PHP Code:
I can't get the "ola" to show on the page when I do a refresh.
I'm getting "bar undefined".
I do have a lot of simple and quick questions, but I will make just one:
Why am I getting "bar undefined" ?
I have a link (#botaoMovimentos) and, by pressing, it returns data from mysql.The sql query is ok. I've tested. But i keep getting this error (ui is undefined).
What is missing in here?
I have the index.php file with this code;
in ajaxMovimentos.php i have:
in usuarios.class.php i have:
I need to fix the communication between the JS located in this page and the PHP form script. When the form is submitted I want the page to automatically update which is already present in the script, thanking the user for the submission. Since the PHP script was changed that communication is broken and I hope to get it communicating once again.

An example of this is isketch.net Also on this site i would like users to be able to create accounts and join 'rooms' where they can communicate in real time (as opposed a forum message board). I am looking for something similar to isketch.net
Could somebody please tell me the type of development and programming needed. I have been quoted 1000 a month to build these capabilities but have no idea what is involved. (also may require facebook style real-time updating)
How to do serial port communication using Javascript?
View 2 Replies View RelatedI am new to Javascript and am trying out window communication with a popup.In the main window it opens up a popup window with a button click. The popup window is trying to grab text from the main window and put it in it's (the popup's) window. I guess it needs a test to see if the window is ready??Here's the code:

I'm trying to find a way to have a script communicate with a server
without having to load a new page. The idea is to have the server act
as a simple wrapper for a database, letting the client do that icky UI
stuff.
I tried the obvious, putting a frame somewhere it doesn't insult the
eye, changing its location, then accessing the new content via DOM.
What I get from IE (6) for my pains is just a rude "permission
denied". This even though I entered "localhost" as a trusted site in
IE's security setting. What's amiss?
let'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).
I have a web app with a game and chat updating with ajax very frequently sending thousands of XHR requests to the server during a user's session. The problem is that most clients experience intermittent connection failures or timeouts. On the server it appears to be fine, all requests are logged to have completed successfully and on time but the client gets either a communication failure or a timeout. This makes the user feel like the game or chat just got stuck.
I use YUI for making the XHR calls but I replaced that with jQuery with exact same results. I make sure that only one query is active at a time, so I am sure that I am not hitting the max 2 connections problem. The failure rate may be 1 in 200 hundred requests or something but it seems that when a client has a failure then it fails at a higher rate, say 1 in 10 until the problem goes away. I have clients send back an error request when such errors happen in order to track the problem. I have tried various things to try to figure out what is wrong but I have not found anything. I don't think that it's the client's connection as it happens to a sizable portion of my users, it doesn't look like it's the server either.
So what I am wondering is whether this failure rate is common or expected when doing heavy ajax staff and I need to find a way to work around it or this must be a problem in my system that I need to figure out. If the latter any pointers where to look at?
I have set of frames... one contains a menu and the other a status frame. I am calling a function from the menu which sets the variables however I need some help passing those variables to the status frame. How would I go about doing such a thing?
This is called from the menu in frame 1 but doesn't work:
Code:
function jumpsec(cat, prod) {
parent.statusbar.category=cat;
parent.statusbar.product=prod;
}
// then my status frame bar has:
document.write(parent.statusbar.category);
document.write(parent.statusbar.product);
The 2 variables are blank on statusbar onload but get populated with each click.

Is-it possible to modify a window from an another window without having a
link Parent To Child?
I have need to communicate between two iframes of the same domain, which live inside a parent page on a different domain that I have no control over. This is a Facebook app and the basic layout is this
apps.facebook.com/myapp
L iframe1 (src='mysite.com/foo')
L iframe2 (src='mysite.com/bar')
I need frame1 to talk to frame2, but in Opera I can't access window.parent. frames['frame2'] to do the usual cross-domain methods (updating location.hash for example) Is there an alternate way to accomplish this in Opera?
I am working on a robot project, that is required to create a website to control the robot via serial port.. The website is plainly html, no linking to database is needed...

I have a JSON structure in API.When I call the API in my code it returns as the same JSON .I have to print this JSON result as table with pagination in Javascript.

start code:
The problem is that .css treats snip[1] as a string but I need it to handle it as a json array.
Bad: .css
Good: .css
I have a html file that I want to load, loop through the json data and for each json entry I want to add a new block of the html and insert the json data into the matching div/class of the html. json looks like this:
{"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
html looks like this:
<div class="Name"></div><div class="Age"></div>
So for each json entry of name/age, I want to insert that into the html, and then add another row, until all json data has been fetched. After this I want to insert all of this into #box, which is just a divthat should contain that html. Looping like this obviously does not work, since I just keep replacing the same html through the loop.
var jsonData = {"Super" : [{"Name" : "John Doe", "Age" : "30"}, {"Name" : "Jane Doe", "Age" : "40"}]};
$.each(json.Super, function() {
$('#box .Name').html(this.Name);
$('#box .Age).html(this.Age);
});
This is using Microsoft Windows with IE. I have a form with a text box which I inspect onKeyDown to determine what key is pressed. Also if the page sits idle for a while an alert box comes up. Here's my issue.
If I load the page and wait for the time out a message is written to the staus bar. That works fine. But if I load the page, type one character in the text box and stop all activity the page times out again. But this time after the alert box has fully formed, the status bar quickly receives the message I want there but instantaneously changes to undefined.
in javascript, is there a way to test if an array is undefined????
eg...
for (var x=0; x<10; x++){
if test_array[x] is undefined then x++
document.write(test_array[x])
Looking for clarification of undefined variables vs. error in
JavaScript code.
e.g.
<script>
alert( z ); // this will be an error, i.e. an exception
</script>
<script>
alert( this.z );
alert( window.z ); // both equivalent, no error, but window.z is
'undefined'
</script>
why is it that 'z' alone without the global object generates an error,
shouldn't it also be undefined? for example if i did
z = 0;
the javascript interpreter knows to create a global variable z
Has anyone came across a situation or know how the
document.fileCreatedDate property could be throw a JScript Error in
IE6 browsers?
I am using this in a function to help determine an IE browser (with
other properties). It has been reported to me to fail in others
browser. Since it works on other peoples machines I would make me
think is there something that can be done to a webpage that can have
this cause an issue.
ns 7.1 on win2k:
i am trying to sniff out the (ax) version of the NS browsers and am
not having any luck. both of the following alert 'undefined':
alert('GeckoActiveXObject=' + typeof GeckoActiveXObject);
alert('GeckoActiveXObject=' + window.GeckoActiveXObject);
it seems very straight forward but the results are puzzling. has
anyone had this same issue? thoughts/suggestions?
