Do While Loop - Modifying Rotate Image Script
Jan 11, 2011
I found a simple image rotating script online and it works like a charm. I have several business logo images on my site and the script randomly selects and displays the images. However, since it selects the images at random you don't get an even mix of logos. Sometimes one or another logos will show up more frequently than others. To avoid this I added a simple DO-WHILE loop with an array. Now it will go through my whole list of logos once in random order, which is just what I want to happen. The trouble is, once it goes through the list of logos once, it freezes up.
I want it to reset after it goes through the whole list. Then it can keep running indefinitely. I tried adding a simple increment counter (counter++; ) and an IF-THEN line in the getNextImage() function so when the counter reached the number of images it would restart via the restart function, but now the images won't show up at all. I tried adding the counter++ at different locations but the result is the same: it doesn't work, so I took it out. Here is the site it will go on, complete with two rotating images (I doubled up on the rotate code) which rotate completely randomly. The one in the center doesn't change: [URL].
Here's a working, stripped down version of the code which shows the images at random: [URL]. And here's the same code with the DO-WHILE loop and the myArray added, which rotates once then locks up:
Code:
<html>
<head>
<title>test</title>
<link rel="stylesheet" href="file:///D|/Downloads/dw_rotate/css/ex.css" type="text/css" />
<script type="text/javascript">
var interval = 2;
var random_display = 1;
interval *= 1000;
function restartImage() {
var counter = 0;
rotateImage('rImage');
} .....
Any way on adding something to count the number of times the images are displayed, and resetting the count once the total number of images has been reached.

I've been searching for a way to rotate an image a div say 90 degrees when a link is clicked, but can not seem to get it to at all. Here is some code I'm trying at the moment amongst many others, using thejQuery Rotateplugin.
$('#canvas a').click(function() {
$('#circle').rotateLeft([angle=90]);
return false;
});
Edit: I can get it to kind of work with css3, although it doesn't animate, and it only rotates once. I would like to keep rotating each time a link is clicked.
$(document).ready(function(){
$('#canvas a').click(function(){
$('#circle img').css({"-webkit-transform" : "rotate(+45deg)"})
});
});

I am building a site to replicate an existing site for a non-profit.[URL] want to have a rotating image on their home page, and I have it working using the following jQuery Code:
<script type="text/javascript">
$(function() {
// create the image rotator
setInterval("rotateImages()", 4000);
[code]....
The problem is that I can't figure out how to clear the previous slide's decription (in the <p> tag of each Div). At present the descriptions do rotate, but they are all visible since they are within the stacked Div's. How can I get the descriptions to show and hide in sync with the images?

I'd like to have something similar to the rotating images and text on my website. The website that I would like to mimick is: [URL]
You can see that the images move but there is still text over the image that I can click on. How would I go about doing something similar to this on my website. I'm guessing it's a combination of Javascript and CSS but I figured I'd start here.

How to get background images to rotate with a fade in a header without using an image in div in the body. A combination of javascript and CSS -- not sure if this is the correct forum or not? I can achieve an image changing/rotating in a div using the code just below. But I have to refresh the page for the image to change.
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "[URL]">
<html lang="en"><head>
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1">
<title>Rotate Images</title>
<script type="text/javascript">
var backgroundSrcs = new Array("list-of-images");
function pickimage() { .....
And I can get the image to rotate, change on its own, with the javascript below but have to do it using through an img div, a place-holder.
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "[URL]">
<html lang="en"><head>
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1">
<title>Rotate Images through img tag</title>
<script type="text/javascript">
var rotatingImages = new Array("../list-of-images"); .....
So what I really would like to do is have the image rotate through the div and not have to have the img tag present. I haven't even tackled the fade but have some thoughts about this. Since it's the header div I want to do the fading not the img tag, I'm thinking the way to make the fade work will be the same.

I have an assignment doing something simple with javascript, but I'm lost because I can't figure out what I am doing wrong. This is the assignment. I'm using the code provided and modifying it as stated, but I cannot get the image to move.

I created this click script to rotate through a few images and I just decided that it might be good to auto rotate if no one is clicking on it.

I am building a site with ads that I want to rotate positions (this way I can keep it fair for advertisers- the bottom ad rotates up to the top) upon refreshing the page, searching through the site, or each time the user visits. I have three images (sponsor1.jpg, sponsor2.jpg,sponsor3.jpg) that are always displayed vertically in the right banner. I assume this is just a simple javascript slideshow tweaked a bit but can't figure it out.
I find plenty of js scripts that will rotate several images through one image location, but I want image POSITION 1 to start with sponsor1.jpg, image POSITION 2 to start with sponsor2.jpg..and so on... then upon refreshing the page image POSITION 1 is holding sponsor2.jpg, image POSITION 2 is holding sponsor3.jpg... etc

had this in browsers areas but people told me I should put it here in Javascript because more people here would probably have seen it before and know why it happens. I have basic Javascript that rotates images. I've noticed any kind of Javascript code that rotates images has this same problem only in Mozilla. When the images rotate in Mozilla in between the rotations, Mozilla browser adds a little colored square that represents a blank image that are able to be seen does anyone know why Mozilla Browser adds that? For example when looking at this page in Mozilla can see it. if you know if this is some Mozilla problem with Javascript and images. Doesn't happen with IE and other browsers shows the images only and nothing else.

This isn't working and I can't figure out what I'm doing wrong:
var c_imgs = new Array(
'images/champascari.jpg',
'images/champfangio.jpg',
'images/champhawthorn.jpg',
'images/champhill.jpg',
'images/champsurtees.jpg',
'images/champlauda.jpg',
'images/champschumacher.jpg');
var pre_img;
for (var i = 0; i < c_imgs.length; i++)
{
pre_img[i] = new Image();
pre_img[i].src = c_imgs[i];
}
If this code is correct, should I put it in a function and then call for
it ?

I am trying to use a for loop to call images of custom text. For example, I have images named uppera.png and lowera.png for a custom font. I need the image of the letter to show up as they type into a text area, but also have backspace work correctly to delete the last image added. Here is the code I have thus far:
<script type="text/javascript">
function callimage() {
var chars = document.getElementById('userinput').value.split("");[code]....
When I test this out it takes the previously entered text and adds it to the new text and combines them. For instance if you entered "a" it would show up as "a"; if you entered "a" again it would show up as "aaa" and then "aaaaaa" and so on. Also, it will add the existing characters again if any key is pressed, like just shift. I think I would need to write an else statement to fix that part, but I don't know what to put there, either.

I want to build a loop, which cycles through a set of images and displays each image for a few seconds. In Firefox everything works fine, IE6 also executes the code but gives an script error in the status bar ("not implemented"). The relevant line of code is in red in the code below.
What could cause this ugly error in IE?
Code:
var imgpath = "imgtest/";
var errpic = 1;
var maxpic = 5;
function imgloop(actno) {
if(actno==maxpic) {
actno=1;
} else {
++actno;
}
preload(actno);
}
function imgshow(actno) {
document.mainpic.src = imgpath + actno + ".jpg";
imgloop(actno);
}
function delay(actno) {
setTimeout("imgshow(" + actno + ")", 5000);
}
function preload(actno) {
img = new Image();
img.onload = delay(actno);
img.src = imgpath + actno + ".jpg";
}

I'm trying to change the src attribute of an image within a loop and I only get the last image in the sequence. I've put a break-point and I can see that listItems contains the right source for all my 3 images, but I only see the last after the initial change from the original source. pausecomp is a delay function.Here's the code for that loop (this is part of a bigger program within SharePoint)

I wanted to make it loop from image 1 to image 7 when the mouse pointer is on the image. So basically your mouse pointer goes in and out.

Code:
If I use the return keyword to exit the function/loop after they set up the first image rollover, it works perfectly on the first image. However, if I comment out the keyword, theId, which is the variable that contains the id of each respective image (which is the same id of the containing link with "1" added to the end) becomes "undefined" (as my JavaScript console says), and thus none of the images work as they're supposed to work. Not even the first one.

I have the following:
<tr onMouseOver="alert('Over a row')">
and I want to modify the event to be:
<tr onMouseOver="alert('Over THIS row')">
in other words reaching into the event, and changing some part of it.
I have tried walking through the attributes of the <truntil I reach
the onclick, then changing its value, but that throws an error.
