Standards information

There are no standards that apply here.


Note  When focus leaves the document, the active element does not change and the HTMLTableEvents2::onbeforedeactivate event will not fire.

Each document may have up to one active element. Set the active element with the IHTMLElement3::setActive or IHTMLElement2::focus methods. Using the IHTMLElement3::setActive method has no effect on document focus. Using the IHTMLElement2::focus method on an individual element causes the element to gain focus and become the active element.

Using the IHTMLElement2::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.

With Microsoft Internet Explorer 5.5 and later, focus on a document, and the IHTMLDocument2::activeElement of a document can be managed separately. Use the HTMLTableEvents2::onbeforedeactivate event to cancel moving activation from the current element.

Change activation from the event. IHTMLEventObj::srcElement to the event. IHTMLEventObj::toElement.

To invoke this event, do one of the following:

The pEvtObj parameter is required for the following interfaces:
