这是一个老问题，但它最近又出现了;而这次它拒绝自己解决问题。 问题：当我点击“忘记密码”时，程序会立即更改状态，而不会播放转换。
转换代码：
<s:Transition toState="LoginForgotPassword" fromState="*" autoReverse="true">
<s:Parallel targets="{[loginExisting, passwordGroup, loginNew, whyTextLink, loginForgot]}">
<s:Fade duration="500" hideFocusRing="true"/>
</s:Parallel>
</s:Transition>
受影响的目标：
<s:states>
<s:State name="LoginMain"/>
<s:State name="LoginForgotPassword"/>
<s:State name="LoginRegister"/>
</s:states>
<s:Panel id="loginWizard" width="546" height="308" horizontalCenter="0" verticalCenter="0"
title.LoginMain="Log-in or create account" title.LoginForgotPassword="Forgot Password"
title.LoginRegister="New user registration">
<s:VGroup width="100%" height="80%" horizontalAlign="center" verticalAlign="middle">
<s:VGroup width="90%" height="85%">
<s:RadioButton id="loginExisting"
label="I'm already a member and I want to login with my Tarrigato account."
groupName="loginMethod" alpha.LoginForgotPassword="0.0"
visible.LoginRegister="false"/>
<s:HGroup width="100%" height="40" horizontalAlign="center">
<s:HGroup width="80%" height="40">
<s:Label height="40" fontSize="15" width="100" text="Username: " verticalAlign="middle"/>
<s:TextInput id="loginUsername" width="300" height="40" focusIn="loginFocusInHandler(event)"/>
</s:HGroup>
</s:HGroup>
<s:HGroup width="100%" height="40" horizontalAlign="center" id="passwordGroup" alpha.LoginForgotPassword="0.0">

</s:HGroup>
</s:HGroup>
<s:Spacer height="15"/>

<mx:LinkButton id="whyTextLink"

click="whyPanel.visible = true;" color="#B8B8B8"
textDecoration="underline" alpha.LoginForgotPassword="0.0"
visible.LoginRegister="false" includeInLayout.LoginRegister="false"/>
</s:VGroup>
</s:VGroup>
<mx:HRule y="218" width="100%"/>
<s:Button id="loginForgot" left="7" bottom="7" label="Forgot Password?"
click="currentState = "LoginForgotPassword";"
alpha.LoginForgotPassword="0.0"
visible.LoginRegister="false"/>
<s:Button id="loginCancel" right="126" bottom="7" label="Cancel"
click="currentState = "LoginMain";"

<s:Button id="loginContinue" right="7" width="115" bottom="7" label="Continue"

</s:Panel>
答案 0 :(得分：1)
您已将<s:transition>放入<fx:Declarations> - 它应位于<s:transitions>内。
你有：
<fx:Declarations>
<s:Transition toState="LoginForgotPassword" fromState="*" autoReverse="true">
<s:Parallel targets="{[loginExisting, passwordGroup, loginNew, whyTextLink, loginForgot]}">
<s:Fade duration="500" hideFocusRing="true"/>
</s:Parallel>
</s:Transition>
</fx:Declarations>
这应该实现为：
<s:transitions>
<s:Transition toState="LoginForgotPassword" fromState="*" autoReverse="true">
<s:Parallel targets="{[loginExisting, passwordGroup, loginNew, whyTextLink, loginForgot]}">
<s:Fade duration="500" hideFocusRing="true"/>
</s:Parallel>
</s:Transition>
</s:transitions>
在声明之外使用过渡数组。
除此之外，我做的唯一更改是将“passwordGroup”的id放在包含密码Label和TextInput的HGroup中。您只在转换的目标中使用了密码TextInput，并且没有包含TextInput的Alpha状态。
