【求Ext拖动问题】Ext.dd.DropZone

问题描述：Ext6拖动后无法获取到目的地的相关属性。

代码：（拿API中的demo举例 - dragdropzones.html）

问：如何在拖动释放鼠标后的 onNodeDrop 监听方法里获取到 hospitals 对象中的属性（如 code、name、address等）？ 谢谢！

【附代码】

function initializePatientDragZone(v) {
v.dragZone = Ext.create('Ext.dd.DragZone', v.getEl(), {

    getDragData: function(e) {
        var sourceEl = e.getTarget(v.itemSelector, 10), d;
        if (sourceEl) {
            d = sourceEl.cloneNode(true);
            d.id = Ext.id();
            return (v.dragData = {
                sourceEl: sourceEl,
                repairXY: Ext.fly(sourceEl).getXY(),
                ddel: d,
                patientData: v.getRecord(sourceEl).data
            });
        }
    },


    getRepairXY: function() {
        return this.dragData.repairXY;
    }
});

}

function initializeHospitalDropZone(v) {
var gridView = v,
grid = gridView.up('gridpanel');

grid.dropZone = Ext.create('Ext.dd.DropZone', v.el, {


    getTargetFromEvent: function(e) {
        return e.getTarget('.hospital-target');
    },


    onNodeEnter : function(target, dd, e, data){
        Ext.fly(target).addCls('hospital-target-hover');
    },

    onNodeOut : function(target, dd, e, data){
        Ext.fly(target).removeCls('hospital-target-hover');
    },

    onNodeOver : function(target, dd, e, data){
        return Ext.dd.DropZone.prototype.dropAllowed;
    },

    onNodeDrop : function(target, dd, e, data){
        var rowBody = Ext.fly(target).findParent('.x-grid-rowbody-tr', null, false),
            mainRow = rowBody.previousSibling,
            h = gridView.getRecord(mainRow),
            targetEl = Ext.get(target),
            html = targetEl.dom.innerHTML;

        if (html == 'Drop Patient Here') {
            html = data.patientData.name
        } else {
            html = data.patientData.name + ', ' + targetEl.dom.innerHTML;
        }

        targetEl.update(html);
        Ext.Msg.alert('Drop gesture', 'Dropped patient ' + data.patientData.name +
            ' on hospital ' + h.data.name);
        return true;
    }
});

}
