Port Listen/send
Sep 16, 2005Is JavaScript able to send/listen for data on a specific port? I'm seeking
a solution to real time data interaction with my web server that doesn't
require refreshing the page. I.e., a chat room, where the data can be
broadcast from the server arbitrarily and displayed by the client
browser(s). To accomplish the data transmission can I use JS, or do I need
to augment my client-side platform to something like Java, et al?
Javascript Port Watching
Nov 7, 2005Basically, I want to have a javascript that will watch for data coming

possible with pure javascript?
Connect To Tcp Port Using Script?
Aug 17, 2009I'm a newbie to javascript programming and I'm seeking on a solution on how to connect to a tcp port using javascript. Basically, we have phone server that is constantly streaming XML data on port 1024 (serverIP:1024). I've ran a packet sniffer and was able to gather the elements and attributes for the XML data that the server is streaming. Now, I have a test XML parser which works with the XML document using the elements and attributes i've gathered from the packet sniffer. Is there a way for me to connect to the TCP port i've mentioned using javascript and incorporate it with the XML parser that I have. code...

Port Of PHP's Date() Function To Javascript
Dec 7, 2002Okay, this an attempt to port PHP's date() function as much as possible to JavaScript. Could use some refactoring though. Any critique, comments, appraisal and any other opinion is very welcome. Feel free to discuss and also take a look at beetles code here: http://www.codingforums.com/showthread.php?s=&threadid=11069

JQuery :: AJAX Calls To A Server On A Different Port?
Nov 3, 2010I know about the same-origin policy and that one of the only ways to load data from a cross-domain is to load it as JSON. However, all I am trying to do is access data from a server on another port (which I believe the browser still treats as cross-domain). I need to do this because the server my application is on is a map server and the other server (Apache) is the only one that can handle php scripts. I have also tried out the plug-in from [URL] and while it works when I do $('#phpContent').load('http://www.google.com'); it doesn't work when I try $('#phpContent').load('http://localhost:80/mapScripts/getFiles.php'); I have also tried$.get('http://localhost:80/mapScripts/getFiles.php', function(data) { $('#phpContent').html(data); });
So here I am breaking my brain and do not know what else to attempt.

Any Way To Parse Sounds From Mic?
Aug 1, 2011I know javascript can't do this natively but with flash or java it should be possible right? I'm thinking of doing something along the lines of a tuner ( [URL] , but a bit different). Any framework for reading notes from the mic with javascript? Preferably something which takes care of all the flash/java integration.
View 1 Replies View RelatedJQuery :: IE7/8 While Trying To Parse XML In An IFRAME
Dec 20, 2010I am using the infamous hidden IFRAME trick to manage some image uploading. My server-side ASP page passes back XML to indicate success or failure. It was a snap to grab this in FireFox and parse it using the standard JQuery methods. Then I spent most of an afternoon trying to do the same in IE, I finally found this page and this comment: [url]
JavaScript, IE, XML, IE uses MSXML and an XSL stylesheet to transform the XML to some HTML document that pretty-prints the structure of the XML. That way when you access the iframe document you indeed access an HTML document that IE renders. However IE stores the original XML document in an XMLDocument property of the HTML document object so to access the XML data (and not the HTML document) you can do e.g. var xmlDoc = window.frames.frameName.document.XMLDocument; [...]
The solution thus ended up as follows:
From there I can use all of the normal JQuery code to traverse the XML. Anyway I am not sure if this is an IE bug, a JQuery bug and/or presumably specific to this wacky IFRAME scenario versus a normal document.
JQuery :: Parse Xml With Name Spaces?
Feb 27, 2011I am trying to get two values from a web service response.
The web service was called using jquery $ajax:
$.ajax({
url : "http://localhost:3032/ufs/integration/copymoveTerm",
type : "POST",
dataType : "xml",
[Code]....
All I want to do is to get the values of UNDO_COUNT and MSG into separate variables.
Here is the jquery I am trying to use:
function undoSuccess(xmlData, status, xmlResponse)
{
$(xmlResponse).find('res:OUTPUT').each(function () {
var undoCount = $(this).attr('res:UNDO_COUNT).text();
var msg = $(this).attr('res:MSG).text();
});
}
I have tried it with and without the name space "res:". I have tried it with xmlData and with xmlResponse I have tried changing the web service so that UNDO_COUNT and MSG were elements in their own right or were attributes of OUTPUT all without success it just bypasses the initial find on OUTPUT.

Parse Xml Using JS Into Html Table?
May 3, 2011New to this, worked through the w3c tutorials and am really fascinated by some of the concepts. I'm only familiar with html, css, js (basics), so am trying to keep things as simple as I can for this.
For simplicity I'll use books.xml with a listing of books. Each book has a <title><author><year><price> and <image> element. The images are stored in a folder called "images" a path is listed in the xml document.
Using js and an array I can loop through the xml file and have it extract each node into a table, if I mouseOver a ROW in the table, it displays that listing in a DIV above and I would like it to display the image/thumbnail for that particular listing within another div called thumbnail which is in the same location regardless of which listing you mouseOver.
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
[Code]....
So the way this looks is there's a grey div. At the top it says listing, and when the body loads it lists the [0] first entry from the array. To the right of this is a small div called thumbnail that is empty and I would like it to load the relevant image from the path in the <image> tag in the xml file.
Below the listing is a table with 4 columns (title, genre, price, image) and an equal number of rows to the number of listings in the xml file. Under the "image" column it just shows the path to the image.
So how do I tie the empty thumbnail div to the listing so it'll just add the path from the xml <image> tag into a <img src="pathnamefromxmldocument">
HTML String Does Not Parse
Jun 6, 2005I have a HTML string (which I retrieve from an XML file) and when I display it with

Parse Error Using Jsonlib?
Jun 5, 2011I'm playing a bit with the goo.gl API and Javascript using the jsonlib like this:

header: 'Content-Type: application/json',
[Code]....
PS: I've removed my API Key from the code to make it public, on my test the API Key is there and it is correct, since I can see the valid JSON if I click on the fetch:1 on the Safari Debugger
Parse HMTL Before Output
Apr 5, 2010I have a variable which contains a string of html that I wish to output into a content div on the click of a button.I can toggle the content of the div with the string above, but I wish to include the ability to parse that string before output, so I can translate its language before its output.I can easily do this once the html is output into the content div using the JS HTML DOM, but due to this conversion not being instant I'm looking into ways of translating this text before it is output, so changing the string stored in the variable html.
