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?

I have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page.
The script works fine when the requested XML file is stored on the same server as the script.
The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers?
Javascript Code
window.onload = initAll;
var xhr = false;
function initAll() {
document.getElementById("makeTextRequest").onclick = getNewFile;

I am creating an XML document on my page with javascript. My question
is, is it possible to save that xml file on the server (I have write
permissions) only using javascript, ie no server code? This task would
be trivial using server code, but I was wondering if I can do it all
with client code and post backs? Well, any input?
I have the following php script:
<?php
$doc = new DOMDocument();
$doc->load( 'events.xml' );
$events = $doc->getElementsByTagName( "event" );
[Code]....
If an event is taking place now the php script will show a div with information. This chapter is done and working, the trouble comes with the xml load part.
If the load of the xml document is done only once (when the page is first time loaded), I will need to refresh the php script so it looks for more times and info ..but the user will see the page reloading all the time.
I need the php script to look for the events' times in the xml file at all times, so I guess I have to do an auto refreshing of the
$doc->load( 'events.xml' );
how can I do that?
Im writing client-side javascript and I want to do a server side include. There are many server files but only one will be included. These files contain peoples names and phone numbers. This info is packaged as a line of javascript but I can change that packaging if necessary.
The file name to include is being passed as a url parameter: [url]
I know how to parse the url string and stuff the ID number into a javascript variable.
I set <ICODE> foo = "/people/12345.html" </ICODE> and tried <ICODE><!--#include virtual="${foo}" --> </ICODE>
but this did not work.
Is there a way to do this with javascript given that the name of the file I wish to include is contained in a variable? If not, what is the usual way of getting the data in the server file into my client-side javascript?

events.xml contains schedules and info for events.

I 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 got a file upload form (in asp), besides of checking if the extension is .jpg .bmp etc, how do i check if the file really is an image? so pple wont be able to change an exe file to jpg and upload it right away.
View 2 Replies View RelatedIn client side, we can check if some image exists using onerror. I wish the same behavior to check files used in object tag (in client cache, not in file system), like swf, wmv and wma, etc.
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.
I am developing a script to work along side my joomla website and i am wanting to develop a script that connects to my database and refresh's certain divs every 2 seconds without the user noticing this,
only issue is that joomla isnt wanting to work with me on this,
Here is my code,
Code:
<script src="http://code.jquery.com/jquery-latest.js"></script>
$user =& JFactory::getUser();
if($user->username)
[Code]....
since when i do that i get nothing on my navagation where user information is displayed and displays the enter layout in the div right_contenta So can jquery does this.
How can i fix this and get my right_contenta div refreshing every 2 seconds with my joomla layout

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.

I have been searching high and low on how to do this and I think I'm at a loss because I'm so unfamiliar with js and ajax.What I would like to do is have just a single div on a page refresh every 5-10 secs; the content of the div shows what users are logged on; the content is generated by a query on my db
<div id="players"><?php
$online_query = "SELECT user_log.user_id,user_log.ip,user_log.logged_in,user_log.logged_out,users.username,users.type_id FROM user_log LEFT JOIN users ON user_log.user_id=users.id WHERE user_log.logged_in IS NOT NULL AND user_log.logged_out IS NULL ORDER BY users.username";[code]....
almost all of the google results I got for refreshing a div were for updating dropdown boxes or dealt with some kind of page event...so now I'm at a loss on what else to look for..
I am trying to access an XML file from a server in my JavaScript code. I have an XML file like this:

what is the best way to do that, since the returned value is a text.

This might be a combo Javascript / CSS question I'm building a website, and I'm wanting to have small, approx 100px x 100px pop up display that has a "page loading" spinning gif. I also want the page to fade out while this image is displayed. For instance, someone submits a form that takes 3-4 seconds to load. Once they hit submit, the screen darkens, the new window comes into focus, center of screen, and it has some kind of rotating gif, basically a trigger 'on submit'..

I have a website that uses javascript to communicate with the database for the CMS system.
I had a programmer develop a website who refuses to add a logical function to which I am going to have to do myself now.
When you delete an image or file on a page of a website, it does not delete it from the server. It just deletes it from the website and database only and I can see how this will eventually cause problems when files accumilate in the server.
Can someone give me some samples, direction or instructions how I would implement a function so that when the admin deletes the image on a website, it also deletes it from the server itself.
I want a certain JavaScript script to access an XML file on a different server.
I can use PHP or any other language needed if i have to. but the main file must be in JavaScript.
So, I have a dynamic PHP file on my server. I want to make it so browsers can take the code I provide and paste it in an .html, .php, or .asp file, and it'll display across the board.
The file would need to be included, unless someone thinks there's a better way of doing this?
The only example I could think of would be Google Adsense's code? But I'm not sure.
I am uploading text file on html page, that text file lies on desktop and getting updated at every hour. I will keep my html page on server so how will it upload that text file from my desktop ? it is being generated by one cloud sensor .
View 3 Replies View RelatedI am trying to find a way to search to see if there is a specific file located in the current directory on the server. If a folder contains file1.txt or file2.txt and depending on which file is in that folder change a certain javascript variable. What it comes down to is, is there a way to search for specific files on the server and limit that to the current directory/folder.
