I need some help on how to reposition a layer depending on the position of an image? I know this should be somewhere in the forum, but I searched without success.
I mean like this:
<body onload="movemylayer()">
<img src="1.gif" id="myimage">
<div id="mylayer"></div>
</body>
...And when the page is loaded the layer moves infront of the image.
I'm having some trouble with absolute positioning:
I have a main div, with some nested divs inside, one of which is "position:absolute". When a user hits a button, a message will appear at the top of the div (by using "myDiv.style.visibility = 'block'"), which pushes all other sections, relative or absolute, down appropriately. This is what i want.
However when the message div is clear (using "myDiv.style.visibility = 'none'"), all the relative divs go back to their original position, but the absolute div stays at its pushed down position.
ive tried several complicated schemes to correct this, including setting the absolute sections top to certain values, and it doesn't want to move back.
Does anyone know a solution to this problem, or of a way to "refresh" a divs position?
I am simply trying to alert the left position of a css layer.
Javascript:
var Element = document.getElementById('box');
alert(Element.style.left);
CSS
#box {position:absolute;
left:150px;
top:150px;
background-color:blue;
height:100;
width:100;}
HTML
<div id="box">
</div>
The problem is the alert is blank and I can't understand why.
I am trying to make a layer that mimics a particular cell in a table (please dont ask me why, its complicated). I have created the layer so that its dimensions exactly match the table cell in question. Now I want to create a function that sets the top and left position of the layer to exactly match the top and left position of the cell in question. I have already had a try myself, but for the life of me can't quite figure it out.
I tried giving the cell in question and 'id' tag (id="centerCol") and then referencing the left and top values of the object. See the following code:
document.getElementById('layerHeader').style.left = document.getElementById('centerCol').style.left;
Any suggestions on what I am doing wrong?
I have a div with opacity 0.44 and a picture inside it. When i activate mouse events, this picture (with position absolute ) floats to top. This effect is seen only in Opera. Is there a workaround for this?

Layer writing in Netscape. This is pretty straightforward >> However I'm trying to write to a <div> layer within a <div> layer.
My div:

</div>
I'm trying to write to "aight"
How should my code look?
I've been looking all over the place in order to find a script like they use on Foliostars, where you see a sliding semi-transparant text layer over a thumbnail image when you hover. how to achieve this using JS or an Ajax framework (preferably JQuery)?
View 2 Replies View RelatedWhat I'm designing is a page with many layers each containing an image, these layers are about 300x200px in size and are spread over a large space on the page, which will force the page to be about 5000x5000px in size. The user will then have to scroll around the page both horizontally and vertically in order to see these layers containing images.
However, if all of these layers with images are loaded when the user enters the page, the used bandwidth will be huge. So what I'm thinking is figuring out a way to only load the images/layers that are in the users view, so that when the user scrolls to a new spot on the page, the images in that area are loaded, but not before.
How can I achieve this?
I have a notion that I might need a function to check which x&y position the user is at, and then set the content of a layer when the user's view 'contains' that layer. Is this a good way to proceed, and which functions should I look at?
I've tried the tutorials but I have never worked well with those -- I've always found it easier to actually be working with someone. But anyway. Basically, I need something sort of like this [URL] -- you click the thumbnail and the image appears in that predetermined spot. One thing, though: the images have to layer over each other. Like, you click image A, and it appears in the spot. You click image B, and it appears on top of image A. It'd be even better if when you clicked Image A it appeared and then you clicked image A again and it disappeared, but I'm going to try to start small.
I've gone through the tutorials and have a sort of ish understanding about what some of the parts of the codes do, and I've been told I'm a fast-ish learner, so I think I'll catch the hang of this quick.
How can I open a zoom image layer on mouse over, similar to [url].... Screen shot attached.

The html page is as follows:
Many common software systems, JavaScript has a history of security problems. Many of these problems could allow a person with malevolent intent to steal sensitive information from a visitor. The number and type of such holes in security vary among browsers and operating system versions. Most JavaScript security holes have been caught and fixed, but new ones are being discovered all the time. For a list of current security holes check out your browser's and operating system's Web pages. As a Web site author, it is your responsibility to keep up-to-date on the current status of known security holes in the applications you create.
Signing Scripts. In Chapter 11, I explained that JavaScript does not provide the ability to directly access files on the client computer. This can be a very large hurdle to overcome if you're trying to upload a file to a server from the client computer. Fortunately, file uploading is one of many functional enhancements that signed scripts provide. Signed scripts are specially packaged scripts that have been verified and signed to be correct and non-threatening. These scripts have additional rights on the client computer that allow a programmer to do many things that he wouldn't otherwise be able to.
With the introduction of Netscape 4.0, a new security model was put in place that would allow digitally signed scripts to bypass some of the restrictions that had previously been placed on them. A signed script can request expanded privileges from the visitor and, with the visitor's permission, gain access to restricted data. A signed script requests these additional permissions through LiveConnect, which allows your JavaScript code to communicate with the Java Capabilities API. The security model allows JavaScript to access certain classes in Java in order to extend its functionality while still maintaining tight security for the client.
A digital signature is a fingerprint of the original programmer, and it allows the security model of the browser to detect where (or from whom) it originated. A script signer can be a person or an organization. By signing a script, you acknowledge yourself as the author and accept responsibility for the program's actions. A signed script contains a cryptographic checksum, which is just a special value that ensures the signed script has not been changed. When a digital signature is detected, you are assured that the code has not been tampered with since the programmer signed it.
Once you finish writing a script, you can use the Netscape Signing Tool to digitally sign it. Signing a script does the following:
Unambiguously assigns ownership of the script to a person or organization.
Allows an HTML page to use multiple signed scripts.
Places the signed script into a Java Archive (JAR) file.
Places the source of the script in the JAR file.
Once a user confirms the origin of the script and is assured that it has not been tampered with since its signing, he or she can then decide whether to grant the privileges requested by the script based on the validated identity of the certificate owner and validated integrity of the script.

Does anyone here know of the javascript I'd use in a situation where I didn't want to display a certain image when the client is using IE6? I'm fine with displaying it in IE7 and Firefox, but don't want it displayed in IE6. The image is a PNG with a transparent background.

Is there a script that displays an image depending on the domain?
View 2 Replies View RelatedI want to make a script that composes an image depending on several variables. The image is composed of a base piece of clothing (e.g. t-shirt) on which an image and text can be placed. The color of the piece of clothing; the location of the image, the image itself and the text are variable. Also the font of the text can change. Is there a base script I can use? Or is there a small script that handles a piece of the desired functionality?

I was wondering if there is a way to use Jquery to reduce the amount of images I use on my company website as well as resize them depending on the page they're displayed on. It's just that I feel that's it's very tedious creating 5 or 6 formats for each campaign each with it's own dimensions depending on the page and unfortunately my company doesn't want to implement a Backoffice fed site, which means I have to do it all manually.
View 3 Replies View RelatedI have three DIVs that are stacked vertically. Each section (div) I want to be able to 'collapse' or minimize, and when that happens, for instance when the first div is 'minimized' the second two divs shift their left/top positions to fill the space. Right now, I'm doing this automatically, by creating a javascript function and changing the top/left and "height" properties manually.

The code below lets a user select a drop down option and a picture changes depending on the selection. I am trying to make it so when you select an option on the dropdown the picture shows up in the center of the screen and in the background behind the text. Here is the code.

<head>
<style type='text/css'>
#txt {background-repeat:no-repeat;width:200px;height:200px;}

After a javascript-generated post event (this is a post, not ajax
messaging) the current screen has to be redrawn. But on *long forms*
(longer than a single screen) then the current screen positioning
is lost, and the current form ends up redrawn, with a different
vertical positioning--after the post event.
However, If I sent the x,y mouse position as post parameters,
and if the current widget (that generated the post) had
a well-known anchor tag name, would there be a way
to combine that much information, after the post, in order to redraw
the form close to it's original vertical positioning?
How?

I use $().load() to place an HTML snippet from the server into a dialog box which i then need to position relative to the size of the element which has just had the HTML loaded into it. When the main HTML page DOM is ready, I hide() the dialog box, and then use fadeIn() to show with various click() events. I have managed to position the dialog box in the centre of the screen given that there is no content loaded.
However, it seems that when I load the new content into the dialog box the new dimensions aren't taken into account untill the next time load() is called.
Is there a way to get the new dimensions of the element before the dialog is shown in order to position it centre screen?
Here is my code:
function showDialogBox(sender) {
var width = $(document).width();
var height = $(document).height();
