Remarks
The HTMLAreaEvents2::ondrop event fires before the HTMLAreaEvents2::ondragleave and HTMLAreaEvents2::ondragend events.
When scripting custom functionality, use the IHTMLEventObj::returnValue property to disable the default action.
You must cancel the default action for HTMLAreaEvents2::ondragenter and HTMLAreaEvents2::ondragover in order for HTMLAreaEvents2::ondrop to fire. In the case of a div, the default action is not to drop. This can be contrasted with the case of an input type=text element, where the default action is to drop. In order to allow a drag-and-drop action on a div, you must cancel the default action by specifying window.event.returnValue=false in both the HTMLAreaEvents2::ondragenter and HTMLAreaEvents2::ondragover event handlers. Only then will HTMLAreaEvents2::ondrop fire.
As of Microsoft Internet Explorer 5, drag-and-drop events can be used to carry out drag-and-drop activities, not only with input type=text elements, but also with block and inline tags. For example, text can be selected, dragged, then dropped on a div target. This causes several target events to fire, including HTMLAreaEvents2::ondragenter, HTMLAreaEvents2::ondragover, and HTMLAreaEvents2::ondrop. Because drag-and-drop actions are not directly supported on block and inline tags, you must use extra scripting to carry out the move or copy to the target using IHTMLElement::innerText, for example.
Calls the associated event handler.
To invoke this event, do one of the following:
- Drag the selection over a valid drop target and release the mouse.
