Get The UL Offset Beyond The Viewport?
Mar 27, 2011
I have developed a vertical accordion menu and all is great except for the fact that some of the submenus are long and run beyond the bottom of the viewport. I need to detect the position of the UL, find out how many pixels are below the page fold, and lift the UL up by that many pixels so the UL does not go below the fold. The UL in question is positioned absolutely inside of a relatively positioned parent so I can easily use a negative top position to lift the UL but how do I get the number of pixels that the UL descends below the page fold?

THIS IS NOT HOMEWORK this image:http://three-dog.homelinux.com/images/offsets.jpgThe image represents an "entire" web page and the bright part the area currently scrolled into by the web browser.I can get the client's screen SIZE, but I don't know how to figure how many pixels down into a page the browser happens to be.To clarify, the distance shown as a question mark would be "zero" if the browser were scrolled all the way to the top of the page and some positive number as the browser scrolls down.Is there any way for me to get this number (in Javascript).What I need it for is to position a pop-up window centered left-to-right and 1/3-2/3 top to bottom on the screen REGARDLESS of where in the page the browser is scrolled.

I'm using a script to display a floating menu. I don't know how to set an offset for the footer so that it does not go all the way to the bottom. I'd like a 100px margin to the bottom of the screen. Here's my code:

I got a div, I'd like some code to be executed onClick, that'd move the div to the top of the viewport (not to the top of the page), kinda like a "vertical float".
Is there a way to do this? I've seen annoying menus/ advertisements that stick to the top of the window even if you scroll down.

I have developed script library for dispalying calendar for my web
pages.
To display calendar, i am using div tag and with in div tag, i am
defining the dates.
This div tag is wrapped by IFrame control, in order to make the div tag
overlap over 'select' controls.
These controls (both Div and IFrame) are dynamically generated and i am
setting the width of div tag based on my text box associated with the
calendar.
IFrame width is determined by Div tag's offsetWidth.
This calculation works properly in IE 6.0, but when it comes to Firefox
1.5.0, the offsetWidth has been calculated wrongly and my calendar
shrinks abnormally.

I'm making a drop down box using offset so it's below the correct option, but if I resize the window, the dropdown box keeps the same offset as when the page was originally loaded.

I'm looking for an solution to find out the real vertical viewport -
without the height of horizontal scrollbars.
I have two frames side by side. The left one declared 'scrolling="no"'
and the right one 'scrolling="auto"'. For the left frame it is important
to know if the right frame has a horizontal scrollbar and how sick it
is. So I have tried to compare the viewport of both frames.
Using 'window.innerHeight', 'document.documentElement.clientHeight',
'document.body.clientHeight' or 'document.body.offsetWidth' I get the
height including the scrollbars.
The same problem with two frames (rows="50%,50%) i've solved with block
elements declared with a width of 100%. Comparing the offsetWidth of
both, I can see if there is a scrollbar in one frame. But with frames
side by side that doesn't work.

I am working on Javascript code that gets the size of the browser viewport. My code works perfecty if the page has content. But my code does not work at all if the page has no content. Try the code examples above to see what I am talking about. How can I make it work regardless of whether or not the page has content?

$().offset() does not return values on Chrome. Works well in IE and FF.
var element = r.circle(cx, cy, radius); // r.circle is from raphaeljs library.
var offset = $(element.node).offset();
Is there a work/fix around for this?

I'm using a CSS layout from one of the tutorial articles from this site (the butterfly one).
I cleared out the existing css menu, leaving only the empty space for it and threw a DHTML menu (hvmenu v5.4.11 from DynamicDrive.com) on top of the space.
As long as my content is less than 1 page, the menu will be perfectly centered. Once the content goes over a page, and the side scrolling bar appears, the menu (and only the menu) will get pushed 10 pixels to the right in Firefox and Opera. In IE the menu still remains centered. Both the css layout and the menu are set to be certered on the page, but the menu seems to center without taking into account the scrollbar (in firefox and opera only).

Collapse/Expand Button: The div to be expanded partially open (giving a preview in essence). After the button is pressed then the div would expand to show the entire contents (with a nice fade effect). If you chose to collapse the div then it would return to the original offset (preview) height. I've found a plethora of these scripts that fully expand or collapse, but not like this.

I have 50 thumbnails running vertically down the page, so that the viewer must scroll quite a bit to see them all. When a thumbnail is clicked I want to display the full size image in the middle of the viewport. Thus, the top offset of the absolute div that displays the full size picture will change depending on how far down the viewer has scrolled.
I can bind a function to the <img> tag that will set the top offset of the div where the full size images are displayed but I don't know how to get the current position of the viewport, or how to position something with respect to the viewport.
Can jQuery pull the viewport position out of the DOM and let me center something in it?

I have a bunch of floated divs and I want to increment a variable every time they 'jump' to the next line. When I try using offset() for this I get the same top,left cords for every single element. Is there any way of getting the actual offset? (I get the same result in FF and Chrome)

I have problems setting an offset of the LocalScroll-plugin (and the ScrollTo)[URL]If you click on one of the links (main-section), you'll see the divs are not lining up right. I guess it's about scroll to goes to div+padding+margin. Right? So, I'll have to adjust an offset.
My code:
$(document).ready(function(){
$('#Main').localScroll({

I think the offset() function returns node's position relative to document. The attached html file prints the offset value to console when the box is clicked. I expect the same value would be printed every times. However, when the script is run on iPad (with simulator), it print different value when I zoom and scroll to different position. This problem does not occurred in iPhone.

There is a long thread about this in the posiiton() reference page, but I am not finding a thread here in the forums, let alone a solution. I have some code that is trying to do calculations on the left and top attribute of child DOM elements. So, I have 5 divs (floated left, with width and height assigned), contained in another div. If I iterate over the 5 divs and call either position(), offset() or even css('left'), they always return 0. I have tried setting margin: 0px as well, but same result.

I have the below code to calculate how tall a 3rd div needs to be. This code works except for one flaw. It always seems to read the previous .top and .height() values.As .annoucement-area-880 and .content-annoucement-bottom-880 are dynamic (two different types of accordions) they resize depending on what element gets clicked.One uses the .animate() method while the other .slideDown().I tried enclosing the below within a $(document).ready(function(){...}); but this doesn't help.In conclusion, below code works fine except it reports previous (aka old) values which in effect cause it to calculate an currently invalid height.
Code:
var div1 = $( ".annoucement-area-880.id1" );
var div1_offset = div1.offset();
[code]....

I have an index file that contains absolute barebone html statements and a Flash application. The application is set internally to occupy 100% of the screen. Test site is Flipsauto.info I need to have a content area offset with a DIV statement but can't remember the syntax. In other words, the content area will contain text for search engine spiders to analyze but not be viewable by the user.

I just learned that firefox (v 1.5.0.3) chops any content of an iframe
that exeeds 2^15 (=32768) pixels i.e. in height? Any idea what went
wrong or is this a bug/feature?
I am using this code:

I'm using a simple toggle function to reveal divs when clicking on the associated heading. What I'm aiming to achieve:
1. When the heading is clicked, the hidden div will be revealed and the page scrolled so that the heading is at the top of the viewport.
2. If the page has insufficient height for the heading to move to the top, the page height will be increased to allow this to occur.
3. When the heading is clicked again, the div will be hidden but the heading remain in its current position at the top of the viewport. If a div is being toggled closed when not at the top, the page having been scrolled, then it should remain in its current position.
Other things to consider:
Preventing the amount of any generated empty space at the page bottom from being sufficient to fill the entire viewport.
Current state of play:
The code below will move the heading and revealed div to the top of the viewport if the page height is sufficient. When the div is hidden again, the heading drops down to its original location on the page, which is disorienting for the user.
Markup
<h2 class="trigger">Switch<h2>
<div>Content to toggle</div>
jQuery
$(document).ready(function() {
$('.trigger').next('div').hide();
$('.trigger').click(function() {
$('html,body').animate({scrollTop: $(this).offset().top}, 500);
$(this).next('div').toggle();
});
});
