Question

我是一个聚合物组件，从其中一个功能内部我想向用户显示一个对话框。我尝试使用dialog-paper，如下所示：

<template>
  <link rel="stylesheet" href="../themes/the-graph-dark.css">
  <link rel="stylesheet" href="../themes/the-graph-light.css">
  <div id="svgcontainer"></div>
  <paper-dialog heading="Title for dialog" id="dialog">
    <p>Lorem ipsum ....</p>
    <p>Id qui scripta ...</p>
    <paper-button label="More Info..." dismissive></paper-button>
    <paper-button label="Decline" affirmative></paper-button>
    <paper-button label="Accept" affirmative autofocus></paper-button>
  </paper-dialog>
</template>
...
eventHandler: function(event) {
  this.$.dialog.toggle();
  console.log(event);
},

当我在调用eventHandler时尝试切换对话框时，没有显示任何内容，我得到Uncaught TypeError: undefined is not a function。

在组件中显示对话框的适当方法是什么？

Answer 1

像这样

Polymer({
  that: this,
  ready: function(){
      addEventListener('on-blabla-event', function(event){
        that.$.dialog.toggle();
        console.log(event);
      });
    }
});
