stopPropagation 不适用于 YUI 2.7 中的 KeyListener

我创建了一个新的 YAHOO.util.KeyListener 来附加到特定元素，还创建了另一个新的 YAHOO.util.KeyListener 来附加到整个文档。它们都与 enter 键（键：13）相关联。

在附加到特定元素的侦听器的处理函数中，我有以下代码：

            getDetailsLocalnameInput = function(e) {
                    getDetails(localnameInput.value);
                    YAHOO.util.Event.preventDefault(e);
                    YAHOO.util.Event.stopPropagation(e);
            };

然而，来自按键的事件继续传播到附加到整个文档的按键侦听器。我不希望启动附加到整个文档的关键侦听器的处理程序。我确信两个处理程序都被调用，但只希望附加到特定元素的处理程序运行。

将 YAHOO.util.Event.stopPropagation 与 YAHOO.util.KeyListener 一起使用是否正确？

我是否应该采取不同的方法来防止传播 keypress 事件？

我还尝试使用函数 YAHOO.util.Event.stopEvent 并设置 e.cancelBubble 但没有成功。

我已经用 Firefox 3.5 测试了所有这些。我根本无法让 stopPropagation() 工作。

I have created a new YAHOO.util.KeyListener to attach to a specific element and have also created another new YAHOO.util.KeyListener to attach to the entire document. They are both associated with the enter key (keys:13).

In the handler function for the listener attached to the specific element, I have the following code:

            getDetailsLocalnameInput = function(e) {
                    getDetails(localnameInput.value);
                    YAHOO.util.Event.preventDefault(e);
                    YAHOO.util.Event.stopPropagation(e);
            };

Yet, the event from the keypress continues to propagate up to the key listener attached to the entire document. I do not want the handler for the key listener attached to the entire document to get kicked off. I am sure that both handlers are being called, but only want the handler attached to the specific element to run.

Is it correct to use YAHOO.util.Event.stopPropagation with YAHOO.util.KeyListener?

Is there a different way I should go about preventing the keypress event from being propagated?

I have also tried using the function YAHOO.util.Event.stopEvent and setting e.cancelBubble with no success.

I have been testing all of this with Firefox 3.5. I cannot get stopPropagation() to work at all.

尝试这个：

 getDetailsLocalnameInput = function(e) {
     getDetails(localnameInput.value);

     if(window.event){
         e.cancelBubble=true;//In IE
     }else{
         evt.stopPropagation();//in Others
     }

     //YAHOO.util.Event.preventDefault(e);
     //YAHOO.util.Event.stopPropagation(e);
 };

Try this:

 getDetailsLocalnameInput = function(e) {
     getDetails(localnameInput.value);

     if(window.event){
         e.cancelBubble=true;//In IE
     }else{
         evt.stopPropagation();//in Others
     }

     //YAHOO.util.Event.preventDefault(e);
     //YAHOO.util.Event.stopPropagation(e);
 };
