JavaScript - Slideshow Issue

Hey im looking to get 3 slide shows on 1 website (coded in php).

I need the slide shows to all show different images however all change images at the exact same time and have the exact same layout... how can i do this?

This slideshow has a drop down menu that lets you go from one picture to another.

Can someone help me modify it so that instead of a dropdown menu i have a list of numbers (horizontally,not vertically)?

I know absolutley nothing about javascript. sorry.

Thanks programmers!

I am having a problem with my homework assignment and can not figure out the problem. Debug comes back clean and I am stumped on this project for several hours. I hate asking for help and like to figure it out on my own, but I can not seem to know what the problem is. I have done alerts in my blocks of code and everything is coming back.

Here is the book and the case problem I am on:
http://books.google.com/books?id=BeE...page&q&f=false

Basically the images is not loading up, or anything is happening.

//EDIT : I have the function setup() onLoad in the body ( body onload="setup()" )

Here is my code:

FileName: flibrary.js

Code:

function getStyle(object, styleName) {
   if (window.getComputedStyle) {
      return document.defaultView.getComputedStyle(object, null).getPropertyValue(styleName);
   } else if (object.currentStyle) {
      return object.currentStyle[styleName]
   }
}

// step 3
function addEvent(object, evName, fnName, cap) {
   if (object.attachEvent)
       object.attachEvent("on" + evName, fnName);
   else if (object.addEventListener)
            object.addEventListener(evName, fnName, cap);
}
//step 4
function addEvent(object, evName, fnName, cap) {
   if (object.detachEvent)
       object.detachEvent("on" + evName, fnName);
   else if (object.removeEventListener)
            object.removeEventListener(evName, fnName, cap);
}

Code:

var mySlideShow = document.getElementById("slideShow");

var imageArray=new Array(); 
imageArray[0]="url(images/Slide1.JPG)";       
imageArray[1]="url(images/Slide2.JPG)";
imageArray[2]="url(images/Slide3.JPG)";


var imageIndex = 0;

var leftArrow = document.getElementById("left");
var rightArrow = document.getElementById("right");

mySlideShow.style.backgroundImage = "url(images/Slide1.JPG";


function changeRight  () {

mySlideShow.style.backgroundImage = imageArray[imageIndex];
imageIndex++;


	if (imageIndex >= imageArray.length) {
	imageIndex = 1;


	
	}
	
	console.log(imageIndex);
	
}


function changeLeft  () {

mySlideShow.style.backgroundImage = imageArray[imageIndex];
imageIndex--;
console.log(imageIndex);
	
}




rightArrow.onclick = function() {
	
	changeRight();
	
	}
	
leftArrow.onclick = function() {
	
	changeLeft();
	
}

So what I am trying to do here is basically a slideshow. When I click on the left button it goes backwards and when I click the right button it goes forward. The problem arises when I click on the left arrow. It doesn't act as I want it to and I need some help. I want to remove one from the image index but imageindex--; doesn't seem to work.

Any help would be awesome.

Solved

I worked a lot with a friend to change the code, and it's almost there. The next and last buttons still work. The Start buttons is titled 'wri' and the latest button is titled 'end'. The end button does not work. Before I added the end button, the start button worked, but now it sends you to the image alt. Any ideas on what went wrong?

Code:

window.onload = initLinks;

var myPix = new Array("comic/Issue1_Page00.gif","comic/Issue1_Page01.gif","comic/Issue1_Page02.gif");
var thisPic = 0;

function initLinks() {
	document.getElementById("prevLink").onclick = processPrevious;
	document.getElementById("nextLink").onclick = processNext;

}



function processPrevious() {
	if (thisPic == 0) {
		thisPic = myPix.length;
	}
	thisPic--;
	document.getElementById("myPicture").src = myPix[thisPic];
	return false;
}

function processNext() {
	thisPic++;
	if (thisPic == myPix.length) {
		thisPic = 0;
	}
	document.getElementById("myPicture").src = myPix[thisPic];
	return false;
}

// Load Images
if (document.images) {  

  writeImg = new Image();      
  writeImg.src = (comic/Issue1_Page03.gif);
  
}

function imgOn(imgName) {
  if (imgName == 'end') { document.strip.src=eval("writeImg.src"); document.txtwriteImg.src=eval("txtwriteOnImg.src"); return true;}

  return false;
}


// Load Images
if (document.images) {  

  writeImg = new Image();      
  writeImg.src = (comic/Issue1_Page00.gif);
  
}

function imgOn(imgName) {
  if (imgName == 'wri') { document.strip.src=eval("writeImg.src"); document.txtwriteImg.src=eval("txtwriteOnImg.src"); return true;}

  return false;
}

Hello everybody!

first of all I must specify that I don't know almost anything about javascript... I'm trying to introduce a javascript slideshow (I found a free one) on our website and I have a problem:

As you can see here on the bottom of the page (http://www.comelity.com/en/pages/about-us.php), when the slideshow changes image, it puts a link over the image without any reason and if you click on the image it reloads the page... I would like to remove this link, but I'm not able... Does anyone know how to solve the problem? I can send the javascript slideshow if you want...

Thank you very much!

S.P.

hi evey one

I've made my content for each slide and just need a script that change these content

I have been working on a picture slideshow w/ a caption, and (due to being an extreme amateur) I cannot get it to work just right. I have the slideshow going, but I can't get the caption to stay on the right side of the photo, while keeping the layout fluid. I would also love to add a pause, forward, and back button, and I have tried several free slideshow generators but either they don't work or they don't produce what I'm after.

Here is my code so far.

Javascript:

var BaseDirectory = 'http://s200.photobucket.com/albums/aa216/Jilldear/';

  ShowSlide(ImgPtr);
}
onload = function() {

Code:

<div style="height:300px;width:398px;">

<img src="" alt="" border="1" id="mypic" name="mypic" alt="" height="300" width="398">

</div>

I would LOVE for the finished slideshow to look somewhat like the one on this website: http://www.equisearch.com/ but I know this is a lot to ask

Thanks so much in advance!!!

Hi everyone,

I'm pretty new to JS and I was wondering if anyone could put me on the right track to developing a slideshow which you can flip between the images manually or let it run through itself (and preferably contain links to other pages).

Basically, like the one at the top of the Valve website:
http://www.valvesoftware.com/index.html

Thanks all

I have created two pages. One with a selection of images one with a working slideshow.

How do I get it that a user can select 4 images that are then transferred to the slideshow and played in that slideshow?

I appolgise if this is a simple fix but I am very new to JavaScript. Thank you all in advance

Hi there,
I have an issue with my slideshow in IE7. There is a transparent grey box that slides upwards with text on the bottom of the slideshow. In IE7 the grey box does not go right across to the right hand side it leaves a small gap. It does this in IE7 compatability mode in IE9 and i've tried the proper version of IE7 too.

My site is located at http://www.passmarkdrivinglessons.co.uk

The slideshow I used in my site is from here http://www.queness.com/resources/htm...slideshow.html

Can any help me to solve this issue, thanks

I have a real estate JS slideshow that I would like to modify but have no experience with Javascript. Here is the test link to the slideshow in action:

http://coastalrealestateconsultants.com/slideshow.html

I want to re-position the three line link caption below the slideshow (price and address) so that it is in a semi-transparent box up in the image slideshow, say centered near the bottom of the image.

Can anyone help me? Thank you in advance.

Hello all, I'm having problems with Javascript coding, and was hoping someone could help me out. I have a site using prestashop -

http://www.dipsydaisy.co.uk

The slider at the top, I am having problems with..at the moment, it is scrolling auto, but randomly. I need to have this scrolling through images 1-3, then back to the beginning, and on a continuing loop. Also I would like to apply a fade effect on each slide, but being a total novice, not sure if this can be done?...Here is the coding I have applied to get autoscroll:

Code:

 intervalID = setInterval(makeScroll, 4000);
function makeScroll()
{
    var rand_no = Math.floor(11*Math.random());
    if (rand_no < 5)
        {
            $('#slides > .next > a').click();
        }
    else
        {
            $('#slides > .back > a').click();
        }

Hope someone can help! Many thanks.
