Why Do People Prefer Ajax Apps Over Java Applets?
Sep 21, 2006From the common user perspective (like my grandma), why would they care
if its a java applet or an ajax application? Say I want to make a chat
system on my website...If i'm doing really involved Comet push-style
data communication, and rendering everything using DHTML, why would
users prefer that over a java applet?
Moreover, say I use a java applet to transfer data through a socket
connection, then use DHTML to display the data, so that basically the
front end is the same, but the backend is differs, why would a user
prefer the comet-style programming over applet?
I'm asking because I wrote an Ajax chat system through polling, and I
want to switch to a Comet push-style system because polling just isn't
responsive enough. I want to know if I can avoid Comet (since it is
alot of overhead for the server) and just use an applet in the
background to transfer data through socket connections, then use DHTML
to render the chat boxes.
Call A Java Method From Javascript
Jun 5, 2006I am trying to call a java method from within my Javascript, but cannot
seem to get it to work. All the examples I have found online and in
the forums are using Java applets. I have a method that I want to call
that does a search, and produces a message dialog displaying the
results. Also, the class file lives next to the html file. How would
I invoke this in my code? This is what I have now:
<script>
function searchStrings(){
Searcher.search();
}
</script>
<form>
<input type="button" value="Search" onclick=searchStrings()>
</form>

Java Vs Javascript For AJAX?
Jan 19, 2007I am a XHTML/CSS developer with an interest in AJAX. I am at the stage were I wish to learn how it's all done.
So my quesiton is this:

It may sound like a dumb question considering AJAX is mainly javascript and XML, however will learning JAVA first off be a benefit?
Script For Switching Between Two Applets
Jul 23, 2005I have 2 web cameras that are displayed in my html page by two different
applets. I did not write the appletts, I just put them into the web page.
Question 1: Is there a way to have this image on the page change from one
camera to the other every 15 seconds?
Question 2: Is there a way to have the cameras only appear during a certain
time of the day and have a jpg appear the rest of the time - i.e. daylight
hours?
Camera #1
(I altered the actual link to the cameras.)
<applet name="cvcs" codebase="http://x.x.x.x:80/" code="xplug.class"
width=320 height=240</td>
<param name="RemotePort" value="80">

<param name="RotateAngle" value=0>
<Param name="PreviewFrameRate" value=2>
<param name="DeviceserialNo" value="aGFyYm9yOm1hcmsxMjM=">
</applet>
Camera #2
<applet name="cvcs" codebase="http://x.x.x.x:81/" code="xplug.class"

Passing Arrays To Java From JavaScript
Jul 20, 2006This may be more of a Java question, but I feel that JavaScript experts
may be more qualified to help me find a solution.
In short: is it possible to call a Java method from JavaScript, passing
as an argument a JavaScript array (in my case, an array of doubles)?
Supposing I have array x containing only doubles, I have tried:
document.MyApplet.myMethod(x);
But the method only ever seems to receive "null" as an argument.
Conversely, if I try this with a String, or a single character, or
almost anything else, there isn't a problem. Any ideas?
Communication Between Java Applet And Javascript
Jul 20, 2005let's me explains my long problem:
I'm doing an intranet with a media part. So im must be able to upload files on
a ftp server AND have a record of informations about this file and meta date in
a MySQL database, shown in a php page.
So the first thing i was doing was:
1/ * A HTML Form, with a <input type="file"> which was uploading the file to
the web server. And then, in the next action-php-page, using ftp functions from
php to upload to the ftp server. But this make upload the file 2 times, which
slow, and the user can't do anythig except waiting in front of a blanck loading
page.
=> no way
(BTW, the site admin refuse that the ftp server and the web server to be the
same computer)
So i tried something else:
2/ * A HTML form, the user enter meta data about the media, click next, and
then, a php page which loads a java applet an pass informations to it (by param
tags).
The applet have a browse button, and a go button, which start the transfert
(JDK 1.4.1) trough the URLConnection. The file is uploaded once, and there is a
progress bar, which is wonderful.
But now, i need the src_file information wich is the java applet. So i have two
options:
A/ I make a post to the webserver from the applet. But i'm using session
identification (needed for tracing users actions) and i'm gonna use SSL in less
than one month, so i think it would be complicated.
B/ I export the information from the java applet to javascript, and then to
HTML hidden field, so that the user can submit the full-hidden-filled form. But
i can't make LiveConnect works.
i'm under Mac OS X 10.2 (jaguar) so i need to make work LiveConnect on both
Safari 1.0 (v85.6), mozilla 1.5, and Mac OS IE (5.2).

Java Applet Verses JavaScript For Scrolling Text
Jun 24, 2002I am looking at a client’s site that has a scrolling text bar at the bottom of the page for latest news. I have been asked to recommend whether they keep the scrolling text as a java applet or whether they make it dhtml with Javascript to make it scroll.
To be honest, I’m not sure whether there really is an important difference, in terms of download time, likelihood of working (if client browsers are better enabled for one verses the other), or whether there are any other reasons one should be used over the other.

Feb 3, 2006I am very new to this and have just written some code to randomly generate an image on my web page. Each time I test it, a bar at the top of the page comes up saying:

How do I stop this coming up on other peoples computers, because if they don't click OK, they can't see my images? Is it my script that is causing an issue, or is there a simple fix for this?

How Can We Stop IE From Executing Javascript On A Back Button Click
Nov 14, 2007Basically, I have a page that I load with 10 input fields. If users
have JS enabled I want to hide 5 of these fields so as to reduce
clutter. If the user needs these extra fields an "Add" button can be
used to display the hidden fields one by one.
Once the fields a filled in the user submits them for validation and
if there are any error They can "Go back" to make some changes. The
whole process works great in FF & Opera but IE lets me down because if
you use the Browser "Back" button the Javavscript gets executed even
though it should be loaded out of cache.
On Javascript Replace Method.
Jul 29, 2007I don't think this is "do-able" but thought I'd better check. Say I
want to replace certain names in some source code as long as they are
not properties (dot properties) of objects. I could use a regular
expression like:
rx = /(?:(.)|)(?:name1|name2|name3)/g;
map = [];
map["name1"] = "a";
map["name2"] = "b";
map["name3"] = "c";
source = source.replace(rx, function ($0, $1) {return $1?
$0:map[$0]});
Dot properties like .name1 are not replaced by anything new and they
need to be "skipped" over by this regular expression but other name1
identifiers need replacement with "a".
One problem with this approach is that dot properties like .name1 are
replaced by themselves and this is just unnecessary work. Something
like a "false" return to skip replacement would be nice but the
following doesn't work.
source = source.replace(rx, function ($0, $1) {return $1?
false:map[$0]});
There are other ways to get around this by using something else
besides replace() but I wanted to see if it could be done with the
replace() method.

Turning Form Actions On And Off With Javascript Or Some Tother Method
Oct 28, 2000Does anybody know how to turn off form actions please?
I have 2 types of users (members and non-members) using the same form action. This form has 4 buttons in total.
If the user is a member they have full access to all buttons.
If the user is a non-member they can only use 2 of the 4 buttons.
So, at the moment, when they are non-members and click on one of the members buttons, an OnClick event handler is added to the input type = "submit", which generates a new window with a document explaining to the user that they need to register.
There is no problem generating this window.
The problem is that the form specified in the form action still executes and the members page is still displayed.
So is it possible to turn off the form action in this instance so that the main page isn't refreshed/executed, or do I have to create different form actions for different users.
Surely there must be a way to prevent the form action from being triggered?
I realise I could simply not display the button for non-members, but I'd prefer to do so, as it allows them to see the features that members receive.
