i have a requirement that i need to loop through a series of images(say 4 images) with an even inteval of time.I need the first image to come and after some 4 secnds the next image and then the next image.i used 'setTimeout and setInterval' both doesnt seems o be helping me out.pls find the code that i ve written below:

I am working on a small gadget which downloads a series of images from the web and displays the images in a loop. However i am having trouble saving the xmlhttprequest to a file to use later in an array. I have read that it should be easy to save the .png using Scripting.filesystemobject but have been unable to find any information on how to do it.
I've got a selection of 4 images/banners there all the same size and fit into the website layout perfectly, what I'm after is a small bit of java that will change the image from 1 - 4 and then loop to do it again all on a timed delay.
The code I'm using was pulled from a slide show exsample and i've just removed asmuch of the code as was possible.
Is it possible to create a loop using code to play a song on a webpage? Or does the while statement have to produce numbers like 1, 2, 3? I don't really understand what types of things I am allowed to use when creating a loop.
I just thought this might be useful - short little pre-loading of images on webpage. Code: <body onload="preImages()"> <script> function preImages(){ if (document.images){ aImgSrc = new Array("image1","image2","image3"); aImgLst = new Array (); for(counter in aImgSrc){ aImgLst[counter] = new Image(); aImgLst[counter].src = "images/" + aImgSrc[counter] + ".jpg"; }}} </script>
I have a question about hotspots in JavaScript. I'm trying to make a web page with two images. I would like to have Image 1 consist of five hotspots, each of which would change Image 2 when it is moused over. Basically, Image 1 would be divided into five small pictures, and when the user placed their mouse over one of the small pictures, Image 2 would change to match it. Is it possible to do this with hotspots? I could convert Image 1 into five different images and stack them, but it would be simpler to do it this way if possible.
Am using jquery and javascript to load images.Everthing is working fine, but I would like the user to be taken to a webpage for each of the images below.
Code: function PreloadImg(){ $.ImagePreload("/images/slash2.jpg");
I'm building a website which uses javascript to cycle through and fade images in the header portion of each web page. The javascipt os located in an external file and called via the master page. Here is the code in the content.js file which specifies where the images are located: // create array of images var CyclingImages = new Array("header/images/tankimage1.gif", "header/images/tankimage2.gif", "header/images/tankimage3.gif", "header/images/tankimage4.gif")
Here is the code in the master page which finds the javascript: <script language="javascript" src="<%= Page.ResolveUrl("~/content/content.js") %>" type="text/javascript"></script>
Here is the function call in the masterpage to fade and cycle the images: <body onload="FadeAndCycleImages()">
Here is the code in the masterpage which references the cycling images: <span class="fadingimages"> <img src="<%= Page.ResolveUrl("header/images/tankimage1.gif") %>" width="142" height="124" title="" alt="" name="cyclingimage" /> </span>
Each webpage loads the masterpage. If the webpage is located at the root of the project, the cycle and fade functionality works great. When I start to place some of the webpages in separate folders - which I need to do - the cycling and fading functionality breaks down, meaning the images cannot be found. The image place holder is there with the standard red "x" in the upper left. I have done a lot of research and tried many approaches to try to resolve this issue, but with no success. The root of the problem seems to lie in the fact that I cannot apply Page.ResolveUrl within the content.js file.
Let's say I have a Javascript function that loops over and over. In that function i have it alternating images on a button this way:
if(var==0){ var myHTML = "<input type='button' style='background-image: url(grnbutt.jpg);etc. etc.'>"; var outq = document.getElementById("qbutt"); outq.innerHTML = myHTML; } else{ var myHTML = "<input type='button' style='background-image: url(grnbuttdark.jpg);etc. etc.'>"; var outq = document.getElementById("qbutt"); outq.innerHTML = myHTML; }
This works great using Firefox, and works with Internet Explorer also EXCEPT if its set to "Check for newer versions of stored pages: Every visit to the page". With that setting, IE will download those 2 images from the server every single time through the loop. So then I tried putting both images on the same jpg and then moving the image:
if(var==0){ var elem = document.getElementById("grn"); elem.style.backgroundPosition = "-100px 0"; } else{ var elem = document.getElementById("grn"); elem.style.backgroundPosition = "center"; }
This also works, but also, constantly downloads new images when using IE with the above setting. Microsoft calls this a "feature". They then offer a fix for this "feature" that... doesn't work. Preloading doesn't work. Loading the 2 images in a <divset to invisible doesn't work. I've tried suggestions of creating php files that tell the browser that the images don't expire for years. That didn't work for me. Many people have also suggested that there is no way around it... it can't be fixed until Microsoft fixes it.
So, is there any javascript way to loop 2 images on a button, without Internet Explorer constantly downloading those 2 images over and over, when its set to "Check for newer versions of stored pages: Every visit to the page"?
i am making a gallery and i was advised by philip m to preload my images before hand, so that the gallery runs smooth. i have done so but in a different way to what ive seen on some of the other posts on this forum and i was just wondering if this was practical javascript or am i over doing it.bascially, the images are external hrefs loaded into place holders.the external hrefs are stored as strings in an array.
so the loop runs for however many image hrefs are in the array.so the first iteration of the loop, an image is created and is given the href of whateever value the loop is of the array.then for each iteration of the loop, the var img, is overwritten with the next href in the array.so technically, iam not creating as many images as there are in the array, i am just creating 1 then overwriting it, but still loading the image data in to the browser cache.
I am trying to do the following: I have written a simple programm that loops through an array of images when the user clicks a button. I have used a for loop to do this. The program works fine, however when I get to the end of the array, the condition created in the for loop is "true" therefore the button no longer changes the image. How do I start the loop again to create an infinite loop (i.e. every time the button is clicked, the image will change)?The script I have written is as follows:
var mySpheres=new Array("sphere.gif","sphere2.gif"); function changeSphere(){ mySphere=document.getElementById("sphere");[code]....
I'm designing a page to fade multiple images (three) in and out over a set period of time (one minute, say). The code I have works as follows:
I define an array and fill it with the div objects I want to fade in and out. I have some simple tags (2 for opaque, 1 for fading in, -1 for fading out, etc.) that I set to show the state of the object.
First I check if the object is opaque, and if so set it to fade along with a time;
Or if it's transparent I give it a 1 in 10 chance of fading in during this iteration. If it's currently fading in or out I check to make sure it's on track and change the opacity of the div accordingly.
Originally, I had the function call back to itself using setTimeout after the loop had gone through all the divs and changed their opacities appropriately. This caused an out of memory error (though, strangely, if I had any alerts in the function it didn't give me the error).
So the version below has the code in a while loop to let it run for 20 seconds - this gives me the "a script...run slowly, do you want to continue the script?" message.
So I have several questions:
1) First and foremost, why is my function causing out of memory/run slowly errors and what is the best way to fix that?
2) Is there a better way to code this effect (final result will be six lights fading in and out for a minute or so).
3)I'm not an experienced programmer, so any bad practices, ways to streamline, no no's, etc. that you see, please point out.
I've only posted the script here - the page simple consists of three divs (id's grad0, grad1, grad2) and a call to the function copied here.
As it is known from the title, I'm building a web page running continuous slideshow of images, like watching a video. I wrote the header part below:
Quote:
<script language="javascript" type="text/javascript"> var slideimages = new Array() function slideshowimages() {
[Code]....
Here, the biggest problem is, when the page is loaded there are still coming images saved from a capture device. So, my images from the captures device can not be loaded to my web page. I need to pass these images directly to the web page as real-time video taken directly to the web page.
It launches in IE and give the user instructions, then at the click of a button, launches my setup.exe. I want my webpage to launch setup.exe then go to another webpage on my CD, congratulations.html, which says "installation is complete etc". Here's what I am trying to do through JAvascript. It doesn't work. Should the first instruction be flushed in order for the 2nd one to work?
I want to use the values of text boxes on my HTML webpage to create a webpage URL (like below):
<script type="text/javascript">
My text boxes are as follows:
Now this all works and the result webpage URL prints to id='ID1', but the big question is how do I use this resulting URL in another Javascript section as the src="?
I am trying to display a webpage from another domain and tried to access its elements and I am facing issues with this.
I tried using "iframes" and am facing cross domain issues.
All that I want to do is, set and get the attributes of the elements of the webpage from the other domain (eg: set text field value, get dropdown box values, click button etc)
Is there a way to get this job done?
I thought of browser addons however it will be a browser specific solution.
Could anyone know the script code for a WEBPAGE ON TOP OF A WEBPAGE? The site was not working anymore, so I can't tell you the link. This is what I saw, When I visited the site (Mainpage) There's just a Welcome Image that shows CLICK HERE TO ENTER. After clicking the link, a loading faded icon appears on top of Welcome Image covering that Welcome Image with Webpages, it's like popping to the center of the page. I don't know if someone of you could understand me. It's like Page on TOP of another Webpage without leaving the 1st page.
I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together.
What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array.
What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created.
I'm looking to send a loop variable (i) to a function inside the loop, but I can't seem to get it to use the value I want, it keeps making it a reference of i and therefore the function is always called using the last value of i rather than the one it was set with.
So if i have 5 Tabs then Tab 1, when clicked, should call DefaultTabClick(0) and so on rather than always using 4 for any of the tabs.
