JQuery :: Calculate Position Of Image?
Oct 25, 2011
Do you know how to calculate position of image to move it to vertical center of screen? I mean especially the general problem of scrolling. The image doesn't change its absolute position, but when user scrolls or views a page with images, so he sees how the image gets more and more close to the top edge of screen, till the distance is 0. And now imagine the image is positioned absolute, 1000 from top. And on the screen it is at the position 0. How can I calculate its position from the top of screen?

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 will have two text boxes that will accept numeric values and an image. What I need is if the user change the value of box 1, the value in box 2 will automatically update depending on the pixel dimensions of the image and vice versa.
Basically I need to automatically calculate the pixel ratio of an image and then use that value to multiply by the user inputted size.

Here is the script I am working with courtesy of Build Internet
Here is the css that goes with it
I would like to randomize the value of the top position in the css and the value of right:'30%' with values in a preset range.

I've been looking for an "Ajax CMS" but decided to learn jQuery to learn how to code it myself in order to earn some geek-girl cred among my male colleagues. I've learn a lot about jQuery in a week but as you can imagine I still have a lot to learn.
I have successfully animated an image (move to the left and increase opacity) when the mouse hovers a div and reset the image (move it back to its original position and reset the opacity) when the mouse move outside the div. So far so good...
Here comes the question: What I need to do -and don't know how to - is when the user clicks on the div the image should stay in the hover position while still being able to hover any other divs and activate the animation normally.
When a different div is clicked the previous "Clicked" div should return (animate) to its original position and the new "Clicked" div should stay in the hover position. Content will be loaded when the divs are clicked but there won't be page refresh since I'm loading the content by using the load funtion of jQuery.
I'm including the code:

based on this script I wanted to know if it's possible for a div to change an image within it based on a certain x/y coordinate.For example if the div with the dog image here is moved to a certain point to the right, it would change to cat.jpg.

I need some help on how to reposition a layer depending on the position of an image? I know this should be somewhere in the forum, but I searched without success.
I mean like this:
<body onload="movemylayer()">
<img src="1.gif" id="myimage">
<div id="mylayer"></div>
</body>
...And when the page is loaded the layer moves infront of the image.

I wish to display some text dynamically below a series of images. I need to get the position of each image, and so I require some way of getting the position of an image in relation to the div holding the images.
I managed to get the position of the image in relation to the entire page, but this was no good for my purposes.

#navigation li is the parent element, which is positioned relative.The ul element above that is also position relative. I previously tested a click function and was able to confirm I was getting the correct position back, so now I just need to set the CSS property correctly for all of those links.The reason I want to do this is I have a set of links that appear over a photo of a city skyline. When you hover over those items, I want them to be given a background image that is a blurred and lightened version of the same photo so it needs to line up (sort of like the tabs are made of frosted glass).

I have found nice short tutorial here: Rounded_Corners
It works fine unless I try to move it.
I have added only one DIV over all:
Now I see that my text (white) moved but not background.
How do I properly position the whole DIV of class "roundbox" ?

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";

I'm using javascript (JQuery) to calculate the value of my textBox, "mMontantTextBox." I'm going to run into problems with this being a "read-only control" of my TextBox. In the first screen, I have a TextBox, mNombre50TextBox, the user fills in the number of tickets they want in the textBox.the sum is displayed (by calculating with jQuery) in another textBox, mTotal50TextBox, and the total bill is in 3th (another) textBox, ,mMontantTextBox... Then (when the user clicks a button), the information is backuped for the following screen on the second screen, I display the sum in a "Label", mPriceLabel, if my textBox, mNombre50TextBox, without "read-only control" :

For a project that would be too hard to explain, I am working with date ranges. There is a begin date and an end date. With those two variables, I need a function to calculate the number of months between both dates. To be more precise, I need a count of all unique month names in the dates (or month numbers if that is easier) where the range includes the beginning date, the end date, and all dates in between. So I am not looking for full months or an approximation. If only, say, one day of a given month is included in the date range, that adds a month. Also the range can span several years, january 2010 and january 2011 need to count for two different months.
