Question

我正在尝试重新创建我在another site上找到的效果。当您将鼠标悬停在灰色标题区域上方时，会显示一个向下滑动的菜单。

我遇到的问题是，当我将鼠标悬停在该区域上时，hiddenNav容器会立即出现并且没有很好的移动效果。

这是我目前的代码

问题出现在targets属性中 - 在那里提到Group是没用的，这里修复了你的代码：

<?xml version="1.0" encoding="utf-8"?>

           xmlns:s="library://ns.adobe.com/flex/spark"
           xmlns:mx="library://ns.adobe.com/flex/halo" xmlns:mx1="library://ns.adobe.com/flex/mx" currentState="normalMenu">
    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>

    <s:states>
        <s:State name="normalMenu"/>
        <s:State name="hiddenMenu"/>
    </s:states>

    <s:transitions>
        <s:Transition id="myTransition1" fromState="*" toState="*" >
            <s:Sequence id="t1" targets="{[o0, o1]}">
                <s:Move duration="600"/>
            </s:Sequence >
        </s:Transition>
    </s:transitions>

    <s:HGroup x="0" y="33" id="visibleNav" width="100%" height="24" gap="0">
        <s:BorderContainer width="20%" height="100%" borderVisible="false" backgroundColor="#0000ff" >
            <s:Label text="HGroup Ipsum: " verticalCenter="0" left="10" color="#FFFFFF" fontSize="10"/>
        </s:BorderContainer>        
        <s:BorderContainer width="100%" height="24" borderVisible="false" backgroundColor="#005C3F" >
        </s:BorderContainer>
    </s:HGroup>

    <s:Group id="hiddenNav" alpha="0.9" x="0" y="0" width="100%" mouseOut="if(event.stageY>60)currentState='normalMenu'">
        <s:BorderContainer id="o0" width="100%" height="25" borderVisible="false" backgroundColor="#00110B" y="-20" x="0" y.hiddenMenu="33" y.normalMenu="-20">
            <s:Label text="hiddenNav Lorem Ipsum" x="0" y="0" color="0xFFFFFF"/>
        </s:BorderContainer>
        <s:BorderContainer id="o1" width="100%" height="25" borderVisible="false" backgroundColor="#ffff00" y="5" y.hiddenMenu="58" y.normalMenu="5">
        </s:BorderContainer>
    </s:Group>

    <s:BorderContainer x="0" y="0" width="100%" mouseOver="currentState='hiddenMenu'" height="32" borderVisible="false" backgroundColor="#848484" >
