JavaScript - Multiple Slideshows
Hi,
I am new to Javascript, but am trying to work with a bit of script I found online to create a crossfade slideshow for my page. The problem I am having is that I want to have several slideshows on my page. On it's own, a single slideshow works fine but when I add a second (and do my best to hack the code with my limited knowledge) only one slideshow will work, or sometimes neither. I found the article from this site that explained about event conflict, but the example used looked quite a bit different to mine. Here is the js file I started with Code: window.addEventListener?window.addEventListener('load',so_init,false):window.attachEvent('onload',so_init);
var d=document, imgs = new Array(), zInterval = null, current=0, pause=false;
function so_init()
{
if(!d.getElementById || !d.createElement)return;
css = d.createElement('link');
css.setAttribute('href','slideshow2.css');
css.setAttribute('rel','stylesheet');
css.setAttribute('type','text/css');
d.getElementsByTagName('head')[0].appendChild(css);
imgs = d.getElementById('rotator').getElementsByTagName('img');
for(i=1;i<imgs.length;i++) imgs[i].xOpacity = 0;
imgs[0].style.display = 'block';
imgs[0].xOpacity = .99;
setTimeout(so_xfade,3000);
}
function so_xfade()
{
cOpacity = imgs[current].xOpacity;
nIndex = imgs[current+1]?current+1:0;
nOpacity = imgs[nIndex].xOpacity;
cOpacity-=.05;
nOpacity+=.05;
imgs[nIndex].style.display = 'block';
imgs[current].xOpacity = cOpacity;
imgs[nIndex].xOpacity = nOpacity;
setOpacity(imgs[current]);
setOpacity(imgs[nIndex]);
if(cOpacity<=0)
{
imgs[current].style.display = 'none';
current = nIndex;
setTimeout(so_xfade,3000);
}
else
{
setTimeout(so_xfade,50);
}
function setOpacity(obj)
{
if(obj.xOpacity>.99)
{
obj.xOpacity = .99;
return;
}
obj.style.opacity = obj.xOpacity;
obj.style.MozOpacity = obj.xOpacity;
obj.style.filter = 'alpha(opacity=' + (obj.xOpacity*100) + ')';
}
}
This uses a couple of CSS files and then you just add a div=rotator on the html to add the object and then the images and links within that div. If anyone can help, or perhaps give me a better solution, I'd be most grateful. Thanks Similar TutorialsI am pretty new to JavaScript, so I apologize if this is a stupid mistake. I am using this code, but trying to have several slideshows on the page. I have set up two to test it, and one works while the other just displays a static image. What is the best way to do this? Do I need to repeat the script code in the head? Thanks in advance for any help.

On the page I am designing I have 2 js slideshows. The first one slides images right to left and the second contains the caption for the image and fades in and out. Here is an example of the exact concept of what I'm trying to do: http://designsensory.com/ The problem I'm having is that the slides will not maintain the same timing and I'm not sure how to create a single user control that controls both slideshows simultaneously. I would really appreciate if someone could help me solve the issue or at least point me in the right direction (tutorials possibly?). Here is the JS code: Code: <script type="text/javascript">
var firstreel=new reelslideshow({
wrapperid: "myreel", //ID of blank DIV on page to house Slideshow

Once again, Thanks alot for any assistance I just created a slideshow that is working (finally).

I am trying to run three continuous slideshows on the same page. The script I am currently using is written below. Can it be modified so I can run all three slides at once on the same page? <html> <head> <script type="text/javascript"> <!-- var image1=new Image() image1.src="firstcar.gif" var image2=new Image() image2.src="secondcar" var image3=new Image() image3.src="thirdcar.gif" //--> </script> </head> <body> <img src="firstcar.gif" name="slide" width="100" height="56" /> <script> <!-- //variable that will increment through the images var step=1 function slideit(){ //if browser does not support the image object, exit. if (!document.images) return document.images.slide.src=eval("image"+step+".src") if (step<3) step++ else step=1 //call function "slideit()" every 2.5 seconds setTimeout("slideit()",2500) } slideit() //--> </script> </body> </html> Hi, I am wanting to do menus and image slideshows using javascript because my existing flash menus and slide shows no longer work on many newer devices. To save time learning all about Javascript, I purchased WoW Slider and Apycom Menus, two programs that do it all for you. Independantly both programs work perfectly, however if I use both programs together on the same website, as soon as I add my image slider it messes up my menu for that page. the menu item colours and bouncy effects when I do a mouseover on menu items no longer work correctly. Example http://www.dorset-self-catering.com note the menu working correctly on mouseover, then go to second page called "Information", this page also has a slideshow and if you now do a mouseover on the menu, you will see that all the nice properties no longer work. Is anyone able to offer some advice please. David Priest Random Image Slideshow (I want two!?) Hi I have use the code from he http://www.javascriptkit.com/script/...domslide.shtml (which works well for me) Can anyone tell me how I can get a second other random image to display on the page beside the first? I cant work it out. It seems I cant run the script twice? Here's my page: http://www.bookmarkpeople.com/chillax2.htm Any help much appreciated? A bear of simple brain. Jules. Hi, I hope someone can help me. I'll be honest and say I don't know much about javascript, but am fairly comfortable in html. I am building a website that will have multiple image swaps on multiple pages. I am building this in wordpress, and I'm guessing that means my approach will be different than if I wasn't using wordpress. Here's how one page would work: There are 10 images shown. 1,2,3,4,5,6,7,8,9,10. When number 1 is clicked on, I want a new image - 1a. When 2 is clicked on, 2a. So there are 20 different images in all on a given page. Also, I want the user to be able to click on the image again to restore the original image. I would prefer onclick to onmouseover. There will be literally dozens of pages like this on the site, managed by wordpress, so hundreds of images to swap. Basically the first image is a question - the second image is the answer. Is this possible? I don't know how to work with timeouts. I have a simple blinking image. but I'm not sure how to set multiple timeouts? Basically I want the image to blink to another one for 400, then return to the first image for 5000 here's the basic starting point I have: Code: <script type="text/javascript">
var img_off = new Image(); img_off.src = 'images/blink.png';
var img_on = new Image(); img_on.src = 'images/orho2.png';
function blink() {
var e = document.getElementById("blinking_orho");
e.src = (e.src == img_on.src) ? img_off.src : img_on.src;
setTimeout("blink();", 5000,);
}
</script>
FYI: THIS IS NOT HOMEWORK! Hi all, I am trying to make an all-in-one function that can use local storage and provide 4 functions: (1) read data (2) write data (3) erase specific data (4) erase all data Here's the code block I have (with alerts in place of the local storage code for debugging): Code: var storage = function (name, value) {
if (name) {
if (value === null) {
return alert('erase');
} else {
if (value != null) {
return alert('write');
} else {
return alert('read');
}
}
} else {
return alert('nuke');
}
};
I want to use it like this: storage(); - erases ('nukes') everything storage('abc'); - reads data stored as 'abc' storage('abc', 'newvalue'); - stores 'newvalue' as 'abc' storage('abc', null); - erases data stored as 'abc' only It seems to work, but I have a funny feeling about trusting the difference between "==" and "===" to make it work. Am I wrong? Is there a real difference between == and === and am I doing this correctly? Thanks! -- Roger Hey guys, I'm a noob with javascript and I only know simple HTML coding, so I have become stuck. I can program in other languages though, so I understand the principles. That being said, I have become stuck with something. My aim is to have a series of page where text is displayed, and then two or more buttons. Once a button is clicked, I want the screen to clear and it displays the next lot of text, followed by some more buttons. Once they are pushed, it continues on. So basically, each section has its own code that it pushes, plus its own buttons which lead to other sections. I am not trying to make a choose your own adventure book, but the layout is basically one of these. I can do this in another language by simply having a few sections. Inside each section, it retrieves the option and proceeds. However, when I am trying to do this, I am getting confused. The way my other programming experience tells me to write it, I would write a function which is called for each section, and it would display the text, the buttons, and return to the main function in the program. However, because the buttons are in HTML, I cannot put code for the new buttons instead the functions. If I put the code inside the body of HTML, it will automatically be displayed. I cannot write an if statement to determine which buttons are displayed. Can you please give me some advice around this? I hope I have made myself clear enough to be understood!! One other thing I should mention, I really want to be able to do this in a single HTML file instead of calling other files. I think this would work fine by using frames and multiple HTML files, but I would prefer not to unless I really need to. One file would be much better for me. Thanks! Below is the basic code I am working from. It displays the first section with some text, displays two buttons and it goes to the next section on a button click. Code:
<html>
<head>
<script type="text/javascript">
function button1()
{
document.write("Button 1 was pushed. Insert text here. Choose from two new buttons below:");
}
function button2()
{
document.write("Button 2 was pushed. Insert text here. Choose from two new buttons below:");
}
</script>
</head>
<body>
<form>
<input type="button" value="Button1" onClick="button1()" />
<input type="button" value="Button2" onClick="button2()" />
</form>
</body>
</html>
hi its me again. i was using the data that I pulled out from my db and then provide a push button weather to lock it or not but the problem is, the js code doesn't mouse over on the next button, here's the js code Code: var once = true;
function asktolock(){
if(once){
document.getElementById('locker').value = "Lock Me ?";
}
}
function lockme(){
document.getElementById('locker').value = "Locked";
once = false;
}
and here's my html with php/js code PHP Code: <?php foreach($task->result() as $row): ?> <tr> <td><?php echo $row->title; ?></td> <td><input type="button" id="locker" value="unlocked" onmouseover="asktolock()" onclick="lockme()" /></td> <td><?php echo $row->assign_to; ?></td> </tr> <?php endforeach; ?> if I will put an "onmouseout" and feed it with a function like this Code: function passby(){
document.getElementById('locker').value = "unlock";
}
the clicking function won't work anymore, what's the best thing to do? here is my issue... i have an object and i need to call two functions. i need the onclick="something" to call a server side function and then i need another onclick="something" to call a javascript funtion... the problem is you can only have one "onclick" (similar to having one "class")... how can I set up an onclick that will call both my serverside function and my javascript function... I realize this is not specifically serverside section of forum, so pretend I am asking how to call two separate javascript functions with different names the item in question is here Code: <asp:Button ID="btn_gen1" runat="server" Text="InterventionCentral" class="show"
onclick="btn_gen1_Click" onclick="autohide" onmouseover="details_visible(1)" onmouseout="details_hidden(1)" />
just showing this to clarify that javascript does work with the asp and my mouse functions are working fine... my asp onclick works as well.. i can remove the asp and leave the js and it will work, but then all the stuff i do server side for the onclick goes away is this able to be done? this is for dev testing and i will eventually run into the same problem of needing to call two separate javascipt functions via onmouseover and also onmouseout I have a page of dates in a form field which currently are being entered manually and wish to have a calendar pop up for each one to make it a bit easier. i have managed to use a calendar routine 'tigra calendar' i found online but now after working out not to get it working within my own template i faced the problem on multiple date fields. i currently use a numbers field 1-10 or how every many there needs to be on that page. but how would i integrate this within the coding from 'tigra calendar' can anyone suggest a better way to do this. if needed i can sort out a zip file of the files i have for tigra calendar. plz i want to know how to make the effects that exists on this link in the upper part : http://www.masrawy.com/new/ 1-) changing color when pressing on the color 2-) changing font (+) to increase it (-) to decrease it (N) to set it to the normal style 3-) decrease and increase the width of the page (from كبر حجم الصفحة or صغر حجم الصفحة ) can anyone help me in doing this task????? Im having problems with this code working as it should. the top banner is supposed to cycle the second banner is supposed to be random the 3rd is a slide show that is supposed to work in order Everything works in random order.

I have a quick question with multiple array and random numbers. If i generate my random numbers in one array, how would i take a selection of those numbers and put them in another array? Ex: array 1: 25, 34, 38, 40, 22, 49 want to move numbers between 30 and 50 to another array. array 2: 34, 38, 40, 49 is it as simple as for loops and if statements setting the conditions? do i use a sorting method? (selection? bubble?) any help would be appreciated. I have what would seem like an easy task, but is not working out that way. I have a basic html form with multiple user input boxes. Upon the submit button being clicked it validates the input with javascript and then emails the information with the forms mailto. What I need it to do, is email everything but the information in one textbox to a group of recipients, and the email all of the items to a different recipient. This need to be done to prevent certain induviduals from seeing certain items filled out on the form. I know this can easily be done in asp, php, or a server-side client of the sort, but we do not have access to any resources like this in this area of the company. I'm open for any suggestions you may have. Thanks ahead of time. |
