过时
This feature is obsolete.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.

非标
此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。

Removed in Firefox 50, and never implemented in any other browser. Use the modern standard HTML5 drag and drop feature instead.

摘要

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

句法

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

funcRef

window.ondragdrop 特性和 ondragdrop attribute are not implemented in Gecko ( bug 112288 ), you have to use addEventListener 。见 addEventListener 了解细节。

范例

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>
</head>
<body>
I am bodytext
</body>
</html>
