I have a page with many divs and style, with my div buried somewhere inside.
I am trying to have a button that automatically makes my div, that includes a video player, resize and capture the whole browser.
In order to do that I am trying to get the current position of the div and then position it relatively so that it'll get to the top-left corner so I could then use document.body.clientHeight/clientWidth.
Can't get this to work.
I tried the approach of moving my div to the first div and then resizing however this messes up the flash player.
Any ideas? any different approaches?
Thanks,
Guy
Use one of the lightbox clones that can handle DIVs. They usually copy the DIV in question into their own view DIV, which helps with positioning issues and you don't have to do anything to the buried div.
I find Multi-Faceted lightbox to be very easy for customizations:

but there are lots of others around as well.
Why relative?
You should rather use fixed instead of relative. Then set positon to 0,0 and width and height to 100%.
Simple js can do this.
On click, just set the div's style to 'fixed', and position 0,0. Like:
var theDiv = document.getElementById('yourDivsId');
theDiv.style.position = 'fixed';
theDiv.style.top = 0;
theDiv.style.left = 0;
This should do the trick:
<div style="position:absolute;top:0;left:0;width:100%;height:100%">
some content here
</div>

I am trying to get the visible height of a div and I can't find the way to do it.
http://jsfiddle.net/MVupa/1/
Even the library fracs:

Does not seem to give me the right number:

Any ideas?
(End goal is to adjust an element max-height dynamically, depending on the window height.)
this is what i came up with: jsFiddle
$('.height').text($('.inner').height())
$('.scrollHeight').text($('.inner')[0].scrollHeight)
$('.inner').height($('.outer').height());
$('.visibleHeight').text($('.inner').height());
and you can set it to a $(window)resize(); function.
I have a set of divs with position = absolute, and they can be positioned across the screen.
If the content of any div doesn't fit on the screen, the browser wraps the text into multiple lines and attempt to fit inside the window.
However, I dont want the browser to do that, It should instead hide the content.

Edit:
you may think of it as a div on a page with absolute positioning. and
1) the user can drag the div around
2) user can manually change the width of the div( there is a stretch box widget, which the user can use)..
So the problem is when the user is dragging the div around near the edges of the screen, the text should hide and not wrap if it goes out of the window. Hope this explains better
As shown in the example, block 2 shown is what I want.
So, lets say the width of the div is 100px, and the left position of the CSS style is (screen width - 50), then the rest of the text should hide.
Solution 1: white-space:nowrap. Cant use this, since this is a flexible width UI where user can change the width of the div if they want.
Solution 2: If I set the width of the div, explicitly to a number, it works fine.
But not a optimal solution, as then here I will always have to calculate the width for all divs at the time of rendering.
Is there a more optimal solution, which can make the browser not try to fit the text into the screen.
Hard to tell what you're asking. But I think you can use
{
height: 1.2em;
overflow: hidden;
}
To hide the content that is longer than the one line you support

If you put them all inside a huge (e.g. 5k px * 5k px absolute positioned div you should see the expected effect: http://jsbin.com/welcome/35862/edit
Is this what you want? (second item)
I wrapped the inner text in a very long div and applied overflow:hidden to it's parent.
I am not sure the exact use case of the widget so I am not 100% sure on what it can have and not have. I have an idea, maybe it will be useful - setting width to a % might help, something like this
.block2{
left: 50%;
top: 100px;
width: 100%;
}
you can set this in the css to avoid calculation with js, but like I said I am not sure of how this is used so this might not work but it might give you some ideas
I have a grid of elements (3 x 3) formation which toggle visibility on hover, easy.
However my next step is to grow said elements to fill their container when hovered upon, I'm assuming I would need to get current (x,y) values and then grow this to the (x,y) values of the parent container and use css positioning, however every approach I take is hitting a brick wall. I have a fiddle here which demonstrates the layout / intended functionality - http://jsfiddle.net/u2w7J/
Any help would be gratefully appreciated!
The way your HTML is set up currently, this is kind of hard to accomplish while having it look smooth. A first try is to use the .toggleClass function and toggle "box" and "miniBox" for the hovered element. See http://jsfiddle.net/u2w7J/6/ for a demo.
Positioning is harder since the miniBoxes are not positioned absolutely. Hence, adding animation is causing weird results (see above demo).
I would suggest to have the miniBoxes positioned absolutely. When hovering, get the parents div left and top values and animate the miniBox using these values. Additionally, raise z-index during or before the animation to prevent other miniBoxes being visible.
I have a div of fixed dimensions into which some JavaScript functions will be placing text over time. When the amount of text exceeds the height of the box, a scrollbar appears thanks to overflow:scroll.
The new problem is that the view into the div stays at the same place as more content appears. What I mean to say is that it stays scrolled wherever it is as more content appears beneath, hidden unless you manually scroll down. I want to make it automatically scroll to the bottom as new content appears so that the user naturally sees what appeared most recently instead of what's oldest.
Ideas?
You can use scrollTop method after each text addition:
$("div").scrollTop($("div").children().height());
Use inner block to get the true height.
DEMO: http://jsfiddle.net/eyY5k/1/
I found this approach to work for my needs:
var realHeight = $("#history")[0].scrollHeight;
$("#history").scrollTop(realHeight);
Do note this uses jquery.
I have a 700x300 background repeating seamlessly inside of the main content-div. Now I'd like to attach a div at the bottom of the content-div, containing a different background image that isn't repeatable, connecting seamlessly with the repeatable background above it. Essentially, the non-repeatable image will look like the end piece of the repeatable image.
Due to the nature of the pattern, unless the full 300px height of the background image is visible in the last repeat of the content-div's backround, the background in the div below won't seamlessly connect. Basically, I need the content div's height to be a multiple of 300px under all circumstances. What's a good approach to this sort of problem?
I've tried resizing the content-div on loading the page, but this only works as long as the content div doesn't contain any resizing, dynamic content, which is not my case:
function adjustContentHeight()
{
// Setting content div's height to nearest upper multiple of column backgrounds height,
// forcing it not to be cut-off when repeated.
var contentBgHeight = 300;
var contentHeight = $("#content").height();
var adjustedHeight = Math.ceil(contentHeight / contentBgHeight);
$("#content").height(adjustedHeight * contentBgHeight);
}
$(document).ready(adjustContentHeight);
What I'm looking for there is a way to respond to a div resizing event, but there doesn't seem to be such a thing. Also, please assume I have no access to the JS controlling the resizing of content in the content-div, though this is potentially a way of solving the problem.
Another potential solution I was thinking off was to offset the background image in the bottom div by a certain amount depending on the height of the content-div. Again, the missing piece seems to be the ability to respond to a resize event.
Another approach is to calculate the background-position style for the bottom and top DIVs based on the size of the content DIV. You can use negative positions to align the bottom of one to the top of another.
Yet another approach is to use a layered DIV approach in which the top, content and bottom are all children of a parent DIV that contains the background.
The benefit of these approaches is that it doesn't change the natural rendering of the content DIV simply for managing the background.
Example: http://bin.googlecode.com/svn/trunk/css/repeating-bg-content.html
Could setting background-position: fixed in your css help? Then your bottom div could move, but its background image would remain fixed in relation to the top of the page. As more of your repeating image was revealed, so more of your bottom image would be hidden.
This would comes under the heading of "offset the background image in the bottom div by a certain amount depending on the height of the content-div", rather than "the content div's height to be a multiple of 300px under all circumstances".
You could try adding an event listener to the div:
var div = document.getElementById("content");
div.addEventListener("resize", adjustContentHeight, false);
If nothing needs to match up at the top, position the repeating image at the bottom of the div (so the overflow will spill over the top). Like this:
div#repeating { background: transparent url('/path/to/image') repeat left bottom; }
