I'm working on a script that fades in and out both an image and a div I have set behind the image when you hover over the image. I'm having two problems:
The fades on the image and div don't seem to move at the same speed even though I have them set to.
I can't figure out how to get the div's to only show for the image you hover over. If I could type ("this" div.info) as an object, it would work fine. Is there a way to do that?
I can't get $(".info",this), $(this).find(".info"), or $(".info", $(this).closest("li")) to work.
Result: I have found the solution. I was able to get it to work by using lthibodeaux's suggestion and using $(".info", $(this).closest("li")) as the object and making all the functions .fadeTo go here for the result:

Edit:
I found out the image and the div animations really were moving at the same speed, just the image only had it's z-index set on hover, so if you took your mouse off the image while the animation was running, it would appear to move at a different speed than the div when really the image was behind the div, it only appeared to be moving at different speeds because when the div became invisible you could see the image behind it but when it became opaque, the image was gone (making you think the image became invisible when really the div was in front of the image). This was easily fixed by moving the the z-index property from ul.columns li:hover img to ul.columns li img.
The div only had a border around it while you hovered over it. This was easily fixed by changing the border properties from ul.columns li:hover .info to ul.columns li .info
Check out the final version here: http://jsfiddle.net/tV9Bw/
This is the final version because I can no longer find any problems with any of the code; everything is optimized, there are no glitches, and it looks great.
Thanks to everyone who answered and to Yi Jiang for editing this post with better formatting. I'm new to this site so I wasn't sure how to properly format my question.
and a Huge thanks to artyom.stv for fixing the last glitch in the script that I didn't know how to fix.
You've got the general idea. One thing you should know about a selector is that you are able to define a second argument as the scope of the selector, i.e.
$("selectorString", scopeObject)
In your case, make the second argument $(this).closest("li"). It will find the list item containing your image and select .info descendants of that container:
$(".info", $(this).closest("li")).fadeIn(1000);
Change $(".info") to $(this).find(".info") and all will be sweet.
Yes you can use something like $(this).find(".info") as mentioned by Bundy
but as The jQuery constructor accepts a 2nd parameter which can be used to override the context of the selection.
You can also do something like this:
$(".info",this)

I have a wordpress theme that i'm building but i've hit a snag with some code and can't seem to get my div to expand correctly. I've tried clearing the floats at different positions, i've tried overflow: hidden, but nothing seems to work.
What i'm trying to do is have the content slide in from either side based on what header you click. The content is based on a wordpress post for each link. So the client can easilly edit it to any size.
Because of this it isn't viable to use pixels in the sizing of it. And i know that absolute positioning means that pixels are very nearly the only option.
I've messed with everything i can think of in firebug and just cannot get it to expand.
You'll find the site here: http://tinyurl.com/okd5wnf
However i couldn't get this to work either. Maybe that'll give you a clue as to what might be wrong.
I know it's a long winded post, and i apologise. If i have time later, i should be able to make a jsfiddle. However time is short at the moment.
Any help would be appreciated. Thank you very much.
Your problems stems from setting the <div class="box"></div>'s position property to absolute. Give the parent element(<div id="body-wrapper"></div>) overflow-x:hidden; to hide children that are not being displayed, and then use negative margins to position child elements within the viewport (the parent element). This is basically how most sliders work.
Remove position absolute from box class. please also mention what desired layout you need for content. we will suggest you classes for that.
Romove position:absolute from div.box
I guess that's all.
What I'm trying to do is something like you see at http://www.nejm.org/doi/full/10.1056/NEJMimc1109704. (Click Play and go to page 5 - the interactive physical exam.) I think they are doing this with Flash, but I'd like to use javascript/jQuery.
Basically there's an image that has multiple captions. The captions have arrows that point to different parts of the image, but that's not essential for me. When you click on different links, different captions appear.
Would I tackle this as an image map? I.e. create a map, and use jQuery to toggle different parts of the map? Is there a plug-in that does that? Google searches aren't helping me - but maybe I don't know what to look for. Any help will be appreciated.
I'm having the same problem and I found imageMapster. Check out
http://www.outsharked.com/imagemapster/default.aspx?demos.html#beatles
I think this is what you want to do. Just this solution today, haven't figured it out yet. Looks promising though. Otherwise check out qTip2

Maybe some adaptions let you/us do what we wanna do
Good luck! Keep u updated if I figured it out
Why would you need jQuery?
Anyway, put your main image down, and set its position to be fixed where you want it. You could even put it in a nice container div, just make sure all your caption divs are relative to the same parent. Then put fixed position divs of your caption images over it with a higher z-index in your css. Then place your caption images at the appropriate top and left positions until they are correct. Of course, use transparent PNGs.
All you need to do to toggle them is set the element's style.display to "none" or "inherit"
If you'll take a look at this:
http://jsfiddle.net/hunterscott/JYLVQ/
You'll notice that if you try to drag the image, you can see the helper move, but it won't leave the gallery box. I have a feeling this is a CSS thing, but I'm not sure where it is.
Edit: Sorry, I need to be more specific, since that fiddle is pretty watered down from the full project. Gallery-wrap has to be set to overflow:hidden because it is an image carousel that shows 5 images at a time, and the rest are hidden. The user clicks arrows to advance through them. If I make gallery-wrap visible, then the images that shouldn't be seen are seen stacked below the first 5.
#gallery-wrap
is the culprit, it has overflow:hidden; set.
EDIT: ah, thanks for the clarification. Does this help?
I have 4 images stacked on top of each other, see below:
I'm trying to achieve two things:
When the mouse is over an image that is in the background, that
image should come to the foreground with a fading effect. There is
also different text below each image, that text should come to the
foreground. (no fading needed there)
The result should be like this:
Every 10-15 seconds (without user input), the next image on the right should fade in
automatically.
Technically, I thought about putting each image and text into a separate div, and playing with the z-order. The fading effect could maybe be achieved using jquery, but I've not used that before, unfortunately.
Any example code, specific help or pointers is greatly appreciated.
Thanks!
Although it's impossible to control the fade of an element through his z-index
we can always trick what our eyes see.
DEMO GALLERY
To achieve that we can do:
Insert into our gallery a DIV element that will grab the src attribute of the current image and set it as his background image
hide the current image, position the DIV on this image .position()
fade our DIV in/out
reset image visibility
Let me know if you have some issues, I can comment my code to make clearer the steps I used.
Happy coding
Take a look at this plugin. Just explore it, this has got 100s of different effects which you might like to use in your case.

I am trying to generate a html page with css that works as an image preview kind of thing. An example of this is here:
http://www.nomorepasting.com/getpaste.php?pasteid=22463
however this approach has several drawbacks. One of which is the text must always be smaller than the images. I tried using a different attempt here:
http://www.nomorepasting.com/getpaste.php?pasteid=22464
But could not get it to work. Would someone please be able to show me how to modify the code at the second link to work as the first, or to suggest an overall better method?
The error in second one is you haven't specified the height attribute.
Try the following, it worked for me.
.class1{
color:#000;
background-image:url('images/2.jpg');height:1000px;
}
The reason you are not able to see the back ground image is, since there is nothing inside the div, and the height is not specified the height is 0.
Try putting a few elements in the div and you will see that the image is being displayed.
