Determine Position Of Element From Top Of Page (not Browser)?
Jul 27, 2011
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.

I have no perfect cross-browser solution to position html element on
the bottom of the page. I know that with Firefox I do it as: position:fixed; bottom:0px;
However, IE does not understand that. Did anyone come across this issue to share with me?

i would like to know the absolute position of an element (e.g. <LI>) in the browser. i nned to know it in order to place juste beside another element (e.g. submenu).
for example: i have a <li> tag which is at 400px from my browser left border (because it is inside a div which is screen centered). this <li> has a width of 180 px so if i want to know the most left position for my submenu, i should get 400 + 180 = 580 px (from the browser left border).
i tried offset but without success. in fact it returns me 0.

I need to find the position of an element on the page relative to the browser window. Its part of a popup calendar script (and no, they don't want to change it so please don't suggest jQuery date-picker etc) The script uses these functions [url]... to find the position of the anchor to pop up the calendar next to it.
Now the client wants to make the calendar fixed when the user scrolls so that it always stays on screen. The most graceful solution is using css position:fixed (I'm aware it doesn't work in IE6 - that's not a problem)
I've been using the getAnchorWindowPosition function to get the coordinates but the numbers its giving are wrong (to different degrees depending on the browser) It was only 200px out in the Y axis in Firefox but in IE7&8 its off the screen.

I have a problem with currency formatter function I made. On onkeyup's
method of a textfield I add function below:
<snip>
function formatCurrency(elm) {
var str=elm.value;
var re = /(-?d+)(d{3})(,d*)?/
var re1 = /./g
str = str.replace(re1,'')
arr = str.split(',')
str = arr[0]
while (re.test(str))
str = str.replace(re, '$1.$2$3')
str += (arr.length 1) ? (',' + arr[1]) : ''
elm.value = str
}
</snip>
It works as I expected, except that after the function finished its
execution the cursor moves to the end of the textfield. So if I want
to insert two or more characters, the rest of it goes to the end of
textfield.
How I determine the position of the cursor in the textfield before
executing the regex?

How would I start to go about this? I'd like an <h3> to display and slide in whenever the user scrolls to a certain position on the page. For example, once a certain content div is 50% displayed in the viewport, I'd like the animation to fire.

I was editing some javascript code yesterday that happened to use jquery. Part of the code selected two elements via jquery. Then the original author used nodeIndex to determine the position of each of these nodes in their parents. I could not find any documentation on nodeIndex on the jQuery site or anywhere else on the internet. It seemed to work in IE8, but I did not see the property from FireBug in FireFox 3.5. So I removed the call to nodeIndex and used a for loop to calculate my own equivalent of the nodeIndex. Is nodeIndex officially supported or meant for internal use? Is it documented anywhere? [URL]

I was just wondering if there is a way to load a CSS file depending on the browser that you are using. In this case I am looking to load a CSS file for Safari only. maybe another option would be to use CSS hacks (but not webkit).

If you go on my test site: [URL]... You will see a navigation menu at the top, with an animated ball. Every time you click on one of the links in the navigation menu, you will notice that after a new page is loaded there is a sudden jump from the balls original position to it's new position. (Not that obvious in Firefox but very obvious in IE and Safari) My question is how can I resolve this.
I assumed that wrapping the code in the $(document).ready function would elimate this issue as everything inside it will load before the page contents are loaded.

If I had a webpage that displayed a database in tabular form, it would
be nice to know how many lines of text the browser could display
without scrolling, then have the cgi script output the appropriate
number of lines of data to fill the screen.
I've seen examples of how to get the browser window size in pixels, but
is there a way to determine the number of lines that are displayed?

I created this test routine to return the form containing a certain
input element:
function GetElementForm(element)
{
// Return the form that contains element.
varmyElement = element;
while (myElement)
{
myElement = myElement.parentNode;
if (myElement)
{
var sTagName = myElement.tagName;
if (sTagName)
{
if (sTagName.toLowerCase() == "form")
{
break;
}}}}
return myElement;}
This seems to work for "well formed" HTML, but fails for example, when
a form is defined within a table.

Im trying to find the correct syntax to use to determine whether which form
element is visible on changing the value in a dropdown list
I need something in the onChange of the dropdown list that will cause the
appropriate element on another part of the page to be displayed Code:
var mydropdownlist =
document.questform.typeid.options[document.questform.typeid.selectedIndex].v
alue;
if(mydropdownlist<6)
then display <input name="ans1" type="text" >
else
display <textarea name="ans1" rows="1" ></textarea>

Is it possible to dynamically determine the current field element in a
form?
I ask because I have a 'tab' button on a form, and when a user clicks
on it I need to be able to shift the focus to the next field, and also
if the current field is the last field on the form, essentially to do
nothing.
Conceptually, I guess I'm trying to do something like:
function clicktab(){
variable = current.field.element.number;
if (variable < n) {
variable++;
document.forms[0].element[variable].focus;
}}
In the above function, "n" would be the total number of fields in the
form.

I have this odd situation in which a function receives an element that needs some cleanup; all events to which it is bind to should be removed
Unfortunately, I don't know if the events are bind using 'bind' or 'live'
Is it possible to use find this out somehow using only this element ?

I have two textbox columnsof equal length they are accessed in the following manner:
taborder 1
taborder 2 taborder 3 taborder 4 taborder 5 taborder 6 taborder 7 taborder 8
When I leave the first textbox (taborder 1), I need to check and see if the textbox contains avalue. If it does, then I need to check and see if the second textbox (taborder 2)contains a value. If it doesNOT, then I need to loadthe second textboxwith "100" and highlight (select) the text. I am adding a blur event to all the column one textboxes as they all contain"rawCount" in the id. Here is my blur event code:
$(document).ready(function(){
$('input[id*=rawCount]').bind('blur', function (event) {
// Code to go here
});
});
What I am trying to do isadd thecode tocheck and update thecolumn two textbox in the corresponding row (same index)to the blur event of the column one textboxes without having to loop the array each time to find the current textbox array position. Since it is adding the blur event, it has to be possible.

thisID = this.id;
[code]....
The value of this.id is "platform_SWFUpload_0_0" but the result of thisID.match (pattern) is null.

All my font-sizes are set as relative sizes in CSS (large, medium, small,
x-small, etc). Let's say something is set in CSS to be xx-large, but a
visually impaired user wants it displayed even bigger. Can a script
determine an element's absolute size, *as it is being rendered by the
browser*, and then increment the element's font-size in absolute terms?

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.

Soliciting thoughts on the best way to determine the position of a click event.
Here's what I'm using right now but it's not working:
Code:
function getMousePosition(evt)
{
var x, y;
if(evt.pageX)
{
x = evt.pageX;
y = evt.pageY;
} else if (evt.clientX)
{
x = evt.clientX + document.body.scrollLeft - document.body.clientLeft;
y = evt.clientY + document.body.scrollTop - document.body.clientTop;
}
if(document.body.parentElement && document.body.parentElement.clientLeft)
{
var b = document.body.parentElement;
x += b.scrollLeft - b.clientLeft;
y += b.scrollTop - b.clientTop;
}
alert(x + ',' + y);
return [x,y];
}
The coordinates are WAY off in both firefox and IE. Can someone fix this?

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 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.
