JavaScript - Slideshow - Images In A Folder

I recently installed a dynamic slideshow on my server and tried eliminating the background from "black" to "none" in the fadeslideshow.js so I could use transparent images to reveal the blue background on my site, but for some reason slide 1 stays on screen when switching to slide 2... not sure what to do, would appreciate any help. Thanks, Josh.

PLEASE! I NEED HELP!
I inherited this problem from a client who insists on keeping this template. I've got all of the images in the correct folder, the slideshow css is correct, but I'm not sure how to edit the Slideshow.js file to show the 2 additional images. The first 3 images work perfectly. I was able to swap custom images for the original images without a problem.
Here is the Slideshow.js code

Code:

 var $$ = $.fn;

$$.extend({
  SplitID : function()
  {
    return this.attr('id').split('-').pop();
  },

  Slideshow : {
    Ready : function()
    {
      $('div.tmpSlideshowControl')
        .hover(
          function() {
            $(this).addClass('tmpSlideshowControlOn');
          },
          function() {
            $(this).removeClass('tmpSlideshowControlOn');
          }
        )
        .click(
          function() {
            $$.Slideshow.Interrupted = true;

            $('div.tmpSlide').hide();
            $('div.tmpSlideshowControl').removeClass('tmpSlideshowControlActive');

            $('div#tmpSlide-' + $(this).SplitID()).show()
            $(this).addClass('tmpSlideshowControlActive');
          }
        );

      this.Counter = 1;
      this.Interrupted = false;

      this.Transition();
    },

    Transition : function()
    {
      if (this.Interrupted) {
        return;
      }

      this.Last = this.Counter - 1;

      if (this.Last < 1) {
        this.Last = 3;
      }

      $('div#tmpSlide-' + this.Last).fadeOut(
        'slow',
        function() {
          $('div#tmpSlideshowControl-' + $$.Slideshow.Last).removeClass('tmpSlideshowControlActive');
          $('div#tmpSlideshowControl-' + $$.Slideshow.Counter).addClass('tmpSlideshowControlActive');
          $('div#tmpSlide-' + $$.Slideshow.Counter).fadeIn('slow');

          $$.Slideshow.Counter++;

          if ($$.Slideshow.Counter > 3) {
            $$.Slideshow.Counter = 1;
          }

          setTimeout('$$.Slideshow.Transition();', 4000);
        }
      );
    }
  }
});

$(document).ready(
  function() {
    $$.Slideshow.Ready();
  }
);

The html code for the pages looks like this:

Hi people, I am using a drupal module, views slideshow, it displays images on my site, the landscape sized images are showing fine, however the portrait images are not centered but aligned left and they look cramped over to one side, I have tried css and its not working for sure, this is the script, Im sorry but I no absolutely no javascript so if anyone can figure this one out I will owe you one. I guess it will need to check for the largest width in the slideshow and then half this for the centre. the link to the file is here aswell http://www.2shared.com/document/3kyc...slideshow.html

Hi

I have set an overall size for the Slideshow 2! div in the CSS file as follows:

.slideshow {
height:250px;
margin: 0 auto;
width:420px;
}

I would then like all the images I use in the slideshow to fit within this area (i.e. 420 x 250). The images will all have a height of 250px, but different widths. For widths less than 420px I would like the image to be positioned centrally in the div along the horizontal axis as in the following image:



for images wider than 420px I would like them to be positioned centrally in the div along the vertical axis as in the following image:



I wonder if it's possible to achieve this with Slideshow 2! and if not, whether another script will help me achieve this?

Thanks

Nick

Alrighty so here's what I have.
Live example:
http://www.thestrikeforum.com/ex/

It's a image slideshow that dynamically gets all the images (via php) in the current directory and puts them into the slideshow array. The array then randomly displays the images in the slideshow (via javascript).

There are 5 images in the folder rotateimage which also has the php script getimages.php in it.

Currently only the first image fades in however I want all the images to fade in as the first one does.

Codes:

Php script that gets all the images for the array:
PHP Code:
<?

//PHP SCRIPT: getimages.php

Header("content-type: application/x-javascript");



//This function gets the file names of all images in the current directory

//and ouputs them as a JavaScript array

function returnimages($dirname=".") {

$pattern="(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$)"; //valid image extensions

$files = array();

$curimage=0;

if($handle = opendir($dirname)) {

while(false !== ($file = readdir($handle))){

if(eregi($pattern, $file)){ //if this file is a valid image

//Output it as a JavaScript array element

echo 'galleryarray['.$curimage.']="'.$file .'";';

$curimage++;

}

}



closedir($handle);

}

return($files);

}



echo 'var galleryarray=new Array();'; //Define array in JavaScript

returnimages() //Output the array elements containing the image file names

?>



Main html page with the javascript:

Hi, thanks for your time first of all-

secondly, I am at a loss for what to do next to get these slideshows functioning. You can see the current iteration he http://www.pauljameswilliams.com/portfolio.html

I am using hte plug in galleria, and I have got it working in a stand alone version with the same images and and folder structure. The difference may be that I have the content nested in these div tags? to create tabs. i really don't know.

Here is the structure within the portfolio tab, under the Identity heading: ( there will be more images once I get this working:

Code:

<div>
<div class="demo">
<ul class="gallery_demo galleria">
<li><img src="images/portfolio01.jpg" alt="Flowing Rock" title="Flowing Rock Caption"></li>
<li><img src="images/portfolio02.jpg" alt="Stones" title="Stones - from Aple images"></li>
<li><img src="images/portfolio03.jpg" alt="Grass Blades" title="Apple nature desktop images"></li>
</ul>
<div class="galleria_container"></div>
<p class="nav"><a href="#" onclick="$.galleria.prev(); return false;">previous</a> | <a href="#" onclick="$.galleria.next(); return false;">next</a></p>
</div>
</div>

I can give you more code if necesary, but I don't want to overwhelm anyone. thanks.

Ok, I am in a small pickle here.

I created a sidebar gadget for work originally with only 4 images that needed to cycle though it. Easy enough script done.

Now they have 6 images that need to rotate through.
Easy enough again, script done.

The issue I have is now I have to re-push this updated html file to all 1000 PC's on my network. Plus every time a change is made I will have to do it again. And we change the images multiple times a month.

So what I need help doing if its possible is to modify the html file i am listing below to have a second IF parameter that not only steps the image but also checks to see if the file is even there.
This is the spot I need help at.
Code:

function slideit(){
			if (!document.images)
			return
			document.images.slide.src=eval("image"+step+".src")
			whichimage=step
			if (step<10)
			step++
			else
			step=1

I wanted to add another part to the IF statement like maybe.
Code:

If (step<10 && file_exists("http://www.akronlibrary.org/Gadget/Gadget Pic 1.bmp"))

Basically a step that checks to see if I have at that moment a file named gadet pic 1. (I would do or statements for all of the file names)


The point is to make this whole thing dynamic, so that I change image 1 on the server and every gadget on every PC looking for image 1 now see the new image. This way I just change the image file name when I want a different image to display. Same thing with the var for the slidelink function. points to a static named html file on my web server and I just change the redirect in the static named html file to go where i want it.

I am by NO means a programmer, I am actually a network admin that came up with this idea and I am trying to fumble through it. Thanks in advance!

Hey guys I'm need to put a photo slideshow on my website with a lot of images. I don't want all the images to download as you come to the website as this would take forever. Are there any pretty simple slideshows that load images just before they are about to come in the view?

How will the program know which image is "about" to come into view? Or are they viewed sequentially? If so there is no need for preloading images to take "forever". Preload the first (say) 5 and then preload the rest while the user is viewing the first ones. Or when each "next" image is selected for viewing preload the next following one.

I have an html page, and I want to use a js from another folder. Can I call a js like this?

in the form of: "E-607-00.pdf"

But i will like to get the first folder (root folder) of the path of the file name that
represent my project number, the path of the file is => u:\1577004\revit\<file name>.rvt

my project number is => 1577004
so the pdf file name will be => 1577004 E-607-00.pdf"

how to get the project number (the first folder of the path)? and put it together with the "E-607-00.PDF"

.... can somebody help me please...!!!


Thank you IN ADVANCE....


function like_REVIT(s)
{
s = cutOffPath(s);
s = cutOffExtension(s);
var ix = s.indexOf(" - ");
if (ix < 0)
return s;
var t = s.split(" - ");
if (t.length < 4)
return s;
return t[2];

Hello everyone I am new to JS and it has been years since I worked with JAVA or HTML but I'm getting back into it for a pet project of mine and could really use some help getting past this small problem in front of me.

ok so here is my issue:
I have an HTML page that will read information from Cells in an MS Excel spreadsheet then will write them to the screen.

This works if I run it localy and use the direct path like C:\MyFolder\ExcelFile.xls

BUT if I try and access the MS Excel spreadsheet from a shared network drive like \\TheComputerName\MyFolder\ExcelFile.xls the JS will not read the file.

SO... I tried to leave the HTML file and the Excel file localy and then tried to open teh HTML file from a shared computer like \\TheComputerName\MyFolder\MyWebFile.html but that wouldn't work ether.


NOW my question to you guys is how can I get my HTML file to read the Excel file from a Network Shared location...
....AND....
....How do open the HTML file from a Shared computer (while still correctly reading the Excel Spreadsheet)

Please help (and use small words and code for my little brain) and thank you.

PS I was wondering if this could even be done in JS, I was wondering if I need to do this in PHP instead which I have NO idea at all.

Hello again...
I have written a custom slideshow script which gets the images from an array...
The script will change the src of a img, which is a fullscreen background.

Now here's the problem, I've been trying to write a function where can define a folder "gallery\test\", and then get all image files in that folder and repopulate the slideshow array.

So, is there a way to scan folders?

I've searched around and found some solutions where PHP is used, but i really want to keep this pure js, if possible (?)

Thanks,

Hi,

I am creating a Search functionality program, which searches a file mentioned by the user on a folder present in a Network folder through File Scripting Object.
The code works fine but the problem is that, when it searches the file on the Network folder the entire HTML page gets hanged and nothing is displayed till the code has finished searching.

I want to update the user with the status of the search process as which folder is it currently searching just the way we have it in the Windows Serach functionality, where the progress is shown on the left side of the window and the files found is shown on the right.

I have tried the solution with having two different frames where the first frame will have the HTML and the JavaScript code to search the file and it will also write the results in notepad file as soon as it gets a matching file name and then proceeds ahead.
The other Frame will read that notepad file and display the data and it will also refresh itself in every 2 seconds. But the page still hangs up since the first frame is not responding.
I have tried the same solution by having two separate HTML pages instead of two frames but no luck. The new HTML page and the previous page both hangs up.

Any Ideas??

hi all, i'm a relatively new user to javascript.

i'm supposed to use javascript to search through a folder that contains many excel files.
the search term is obtained from a front end html form, javascript gets that value, search every single excel file in the folder and see which file has a cell that matches the search terms.

I currently know (sort of) how to search through 1 file. but how do I search through many files? and from what i see from the searching of 1 file, it takes a few seconds to open and close the excel file (located on a network drive). which means it will take a fair bit of time to cycle through 97 excel files. Is there like any searching algorithm to speed up the process?

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.
