I'm try to set up a webpge that will play a live flash video on the left-hand side(got that part working) and display one slide of a presentation(jpg) to the right of the video. I would like to be able to control when the slide image changes by having some js check a text file on my server. The text file could contain something as simple as "Slide1.jpg". I will manipulate the text file with some code I've already written. Is there some simple js code I can put in my page that will cause it to check the text file every 5 seconds, and if the content of the file has changed, to refresh the image on the page with the new image? I'm try to get away from the "clicking" sound that is caused by doing a simple refresh of an Iframe.
View 3 Replies View RelatedI have a site with a news pages and I'd like the navigation to include a
blinking 'NEW!' when that page has been updated within the last three days.
It works fine for the one page (if you're on the news page, it works great)
but I can't figure out how to check the time/date stamp on a file other
than the one currently loaded ...
So I'm trying to create a custom file uploader which will display the name of the file selected, but since I can't seem to figure out how to do this I've settled for checking to see if a file has been selected, but I'm still having trouble with it.Here's what I have...
<style>
#upload {
display: inline-block;
text-align: center;
[code]....
However the value doesn't change after the file has been selected. Could someone tell me a means of modifying this so that it will properly display once the file has been uploaded? Do I need to have some sort of constant refresh on the Javascript to check to see if the value has been changed?
I have seen many Javascripts on Internet that checks the extension of the file before uploading. But all these scripts checks the extension when the Submit button is pressed. I want to check the file extension as soon as the file is selected. The script should delete the selected file from the type=file box and display an error message (when a file with the wrong extension is selected).

View 1 Replies View RelatedI was looking in the firebug debugger and noticed that my main .js file was somehow being called twice, but I don't see where. There are dozens of files involved in this particular problem, so I think the best way to go about solving it is to test - in run time - if my js file is already in place on the page, do nothing - otherwise call it. This is pseudo that I have monkeying around with but it's not working.
Code:
function checkFile() {
var fileExist = new fileExist();
fileExist.onLoad = isPresent;
[code]....
I thought this would work, perhaps it's because of an argument I need to pass in to checkFile(ZYX) but not sure.
Is there a way using javascript to have it check if a file exists on the server? I'm trying to check for a file on my server without having to refresh the open webpage. If this can't be done with javascript, do you know which webpage languange can execute this?

an image every second. Is there any way of programmatically checking to

I'm creating a script to get the next photo without reloading a webpage. To make it more smoothly, I fadeOut() the old image, and fadeIn() the new image.
However, when the new image is not yet fully loaded, the fadeIn() method doesn't really make sence. So I wonder if there is a way to first show an ajax loader, and after the new image is fully loaded, fadeIn the new image.
This is how far I got so far :-)
I first have to remove the first img tag, and inject a new one in the DOM, otherwise the old image flashes for a second, before the new one appears ;-)

Is there any method in javascript for binary conversion.. convert image file to binary file.
capturing just the file name rather than the entire path of the SRC on my input type="image". Basically when I hover over an image, the Default Image should change to the image being hovered on. Here is my code, can't quite get it to work. Sorry I'm very new to JavaScript
<html>
<head>
<script language = "Javascript">
function ChangeDefault(src)
{
//document.frmMain.DefaultImage.src = src <--Doesn't work at all
alert(src) //<---Displays the entire file path, want just file name

I'm using a script to include images into a slide show using direct URLs to the image files, but I am using fckeditor (PHP) for my users to edit their content. The script in the .js file that pulls the images into the slide show.The user's image file is going to be named something like, "userImage01.php". Inside that file would be their image location path ~ "images/user/image1.jpg".Therefore, I need the above javascript to pull-in "userImage01.php" INSTEAD OF the image's location path.

View 3 Replies View RelatedI have almost 300 photos that I want to have in a gallery that is easy to use. I would like to avoid making 300 list items (as is necessary with all of the auto rotators and other jquery plug ins that I've found) but to have the images load straight from the folder after the rest of the website has loaded.
It wold be nice if maybe there was a pretty horizontal scroll bar or something and the image in the middle of the page was biggest if possible, but I'm really not picky. I don't know what the best way is to display so many photos! They don't need captions or anything.
Is there any way to add "alt" attributes to the images in the .js file?

I'm trying to get the full value from an "image" field, with this:
$('#client_local_offer_image').change(function(){
alert($('#client_local_offer_image').val());
});
However, the value only seems to include the filename - and not the full path (what I'm trying to achieve, is a "preview" feature - which will shrink the image down to a fixed size, and update an existing <img id="xxx"> bit in the HTML)
I have a JS which I have already started to try to customise, but I am having some difficulty with it in that when I click on an image, it does not take me to my html page.with care.html. Although all files are in the same folder, I get an error indicating that the fille cannot be found (I have checked the file name spelling). I am not doing any of this online as the Web pages, when working, will be put on CDs.
View 7 Replies View RelatedHey everyone, I'm working on a website, and I have one page that uses a forum that is supplied by tal.ki.The forum works fine, but the .js file that the forum uses is grabbing the image that I am using as my header on the page (not in the header of the html, just on top of the page) and moves it down and right from where it is supposed to be. My apologizes for the file being so long, but I have no idea which line it is that makes the image move. If needed, I have pictures of how it looks in the program that I use, vs. how it looks when viewed in a browser.

Is it possible for 'Random Image Script' http://www.javascriptkit.com/script/cut144.shtml to be a js include file rather than having to be in the body tag so that I can edit it centrally and apply to multiple pages rather than having to edit each page individually when I have a new image and link to add to the script?
