Swapping CSS Background Images?
Apr 15, 2010
I've got a JavaScript / CSS question if anyone has a spare minute and the interest? I've got a page with a background image set by CSS. I want to use a Javascript function to change that image with a link click. Here's a snippet from my HTML:
HTML Code:
<body>
<script type="text/javascript" src="changeBGimage.js"></script>
<style type="text/css">
body {background: url('red.jpg') no-repeat}
</style>
[Code]...
Would you be able to tell me how I would structure that function?

I know this is sorta reposting but I want to simplify the issue a bit. Take the following script:
function replacemain(s){
var x = document.images['MainImage'];
var y = document.images[s];
var pictemp = x.src;
x.src = y.src;
y.src = pictemp;
}
All I want to do is replace the image specified as "s" with the MainImage. Actually swap them so that each execution of the function will swapp and reswap the images without loosing anything. This generally works, however, on a couple IE6 browsers it causes blank images to swap in....

I've created a javascript version of the classic game SOKOBAN. Basically what happens is you move the man around the "warehouse" and he must push the boxes into the target area. Copy the code and try it yourself to see what I have so far (note-he can't move the boxes yet).
My question is: Right now, my map consists of solid color blocks. What I WANT them to be is image files (for example: box.png, wall.png, floor.png) to add a little versatility and life to the map. I am not sure how to make this switch though. I suspect I make the change somewhere in the tile array in the initialize function, but I am not sure what..
Also, how can I get the boxes to actually MOVE? I.e. when my man pushes them, they move around in the direction he pushes?

I need to create a page containing five image tags, two buttons, a <select> and a <textarea>. The images tags will each contain a picture of one of six possible outcomes for the dice portraying the numbers one through six..
The first button: When the user clicks on the button, all dice are rolled once. For each die when rolled, the src of its image tag is replaced with a random one of six possible pictures -- each picture being chosen with equal probability (1/6).... I HAVE THIS DONE
The select: The user may select any of the numbers one through six. Whenever a picture is clicked upon, then that die takes on the value shown inside the <select> THIS IS WHAT I NEED HELP WITH
The textarea: Results of the dice rolls should be kept as a running log (a cumulative history) in a textarea at the bottom of the page. With each roll (initiated by the click of the button), we should be able to see the complete history of all current and previous dice rolls. You need not consider changes brought about clicks on individual dice in conjunction with the <select>....I HAVE THIS DONE
The second button: A button below the textarea, should allow the user to obtain a report (overwriting the current contents of the log in the textarea) which tabulates the frequency of each of the six outcomes plotted separately for each of the dice. The frequency tabulation should show how often each die was rolled, as consistent with the data stored in the log..

I have an image inside of a div that I'd like to swap every time the function is triggered. I was able to attach first image through this: Code JavaScript: this.titlecontainer.appendChild(document.createElement('img')).src = 'images/picture' + padded_index + '-t.png';
This indeed does add another image on each function iteration but as the code suggests, it actually APPENDS additional images. Instead, I'd like to SWAP the existing image for a new one. My guess is to remove what's currently loaded inside the div prior to appending another one. What would the line preceding the above have to look like to accomplish removing of the content?

What I would like to do is enable swapping between the black images? I would like to drag and drop to another image and that image will fill up the dragged earlier image position?

I've run into a problem with swapping images for site navigation.The "hover" part works just fine, but the problem lies within the click part. When the user clicks the first thing that happens is to reset all of the images for all of the links, and then set the hover image for the link that was clicked. However it seems that after resetting all of the images 'src' attributes, the code for setting the link that was clicked either doesn't execute, or executes before the reset.

working on a feature that displays 3 news stories. The stories are accessed by 3 buttons on the top, sort of like a tab-style navigation. The catch is that all 3 stories are on the same html page, the "navigation" is just showing/hiding content based on Java, CSS & div's. Where I'm stuck is creating On/Off state for the tab buttons. What I'd like to do is:
Click button 1, buttons 2 & 3 turn off.
Click button 2, buttons 1 & 3 turn off.
Click button 3, buttons 1 & 2 turn off.
Naturally I have separate version of each button for the on/off state, I'm just not sure how to initiate the swap...Do I set a JS variable on the onclick? Or is it just a function?

Newbie here. I am seeking to swap out three images when rolling over one. Cursor hovers over one image - three new images, in different locations, are seen on screen. When cursor moves away - the images revert to "normal" state.
Image 1 - thumbnail - bottom right of screen
When rolling over Image 1, three images change:
Image 1 - to shaded version of the thumbnail
Image 2 - main image center of screen
Image 3 - text box image top right of screen

I am trying to create a menu that would look and act like this image illustrates: [URL] Essentially the three boxes slide down when rolled over and menu items appear in the portion that has slid down.So far, I have figured out how to make an image slide using jQuery: [URL]

I'm putting together a portfolio site and I'd like to use high-res images that take up most of the screen to show different works. There
would be a menu bar with links to each work, where a click on that work's link would change the background by doing a standard "dissolve"
effect.I have seen many different plugins for "rotating" images and changing background colors at the click of a button. Is there a method
specifically for this purpose? As an alternative to altering the background-image of the body itself,I would be willing to use a properly sized div (or div's) to achieve this effect.

I've prepared the following page: [url]
But I would prefer the background images to fade in and out rather than change abruptly. I've spent hours searching for appropriate code, but have met a dead end so far.
Incidentally, I presume that the delay before the first background image appears is because of all the images pre-loading. Can anyone suggest a way to immediately display the first image?

I've got a Javascript which changes the background image of the body by rotating other images. What I want is the script to change the background to a specific div and not of the whole body section. Since I'm not an expert in Javascript I have Googled a lot but couldn't work it out till now. In other words that I want is to alter/change in the script the line "...document.body.background=processed [abc].src.." in a way and add ... so that this script works for a specific div and not only for the whole webpage...
<script language="Javascript">
var bgimage=new Array()
bgimage[0]="image1.png"[code]....

I have a page where there are 4 images that are loaded as a div background via css file.
When I try to use javascript to preload them it just does not look like its pre loading them.
I tried doing the following but the images don't pre loaded. They appear one after another.
Code:
<SCRIPT language="JavaScript">
<!--
pic1= new Image(100,25);
pic1.src="http://someplace.com/image1.gif";
//-->
</SCRIPT>

I've worked for a while to get a table background image to automatically rotate using JS, and it's working well now. However, it's quite choppy. Any way to make the images crossfade to smooth it out?

I am looking for some recommendations for JS/HTML code that will
allow me to generate drop down menus, sort of like the ones here
Code:
where you can see the drop down menus if you roll over "Flights",
"Hotels" and so on. The only thing I want to do differently with this
is that I want to put a repeating background image behind the entire
menu that drops down, and not necessarily just each item. So, in the
above example, if you rolled over Flights, I'd like a background
graphic to span all the menu items -- "Search Flights", "Top Deals",
"Web Fares", "Low Fare Alert", and "Last Minute Packages."

I'm using a double background image for a site - basically two containers around everything, one with a gif with patches of different colour, and above it a semi-opaque png with a very faint texture. I'm doing it this way as it makes for much faster loading than one jpg with the image and texture combined.
The only problem is that you see the gif load first, then the texture goes over it. Is there any way, perhaps with JS, to hide these background images until they're both fully loaded, then display them together?

I have a JavaScript routine that runs on a timer and updates the position of a
background image using the CSS background-position property. In Internet
Explorer, it changes the mouse pointer to an hourglass when it refreshes the
screen, and this is really annoying since it happens on the timer, about every
100 milliseconds or so. Is there anything I can do about this?

My client wants a series of 4 background images that cycle (probably fade), and each time a new image appears, they need text to slide in from either the right or left, depending on the image.I've done the fading background image part quite often, but have never tied another action to the new image loading.
<picture 1, fades in><text for picture 1, slides in from right>
<picture 2, fades in><text for picture 2, slides in from left>
<picture 3, fades in><text for picture 3, slides in from right>
<picture 4, fades in><text for picture 4, slides in from left>
I've seen a lot of tutorials for the two things separately, but not for the two combined. And I'm the first to say I'm a newbie to jQuery and relative newbie to Javascript. So I'm not sure how to go about even knowing if this is do-able.

Code within my <HEAD> Tags;
<script language="JavaScript">
<!-- Activate cloaking device
var randnum = Math.random();[code]....
Now, this works fine with every manual refresh of the page and I can obviously get it to work with a <META> refresh, but I would like to do achieve this without resorting to this crude method.Note that I have additional code to stretch the image to the client browser resolution.I found this topic which look svery similar to what I want but doesn't have any code for the background image scaling ... http:[url]....
