尝试在单击纸张按钮时打开此纸张对话框，但它似乎不想在 Chrome 之外工作。我觉得这个问题与它在 dom-repeat 中的事实有关，但我不确定你能给我的任何帮助都会非常感激。我在 Safari 中遇到的错误是“TypeError: dialog1.toggle() is not a function. (In 'dialog1.toggle()','dialog1.toggle' is undefined)”。在 Firefox 中，我刚刚收到“TypeError：dialog1.toggle 不是函数”。这是我的代码，希望有人能指出我正确的方向。

使用getElementById似乎工作正常。这是在 Firefox 中为我工作的代码。希望它也适用于野生动物园

<template is="dom-bind">
 <template is="dom-repeat" items="{{data}}">
  <paper-button raised onclick$="toggleDialog({{item.id}})">{{item.series}}</paper-button>
  <simple-dialog id$="dialog{{item.id}}">
   <h2>{{item.series}}</h2>
   <p>{{item.data}}</p>
  </simple-dialog>
  <br />
 </template>
 <iron-ajax auto id="GetData" url="get_category_data.json" handle-as="json" last-response="{{data}}" ></iron-ajax>
</template>
<script>
 function toggleDialog(id){
  var dialog = document.getElementById('dialog'+id);
  dialog.toggle();
 }
</script>

旧线程，但我会为 Polymer1.0 添加上面的这个变体

<div>
    VAT check date: <paper-button value="paperbuttontest" raised on-tap="_paperDialogButtonEdit">{{buyer1.vat_check_date}}</paper-button>
    <paper-dialog id="vat_check_date_dialog_edit">
         <calendar-lite name="date.buyer1.vat_check_date" min-date="2017,3,1"></calendar-lite>
    </paper-dialog>
</div>

在聚合物中

_paperDialogButtonEdit: function (event) {
//console.log(" event.target = ",event.target.getAttribute('value'));
var dialog = document.getElementById('vat_check_date_dialog_edit');
dialog.toggle();
},
