50582 - window.ondragdrop not cancellable with return false (NN4 compatibility)

Status: NEW

(Core :: DOM: UI Events & Focus Handling, defect, P3)

Description

[Martin Honnen]

With NN4 you can cancel the loading of a dropped link by returning false in the 
ondragdrop handler. This doesn't work in M17 (checked on windows 95) but should 
otherwise the ondragdrop handler is not compatible to NN4.

This bug has been marked "future" because the original netscape engineer working 
on this is over-burdened. If you feel this is an error, that you or another
known resource will be working on this bug,or if it blocks your work in some way 
-- please attach your concern to the bug for reconsideration.

The real problem is that the event is not implemented. YANNI.

OnDragDrop event is useful and necessary. It should be implemented for 1.4.

Currently the event isn't fired at all (the alert doesn't show), so this bug could be marked as a dup of bug 112288

See http://developer.mozilla.org/en/docs/DOM:window.ondragdrop - you can use e.stopPropagation() to cancel the loading:

window.addEventListener("dragdrop", testfunc, false);
function testfunc(event) {
    alert("dragdrop!");
    event.stopPropagation();
}
