Auto-refresh Image Script
Nov 28, 2007
i guess it best i explain what i am trying to do and then what i have done so u can hopefully point out my mistakes.atm i have a webserver setup at home ( local only) and an internal ftp program running on the webserver... i have an ip camera ( mobotix) ftping images every 1 second to the webserver and puting the jpg image in a folder called testpic.what i am trying to do is get a script working so that it auto refreshes the image every second.[code]this basic site puts a copy of the image1.jpg in the middle of the screen and then refresh it every second. but for some reason it displays the first one then when it refreshes the image there is no picture just the box with a cross.. now i know that the image has updated in the testpic file cus i can F5 the page to display the new image that the script should have loaded.

What I am trying to do: A full screen background image, that auto refreshes every 3 seconds.
How I am doing it: I am using EvoCam for my camera software. It uploads the image to my server every 3 seconds, perfectly fine. I am using "Back Stretch" for my full screen capabilities, as I found it to work best is all browsers. BackStretch
My Problem: Using backstretch, applies the background image to the page through javascript, so I dont have an <img> tag to manipulate. A lot/all of the image refresh scripts I have found, use examples where there is an <img> tag. I had used another jQuery method of doing the background that had image tags but did not work in all browsers. When I was using this method, I ran into cache problems where the new image would not load.
Where do I go? I am feeling a bit lost, being relatively new to Javascript, I am unsure of how to go about clearing these problems I have. I feel that the eventual answer is to timestamp the photos, and include the timestamp into the image refresh, and somehow make it so that I am refreshing the
Code:
<pre><code><script type="text/javascript">
$.backstretch("images/myCam.gif", {speed: 1});
</script>
</code></pre>
that controls my background image. I have found scripts that include timestamp refreshes, but the way that EvoCam timestamps the image is of a different format than the way Javascript uses
EvoCam images look like: webcam2011-05-11-16-21-34.jpg
and I thought Javascript looks relatively the same, but without the dashes.
I have a test page set up, where you can see my surly, discouraged face [URL].

I have a form with a list box. Beside the list box I have a link that opens a new window in order for users to enter new records which then appear in the list box. How do I make the list box refresh to show newly added records? Can I refresh it when it receives the focus or are there better ways to do it? Also, how do I make the new window open to a certain size or to make it maximized?

I'm using a combination of Yahoo Pipes and rssdisplayer.js [url] to display some snippets from several RSS feeds on a new site I'm building.
The trouble I'm having is that (i) the feeds don't update when I refresh the page, I think because a cached version of the page is being loaded, and (ii) I'd like to have the div containing the feeds auto-refresh at a given time interval.
I've got a Twitter javascript working that does both these things, but can't work out how to get the rssdisplayer.js working this way.
The rssdisplayer code is:

I wish to implement the simplest mechanism of authentication. There are two input fields, userand password. When clicking the sendbutton, the verify()function is invoked, which checks whetherthe usernameand passwordare both "admin", if it holdsthen it displays the isCorrectdiv, and the isWrongotherwise.
test.html
<html><head>
<link rel="stylesheet" type="text/css" href="test.css"/>
<script src="jquery-1.7.js"></script>
<script src="test.js"></script>
</head><body><form class="header">
Username: <input type="textbox" tabindex="1" id="username"/>
Password: <input type="password" tabindex="2" id="password"/>
<input type="submit" value="Send" tabindex="3" id="send" onclick="verify()"/>
</form><div id="isCorrect">correct!</div>
<div id="isWrong">wrong!</div>
</body></html>
test.css
#isCorrect { display: none; }
#isWrong { display: none; }
test.js
function verify() {
var username = $("#username").val();
var password = $("#password").val();
if (username == "admin" && password == "admin")
$("#isCorrect").toggle();
else
$("#isWrong").toggle();
}

Most of the Javascript I see has some sort of time limit on page reload and is not really what I am trying to accomplish:
<meta http-equiv="Refresh"
content="10; URL=http://coffeeandtealtd.com/buynow.html" />
I am trying to make our buy page reload after clicking the Paypal "continue shopping" button in Paypal Website Standards. The pop up Paypal shopping cart window closes after clicking the button but our buy page doesn't reload. It doesn't reload in Safari although it seems to be fine in FF and IE. how to make the page reload in this specific instance only.

I'm attaching my php test file but this is a JS problem. When I scroll down in the web page and the meta refresh hits, in Windows Safari and IE6/7/8 browsers, the web page re-positions back to the top. In Opera and FF the page refreshes but it stays where it is. Can someone look at my test script and see why it is not working in IE and Win Safari? My goal is to have the web page not re-position to the top on the auto refresh.

I have been trying to figure out how to go about making a table of comments auto-refresh when someone inserts from a comment form without refreshing the whole page.I've tried looking into AJAX for this, but everything I have looked at, in terms of tutorials, just flies right over my head, and I can't really make much sense of it.

I need to make a website that will be used as a traffic light system. So i will have a page with loads of divs starting red, that will change to green when clicked once, and back to red if clicked again, so on, so on. These changes will need to be viewable live on another computer, so changes need to save and will also need to automatically refresh without distrubing the rest of the page.

I am attempting to create a profile page with PHP utilizing AJAX technologies as well. I need profile data to auto-refresh on the page when a change is made in the database but every 15-30 seconds intervals are fine too. I would really like to use AJAX/PHP for this because I think it will be good for me to know and learn.
I have checked the internet for this and all of the examples show a form select/combobox where you select a "User" and then it populates the information automatically in a div below.
But... I need AJAX or PHP to READ THE VARIABLE FROM THE URL instead of a form(Combobox) and ultimately refresh the data on the page with the results from the DB query in the php file.

I'm using AJAX to auto-refresh a chatroom. You can see it on the right of the following site: http:[url]...
The problem is, when large images are placed in the chatroom via BBCode, (temporarily disabled) when the chatroom refreshes, they flicker! This is caused by the AJAX reloading the content, which in turn reloads the image.Is there a workaround for this? I want to allow images in the chatroom, but I don't want to turn off the auto-refresh. Below is the code I am running to refresh the chatroom:
Javascript Code:
Original
- Javascript Code
function update()
{[code]....
Basically, what it does is reloads chatQuery.php and currentlyOnlineQuery.php every 5 seconds, or when a chat message is submitted.

OK this is a concept at the moment.
the thinking goes like this:
1) read the page for last date (somewhere on the page) that the page was generated.
2) compare with current date
3) if it looks old refresh or re-load.
4) check for history to count the number of re-loads, stop at once.
Maybe the refresh/load will not add to history if the page is the same URL
SO: without using cookies - the remote system may not save them - our local library system has the OS instances screwed down to the point of frustration, hence the use of FF portable right now.
But my audience use whatever they use so I want a rouse to work regardless. The last time I checked the library system cache was more than 4 days old for sure. And some surfers have the pages from the local cache by default.
manual refresh usually sorts this and I do have a manual button on my homepage.

Im fairly new to JQuery and need some help. Googling failed me :o have a web page that initially auto refreshes every 30 secs and has a bunch of checkboxes that are initially unchecked. I am trying to make it so that if at least one of those boxes it checked the page stops auto refreshing (without reloading the page, preferably). Is this at all possible? I am using Perl to generate the html.
My auto refresh is in the header, but im open to sticking it somewhere else, as long as it doesnt create crazy memory consumption that i've read about on these forums:<head
