This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
Removed in Firefox 50, and never implemented in any other browser. Use the modern standard HTML5 drag and drop feature instead.
An event handler for drag and drop events sent to the window.
window.ondragdrop = funcRef;window.addEventListener("dragdrop", funcRef, useCapturing);
- The event handler function to be registered.
Fire an alert on dragdrop
In this example, an event listener is added to the window (the event target). If, from an external source, a tab, a link, marked text or a file is dragged and dropped onto this window, the alert is fired. Note how
event.stopPropagation(); prevents the browser from loading the dropped tab, link or file.
Not part of specification.
