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.
To invoke this event, do one of the following:
- Click an element, other than the active element of the document.
- Use the keyboard to move focus from the active element to another element.
- Invoke the setActive method on an element, when the element is not the active element.
- Invoke the focus method on an element, when the element is not the active element.
