Retrieves the object that has the focus when the parent document has focus.
[ oActive = ] document.activeElement
receives the element that has the focus.|
The property is read-only.
The property has no default value.
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.
The active element retains focus in the parent document even when focus is shifted from the parent to another application. If the focus returns to the parent document, focus also returns to the same active element.
For versions of Microsoft® Internet Explorer 5 and later, the activeElement
property is not defined until a document is loaded. A value of null is given for this property if accessed inline during the loading of a document. However, this property can be accessed from within the onload
event handler function.
Internet Explorer 4.0 returns body
as the activeElement
when accessed inline during the loading of a document.
There is no public standard that applies to this property.
