Javascript 但是，文件删除在MacOSX safari silverlight 4/dragenter和dragleave上不起作用

当我将一个文件拖到应用程序中（在我的MacBookAir上）时，silverlight函数就会启动。但是，当我在应用程序中释放文件时，应用程序崩溃。下面是javascript代码：

    function onSilverlightLoad(sender, args) {
        if (window.navigator.userAgent.indexOf('Safari') >= 0) {
            var objControl = document.getElementById('SLObject');
            objControl.addEventListener('dragenter',
        onSilverlight_HandleDragEnter, false);
            objControl.addEventListener('drop',
        onSilverlight_handleDropEvent, false);
            objControl.addEventListener('dragover',
        onSilverlight_HandleDragOver, false);
            objControl.addEventListener('dragleave',
        onSilverlight_HandleDragLeave, false);
        }
    }
    function onSilverlight_HandleDragEnter(oEvent) {
        // Prevent default operations in DOM
        oEvent.preventDefault();
        var flag = oEvent.target.dragEnter(oEvent);
        // If handled, then stop propagation of event in DOM
        if (flag) { oEvent.stopPropagation(); }
    }
    function onSilverlight_HandleDragOver(oEvent) {
        // Prevent default operations in DOM
        oEvent.preventDefault();
        var flag = oEvent.target.dragOver(oEvent);
        // If handled, then stop propagation of event in DOM
        if (flag) { oEvent.stopPropagation(); }
    }
    function onSilverlight_HandleDragLeave(oEvent) {
        // Prevent default operations in DOM
        oEvent.preventDefault();
        var flag = oEvent.target.dragLeave(oEvent);
        // If handled, then stop propagation of event in DOM
        if (flag) { oEvent.stopPropagation(); }
    }
    function onSilverlight_handleDropEvent(oEvent) {
        // Prevent default operations in DOM
        oEvent.preventDefault();
        var flag = oEvent.target.dragDrop(oEvent);
        // If handled, then stop propagation of event in DOM
        if (flag) { oEvent.stopPropagation(); }
    }

我在html页面的主体中使用了这两行

    <object id="SLObject" data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%" >
     <param name="onLoad" value="onSilverlightLoad" />

我认为silverlight在MacOSX上不支持它，所以我必须使用javascript来启动silverlight函数。它对dragenter和dragleave有效，但对drop事件不起作用。完全正确。我的错。这个页面有帮助吗？我注意到他们设置的东西与你的例子有点不同。还有一个：令人惊讶的是，有这么多的本土黑客似乎解决了这个问题。作为一个初学者，即使使用这些URL，我也找不到解决方案。我还发现：和或。
