr><td>");

How can I make the button call the click event so that the server side method btnExecute_Click() can be called? Also, this button calls a javascript function before server side even.

So, I have a dynamic PHP file on my server. I want to make it so browsers can take the code I provide and paste it in an .html, .php, or .asp file, and it'll display across the board.
The file would need to be included, unless someone thinks there's a better way of doing this?
The only example I could think of would be Google Adsense's code? But I'm not sure.

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.

var frTraductionID = document.getElementById("frTraduction");
frTraductionID = (frTraductionID.contentWindow) ? frTraductionID.contentWindow : (frTraductionID.contentDocument.document) ?
