As mentioned in the title, I am looking for a way to retrieve the x and y positions of an element relative to its location on the webpage and based on its positioning schemes such as absolute or relative.

When working in a modern web browser, utilizing methods such as getBoundingClientRect and getClientRects will provide detailed information about the positioning of your element. Check out this link for more insights on these functions.
For compatibility with older browsers like IE8, it may be necessary to implement different strategies for obtaining accurate results across various platforms. This could involve feature detection for getBoundingClientRect and implementing alternative approaches if needed.
Be cautious when using jQuery's offset() or Quirksmode's findPos functions, as they may yield inaccurate results in browsers that support subpixel positioning (such as Firefox or IE9). These methods tend to round values to whole pixels, which might not always meet your requirements.
Utilizing jQuery:
var $element = $('select a specific element here'),
position = $element.css('position'),
coordinates = $element.offset(),
topPosition = coordinates.top,
leftPosition = coordinates.left;
If you prefer not to use jQuery, refer to Quirksmode's findPos function:
var element = document.getElementBy...,
positionArray = findPos(element),
topCoordinate = positionArray[1],
leftCoordinate = positionArray[0];
Retrieving the computed CSS position value without a library can be somewhat tricky as highlighted by this discussion. Main approaches include:
element.currentStyle (for IE)getComputedStyle(element) (for modern browsers)Take a look at this
JavaScript Function:
function findPosition(element) {
var leftPos = topPos = 0;
if (element.offsetParent) {
leftPos = element.offsetLeft
topPos = element.offsetTop
while (element = element.offsetParent) {
leftPos += element.offsetLeft
topPos += element.offsetTop
}
}
return [leftPos, topPos];
}
Sample HTML Element:
<div id="ser"> TEST</div>
Call to the Function:
alert(findPosition(document.getElementById('ser')));
