触发 ondblclick 时阻止 onclick

堆栈溢出世界！

我有 h:panelGrid，包含一些元素。

我想在用户单击它时触发一个操作，并且我想在双击它时触发另一个操作。

我现在有以下代码：

<h:panelGrid ...>
  <a4j:support event="ondblclick" actionListener="#{page.doubleClicked}"/>
  <a4j:support event="onclick" actionListener="#{page.clicked}"/>
</h:panelGrid>

所以结果...... 当我点击它时，我得到了我需要的东西。但是当我双击它时，我收到了三个调用：单击，单击，然后双击。

所以问题是：当我们双击时如何防止两次单击调用？

我需要这两个动作。

stackoverflow world!

I have h:panelGrid, containing some elements.

I want to trigger an action when user clicks it and I want to trigger another action when use double clicks it.

I have the following code now:

<h:panelGrid ...>
  <a4j:support event="ondblclick" actionListener="#{page.doubleClicked}"/>
  <a4j:support event="onclick" actionListener="#{page.clicked}"/>
</h:panelGrid>

So the result...
When I click it, I got what I need.
But when I double click it, I got three calls: click, click and then doubleclick.

So the question is: how to prevent two click calls when we have a doubleclick?

I need both actions.
