Sets or retrieves the y-coordinate, in pixels, of the mouse pointer's position relative to a relatively positioned parent element.
Remarks
With Microsoft® Internet Explorer 5.5 and later, focus on a document, and the active element of a document can be managed separately. Use the onbeforedeactivate event to cancel moving activation from the current element.
Note When focus leaves the document, the active element does not change and the onbeforedeactivate event will not fire.
Each document may have up to one active element. Set the active element with the setActive or focus methods. Using the setActive method has no effect on document focus. Using the focus method on an individual element causes the element to gain focus and become the active element.
Using the focus method on a document that does not have the focus moves the document to the front of the display. Additionally, the document's active element gains focus.
For a given display, only one element has focus at any given time. Striking a key directly affects only the element with focus. Events fired by that keystroke may be scripted to affect other documents and child elements.
