Remarks

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, and this causes HTMLAreaEvents::onfocusin to fire for this 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, and this causes HTMLAreaEvents::onfocusin to fire for this active element.

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 HTMLAreaEvents::onfocusin event to manage formatting changes when an element gains focus.

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

To invoke this event, do one of the following:

  • Click a document, when the document does not have focus.
  • Click an element, when the element does not have focus.
  • Use the keyboard to move focus from the active element to another element.
  • Invoke the IHTMLElement2::focus method on an element, when the element is not the active element.
