YUI onDragDrop 多个监听器
我想知道是否有人知道一个示例,该示例显示 YUI DDProxy、DD 或 DDTarget onDragDrop 事件的多个侦听器。目前我有一个破解的例子。我正在使用 http://developer.yahoo.com/yui/examples/datatable/dt_ddrows.html'>DataTable Reorder Rows 示例。我把它修改成了几个js类。他们重写 DDProxy 的一个对象处理 onDragDrop 事件,但似乎如果在这里处理它,那么没有其他东西可以捕获该事件。检查片段:
YAHOO.extend(YAHOO.example.DDRows, YAHOO.util.DDProxy, {
//snip
onDragDrop: function(e, id) {
if (id == "right-function-pane") {
alert("In the right drop place");
YAHOO.util.DragDropMgr.refreshCache();
}
}
在创建 DDRows 的类中,我也想监听这里的事件。有些动作在某些地方更合适。我想听两地的活动。这是我在课堂上所做的构建上述内容的过程:
onDropHandler: function(e, id) {
DragDropTable.myDataTable.deleteRow(YAHOO.util.DragDropMgr.dragCurrent.id);
},
rowInitializer: function() {
var i, id, myDDRow,
allRows = DragDropTable.myDataTable.getTbodyEl().rows;
for (i = 0; i < allRows.length; i++) {
id = allRows[i].id;
// Clean up any existing Drag instances
if (DragDropTable.myDTDrags[id]) {
DragDropTable.myDTDrags[id].unreg();
delete DragDropTable.myDTDrags[id];
}
// Create a Drag instance for each row
myDDRow = new YAHOO.example.DDRows(id);
myDDRow.srcData = DragDropTable.myDataTable.getRecord(id).getData();
myDDRow.onDragDrop = DragDropTable.onDropHandler;
DragDropTable.myDTDrags[id] = myDDRow;
}
}
似乎如果一个人在听,另一个人就不起作用。我还没有找到允许事件继续冒泡或对 onDragDrop 进行多个订阅的语法。有人有正确的语法吗?

I was wondering if anyone was aware of an example that shows multiple listeners to the YUI DDProxy, DD, or DDTarget onDragDrop event. Currently I have a hacked up example going. I'm using the http://developer.yahoo.com/yui/examples/datatable/dt_ddrows.html'>DataTable Reorder Rows example. I've modified it into several js classes. One object they override DDProxy for handles the onDragDrop event but it seems that if it's handled here then nothing else catches the event. Check the snip:
YAHOO.extend(YAHOO.example.DDRows, YAHOO.util.DDProxy, {
//snip
onDragDrop: function(e, id) {
if (id == "right-function-pane") {
alert("In the right drop place");
YAHOO.util.DragDropMgr.refreshCache();
}
}
In a class that does the creation of DDRows, I want to listen to the event here as well. Some actions are more appropriate in some places. I want to listen to the event in both places. Here's what I'm doing in class that builds the above:
onDropHandler: function(e, id) {
DragDropTable.myDataTable.deleteRow(YAHOO.util.DragDropMgr.dragCurrent.id);
},
rowInitializer: function() {
var i, id, myDDRow,
allRows = DragDropTable.myDataTable.getTbodyEl().rows;
for (i = 0; i < allRows.length; i++) {
id = allRows[i].id;
// Clean up any existing Drag instances
if (DragDropTable.myDTDrags[id]) {
DragDropTable.myDTDrags[id].unreg();
delete DragDropTable.myDTDrags[id];
}
// Create a Drag instance for each row
myDDRow = new YAHOO.example.DDRows(id);
myDDRow.srcData = DragDropTable.myDataTable.getRecord(id).getData();
myDDRow.onDragDrop = DragDropTable.onDropHandler;
DragDropTable.myDTDrags[id] = myDDRow;
}
}
It seems like if one is listening the other isn't working. I haven't found the syntax for allowing events to continue to bubble or to have multiple subscriptions to onDragDrop. Does anyone have the correct syntax?
Thanks
