How To Determine A Page Offset
Nov 5, 2011
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.

does anyone know how to determine page height so I could display the maximum number of ads in page. i.e. if page height is 600px it would show 5 ads, however if page height was 1200px it could show 12 ads. I have a fixed column on the right hand side of my page for ad space & I would like to maximize the height avaliable to display ads.

Is this possible?
Let me clarify: I need a way for a html page or something similar be able to determine what it's full path is. It must self-determine this.

I have a floating div that stays at the bottom of the browser window while the user scrolls down a long page. The div reads "scroll down for more". How can I determine the current position of the div in relation to the top of the page, not the top of the browser window. I need to determine this because I would like to hide the div when the user scrolls to the top of the last page. I have looked at offsetParent, offsetHeight, scrollHeight, etc.
I have the code for everything except determining the position of the div, or the distance of the div from the top of the page.

Is there a clean way to determine that a page has finished loading? I have a page that basically imports photos from Facebook or something simliar to that and when it's done executing I'd like it to redirect automatically to a different page. If JS or jQuery isn't the best way to do this I'm ok with using something else as well.

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?

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 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.

$().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 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({
[code]....

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();

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 know it's possible to retrieve the IP address of a visitor's computer. However, I need to figure out a way to get the IP address of the server where the files are placed. Here's a description of my issue:
My application, along with some HTML Electronic manuals, are loaded onto a server in an electronic classroom. In order to get to any of these items (manuals or app), the students access the server where an index page is located in the D drive and click a link to get to any of them.
The problem is that these manuals are loaded into the D: drive while my application, because it uses ASP, is saved in the C:inetpubwwwroot folder.
The other issue is that this application will not be placed in just one classroom. Each classroom will have its own server with any number of computers accessing it. Since I don't know how each of the servers will be set up, I need to get the IP address so I can access the wwwroot folder.
What I need to do is figure out, using some non-server-side language, what the IP address or computer name of the server is so that I can access the appropriate folder in the wwwroot folder.
