I have seen web pages sites, when you drop down a list box, it seems to go
back to the server to retrieve some data without reloading the whole page
(e.g. select make of car and it retrieves a list of models from the server
to populate another list box).
I want a certain JavaScript script to access an XML file on a different server.
I can use PHP or any other language needed if i have to. but the main file must be in JavaScript.
what I am trying to accomplish is done through javascript, but I think that it is.
I would like to access server-side data without refreshing the entire page. Is this done through layers somehow?
I have this problem in xsl wherein i want to access a variable in
javascript and use it my xsl. How would i access or use a javscript
variable in my xsl file?
I'm looking for a way to do:
function resetBorder(theObj) {
theObj.style.border = theObj.class.border;
}
But it doesn't seem to be as simple as that, I'd like a cross-browser solution, but will settle for IE.
Say I have a tag like this
<SCRIPT src="navbar.js?width=580"></SCRIPT>
This is just a very simplified example.
In my navbar.js file, how would I retrieve the arguments such as "width"?
ie
var width = /*?????*/;
document.write("<TABLE width="+width+">");
I've been using some code to verify form data quite happily, but i've
recently changed the way my form is structured, and I can't get it to work
now.
Originally :
The form is called "form1", and I have selects called "PORTA", "PORTB" ...
etc...
I then had javascript that accessed these selects as below, and it worked
fine.
ind = document.form1.PORTD.selectedIndex;
val = document.form1.PORTD.options[ind].value;
dev = document.form1.PORTD.options[ind].text;
My form is now autogenerated, and form data is stored to file, so I now use
an associative array for thte form elements (so that I can loop through them
easily), The form elements names are now :
McuCfg[PORTA], McuCfg{PORTB} and so on
Now, I modified the javascript so that it now uses the McuCfg[] associative
array :
ind = document.form1.McuCfg[PORTD].selectedIndex;
val = document.form1.McuCfg[PORTD].options[ind].value;
dev = document.form1.McuCfg[PORTD].options[ind].text;
When the script runs, I get the error
"document.form1.McuCfg.PORTD is null or not an object"
I have used the same notation that i know works for the "options" array
although that's not an associative array.
In my HTML, I have several of the following:
<input type='checkbox' name='right[]' id='right[]' value=Ɔ' />
All are the same except the value is set differently for each one. The
reason for the [] is so I can access the checkbox values as an array on
the processing page (when clicking 'Submit');
However, I want my Javascript code to examine these objects first. My
onclick event handler function (below) is called (I get the 'hi there'
popup), but it does nothing afterward (i.e., neither 'checkbox' alert
appears, and the handler, strangely, seems to return 'true').
I suppose my problem is that I am not specifying the checkbox array
properly. I tried several variations, but I've been working on this
problem alone for several hours and am getting nowhere. Code:
I'm, having some problems with this function.
function displayElements()
{
for (i=0;i<document.forms[0].elements.length; ++i)
{
document.writeln(document.forms[0].elements[i].value);
}
}
I'm trying to loop through the only form (form[0]?) on my webpage and
display all their values. For some reason I'm only being shown the first
value?
Is it possible to get the web - server name through Javascript? If yes, how?
My code goes as follows. I get an error after executing this
<html>
<head>
<title>Untitled</title>
<script>
function disp()
{
str1 = location.host();
alert(str1);
}
</script>
</head>
<body>
<cfoutput>
<a href="##" onclick="disp();">Click me</a>
</cfoutput>
<cfabort>
</body>
</html>
The scenario is of two different web servers. The parent frame (html
page orginates from server 1) has script like
function x1()
{
.....
alert('parent invoked');
....
}
Inside child frame (html orginates from server 2) the html refers to
parent script like
{
.....
parent.x1();
....
}
It throws Microsoft Jscript runtime error: permission denied. I am
using IE based on WinCE 4.2 version platform.
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'd like to implement a server socket in java: something linke the following example.
The problem is that the HTML has not the permission to execute instruction
serverSocket = Components.classes["@mozilla.org/network/server-socket;1"].
createInstance(Components.interfaces.nsIServerSock et);
Question:
1 - how do I give it this permisison?
2 - one solution I thought was to put the javascript code in a firefox
extension, to load, so it should have all needed permisison, but,
How can I call a java script function define in an extension
from an html page? - there's some particular syntax? ....
I have three different web pages with different domains, and I want to
show some pages of one of the webs in the others.
I use an iframe for this and it shows it good until I have to call a
javascript function in the iframe inside page, I have a permission
denied because the domains of these pages are different.
So, the cuestion is:
Is there some way to call the javascript function of the iframe from
the parent page?
The script below loads a calendar page in an iframe and scrolls to
today's date.
It works just dandy on my apache/linux server, but won't do anything
when I use IIS. (Nothing appears on the page at all where the script is
at.)
I'd appreciate any suggestions on how to make this work from the IIS
server. Code:
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 was handed a project that, when launched, had some ajax problems--specifically, "Error: uncaught exception: Permission denied to call method XMLHttpRequest.open." That's easy enough to fix--found the call in the .js file that was referencing the development server instead of the live server, and I am aware of Javascript's same-origin policy, which makes good clean sense. Change that call, problem solved.
Unfortunately, it's not solved. I can change the reference from
var url='http://www.devserver.com/function.php?id='+id;
to
var url='http://www.liveserver.org/function.php?id='+id;
but that doesn't solve the issue of if someone comes to the page without the 'www' or to the other domain, whose TLD is a .com instead of .org.
In PHP, I'd simply write the function to dynamically generate the url string, using $_SERVER variables rather than hardcoding the url. But I'm no javascript guy. Any help would be appreciated.
I'd rather not have to put a php redirect in every page to make sure the url is what I want it to be. I'd much rather learn something new about Javascript.
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.
Is it possible to get the Server IP Address from Javascript
ie., when the user types "http://10.0.0.10/main.htm" in the web
browser, i need to retrive the value of the IP Address(10.0.0.10) from
my client side javascript.
I want to populate my client's webpage (Remote Server) automatically
through my Server and Database by having him just paste a javascript
on his webpage.
I have read up about Microsoft Remote Scripting but the documentation
states the following : "The server which you make remote scripting
calls must be the same server from which you requested the client page
containing the requests."
In my case , the client and server pages are on two seperate servers
which means that I cannot use MS Remote Scripting.Is there an alternate
approach in any scripting language ???
Any suggestions, tutorials , websites , code snippets will be
appreciated while i continue to research on this...

Now that http://username:password@site.com no longer is an accepted
syntax in IE, I suddenly have a case in a project I'm working on. The easiest(?)
solution would now be that there was some Javascript function that
could pass the username and password or in som other way automate the login
process on a given site.
Thing is I have a server-generated HTML page that I want to make the
client redirect to a password protected site. (IIS Windows authentication).
Before: location.href='http://name:pwd@site.com'
Now: ?
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 am a .Net Developer. I want to know to write javascript for serverside controles.And where it is placed for sever sidr controls. Please tell me if any one know this.
