Window.ondragdrop - Web APIs 编辑

Obsolete

This feature is obsolete.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.

Non-standard

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.

Summary

An event handler for drag and drop events sent to the window.

Syntax

window.ondragdrop = funcRef;
window.addEventListener("dragdrop", funcRef, useCapturing);

funcRef: The event handler function to be registered.

The window.ondragdrop property and the ondragdrop attribute are not implemented in Gecko (bug 112288), you have to use addEventListener. See addEventListener for details.

Example

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.

<html>
<head><title>dragdroptest</title>

<script type="text/javascript">

window.addEventListener("dragdrop", testfunc, false);

function testfunc(event) {
    alert("dragdrop!");
    event.stopPropagation();
}
</script>
