Preloading .js Files
Jun 5, 2001Is it possible to preload .js files the same way as pics (or any other way) ? The reason i ask is I have grabbed some nifty navigation code, but takes a little time to load first time.

View 1 Replies View RelatedXMLHttpRequest Script - Works For Local XML Files But Not For External XML Files?
Oct 2, 2010I 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?

View 1 Replies View RelatedPreloading Images In IE9?
Apr 14, 2011I'm finding IE9 handles the preloading of images using the Image object differently to its earlier versions.For example:
This code in the <head>
Code:
<script type="text/javascript">
var picData = ['num1.jpg','num2.jpg','num2.jpg','num2.jpg'];
picO = new Array();
[code]....
Earlier versions of IE seem to work as FF4 does.It appears that the window.onload event in IE9 does not take into account if all the images have completed downloading via the above FOR loop whereas FF4 and the others do.
The workaround I am using is to preload the images in hidden <img>'s at the top of the <body> and then loading them into an Image object to get the jpg's actual width and height. This is working in IE9, FF4 and the other majors.

View 3 Replies View RelatedPreloading Images - IE 5 Bug
Apr 30, 2001I'm using ie 5 and I was preloading these images for a rollover and I noticed the preloading wasn't working.
I looked at my code from all angles and couldn't figure it out - checked online examples on how to do it - same way I'm doing it.
Checked a different browser - worked fine.
So is there a security setting in IE that may disable preloading stuff? Or idoes my browser just need to be reinstalled?
Image Preloading
Oct 19, 2005I´m using the following code to preload the hover images of my navigation:
Code:
menu_0101 = new Image();
menu_0101.src = "images/menu_0101_h.gif";
My question: When I enter the page the second time will the images be taken from the browser´s cache or from the server?
Preloading Images In IE9 ?
Apr 14, 2011I'm finding IE9 handles the preloading of images differently to IE8 and FF4 and the latest versions of other browsers.
In IE9 the preloading still works ok unless I want to use the width or height properties of the created Image object before the src of the new Image has been assigned to an <img>
For example:
This code in the <head>
Code:
outputs '0 0' in IE9 and '150 250' in FF4 and the latest versions of the major browsers. 150 and 250 are the actual width and height of mypic1.jpg
Earlier versions of IE seem to work as FF4 does.
It appears that the window.onload event in IE9 does not take into account if all the images have completed downloading via the above FOR loop whereas FF4 and the others do.
The workaround I am using is to preload the images in hidden <img>'s at the top of the <body> and then loading them into an Image object to get the jpg's actual width and height. This is working in IE9, FF4 and the other majors.
Have I missed or misunderstood something in the the way IE9 works?
Preloading The Images One-by-one?
Aug 9, 2011I am attempting to preload an array of images on my website so that they preload in order and only preload one at a time (the images are large and I want them to load in the order they will be viewed in.)So far I have this:
Code:
var images = new Array();
images[0]="website/users/user1/images/0001_000_808460.jpg"
images[1]="website/users/user1/images/0001_001_800872.jpg"
[code]....
This preloads the images all at once. I have yet to figure out a way so that "images[0]" loads first and completely before "images[1]" (and so on).
Question About Preloading Images
Jul 23, 2005Is this the correct way to preload an image...?

Button1.src=Image1.src
....Or am I just telling Button1 to use the same source path as Image1?

Preloading Images From Webcam?
May 16, 2009I'm working on an embedded system that I want to stream images from a webcam and having a world of problems.I originally started out using mime's multipart/x-mixed-replace to send the images to the browser and it worked well but IE has no support for it and it simply didnt work on slow connections.So i've changed to creating an image object and preloading it with JS but I cant get any onload functionality to work :crying: I want the page to preload a picture, display it, repeat with the next picture etc.
This is a rough version of what I have so far and it works while the timer is quite high >1sec, but just below that random images don't get displayed. With small delays, say 0.1sec the images are loaded but never displayed. why can't i get it to SHOW the image, THEN load the next one
PHP Code:
<script>
var image = new Image();
var tmr = -1;

Preloading Images For Gallery?
Jul 6, 2011I am developing a website for my budding photographer son, Tom, and I want to provide an gallery where the user clicks on a thumbnail and this displays a larger image. The only way I see that I can do this is to have a link on the thumbnail to load the page again passing the image name or id to the page using a query string and processing this using PHP. If I preload all of the larger images when the site first loads will these images be available in the cache for other pages.Another way is to hover the thumbnails and display the larger image but I need to find a way to keep the image displayed until the user hovers over another thumbnail.

Preloading With Relative Paths
Dec 11, 2005The two pages for preloading below seemed to preload images IF I used an absolute path but they don't preload the images if I just used relative paths like the ones below.
Give it a try. The two pages below using relative paths won't work. Then try changing the paths of the images in both pages to use absolute path(with http://) which will work.
But I want to use relative paths. What can be done? Other than inserting 1x1 size of the images I want to preload. Code:

I tried doing the following but the images don't pre loaded. They appear one after another.

Preloading Over 300 Images Not Working?
Feb 16, 2010I am trying to preload over 300 small images. I am using a local developement server at this point and testing in IE. As the user interacts with the page many different images will be appear and dissapper for them. It needs to be smooth. I was noticing that the status bar at the bottom of IE keeps saying the images are being loaded. So I thought I would try preloading the images. After implementing the following code, the IE status bar seems to still show that the images are loading each time and I havent noticed any improvement in load times. Could it be that the images are not really being preloaded? Here is the code I am using to preload (it is triggered by onload in the body tag:
imageObj = new Image(width, height);
imageObj.src = "images/pp1234.png"
my actual code repeats the second line many times in a loop with different image names, but this is the most basic for of my code and it results in the same problem. Are there known issues with IE and preloading?
Preloading Images And External JS File
Oct 15, 2005I've inherited responsibility for our church's website. It has a
sizeable main menu, which uses mouseover image swaps. These images use a
pre-load script but the script is only included in the index.html page. My
javascript knowledge is weak, but it seems to me if a viewer arrives first
at page12.html, he gets no benefit of the preload script. My quandry -
Should I include the preload script on every page, or would this force each
of these images to download again everytime a viewer moves to a different
web page, thereby gumming up the whole works? If I don't add it to every
page, the viewer who enters thru a backdoor has a sluggish menu, right?
If the right approach is to include it on every page, can I do this with an
external js file? Will I need to call this file, or will it work just by
including the js statement in the <head> section:
<SCRIPT LANGUAGE="JavaScript" SRC="preloadscript.js"></SCRIPT>
