I'm a newbie trying to modify the code in an AJAX tutorial to load data from an XML file, and it is not working. The code is in a php file that is invoked with the URL:getXMLTest.php?showName=photoShowTest.xml The code I've written (mostly copied from the tutorial, actually) is:
<!Doctype HTML>
<html>
<head>
[code]....
I'm working with a pretty large XML file, but I really only need to
display a few things that requires quite a few transforms. I already
limited to the transforms to the data i need to use, but I'd like to
speed things up by loading only the data I need.
I need to mention that this is for a local application that sometimes
will lookup updates on a server, but mostly, it is for local use
(offline)
I can use xmlHTTPrequest for both local or server data access. That
seems to work fine. Now I would like to be able to load only the data
I need.
I hear the Google suggest tool bar uses xmlHTTPrequest to look up a
list of known queries, so I am hoping they lookup "only" the necessary
data as one types. It's kinda what I want to do, but I'm not sure how
that would work, since the "url" parameter should be a destination
file name.
i can get my xmlhttprequest onbject to send data using GET and POST....but I would like to use it in a form which has a FILE input...is it possbile to send the file to a server-side script using the xmlhttpreq object?
View 3 Replies View RelatedI heard there is something called XMLHttpRequest that is compatible to all browsers. What does that actually do? Is there something to do with Javascript?
View 2 Replies View RelatedI have a very important question. I am currently attempting to create a Javascript file to test the HTML5 File API. First of all, I want to dynamically obtain a local file using Javascript and Google Chrome. I have succesfully done that by using a function which returns a XMLHttpRequest() object. However, when I try to access the content of it, I get empty space.

Can anyone tell me how to use XMLHTTPRequest or MS ActivcXObject open a
local file?
I am looking for a way to select a file from a list and load it into a webpage. The page and the files are stored on a sd-card for off-line usage, I know that listing files remote dynamicly needs a scripting engine but since the sd-card is on the client side that is not possible, but I can make a list of those files when creating them.
It is intended for a datalogger on a tractor-puller, I create csv files with a bash script on the logger and for off-line viewing I use a javascript charting engine which loads the csv file, the files have the creation date as filename and I can make (and maintain) a list of files when creating them. The plan is that the we can select another data set (run) from within the browser and show that one. I have setup an example at [URL]
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 use the following to load an xml file...
xmlDoc=document.implementation.createDocument("","",null);
xmlDoc.load("file.xml");
xmlDoc.onload=getmessage;
How do I check if it had loaded correctly? I read something about a ready state you can call?
What's the simplest way to fetch a js file from the current website, then
cache it?
I'm using dojo, which has a large js file when using the built version.
As a mercy for dialup users, I want to serve up a tiny 'loader' html page
(containing an animated 'loading...' gif) which, when loaded:
1. retrieves the big js file, and plants it in the cache
2. when the js file is retrieved, then sets document.location to
the url of the real website page which uses this js file, and
thus redirects to that page.
i need jquery to load for 3 tables from different php files without leaving the page , and table links on the bottom . So , onclick , links will load those external php files without leaving the page . Here;s a example of what i need :D

What I mean by this is how do you load an xml document that has been inputted as a string in a form. I would've assumed it was something like this, but this doesn't seem to be working.
<html>
<head>
<script type="text/javascript">
function loadXML(file) {

i was wondering if it is possible to load text into a string from an
external text file. the reason is that i have a very large string and
it is making my script very messy.
also, is it possible to have some dynamic parts of the text from the
text file? for example, if i load in a string and there is a part of
it that inserts a value from a variable like the following:
'The number of people is ' + var_people_num;
....so the text from the external file would load but these parts would
be given the value of a variable contained in the script that calls
the external file. its not absolutely crucial that i obtain this but
it would help me seperate large chunks that complicate the script.
As we all know, JavaScript is client side and php is server side, (the php
code is 'allowed' to do stuff on the server that JavaScript cannot).
The problem with php is that it timeout after a while, (and the user also
has no clue as to what is going on for a long time).
I need to run a script on the server that could take a very long time.
So what I was thinking is mixing both JavaScript and PHP
Something like,
<script>
var endvalue = 1000; /* some number that the server can calculate
quickly */
var i = 0
while (i<=endvalue)
{
/**
call a php file that will do some work
somefunction.php?someNumber=i
*/
}
</script>
That way the server does the work, while the client keeps it going.
Ideally I would also get a return value/string from the php script.
I have a JS file on site A which needs a few parameters from a short text file on site B. Since crossing domain boundaries in JS is problematic, the way I do it is that the JS actually opens an intermediate PHP file on site A which redirects to the destination page in site B. Here's how it goes:

The problem is that this takes a long time. I would really like to speed this up. For example - I thought of using a direct IP address, so that there won't be any need a DNS server (using
Code...
) but this would expose me to hackers as it would make my Hostgator username visible. According to HG support the above format is the only way to access my subsite via direct IP.
Any ideas on how to speed this up, either by bypassing DNS (but without exposing username) or by offering another way of reading data across sites?
I'm building a home page with an update checker. A function, called 500 millisecs after the page loads, appends an external .js file and compares a variable on it to a different internal variable. If the internal variable is lower than the external variable, then the update prompt is displayed.
This all works fine, but the status bar says "Read www.primedesigning.com" (the site with the external js), or sometimes "Transferring from www.primedesigning.com". But, if I hover over any link, the status bar goes back to "Done". Also, if I leave my mouse still, wait for the update prompt to appear, and then move the mouse, the status bar says "Done".
I have the Fasterfox extension installed, and it confirms what the status bar is saying. It never stops loading unless I do 1 of the 2 solutions mentioned above.code...
I want to put some additional checks while loading the file for that I need to check where each line contain the "|" symbol or not which I am using as a file delimeter.Can anyone tell how can we read the file line by line in javascript.

I have some code that performs differently in Opera than it does in any other browser. So I have a stylesheet specifically for opera. Is there a way to do something like this, where I check the browser, and if it's not opera, then load the default sheet, otherwise load the opera-specific css?

As of this writing, that code seems to break my page, as if it doesn't like loading a sheet based on an if/else clause.
i found a way to click a link and load it into a div. the only problem is that i keep getting the "AHA error" from the if statement in my div.
i'm not sure if it is me or the coding but i'll post what i'm using in jscript here:
function ahah(url, target) {
document.getElementById(target).innerHTML = ' Fetching data...';

i don't think it's because i'm using an image map (i know... ol' skoolin it)
I'm currently working on a site and need to have a small section that displays 5 or 6 headlines. The same headlines will displayed on various pages and will occassionally be updated.
The site pages are static .html in design and i'd prefer to keep it that way rather than start introducing php for such a minor part of the site.
I am wondering if there is a javascript solution to this, whereby the headlines could be loaded via a .txt / .xml document or something similar?? That way i could just manually update the file and reload it to the server and the headlines would be updated.
I guess i'm think something similar to cushyCMS but that i can implement directly.

A program I am writing will be loading the data of a file into an array. This data is read as an image and is displayed. Part of it will be the modification of palettes, so if I click Palette 4, it would go in and edit the array to have new contents (predefined by me) and redisplay the image in place of the one that was there before. How would I load a file into an array and display it as an image and stuff?
