Does anybody know how to use javascript to test whether or not an
internet connection exists? Is this possible even?
I have a script which needs to detect when the internet connection is lost and hold the content of the web page until the connection is restored.
I have been given a head start with a small javascript which I am trying to get to work.
My web page, I have a web page which contains some text and graphics but more importantly it also has an iFrame. The iFrame connects to an SQL database and displays data which is refreshed every 20 seconds.
Because the internet connection at the location where the script will be running I get connection loss which makes the iFrame loose its data. The Javascript I am working with is below.
Code:
I would like to be able to know if there is internet connection
Something like this:
If it posibile to do something like this in javascript.
I'm having trouble finding example code to detect the presence of an Internet connection. It doesn't seem to be a very frequently asked question, as all I need is the answer yes or no (is the user connected or not).
I'm not interested in speed detection or any other aspect of the connection, just its existence or not. The reason is to be able to intercept link clicks on a CD-based set of HTML pages and pop up a warning if there is no connection; otherwise pass the request through to the net.
It is possible to run dynamic web pages on a pocket PC without internet connection?I would like to read/write files using a browser on my pocket PC without internet connection.

Is there a way that the web page can be automatically refreshed if the connection is lost using JavaScript. I need to continually refresh until the connection is back on.
I know all about META refresh but that does not help.
I have a javascript code with a countdown timer that runs on the client side and is updated regularly to the date set in mysql db.
I want to make the timer stop when the internet connection is lost. I am thinking on using clearTimeout()...but I need to associate it with the internet connection.
Here is the script:
The problem is, the extension tend to crash when there is no internet connection, and sometimes, the http requests fail to communicate with gmail server, they got built up over time and end up flooding the memory.

I am attempting to create an Access database connection from within an HTML page. I am using Javascript to make the connection and then test a basic UPDATE statement.
The following code is throwing back an error 'UPDATE statment syntax incorrect'

I thought the syntax was correct, but maybe it is something else?
I am working on a registration page.I did all the validation but facing problem during username validation.when a user enter email id in the textbox,it first check whether it is present in database or not.. if not present "register successfully" otherwise "email exists"

I'm using the standard module pattern and the problem is once you set a private variable, trying to test that object independently becomes a nightmare as the next test is polluted by the actions of the previous.So, the options are to have some reset method (which is horrible), setters on everything (defeats the point) or delete object and re-load script (hideous).

my javascript create new element when it is first loaded.
the code work fine in opera and mozilla and netscape, but it failed in
microsoft IE. message:
Internet Explorer cannot open the Internet site
I check the google, found some info. But, none related to my problem.
the cause is due to creating new element while the page is loading.
How to do that without problem?
So this works just fine in FF. In IE7 I am getting this error. I can see my content load in the background, when I hit ok it takes me to a page cannot be displayed page. If I comment out:

My question is, if I download javascript from a server (say Facebook), and then I send out a request to view some photos. The sever sends me back a list of IPs of other servers which have those photos. Now can I set connection to the other servers via the javascript? Or does the javascript can only talk to the original server?

View 3 Replies View RelatedI am trying to figure out a way to have a page redirect if the mysql connection fails. The issue is that the page is already loaded and the only time this would be needed is if the user tries to perform operations on a loaded page after the session runs out.
So basically, I have a page that will allow you to search for an item using ajax, then select an item and press add which will place the item in another table displaying detailed information. Both operations connect to the database using SESSION variables to save the connection information.
My goal is to use the "or die()" method to print something that will force a redirect because this could happen in a number of places in the site and I want to try and get them all in one swipe.
Here is what seemed like it would be the most promising:
$conn = mysql_connect($_SESSION['host'], $_SESSION['username'], $_SESSION['password']) or die("<script>location.href= '../login.php'</script>");
Unfortunately the javascript never runs.... I tried putting alerts also and nothing, but with firebug I can see they are printed.
how I can ensure that the javascript is executed?
In the home page (index.html) i have a flash intro. The first time a user sees the website, the intro should play. Once he goes to another page (about_us or contact_us) and comes back to the home page, it should show a different swf (the version without the intro) - i have created two swf files. I need to know how to change them when the user has already seen the intro or was in the home page before. When i googled, i found something on cookies. I have no clue on how to set them and change the swf file.

Automatic detect default page and check to low band version go to html page or high band version go to flash page.
I was wondering if there's a quick and simple way to notify a user if an ajax connection is broken, for example you're calling a file, but due to your internet connection, the file cannot be relayed back to you, so the existed javascript code on the initial page you're on, notifys you of the problem.

According to HTTP/1.1 specs, a client should only have two connections open
to the host at a time (which can be changed by browser users, of course).
When using xmlHttpRequest connections, is there any way to detect that the
request is queued?
I did some tests (see "Queued Requests" at
http://www.ajaxtoolbox.com/request/examples.php ) and it looks like
readyState 1 is fired immediately after the request is made, even though
it's not actually active yet.
Is there anything else I can look at to tell if my request has been queued
and hasn't actually started running yet?
Is there a script to detect the internet connection speed of the visitor of the website in order to determine if the HTML or the flash content of the site wil be published. This to prevent the visitors to struggle with large flash files en give them the best possible experience. On the other hand to satisfy the need of the fast speed connection owner to get a rich internet experience and to brand my products with trendy content.
