Error While Calling Applet Methods From Javascript
Aug 9, 2005
The javascript fails to call an embeded applet's function. In the javascript
console, it shows "Error XXXX is not a function". Following are some parts of my code.
Here parent.document.cpmApplet and parent.BottomIframe.document.resultApplet are valid since I loaded both the applets with the same name using <APPLET> tag for Netscape/Mozilla and OBJECT tag for Windows.
The issue is with Netscape and Mozilla on Unix platforms only. I would appreciate if anyone could help me to solve this.
We have an applet that has to support the SUN VMs as well as the MS VM. The applet receives updates from a server (via tcp or http) and wraps them up as objects and passes them using the JSObject scripting context to a javascript function.
This function takes the object and reads the properties and updates a screen.
All seems simple stuff. The problem is that the MS JVM runs like a rocket, but the sun vm seems to max out our processor and also takes ages to process anything.
I have tried logging from the console using debug level 5, and it shows a lot of back and forth between the applet and the javascript when accessing methods on the object passed.
Seeing that as a possible problem, I now pass a delimited string to the front end, and then convert that into an update message purely in javascript so there is only one hit to the applet per message.
I am still seeing a massive difference between the sun and ms VMs.
Has anyone ever come across this, and is there anything I can do to help flatten out this performance?
I've previously written an image carousel with lightbox and to be honest forgot about it for quite a long time. I've just been tasked with making a few modifications (I wrote this code about 6 months ago)
Now, the problem I have is that I now need to call the internal method from the ligthbox plugin.
I've tried setting a reference to this like this but it just won't play ball. I can see that the ajax feed gets called but unfortunately I can't then access it.
QUESTION: How does one control the order in which jQuery methods are called and executed when loading a page? BACKGROUND: This question has been simplified from my previous question on load order. As this appears to be a complex issue -- otherwise, it would probably have been readily addressed -- I could likely be satisfied by a link or two that points to a well-written document on this topic. PREVIOUS QUESTION: [URL]
I have on a html page an applet. A javascript function call one function of this applet. It works with IE but not with Mozilla or Netscape. I obtain the following error on the java-plugin consol:
sun.plugin.liveconnect.OriginNotAllowedException: Javascript is not form the same origin as je java code ...
This is my html code:
<script language="Javascript"> <!-- function askServerCmd() { return document.AppReaderLink.askServerCmd();
How do I display a message applet is loading when a applet is getting loaded. Without using Mediatracker.I want the message to be provided as PARAM NAME.
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).
Does anyone know how you can test if an applet's method exists before you try and call it?
for example, if you don't have a JRE installed on your computer and try and access an applet method it shoots out a javascript error at you. I want to be able to test if the applet is operational basically before I try and use any of its methods.
I call methods in a Java applet with javascript code like this:
document.myApplet.methodName(); This works great when the applet has loaded (the JVM has started and dowloaded all the jars) but it fails if the applet hasn't loaded yet, at which point it gives an error: Quote:
Error: Object doesn't support this property or method
Is there a way to determine that the applet is loaded or not so that I can use it in an if statement? For instance, like so: Code: if (isAppletLoaded()) { document.myApplet.methodName(); } I tried Code: document.myApplet == null but that didn't work.
I 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.

It compiles; however, once I switch to the HTML window and try to run it, a screen appears and the status bar is giving me the "Start: applet not initialized error." Here's my HTML code:
I am trying to call a PageMethod and it is failing. I am trying to get the error message but I am not sure how to display it (I am trying to use the alert() function). I have tried alert(result) but all that is displayed is object [Object]. I have tried result.d, but that returns undefined.
In the code below the preFilladmin function creates a JavaScript error after leaving the admin_uid field
// Set this to your validation PHP script, default is "validate.php?value=" var vUrl = "/validate_assignIP.php?value="; // This is the array for error handling
This is the first time i'm really using javascript objects (well the first time i've written my own one) so the problem is probably a very simple one...
I've got this:
Code:
When i change the country from the dropdown box i get an error "hometown.setCities is not a function" but the thing is that i can call this in other ways eg from the address bar (javascript:hometown.setCities()) and it works perfectly.
I get error:Code: Your browser does not support XmlHttp Objects soapclient.js line 360 what is the correct way to call a web service in javascript (onLoad)...
the second file, soapcall2.html contains just the following (no <html/>,<head/> or <body/> tags)
<script> var ServiceUrl = '/ws/'; var CreateSession = ServiceUrl + 'general.asmx?op=CreateUserSession';

In IE 7/8 the error: event is triggered with the correct XML (XMLHttpRequest.responseText) but the textStatus reports parserror and the errorThrown returns [object error]. In firefox it runs without any problems and properly sets the sessiontoken variable.
i have used Div with in Div and tryed calling it from javascript, its workin fine with IE...but in firefox its not not..it says "document.getElementById has no properties for first case " n "frames has no properties for second case " in the javascript console within firefox... Code:
I have simple function that I call from an alert box
alert(testScore);
It works fine. Unfortunately, I do not like the sound and Exclamation point icon that appears. I'd like a nice message box like VBA message box #64 to appear. I know hardly anything at all about VB or VBA. But, I do know you can call a VB function from Javascript. How? Is it possible to get my testScores to appear from the VB function? Is it hard? Where do I start looking?
I have a page with an iframe. The page defines some JavaScript functions in the head part. How can I access these functions from the iframe? In Firefox I can use parent.myFunction() but it doesn't work in IE.
I am designing a template for File Hosting site but the flash uploader is breaking the design
This is what it looks like
When the button (white box) is clicked it opens a file selecting box
How can i replace that box with image, i tried placing a image over it with help of wmode transparent but when clicked on image flash doesnt open up the file selection box
How this can be done?
Is there any way i can run the flash when clicked on image because this doesnt looks good.
Little detail as i am more a designer than a coder.
