Slideshow Timing (basic) - Message Should Disappear After The Final Image Has Been Preloaded
Dec 19, 2010
I'm trying to build a slideshow page in Javascript. It's dynamically built and all of that is working, but the Javascript timing is giving me trouble. First, a PHP script builds an array of Image objects to preloads. I have a 'Loading pictures....' message appear in the foreground of the page. This message should disappear after the final image has been preloaded.
I'm using Javascript's onLoad() event of the last image to change the message's CSS div display property to hidden, but it always executes immediately, even though the browser is obviously still working. Is there a way just to tell Javascript "do not proceed with the rest of the code until this task has finished"?

I have been trying all morning to put a basic slideshow into my site from the below link[URL]... am pretty new to this and having to host my images on Photobucket as I use Big Cartel. I cannot figure out where to put the image links and do they need -
<a href=" " ></a> or just direct links?

I am using a slideshow and want to basically have an 'image loading' whilst all the images load before the slideshow. Is there a way to do this? So far I have figured the best way around this is to have a GIF as a background image that says the loading message, and then once the slideshow loads over the top its fine, however im guessing this is'nt the right way to do this. I am using this slideshow set to just loop:
[URL]
I am open to using other similar slideshows if there is one more suited.

I'm working on a web map, in which you click on a building to open a pop-up with a photo of that building in the window. Rather than use a generic pop-up, I've styled it to look similar to the parent page. Since my map contains over 200 buildings, initially this meant creating over 200 separate html pages with the image source and dimensions for each building photo. That's clearly very inefficient and not a process I want to duplicate! Therefore, I needed some dynamic code to generate the content in the pop-up.
I successfully used a cookie to pass a building ID variable to the pop-up and use that to grab the associated photo from a directory and that worked fine. However, I ran into problems because the photos are not identical in size, and I also needed to get the image width and height. I tried preloading the image using a standard image caching script and used that to obtain the width and height of the image. Then, I used document.write to place those variable in the <img> tag and place the photo on the page.
The problem is that the cached image will not display on the page when it loads, only if I hit refresh. Can anyone tell me how to get around this? Here's the code I'm using. I call this function inside a <p> tag in the body of the page:
if (document.images) {
bldg = new Image();
bldg.src = "../../Columbia/bl/bl_" + BldgId + ".jpg";
theWidth = bldg.width;
theHeight = bldg.height; }
function showImage() {
var photoSrc = "<img src='../../Columbia/bl/bl_" + BldgId + ".jpg'";
var insertPhoto = photoSrc + " width='" + theWidth + "px' height='" + theHeight + "px' alt='" + BldgId + " Photo not available' />";
document.write(insertPhoto);}
Is there another way to get the image's dimensions BEFORE I place it on the page?

Piece of simple javascript that I can't get to behave. It's a basic image/slideshow.....
in the <head> section.....
<script type="text/javascript">
var image1=new image() image1.src="../Images/WebSite/HomePage/HpLavender.jpg";
var image2=new image() image2.src="../Images/WebSite/HomePage/HpCreams.jpg";
var image3=new image() image3.src="../Images/WebSite/HomePage/HpBathMelts.jpg";
var image4=new image() image4.src="../Images/WebSite/HomePage/HpCandles.jpg";
var image5=new image() image5.src="../Images/WebSite/HomePage/HpMostlyMen.jpg";
</script>
And then in the body:
<img src="../Images/WebSite/HomePage/HpLavender.jpg" name="slide" border="0" alt="">
<script type = "text/javascript">
var step=1;
function slideit() {
if (!document.images) {return}
document.images.slide.src=eval("image"+step+".src");
if (step<5) {step++}
else {step=1}
setTimeout("slideit()",2500);
}slideit();
</script>
The coding seems to be tripping up on the line:
document.images.slide.src=eval("image"+step+".src");
(I inserted document.write statements before and after this line and only received the 'before' statement).
The image before the javascript kicks in
<img src="../Images/WebSite/HomePage/HpLavender.jpg" name="slide" border="0" alt="">
displays fine - and the images listed in the header are correctly named.

I tried assigning 2 error classes to an error message (as a span), but when the empty field was fixed, the error message wouldn't disappear.
$
(
"#testForm"
)
.
[Code]....
With 1 error class it works fine, but adding a second one makes it fail. Here are some links, just hit the submit button a few times on each one to see what I mean
2 classes: [URL]
1 class: [URL]

I have very basic javascript skills, just started looking into jQuery and jQueryTools to enhance my websites. I have been coding PHP for about 1.5 years.I have a php form with which users can update their purchase order before making a final confirmation and payment.
Thought it would be nice if, instead of using php for redirecting to a success/fail message in a separate php file and redirecting again back to the form with a 3 second delay, I could get a jQuery script to pop up with a success/fail message, so avoiding all the clumsy php redirecting and page refreshing.I've searched for plugins, but they all act on event listeners attached to a submit button or other clickable html element.Ive searched the net for ages and can't find an easily understood explanation and complete example, where a jQuery pop up notification is displayed in response to a php script executing a db update.

I found this slide show [URL]. I got it to work on my website [URL] using Firefox, but when it is viewed in Internet Explorer it will not work. Second question, When the slide show gets to the last image, after the last image all photos disappear and it resets itself changing the format of the webpage. Any way to not have the images disappear while it loops itself or is there a code to have it stop on the last photo and not loop.

I've been looking at all the various image replacement techniques..and they all seem unnecessarily complicated. I came up with:
function replaceLogo() {
document.getElementById('header').innerHTML = '<img src="/images/logo-tci.gif" />'
}
It's just replacing the layer contents at a very basic level.
This works just fine, I'm just wondering how well supported it would be across different browsers. Anyone know of a table of browsers that support innerHTML or see potential cross-browser issues with this technique?

I'm not sure if what I'd like to do is possible, but it seems like it should be easy to do.
The website (and specific page I'm inquiring about) is
What I created is a list of projects, and upon rolling over a project name, an image appears that relates to that project on the right. Simple CSS trick.
In addition to this, I'd like for when the page first loads for there to be a placeholder image on the right hand side, and after the user hovers over the first project, the image would disappear and not return.
I think this makes sense to do so the user has something to look at before they start hovering over project names, instead of there just being a giant blank space.
Is this possible? It seems like it should be easy, but I really know nothing about Javascript.

Given this simplified to the min constructor:
function jsFileManager(mode) {
this.mode = mode;
}
If there a way to make jsFileManager.mode property as final protected.
Other words, it can be set only once diring the objects initialization
and it is accessible only to the inner methods of jsFileManager

In my website I constructed a script that changes the image.sources of several images. The changes are made by calling a JS-function. The function is invoked by selecting an option in an html-form. In my second post below I pasted the code.
The problem is that each time the images are changed the browser starts to load them all again, although all images were PRELOADED in the <head> section of my HTML page. It takes time every time a user invokes image changings, and also the visual effects are worsened.
How can I prevent the browser from loading the images again each time?

I apologize for the length of the page below, but I've tried
to whittle it down as much as I can. The problem is that
Netscape 6.1 on my Win 2K Pro machine is disappearing
the final row of the table.
Opera 7.01 and IE 5 and 5.5 are both OK with the page, and
the offending line is right before the commented out alert line,
but I have been unable to figure why it's happening.

I'm multiplying 3 drop downs to give me a total sq ft. I then want to take that variable and multiply it by a fixed number. i.e. qty*width*length equals a total of 8 sq ft, then take that 8 and multiply it by a fixed number (8*1.75), I want it to calculate without any submit buttons and show the total sq ft and the final value.

I ended up having to preset style with JavaScript.
Here is what I did.
CSS Code:
JavaScript Code:
HTML4Strict Code:
The first time I hit toggle, nothing happens. The second time I hit toggle, the hidden list appears, but only because I used JavaScript to set the display property.
My workaround is to do this in the HTML after the element to be toggled.
JavaScript Code:
Putting this code in the elements onload event property didn't work either, which I found odd, but I read that it was not the recommended way of doing this.
I can't figure out why the CSS declaration didn't load into the JavaScript HTML DOM. I suspect it's some sort of order of execution thing, like the difference between the two following function declarations.

I have a script one of my pages which is designed to prevent a user from selecting the same option from a drop down more than once. Here is the script:
Code:
function changeSelect(sel) {
option = sel.selctedIndex;
var sels=document.getElementsByTagName("select");
[Code]....
Here is the basis: A user is greeted with a page of blank fields. On the right is a drop down menu which has the select options you see. The user enters the address of a few DNS servers, then selects their main and least favorite DNS of the group. If there is a "Main DNS" already selected, it will blank the originally selected drop down, and fill in the newly selected drop down.
The problem I'm having, is when the user calls their settings back, the PHP will load the proper "main" and "last" options, but I have to select two more to get it to blank. I know this is because the script is called with an "onchange" function, but I've tried using "onLoads" and I've also tried making a quick function to "select" the option, but to no avail.
