I got an element ( say <div id="foo">... ) at its natural position in a
page.
I need to get the distance (in pixels) between the top of that element and
the top of the page/frame.
Of course, I'd prefer this to work with IE and Mozilla family.
I've used Brian Crays driving distance calculator on a site, however the calculations are not accurate for full addresses. I realise the v2 google maps api is now depreciated, my question is, if I upgrade to v3, is there more accurate calculations of distance and if so, does anyone have an example of calculating the distance between two points with the new api?
or does anyone know how to get more accurate results with his code?
how would i get the distance and angle between 2 points on the screen.
For example:
what is the distance between (100,50) and (250,70)
what i really wanna do is see how far the current mouse position is
from a given object and what the angle is between them.
What i'd like is a simple converter to allow a user to input the distance travelled
in miles and the time in hours and minutes, the result being an average speed. What i'd appreciate is for someone to write the script for me and post here if possible.
I'm looking for a jquery tutorial which helps on calculating the distance between two points?
I've found a few javascript ones, but its breaking the rest of my jquery code!
does anyone know of anything? im using it to calculate a price for a specific distance traveled.
i've found out how to find the distance between 2 lat lng points using google's distanceFrom method:
Code:
// NR14 7PZ
var loc1 = new GLatLng(52.5773139, 1.3712427);
// NR32 1TB
var loc2 = new GLatLng(52.4788314, 1.7577444);
alert(loc2.distanceFrom(loc1) / 1000);
However, I'd like to be able to convert a distance to lat lng. The main reason I'm doing this is so that I can figure out the bounds of a certain area of a co-ordinate. For example I specify a point, and then I need to draw a box around this area going x distance North, South, East and West, but until I know how many units make up a kilometre this wont be easy.
I guess I could go to google maps, click on a point and then click on another point and keep doing that until I get exactly 1km away from the original point, then just minus or plus for the lat and lng to find out the unit value for 1km, but I have a feeling that this wont be accurate. Can anyone lend any advice, I realize that what I'm asking is more a map question than a google maps javascript api question, but perhaps someone has come across this before?
A piece of html code:
<table>
<tr>
<td>
<input type="text" name="myInput" onclick="myFunction(this)">
<td>
</tr>
</table>
myFunction(el) {
alert(el.offsetTop)
}
Alert shows the distance from input to the top of the table or table cell.
Is there any other attribute which shows the absolute distance from input to
the top of the page ? Because of some reasons I can't add table's and
input's offsetTops.
I've got this lovely little animation that slides some div fields to the right a short distance. Everything works except the setTimeout (located in the SlideIn function). It simply 'jumps' without taking any time at all. I've tried a bunch of stuff:
changed the amount of time from 100 to 10000
changed it from var t = setTimeout("SlideIn()", 1000)
SlideIn with/without the brackets, with/without the quotation marks.

I am doing some work, where I want to have a table heading that remains in a fixed position, when the window is scrolled (I will ultimately have a very long table). I have written the code below, which fixes the heading.
I am trying to make it so that each body row of the table gets hidden, when the window is scrolled such that the row passes above the heading row.
To do this I need to somehow detect the distance of each row from the top of the window as the window is scrolled so I can detect when it goes above the fixed heading row. I have tried to do this using offsetTop and scrollTop in the code below, but it doesn't seem to be working (in Safari at least, which I am using for my main testing).
Does anyone know a simple way of detecting the distance to the top of the window so I can use it in my code below, which will work in all browsers?
(I don't really want to use div, and overflow-y:auto to achieve the fixed heading scrollable table, because I don't want to have a sub-section with its own scrollbar. I just want to have the main page scrollbar when the list gets long enough to require it.)

I've found the Harvesine forumla to get the distance between any two points of latitude and longitude on the earth's surface. What I want is a little different - I want that, given a point and a distance, to get the latitude and longitude of a second point. I'm having trouble reversing the forumla. The current formula:

In all the easing functions (based on Robert Penner), I see that they require the distance to travel to be known beforehand. But what if I didn't know that? How would I calculate the change to position based on easing my speed to zero if I know my current speed?
In other words, I know my start position, my current speed and the duration. I want to figure out the change in position (for each step and total change).
I'm currently doing on a project, frankly speaking i'm new in javascript only know the basics. I'm not even sure whether this thread is suppose to be here or under html.. I'm suppose to create some codes that enable a html page to load to the next html page when the mouse move from left to right within a specific time and distance(positive X coordinate) and also the other way round (right to left) once i figured out this. I've got an example online and edited it. Please take a look at my codes.

test01.html is just blank page created to make sure it loads. However i would like to load from test01 to another html page but no matter how i tried to edit the codes, there's errors. I cant possibly copying and pasting the exact codes to every page i want to load to right? And is it possible to sortof increase mouse sentivity such that i can most probably load to the next page in first few tries of moving the mouse on the first page. Is it common that when i launch the html on IE and Firefox somehow after showing the first page for maybe 1 second, it immediately jumped to 2nd page and i have to go back to 1st page to try out.
My goal is to load the JS for a specific element before displaying that element. I integrated a third part script, and it works well. I set the timer here:
The JS is in my heading as <script type="text/javascript" src="countdownpro.js"></script>
About mid-body I have: <span id="countdown1">2010-07-20 00:00:00 GMT+00:00</span> which allows for the setting of a target date to countdown to.
When the page first loads it shows the above long format target time, until the js/meta tags kick in to modify it to just show the actual countdown as 00:00:00.
I have attached countdownpro.js to this post. I tried shifting the function CD_Init() to the top of the script, and also appended it inline with the .html. I tried setting the big external script to "defer", but neither arrangement worked. I also tried placing the src file right at the top.
When the page loads there will already be a drop-down on the page, here's an example of the drop down.
<select id="dropdown">
<option value="2121S">Option text</option>
<option value="2122S">Option text</option>
<option value="2123S">Option text</option>
<option value="2121A">Option text</option>
<option value="2122A">Option text</option>
<option value="2121K">Option text</option>
</select>
On page load it will evaluate this drop-down and repopulate it determined on their values. If there is an S in any of the values the drop-down will generate an option for 'S' like so.. <option value="s">S Option Text</option> And for the first code example in this post - the Javascript would be able to repopulate the drop-down with the following:

i have a menu generated by a list with nested lists. i want the parent link to stay highlighted when the mouse hovers over the sub menus. because those sub menus are also generated by jquery (qtip), CSS alone won't do it (triedul.topnav li:hover a {background-color: #F00;}).is there a way to do this using jquery?

I have that page above.. But the thing is the entire website was made using an iFrame that loads another page.. Each page has one of those at the bottom. Thing is when the main page loads the second page, there are duplicates of those at the bottom. I want it so that when there are duplicates, I can remove the main one. How would I even get started on that? I don't know where to look at all.
I looked up stuff but the only thing I found was the remove html elements using $('.class').remove(); Which doesn't do what I want. I only know very little javascript, lots of css, lots of html and lots of C++.. I don't know any other languages.
Is there any way to capture the Id of an element being clicked within a page?
