I am having an issue with a script which fails when the internet connection is lost, and so it should.
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 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 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:
I want to have a popup that shows up if the user loses connection to my website, i would prefer it to be in jQuery as that's what I'm using, and it seems more light weight on the page
I have this code, but it doesn't seem to work... it should check on document ready then keep trying every 5 seconds
PHP 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.
Does anybody know how to use javascript to test whether or not an
internet connection exists? Is this possible even?

Is there a resource on the internet to tell me which javascript can
work with which browser.
For instance, can I use style.color with all browsers - that kind of
thing.
I'm not sure if this is possible, but I'm looking for a way to access
another IE browser window using JavaScript (assuming the two browser
windows are running in the same instance).
The purpose of this task is so that if a user hits ctrl+n in IE, the
new window is "aware" of the other instance.
I build a website with Typo3 and it works fine, except for the text size in Internet Explorer (and Opera). I tried anything from changing the CSS templates (excluding them) to changing px to pt to em and so. Finally, I think i need a Javascript that detects the browser and if it is Internet Explorer (or Opera) the textsize should be reduce by 1. It therfore should be the same like manually clicking in IE on View->text size -> smaller (default is medium).
My javascript (I just use Javascript for this single purpose) does not work/it does not do anything:
function resizeText(){ if (browserName=="Microsoft Internet Explorer") {document.body.style.fontSize = parseFloat (document.body.style.fontSize) -1 ;}}

What is the simplest/easiest way to display messages from another
script without refreshing the browser.
I have a server side script that dumps messages like.
server_received.php
<?php
...
echo "received fn123.tar";
...
echo "moved fn123.tar"
...
echo "received fn567.tar";
?>
I can dump the above messages into a file if necessary so
many clients can read it. Want a client like below
client_viewer.php
I want to display the above messages at the bottom of many other
other pages at the bottom as I receive the files.
I have a piece of JavaScript code that uses the location.Reload method to reload a form that has a textbox and radio control. Both are supposed to contain the same random number. When a button is Clicked, the location.Reload method is called and everything updates as expected. However, the BROWSER Refresh button only repopulates the dynamically generated radio button. The text box retains the old value.

When we refresh the page (F5, or icon in browser), it will first
trigger ONUNLOAD event and then trigger
ONLOAD event. When we close the browser (X on right top icon), it will
trigger ONUNLOAD event.
Now when ONUNLOAD event is triggered, there is no way to distinguish
between
refresh the page or close the browser.
Here's the code fragment. The logic in window_unload() only applies to
closing the browser, not refreshing the page.
<BODY ONUNLOAD="window_unload()">
function window_unload()
{//logic that only applies to close the browser, not refresh the page.
}
Anyone knows the workaround to the problem?

I need some script to force the browser to reload/refresh when a page is reached from the back button.
EG You're on page A -> You click a link onto page B -> You Press Browser back to go onto Page A, it has old content that requires a reload.
Now, my page is currently php so I won't bother with my code here as I am looking for any solution (I have also posted in php forum).
Any JS solution that will trigger a reload on browser back is appreciated. I have tried a few ideas, most work in Chrome, IE always works, Firefox 4 and Opera 11 wont reload, simply fetching from cache I believe.

<script type="text/javascript" src="js-bin/silent_refresh.js"></script>
In a javascript named silent_refresh.js: (make sure the script is in a folder called 'js-bin')
window.onload = doLoad;
function doLoad()
{
setTimeout( "refresh()", 60*1000 );
}
function refresh()
{
window.location.reload( false );
}
The page will refresh every 60 seconds - Just alter the 60 to whatever time you require.
I have a large form that uses jquery's .change to rewrite html select forms, make some calculations, etc. It works great if I don't reload the page via a refresh or a back. If I click back or refresh it doesn't change some of my form's selections, but all of the jquery generated stuff doesn't recalculate. Is there a way I can trigger a re-evaluation? I tried
$(document).ready(function () {
...
(#id).trigger('change');
...
});
