absolutize(element)

Turns element into an absolutely-positioned element without changing its position in the page layout.

clone(source, target[, options]) -> [Number, Number]

Clones the position and/or dimensions of source onto target as defined by the optional argument options.

cumulativeOffset(element) -> [Number, Number]

Returns the offsets of element from the top left corner of the document.

offsetParent(element) -> HTMLElement

Returns element’s closest positioned ancestor. If none is found, the body element is returned.

overlap(mode, element) -> Number

Returns a Number between 0 and 1 corresponding to the proportion to which element overlaps the point previously defined by Position.within. mode can be set to either vertical or horizontal.

page(element) -> [Number, Number]

Returns the X/Y coordinates of element relative to the viewport.

positionedOffset(element) -> [Number, Number]

Calculates the element’s offset relative to its closest positioned ancestor (i.e., the element that would be returned by Position.offsetParent(element).

prepare()

Calculates document scroll offsets for use with Position.withinIncludingScrolloffsets.

realOffset(element) -> [Number, Number]

Calculates the cumulative scroll offset of an element in nested scrolling containers.

relativize(element)

Turns element into an relatively-positioned element without changing its position in the page layout.

within(element, x, y) -> Boolean

Indicates whether the point x, y (measured from the top-left corner of the document) is within the boundaries of element. Must be called immediately before Position.overlap.

withinIncludingScrolloffsets(element, x, y) -> Boolean

Indicates whether the point x, y (measured from the top-left corner of the document) is within the boundaries of element. Used instead of Position.within whenever element is a child of a scrolling container. Must be called immediately before Position.overlap and immediately after Position.prepare.
