Question

我今天开始使用Polymer，我对我用它所取得的成就感到非常兴奋！但是我偶然发现了一个我不知道如何解决的问题，如果在<paper-input floatingLabel>内添加<paper-dialog>，则纸质对话框会丢失很酷的动画。有任何已知的解决方法来获取动画，或者当动画组件位于另一个动画组件中时这是一个已知问题？

当我收到投票结果时，我决定提供代码来帮助人们帮助我：

<!DOCTYPE html>
<html>
<head>
    <!-- 1. Load platform.js for polyfill support. -->
    <script src="bower_components/platform/platform.js"></script>

    <!-- 2. Use an HTML Import to bring in the element. -->
    <link rel="import" href="bower_components/core-icons/core-icons.html">

    <style shim-shadowdom>
        /* Coloquei Junto com os inputs */
        body {
            font-family: RobotoDraft, 'Helvetica Neue', Helvetica, Arial;
            margin: 0;
            padding: 24px;
            -webkit-user-select: none;
            -moz-user-select: none;
            -ms-user-select: none;
            user-select: none;
            -webkit-tap-highlight-color: rgba(0,0,0,0);
            -webkit-touch-callout: none;
        }

    </style>


</head>
<body unresolved touch-action="auto">

<core-toolbar style="background-color: #f5f5f5">
    <span flex>
        <img src="images/logo_Positivo.png"/>
    </span>
    <paper-button label="Login" class="colored" onclick="toggleDialog('paper-dialog-transition')"></paper-button>
</core-toolbar>

<paper-dialog heading="Login" transition="paper-dialog-transition" style="background-color: #efefef">
    <div>
        <img src="/images/academia.png" class="gym_logo"/>
        <img src="/images/default_user.png" class="usr_logo"/>
    </div>
    <!--<paper-input floatingLabel label="Chave"></paper-input><br/>-->
    <paper-input floatingLabel label="Usuário"></paper-input><br/>
    <paper-input floatingLabel label="Senha"></paper-input><br/>

    <paper-button label="Entrar" class="colored" affirmative default onclick="document.querySelector('#toast3').show();disparaLogado();"></paper-button>

</paper-dialog>

<paper-dialog heading="Login" transition="paper-dialog-transition" id="logado">

    Logado!!!

</paper-dialog>

<paper-toast id="toast3" class="capsule" text="Acessando o sistema e validando dados..." style="padding-right: 60px;" duration="5000"></paper-toast>
<script>
    function toggleDialog(transition) {
        var dialog = document.querySelector('paper-dialog[transition=' + transition + ']');
        dialog.toggle();
    }
    function disparaLogado() {
        selecionarModulos = window.setTimeout(function () {
            var logado = document.querySelector('paper-dialog#logado');
            logado.toggle();
        }, 5000);
    }
</script>
</body>
</html>

我在paper-dialog-transition.html的末尾添加了以下行：

<paper-dialog-transition id="paper-dialog-transition" transitionType="fade"></paper-dialog-transition>

感谢您提供任何帮助或评论！

Answer 1

从您的代码中我不确定您是否尝试过此操作，但它确实帮助了我：

<paper-dialog transition="core-transition-bottom">

现在我回复了动画。可以在core-transition demo page中找到transition属性的可能值。

希望它有所帮助

Answer 2

我一直遇到动画问题，所有这些都是通过在过渡需要时将绝对位置固定到元素来解决的。
