I just thought this might require some javascript, so I posted this here. Anyway, how do I create an element that is absolutely positioned first, and then, when it goes to the top of the page, it becomes fixed?

I have some fixed or absolute positioned DOM elements in the whole document for some purpose, How can I traverse the whole document to get the above mentioned elements, any jquery method to be there please let me know,
View 3 Replies View RelatedBecause of the nature of my page, I would like to animate a div from a fixed postion when someone first visits the site to an absolutely position location using after clicking a menu item using .animate and the easing effects. This part seems to work fine, however, when I click on the "home" button again, the div will not move back to the original fixed position. The div just sticks to the top of the page. My assumption is that the .animate scriptdoesn't' know how to interpret/find the fixed position location. Is there a way to make this work?

I'm new to javascript and am not sure why this works in firefox and not chrome. I am trying to create a script that keeps an object fixed horizontally while bing positioned absolute vertically. if I replace the toPP variable in document.getElementById('fire').style.top = toPP; with say '50px' it will move the element down 50 pxs, but how I have it currently it doesn't do anything in chrome
<script type="text/javascript" >
window.onscroll = function()
{
if( window.XMLHttpRequest ) {
var x = 0 -document.documentElement.scrollTop;
var toP = String(x);
var toPP = toP + "px";

Before you immediately give me an answer, let me describe fully what I'm trying to do, as it's not as simple as the title suggests.
I need to get the absolute position of a DIV (top and left properties) relative to the viewport/screen.
I've tried using .offsetTop and .offsetLeft, but these return the top and left properties relative to the DIV's immediate parent element, not the viewport (unless of course the DIV is top-level and not contained in any other DIVs).
So, is there any way to retrieve the absolute position of a DIV relative to the viewport, even if that DIV is nested in other DIVs?

<div id="logopart">logopart</div>
<div style='display:inline;'>
<div id="leftmenu">leftmenu</div>
<div id="cont">cont</div>
</div></div>
How do I put "cont" div on the right of "leftmenu" without using "absolute"?? The screenshot was little bit cropped out and there is no problem on width.
Its said that placing the absolute div within a relative div is a best option to correctly achieve the margins within that relative div. However, I'm changing the marginTop and marginLeft via javascript and after some of the changes it shows the absolute divs in incorrect positions in IE.
What i want to do is calculate the vertical-middle right-sided position of text fields in x, y meaning in top and left margins. How can I do that?
I am trying to create a menu system.
The mainmenu is a table
<table><tr><td>menu1</td><td>menu2</td></tr></table>
No I try insert the submenu so that it becomes relative to the main menu
item. For menu1 the relevant code then becomes:
<td style="position:relative;">menu1<div style="position:absolute; top:20;
left:0;">
<a href=x.htm>option1</a><br>
<a href=y.htm>option2</a>
</div></td>
This works fine in IE: the div is positioned relative to the td of menu1.
However, in Mozilla it doesn't work. The div becomes relative to the top of
the page.
What am I doing wrong?
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 got a script from brothercake which gets the absolute position for an element. Its pretty neat - recursively adding up offsets. I got it from the image transition scripts on his site.
However, this script uses offsetTop, offsetLeft and offsetParent, which dont seem to be supported by FireFox (or maybe I'm doing something wrong).
Here's brothercake's script:
getRealPosition = function()
{
this.pos = (arguments[1] == 'x') ? arguments[0].offsetLeft : arguments[0].offsetTop;
this.tmp = arguments[0].offsetParent;
while(this.tmp != null)
{
this.pos += (arguments[1] == 'x') ? this.tmp.offsetLeft : this.tmp.offsetTop;
this.tmp = this.tmp.offsetParent;
}
return this.pos;
}
It seems to work for Opera and IE - but not FF. Cant say for other browsers. I've come to rely on it for a part of my 'cross-browser' page. Any thoughts on what I can do?
What I can't figure out is why it seems to work fine on brothercake's site - even in FireFox. I'm supposing that the positioning script must be working because the images appear in the right spot.
The following works in IE, but not in firefox:
document.getElementById('mydiv').style.left = event.clientX + document.body.scrollLeft;
document.getElementById('mydiv').style.top = event.clientY + document.body.scrollTop;
Any ideas why?
I have a div with headers. Of course, when there are too many rows, you have to scroll and lose the headers of the form. How can I accomplished "fixed headers?" so that they're always visible?

We dynamically create a page with multiple segments which are relatively
ordered among each other. In these segments we have input fields.
When such an input field is focused I need it's absolute position.
Is there a way to do so with IE > 6?
I'm using the code below to display a menu that opens when the mouse
goes over the main menu item (try it in your browser to understand the
behaviour).
It uses "position:absolute" and a switch between "display='none'" and
"display=''".
However the problem is that
- in Internet Explorer 6 the dropdown (<select>...) always hides the
menu
- in Mozilla the menu is hidden initially but after clicking on the
text "Select" it isn't hidden.
How does that come and how can I overcome it?
I want the menu to be above the other stuff when it comes up. Code:
i have been looking for a script like this for a few weeks now, and i
am finally giving up and asking for help. everything i found involved
preventing overlap in dreamweaver, i want to prevent it in the output
on all of the browsers.
basically i have a page that has absolute layers (cannot be relative)
with the coordinates top/left in the db. but sometimes on certain
pages the layers overlap. I cannot set a static size for those layers.
so i was wondering if anyone has a script, that will check for any
overlapping of layers, and if it overlaps, to move the layer to the
right, or down, until it no-longer overlaps. i can modify anything
similar if you have it.
i wonder if there's a way to find an absolute position of a div-layer from the bottom of the page with some jquery-code.
i need the bottom-value of this container, because my elements are positioned from the bottom of the page.
I have an absolute positioned navigation on my page that makes you jumps up or down the page to view some pictures placed in another absolute positioned DIV with scroll bar. The navigation is simply made by numbers: 1 2 3 4 5 6. When you rollover 2 is underlined and onclick the page jumps down to the second picture and the number 2 stays underlined, and so on for 3 4 5 6. The style changes this way
HTML
<span id='first' class="selected"><a href="#1" onclick="first()">1 </a></span>
<span id='secondo' class="normal"> <a href="#2" onclick="second()">2 </a></span>
and so on for 3 4 5 6

What I would like to do is to make the style change automatically also when the user scroll the page instead of clicking. I thought I could control the y coordinate with window.onscroll but because what scrolls is the DIV and not the page the window.onscroll doesn't work. Is there a way to control the same way the scroll of a DIV? Or should I build the site differently?
I am working on a puzzle that produces a container div.Within that div are produced a grid of 9.16. or 25 tiles.The tiles are positioned absolutely so I can be sure of their relative placement. The container div width and height is calculated according to a preset tile width and height (square actually). So the width of the container should adjust to either 3,4 or 5 tile widths and heights.The trouble is that the offset position of the top left tile is different relative to the container for each different set of tiles (even though it is supposed to be the same position relative to the container for each). I do this so I can apply dragging to the container div.The tiles will follow the container when it is moved and the game will not loose its place when tiles swap locations.(one tile is elected as blank, and tiles, one to left, right, top
or bottm, with game content, will swap location with blank when clicked)
I need to write to certain element on web page through some kind of absolute path access.
Example structure code...
I am using position absolute to stick a table header to the top of a div. In the screenshot, under the menu is a div, the buttons and drop downs are at the "top" and grid starts from half way down, now when user scrolls till header is out of view i show the header at the "top" with position absolute. then when user scrolls back down and onto original position the buttons and drop downs are now again at the top exactly at the position where the header was shown, once the header has been shown all the buttons and the drop down are no longer clickable, i.e. there is no reaction, no dropdown shown and no click... whats happening is that IE is thinking that that area at the top where the header was is now invalid, or still occupied by the header or something like that? Its like the buttons and drop downs are kind of "behind" the area where the header was therefore nothing is clickable...
And proof of this is that i gave some <BR> spacing to the buttons and drop downs so that they are not at the up most, but halfway down... and things work fine... whats IE up to? or is there some coding i need to do... below is the code for the header to float
[it may be coz when the header is not to be shown i set the position to ' ', but i have tried with relative, fixed and static as well to no avail...]
<script language="javascript" type="text/javascript">
var floating_header = function() {
this.header = document.getElementsByTagName('THEAD')[0].getElementsByTagName('TR')[0];

I'm just figuring out how to use absolute inside a relative element to shift an image without changing the flow of the rest of the html. It's working for Firefox 4, but not IE 9.
In firefox the div element doesn't cause a hole in the flow. The div and the image inside is simply moved over to where they should be. But in IE, the image is sitting there as part of the flow bumping down the next things (the text and span tags) and the image isn't moving over to the right at all.
I've tried wrapping the div in an another div but that made no difference. Am I crazy to think this is supposed to work? I'm inserting the div and image tags dynamically in the client in javacript.

I'm trying to get the height of an element that contains content which is absolutely positioned. As far as I can tell, because the absolute positioned content is taken out of the page flow, you cannot retrieve the 'visible' height (ie height as seen onscreen) of the element with properties like clientHeight / offsetHeight.
Is there any way to access the visible height of an element like this?
I have following problem: I get screen coordinates something (which might not be a mouse) and have to convert them relative to an element on a page.
Inside a page it's simple: use the offsets to the parent elements.
On the other side the start are the window.screenX and window.screenY coordinates.
The only problem now is how to find out the offset from the page to the window, i.e. the size of the toolbars and stuff? What might be interesting are the mozInnerScreenX/Y attributes of an window. But these are only present in firefox, obviously, which is not sufficient.
A hack would be a calibration page which uses a mouse event to calculate the missing offset using evt.pageX/Y and evt.screenX/Y. But this might not work, since a mouse might not be present.
